‘It is not necessary, in order to make great
progress in the cure of cancer, for us to
-
have the full solution of all the problems
of basic research... the history of medicine
-
is replete with examples of cures obtained
years, decades, and even centuries before
-
the mechanism of action was understood for
these cures’ - Sidney Farber, United States
-
Congress, 1971
-
In 1971, when President Nixon declared war
on cancer, 1 in 30 of us would develop cancer
-
in our lifetime. Today that figure is 1 in
3.
-
Longer lifetimes account for a large part
of this change, but dramatic changes in our
-
food chain and lifestyles contribute to this
epidemic, with the world health organisation
-
forecasting a 75% increase in cancer cases
by 2030. Conversely, the cold fact is that
-
despite trillions being spent on research,
we have not cured a single cancer since the
-
1970s. If this is a war on cancer, then we
are staring defeat in the face. We are little
-
closer to overcoming metastasis or malignancy,
the holy grails of oncology, than we were
-
50 years ago. Is it possible that a tiny colony
of malignant brain cancer survivors, the most
-
deadly of all cancers, hold the key to a dramatic
improvement in all cancer therapies tomorrow?
-
Could the next great stride forward in the
field of oncology be simply a change in strategy
-
as opposed to a new drug or technology? And
what happens if that change in approach directly
-
contravenes established medical practice,
and the entire clinical trial structure we
-
have built for testing cancer treatments?
-
I think that many of these brain tumours and
other kinds of cancers are treatable. I just
-
think that a mountain of evidence is being
over looked.
-
If you face this disease and say from the
get go that it is incurable, you will always
-
be right, all your patients will die, and
you have no business treating those patients
-
in the first place.
-
They’re trying to protect people. They inadvertently
get into a situation where they kill people.
-
I would not be alive today if I had listened
to the only to the advice of my oncologist.
-
Because as one point he told me that, ‘Well,
you should try to consider just staying home
-
now and playing with your little daughter
while you can and not pursue any aggressive
-
treatments’ … but I decided otherwise.

Surviving Terminal Cancer
-
The Everest of oncology
-
The
brain poses unique challenges for clinicians:
due to its control of every single process
-
in our bodies, it is very difficult to remove
meaningful parts of tissue without removing
-
meaningful functionality from the human being.
This limits the reach of surgery, radiotherapy
-
and multiple biopsies, some of the most efficacious
tools at the oncologists’ disposal today.
-
Furthermore, the brain sits flush within a
fixed volume cavity - the skull - and so the
-
swelling that is the by-product of carcinogenosis
is frequently the primary cause of death in
-
brain tumour patients as inter-cranial pressure
builds relentlessly. Finally, clinicians treating
-
the brain face a unique impediment in something
called the blood brain barrier: a natural
-
and virtually impenetrable biological coat
of armour which protects brain cells from
-
infections circulating in the body. If we
didn’t have such protection then a simple
-
cold could easily end our life. However, when
placed in the context of cancer, this protective
-
coat of armour makes it difficult to get chemotherapy
into the brain. These three aspects of neurology
-
make clinical practice in the field of neuro-oncology
the most severely challenging of any in oncology
-
today. Compared to other cancers, brain cancer
has a very low profile, and yet it claims
-
more young lives than any other cancer. Nobody
survives it’s most aggressive and lethal
-
form, glioblastoma multiforme, referred to
in medical circles as ‘the terminator’.
-
Part of this is because of the difficulty
we just described in treating the brain. But
-
brain cancer itself is differentiated from
more common cancers by it’s cellular heterogeneity:
-
this means it’s highly differentiated cell
populations are inherently complex and varied,
-
and so simple targeted treatments affecting
only some areas can not impact it’s overall
-
ability to mutate and proliferate. A complex
problem calls for a complex solution, and
-
biological heterogeneity demands therapeutic
heterogeneity: or more simply brain cancer
-
is telling us that each patient is has a different
disease, and that they need a different cure.
-
This genetic instability is the hallmark of
all cancers. In this sense, cancer is the
-
most terrestrial of diseases, starting as
a simple malfunction of a living organism,
-
it demonstrates the same remarkable capacity
for adaptation and change, that has defined
-
of all the great survivors of evolution. It
is this ability to modify it’s DNA structure
-
from generation to generation that results
in the phenomenon referred to as drug resistance
-
- the principal barrier to treating cancer.
All of these facts, the limitations of traditional
-
intervention methods when dealing with the
brain, cancer’s most sinister characteristics,
-
and then additional problems specific to brain
cancer, are acknowledged and agreed upon by
-
every hospital and every expert in the world.
The tragedy for brain cancer patients today
-
is that the care they will receive does not
come close to reflecting the scientific knowledge
-
now at our disposal. This is where the problems
facing brain cancer, if they could be solved
-
today, could revolutionise the treatment of
all cancers tomorrow.
-
‘A round trip to Hades’
-
In southern California an academic and scientist
has dedicated his life to pursuing better
-
outcomes for brain tumour patients since being
diagnosed himself in 1995 with the most aggressive
-
type of brain cancer, glioblastoma multiforme.
Given only a few months life expectancy, Professor
-
Emeritus Ben Williams was an extraordinary
patient, and now nearly two decades later,
-
he is an extraordinary survivor for patients,
his book Surviving Terminal Cancer is a source
-
of frank assessment and logical analysis of
all available treatment options, often lacking
-
from their own medical team. Every year, Ben
updates this invaluable source of information
-
making it freely available to any patient
surfing the internet via a national brain
-
tumour charity. His remarkable journey has
taken him from moribund patient, to highly
-
respected survivor and patient advocate.
-
When I was diagnosed with brain cancer I knew
almost nothing about the disease other than
-
that it is one of the worst medical diagnosis
you can get. My first reaction when I heard
-
of that was to basically have a shiver down
my spine because I knew I probably didn’t
-
have much chance of surviving. I hadn’t
even heard of a glioblastoma at that point.
-
I was told that it was the worst kind of tumour
you could have and that nobody survived it.
-
For the first couple of weeks after that I
was just in shock. I mean there was no other
-
way to describe it.
-
Ben was told he could expect to live for 12-18
months if he was lucky, and that the chemotherapy
-
treatment available to him would not save
his life.
-
For the first several months, most of my thinking
was, you know well, I’m going to die. How
-
am I going to deal with it? And I thought
a lot about death. The treatment was just
-
sort of something I was just following along
because I didn’t know any better at that
-
point. There were no options that were presented
to me. What you are faced with is well, I
-
don’t really have a choice. This is going
to kill me and I better try and figure out
-
how to make that as easy a process as possible.
-
Like all patients Ben was prescribed the standard
of care: immediate surgery, followed by intensive
-
radiation and chemotherapy.
-
When you receive a diagnosis that every one
tells you is terminal - that no one survives
-
it - it’s impossible not to become depressed
by that information. I mean I look at pictures
-
from that period of time and I mean, clearly
I was depressed and it wasn’t until I began
-
doing research that said there was a possibility,
that there are things you can do that would
-
be helpful and I began to think - well this
is worth at least making the fight. And the
-
more information I began to find, the less
depressed I became, and the more optimistic
-
that things were not nearly as terrible as
everyone was telling me.
-
However, before the era of the internet, Ben’s
task of educating himself quickly was considerable.
-
The first couple of months I basically did
nothing else but reading. It was a crash course.
-
I knew I didn’t really have much time to
do a comprehensive education so I was really
-
trying to find a shorthand account of what
I was dealing with. Unfortunately most of
-
the articles were every bit as discouraging
as what I had been told initially as they
-
almost all began with an introduction that
said glioblastoma is universally fatal. But,
-
the more research I did, the more leads that
I came across about things that had been ignored
-
and things that - at some early stage data
from clinical trials that really hadn’t
-
gotten much attention but still looked quite
promising and - it seemed like it was totally
-
sensible to try and add those things into
whatever else I was being prescribed to do.
-
So I found, you know, several different drugs
that had good evidence from medical literature
-
of benefitting people with cancer - some of
them specifically with brain cancer but others
-
with cancer in general. I mean things like
(immune stimulants) and things that were
-
used widely else where so that I found one
mushroom extract that was used in Japan routinely
-
in almost all cancer treatment protocols and
yet it is never mentioned in the United States.
-
It has zero toxicity. Why would you not use
it? I mean millions of people in Japan use
-
it. That’s a big mystery to me. How you
can just disregard something that has credible
-
evidence.
-
But Ben's line of thinking was met with surprising
opposition.
-
My neuro-oncologist raised the question - well
you don’t want to add these things because,
-
you know, they have a lot of toxicity and
I thought, well not from what I know about
-
them compared to what you’re about to give
me. And it turned out that while I had some
-
side effects of some of the things they were
really nothing of major consequence so I was
-
right about the idea that they were worth
trying.
-
With a PHD from Harvard and a chair as Professor
of experimental psychology at the University
-
of California, Ben had the courage of his
convictions, a critical tool the vast majority
-
of patients lack.
-
I realised fairly early that medical practice
is standardised for everyone and pays almost
-
no regard for the individual variability of
patients. When I first asked my oncologist
-
- my neuro-oncologist - if I could add the
first agent that I used - it was high dosage
-
Tamoxifen - to what he was offering in terms
of a chemotherapy program. He just out right
-
refused. He was unwilling to bend and we had
a major altercation over the phone and it
-
ended up with him basically saying that we
couldn’t work together and so whether he
-
fired me or I fired him, I was without a neuro-oncologist
at that time. But fortunately my neurosurgeon
-
intervened and convinced my neuro-oncologist
that maybe they should let me do a little
-
bit more in terms of participating in my own
treatment program than they would ordinarily
-
do. Eventually we got along quite well but
I never did really tell him everything I was
-
doing after that. Going against the advice
of my doctors was really initially an act
-
of desperation. I mean, I wasn’t concerned
about offending them, I was concerned about
-
staying alive and so I was going to use anything
I could get my hands on, and if that made
-
them angry, well that was too bad. At one
point I was going down to Mexico, to Tijuana,
-
to obtain a drug normally used for acne which
also had been shown to have some treatment
-
benefits for glioblastomas. I had to go to
Mexico because the drug required a prescription
-
and I knew it was going to be a great difficulty
obtaining it here so I was taking that all
-
along without the knowledge of my neuro-oncologist.
The irony was that when I eventually told
-
my neuro-oncologist what I had done, he said
to me ‘that was a very nice study that MD
-
Anderson did’ – he knew about it all along,
but it was not a part of the standard treatment
-
and so he’d never even mentioned the possibility.
In most cancer treatment protocols there is
-
a standard treatment that the oncology community
has agreed upon and they don’t deviate from
-
it except in the context of clinical trials.
That realisation, the beginning of my deep
-
anger about how the medical system was working
- It made absolutely no sense to me not to
-
use everything that might have a benefit as
long as the toxicities were acceptable. Why
-
wouldn’t anyone want to add them? It seemed
to me totally irrational that people didn’t
-
use everything that was available.
-
With this strategy Ben constructed a cocktail
of drugs around his chemotherapy. When his
-
MRI scans began to show his tumour gradually
reducing in size, and eventually disappearing
-
altogether 6 months later, it was clear that
something very unusual was taking place.
-
After my first round of chemotherapy I did
get a small amount of shrinkage in my tumour.
-
That was a tremendous weight that was lifted
off of me. I mean I didn’t feel of the kind
-
of depression that I had felt up until that
time. I mean, I was ready for the battle at
-
that point because it didn’t seem hopeless.
So I started adding even more things at that
-
point. And then after the second round of
chemotherapy I had a lot of progression in
-
the tumour, and then after the third round
of chemotherapy, a lot more. Then I had a
-
clean MRI after the fourth round. And I’ve
got clean MRIs ever since. People are always
-
raising the question - so this might have
worked for you, but maybe you were just a
-
rare case that responded to chemotherapy’?
Did any of these other things that you added
-
make a critical difference? The hallmark of
my case was that the chemotherapy did work
-
for me. I mean, I had something was different
about how I was getting the chemotherapy and
-
the things that went with it, and I had deliberately
focused on that. I mean, I though seriously
-
about where the resistance to chemotherapy
came from and how one might overcome it.
-
Now retired, Ben spends a great deal of his
time responding to the desperate enquiries
-
of patients who have read his book, offering
impartial advice whilst never advocating specific
-
treatments.
-
We’ll never know for sure why I’m still
alive. Certainly I did things that were unusual,
-
but, you know, I might have done things that
were unusual in terms of the characteristics
-
of my tumour. I don’t think that’s an
argument I take seriously now because I have
-
advised a lot of people over the years to
adopt a similar approach. They didn’t do
-
exactly what I did, but they added as many
things as they could to the standard treatment
-
- and many of them have had very good success.
The irony is that almost all oncologists agree
-
that multiple agent approaches are going to
be necessary to actually cure anything. And
-
so, no one really is disputing that. The question
is what goes into those cocktails and what
-
kind of criterion of evidence that you have
to have for putting those cocktails together.
-
To this day Ben still self-administers a maintenance
therapy: a daily cocktail of vitamins and
-
supplements designed to try and create as
hostile an environment as possible for cancer
-
to face in his body.
-
Logic Dictates
-
On the east coast of America, an advocate
of combination therapies is Dr Raymond Chang.
-
Pioneering the integration of oriental and
western medicine, his book Beyond the Magic
-
Bullet poses an uncomfortable question for
the oncology community.
-
Oncology thinking somewhat followed infectious
disease treatment thinking because the first
-
original breakthrough in achieving a cure
for any disease came in the infectious disease
-
field whereas possible with the discovery
of penicillin and so fourth. Single antibiotics,
-
single chemical (*) were able to eradicate
– cure, literally - serious medical conditions
-
like tuberculosis, like syphilis. That was
then applied to cancer with the same logic
-
behind it… well if we find the right chemical,
maybe we can eradicate cancer just like we
-
can eradicate tuberculosis… and then that
mode of thinking dominated (*) therapy for
-
over a century at least. We think that most
diseases, if you simply find the right key,
-
you should be opening the door, and the reason
why the door remains locked - the cure remains
-
locked - is because we don’t have the right
key. So we should keep looking for new keys
-
or try to improve the key that we have and
we will eventually open the door. What if
-
this door has multiple locks? When you keep
looking for one key, it’s not going to open
-
the door no matter how hard you look. It will
never, it will fail, the whole strategy of
-
research will fail! Then maybe the way of
thinking is wrong. It’s not that we need
-
better drugs, but we need to know better how
to deploy what we have already. If we have
-
‘cure’ or ‘control’ already in our
hands except that we’re not using things
-
properly.
-
As proved to be the case with childhood Leukaemia
and aids, it was the combination of existing
-
treatments that delivered the breakthrough.
Today infectious disease treatments follow
-
this logic.
-
Hepatitis C, hepatitis B - chronic viral infection
- HIV obviously. They are all attacked with
-
multi(*), multi agent, multi target approaches
– and with success. Cancer treatments are
-
kind of behind… again. So hopefully it will
follow the lead of the infectious disease
-
practitioners.
-
The idea of a cocktail approach to cancer
treatment has gained adherence amongst the
-
oncology community.
-
I think that if we are going to try to treat
this disease we need to be using combination
-
therapy from the get go. Single agent therapy
is not likely to be very effective with a
-
disease with so many molecular (*) underlying
its ability to be invasive and resistant to
-
therapy.
-
What you want to design for a problem like
cancer is not a drug or an intervention. You
-
want to design a solution - because that’s
what patients want. So it’s a lot like your
-
computer: there’s amazing components in
there like your microprocessor or your hard
-
drive, but individually they aren’t worth
anything to you until they are put together
-
into an interoperable system that becomes
your laptop that’ll do word processing or
-
send emails… Now that’s of value to you.
Today in drug development and in clinical
-
research we need to be thinking of those kinds
of integrated, interoperable solutions.
-
With glioblastoma we’re really climbing
a mountain. Every therapy that we see a modest
-
success for gets us a little bit further up
the mountain then we set up a new base camp,
-
and then we come up with a another therapy
that gets us further up the mountain, set
-
up a new base camp. The concept of synergy
is really important here because what if we
-
could just get further, faster?
-
An example of why it is that combining different
treatments together is in fact the development
-
of what is now the standard of care: It used
to be that you used to receive radiation first
-
and then wait a month or so, and then start
on your chemotherapy. The new protocol is
-
that you have the radiation and the chemotherapy
together. It has produced a better outcome.
-
Clearly the change of putting them together
simultaneously as opposed to sequentially
-
was a step in the right direction.
-
Current management of brain cancer as well
as many other cancer conditions involves a
-
multi disciplinary approach where surgery
is deployed, radiation is deployed, chemotherapy
-
is deployed, and targeted therapies are deployed.
So one can argue that it is already, in a
-
way, it’s already mixed or cocktails and
not just one single therapy… But, much more
-
can be done. Many other drugs can be used
without much toxicity without much even cost.
-
Simple, simple drugs.
-
Although there is general consensus of the
advantages of the cocktail approach, there
-
is disagreement about how much information
is needed to start combining untested treatments
-
together. How far and how fast this can be
taken for individual patients is the fundamental
-
issue.
-
The big problem with cancer treatment is that
the tumour develops resistance. I mean, you
-
know, so it’s usually that the treatment
is only partially effective in the beginning
-
- at best - and what you then get in an evolution
of resistant strains of the tumour, and so
-
the more you treat it, the more resistant
it gets just through the process of evolution.
-
The biggest risk in all of this is you’re
going to be dead very quickly from your tumour
-
unless you do something other than what is
being offered from the conventional medical
-
treatment.
-
We always balance the potential gain with
the potential toxicity of an agent and making
-
a decision whether to include it and if so,
how to include it and when to include it…
-
but we’re not treat colds, we’re treating
glioblastoma… and what risks you might take
-
with a cold are going to be far less than
the risks you are willing to take with someone
-
with a glioblastoma when you know the natural
outcome is so dire.
-
It is clear that cocktail therapy represents
an excursion into the unknown, with corresponding
-
uncertainties about the risks involved.
-
Some of these cocktails involving 10 or more
substances can have life threatening complications
-
and for the safety of the patient it would
be much better if the physician knew about
-
it and could appropriately follow. There can
be some aggressive attitude of some physician
-
starts experimental treatments especially
with free purpose, non approved drug cocktails.
-
And I can very well understand that patients
may try to avoid this conflict with a treating
-
physician and I think that the solution is
on the side… lies on the side of the physician.
-
Resistance
-
Treating malignant brain tumour patients is
not easy for physicians. Most do not become
-
doctors to watch all their patients die. At
the sharp end of this scale lies paediatric
-
neuro-oncology. In Belgium, one man’s professional
crusade against brain cancer has led to his
-
university hospital becoming the most advanced
centre in Europe for immunotherapy in brain
-
cancer. When not fund-raising out of hours
to support his research programmes, Professor
-
Stefaan Van Gool is on the very front lines
of neuro-oncology, taking the fight patient
-
by patient.
-
Personally I think the prognosis of the patient
is the worst when the doctor does not treat.
-
There is nothing. If there is one thing frustrating
that is that you want to fight for your patient
-
but that you face borders that are aimed to
be protecting patients, but are sometimes
-
also not protecting patients because they
block progression. Evidence based medicine:
-
you do an intervention, compare to control
- but if this intervention consists of five
-
new factors… that will be a hard one to
do, but maybe these 5 (*) factors are needed
-
to make the progression. That’s the difficulty
more and more. You have to fight against all
-
the barriers with (*) committees, with regulatory
authorities, which makes thinking out of the
-
box more and more difficult. If we come too
much into fixed system: phase one, phase two,
-
phase three, phase four, and that’s it.
That will reduce progression - certainly if
-
you want to elaborate multi model, more holistic
approaches. That’s very difficult and unfortunately,
-
at the moment, it becomes more and more difficult.
-
The reality facing the vast majority of patients,
is that their doctor will not engage with
-
any experimental therapy outside of a clinical
trial, even in the context of a terminal diagnosis.
-
We wanted to try and understand the reasons
behind this seemingly unnecessary resistance.
-
Realistically there are other practices beyond
medicine. It has to do with capitalism, it
-
has to do with health care structures, systems
and so fourth. Mono therapy is easier to carry
-
out. If something goes wrong, it is clear
what’s wrong because you’re giving one
-
treatment at a time so if the patient has
a server side effect it’s that treatment
-
- it’s that drug. Regulatory wise, it’s
very difficult to get studies going involving
-
multiple agents, because let’s say if you’ve
got five agents - instead of testing one thing
-
at a time then you have to test A against
B plus C plus D plus E or, A plus B against
-
C plus D plus E. There are then, to the power
of five, so many different variations possible.
-
That means you have to do so many studies.
Practically it’s almost impossible to study
-
these things if it becomes complex. So a simple
monotherapy approach is easier, cleaner for
-
management purposes - but it may not be as
effective. It is unconscious because doctors
-
don’t necessarily think about it, but they
implement it in this fashion. This is the
-
way how studies are done. You don’t put
patients on three new X, Y, Z unknown new
-
treatments at the same time because the issue
always comes up that well, if it works, what
-
did it? Then we don’t know. That is not
acceptable to science. You have to be careful
-
that the doctors need to be scientific…
but when you’re treating the patient, is
-
it for science or is it for the patient? Sometimes
we forget.
-
Other obvious candidates for cocktails are
natural compounds. These naturally occurring
-
substances cannot be protected by patent and
so no one company can gain a monopoly over
-
their supply. Totally non-toxic, and with
years of data to prove its efficacy in cancer
-
care, curcumin should be an obvious adjuvant
for any cancer protocol, and yet it is rarely
-
used in western medicine. We travelled to
the world’s largest specialist cancer hospital,
-
MD Anderson in Houston, where the series of
laboratories dedicated to natural compounds
-
are testament to the holistic vision behind
the Texan project.
-
As of today there have been over 150 clinical
trials that have been completed. And the answer
-
is yes it works and it down modulates bio-markers.
You know, there are only 20-25 driver genes,
-
and that I have taken all those driver genes
and asked ‘are they down modulated by curcumin?’
-
Because that is what the drug industry is
targeting…and the answer is yes: curcumin
-
alone, has over ninety different targets,
ninety different targets, it is not just a
-
mono-targeted. So this is what the drug industry
calls a ‘dirty drug’. Any drug that hits
-
more than one target is a dirty drug for them,
they don’t like it. There are only two rules
-
of the game that I have learnt from my days
in Genentech (and there is no third that I
-
know of) .. Safety: number one, whatever you’re
giving to the patients should be absolutely
-
safe, it shouldn’t hurt them in any way.
Second is the efficacy. There is no third
-
rule, and curcumin meets both of them.
-
But as any cancer patient will testify, there
is huge opposition from the medical establishment,
-
towards adding natural compounds to traditional
cancer treatments. The reason most patients
-
are given, is that it ‘may interfere with
your treatment’ although only in rare cases
-
is there any evidence to support this claim.
-
In medicine today, there is a buzz word and
that is called ‘targeted therapies’. Targeted
-
therapy means you pick a single gene, a single
protein, and you try to find an inhibiter.
-
That is what they call a ‘magic bullet’.
They have come up with a lot of magic bullets.
-
Only thing is, these are not bullets and these
are not magic, so there is a lot of frustration,
-
asking where did we go wrong? Where they did
go wrong was thinking that cancer is a single
-
gene or single protein - a single target disease.
By now, we are living in the era of ‘omics’:
-
genomics, proteomics, metabolomics, and all
of that is out there to tell you that cancer
-
is a multi-genic disease. No matter which
direction I look at, people’s mind is set,
-
and their mind is set on targeted therapies.
They want a targeted therapy, if it is not
-
targeted they are not interested, period.
It doesn’t matter whether it does anything
-
good for the cancer or not, they are not interested…
and that’s where I face the biggest resistance.
-
I have people tell me point blank in my face,
right here in MD Anderson. They say, ‘well
-
Dr Aggarwal, anything you do with respect
to natural products I don’t believe even
-
one bit of it. They don’t even want to read…
and we publish in the same journals. We are
-
most highly cited. People don’t want to
read. There’s this, you know, in born bias.
-
My problem with the ethics of oncologists
is that they want to pre-empt the decision
-
and they don’t their patients have any leeway
in making a decision that sort of kind of
-
moves them in the direction of alternative
medicine. It’s a real concern on their part.
-
I mean, professional reputations can quickly
be ruined if you’re viewed as one of those
-
kooky guys who goes around trying to throw
out anything under the sun into your treatment
-
protocol.

History is littered with scientific breakthroughs
that were castigated for their implications
-
for the prevailing status quo. When Copernicus
introduced his heliocentric theory to the
-
world, the shock to the belief system reverberated
for centuries afterwards: Gallileo Gallilei
-
was persecuted for his acknowledgement of
Copernicus’ theory and his pursuit of a
-
new rational science in its wake. Even Gallileo’s
presentation of his new invention, the telescope
-
and it’s irrefutable new evidence, could
not dampen the fervour of his condemnation.
-
In the nineteenth century, Ignaz Semmelweis,
a relatively unknown doctor, a Hungarian practising
-
in the venerated hospitals of Vienna at its
empirical peek, noticed an alarming correlation
-
between the new practice of pathology, and
the advent of a series of deaths of both mothers
-
and babies in the maternity wards of those
same hospitals. His suggestion that perhaps
-
his fellow surgeons should consider using
chlorine to wash hands before operating on
-
patients, was met with vicious resistance.
Unable to substantiate his theory scientifically,
-
Semmelweis was ostracised professionally by
his peers for daring to question the status
-
quo. He died 15 years later in a mental institution,
a broken man, yet a century and a half later
-
he is venerated as a national hero in Hungary,
where statues and coins carry his legacy as
-
the father of sterile medicine. Today, the
Semmelweis reflex is a term used to describe
-
an illogical and exaggerated response to a
challenge to the prevailing dogma. Unfortunately
-
- the Semmelweis reflex is alive and well
in today’s medical establishment: Barry
-
Marshall, a little known doctor from Western
Australia, had identified a bacteria in the
-
early 1980s that indicated stomach ulcers
were caused by bacteria. This was heresy to
-
the established thinking in the field of endoscopy,
which was convinced that stomach ulcers were
-
caused by stress. As a result Marshall’s
thesis was not published in any medical journals
-
and sat on the shelves gathering dust while
hundreds of thousands of patients across the
-
world had their stomachs removed, unnecessarily
so according to his theory. With the bacteria
-
in question only able to develop in primates,
but with testing on primates prohibited, the
-
successful animal experiments that the medical
establishment deemed pre-requisite for Marshall
-
to progress to human trials, could thus never
be completed. So locked out of both animal
-
and human experimentation, but convinced of
his theory, Marshall chose to experiment on
-
the one human he did have legal access to:
himself. In front of an audience of stunned
-
peers, he downed a petri dish full of bacteria
grafted from a patients’ stomach, and claimed
-
to have infected himself with a stomach ulcer.
The proof duly came, as did his cure without
-
the need to remove his stomach, swiftly followed
by an avalanche of awards and praise from
-
the establishment, culminating with the Nobel
Prize in 2005. Beyond the more obscure issue
-
of medical hegemony, lie more obvious reasons
for why combination therapies do not reach
-
patients.
-
If you have: a drug A from company A, and
a drug B from company B, and a drug C from
-
company C, it is extremely difficult to get
all three of those drug companies together
-
to agree to use their drugs to treat a particular
disease process. It’s much easier if the
-
drugs all come from one company… and that
is a fundamental challenge that not just neurosurgical
-
patients with glioblastoma face, but all cancer
patients face. And from the company stand
-
point one could make a good argument that
it’s reasonable and understandable that
-
this is the case because they invest hundreds
of millions, sometimes billions of dollars
-
to develop that drug, and as that drug comes
to market it goes to the FDA, the application
-
of that drug to other disease processes in
combination with other drugs could cause a
-
lot of problems for them. So it’s a very
difficult thing to address.
-
On top of the reluctance of western medicine
to consider natural products as they cannot
-
be patented, for the very same reason, drugs
whose patent has expired are similarly discarded
-
as they cannot guarantee a return on the investment
required to run a clinical trial. This results
-
in a large number of drugs with strong laboratory
evidence for anticancer properties never getting
-
anywhere near patients. In some cases, even
when human trials have been run it is still
-
not enough to bring the drug into the mainstream
treatment.
-
A very nice example is the use of the old
malaria drug which is dirt cheap, Chloroquine,
-
for brain cancer where nice trials have been
carried out showing improvements up to 50%
-
survival time when it’s added to standard
chemotherapy. It has almost no side effects.
-
It’s one pill a day. It does not mean the
patient has to suffer going to the hospital,
-
get a drip, any of this. It’s dirt cheap.
Why not? Well, FDA has not approved its use
-
for this condition - for one. The information
is not widely disseminated. There’s no big
-
drug company behind the manufacture of chloroquine
to market it for this use. Nobody makes much
-
money if suddenly every brain cancer patient
starting taking chloroquine, it adds very
-
little to the bottom line of any particular
business or company.
-
So it is more and more important for us to
look at these drugs that have been left on
-
the shelf, that big pharma wants nothing to
do with, but we don’t initially have the
-
time or the resources to provide the data
managers, the IRB fees and start up fees that
-
it takes run a good clinical trial.
-
Aside from the influence of the medical world
status quo, and the economic reasons hampering
-
development of combination therapies for cancer,
there is a strong feeling amongst the patients
-
we interviewed as to why oncologists are unwilling
to deviate from established best practices,
-
even in the context of terminal disease.
-
One of the problems from a patient’s perspective
is that they want as many drugs as possible
-
to facilitate long tern survival, and that’s
a very reasonable request from the stand point
-
of a patient. If you have cancer, you hear
a certain drug might be effective in your
-
particular type of cancer, you want to access
that drug. You hear that another type of drug
-
might be effective, you want to actually just
go ahead and combine those drugs, and so fourth
-
and so on. From a patient’s perspective,
you are entitled to pursue any type of therapy
-
you want to. From a provider’s perspective,
from a neurosurgeon, a scientist, from a a
-
neurosurgical oncologist’s perspective,
we have to be very, very careful about what
-
we recommend to patients in terms of going
after therapies that are unproven.
-
Doctors are judged by so-called standards
of practice in the community. So, if in California
-
this is the way we do things, here, in LA,
this is the was we do things… and you do
-
it differently and the patient gets hurt,
and you’re in court, they will summon your
-
peers and say well, how do you do things usually?
And every body says ‘I don’t use Temodar,
-
I don’t do Temodar + chloroquine
-
This issue of liability is one of the silent
enemies in the war on cancer. Drs and hospitals
-
who would willingly take more risks for their
patients who have run out of options, are
-
discouraged from doing so by fear of malpractices
suits. This fear of prosecution is not limited
-
to doctors, but runs deep through the entire
system, dissuading individuals and teams from
-
doing anything outside of the box for their
patients.
-
The specialists are at major cancer institutions
that does not treat patients as individual
-
unlike what patients may think. They treat
as a group. They can call it a team approach,
-
but they treat by committee, literally there
is a committee of doctors who review cases
-
– it’s called a tumour board – and almost,
you can imagine, 6,7 specialists at the centre
-
every week, sit down and go over new cases
and decide ‘this is what we’re going to
-
do.’ Now, that also creates an issue because
then everybody has to agree for one, then
-
of course what everybody agrees on in any
bureaucratic structure has to be the lowest
-
common denominator. Okay? But that’s the
safest way for the doctors and the hospital
-
because if there was a problem, and if the
was a charge, they say well, ‘six specialists
-
had a committee meeting on the same week – and
we all agreed… you want to sue six of us?
-
And we represent the hospital are you going
to sue the whole hospital for this decision?
-
every one of our patients get exactly the
same thing. What’s wrong with this? We are
-
following the guide lines from the American
cancer society’. So, everything is therefore
-
protected, protected, protected… for liability
reasons. So it’s fool proof. If you try
-
to be individualistic, stick your neck out,
give chloroquine because there’s a paper
-
that says give chloroquine, and something
goes wrong, you don’t have anything backing
-
you up in the court of law. It’s much safer
to follow a protocol. A protocol is one thing
-
at a time until it’s proven otherwise. The
proof may never come because there is no funding
-
to try to prove these things. Who gains from
proving them? Who is going to fund the proving
-
of this? These are much larger issues that
I think will hamper developments of true cocktails
-
unless there is radical changes in health
care systems and social systems. It may not
-
come.…
-
Lightening doesn’t strike twice
-
Ben's Williams book is nothing more than a
blueprint for anyone who wants to follow a
-
more pro-active approach to their own treatment.
One such patient was Richard Gerber, a fellow
-
American academic living in Italy, who was
diagnosed with the same lethal brain tumour
-
a decade after Ben. Given just months to live,
Rich had nothing to lose.
-
During the chemotherapy and radiotherapy that
I had – although it was very exhausting
-
– I started reading at night, articles and
journals, and I realised that therapy was
-
not going to really make my life any longer
so I started doing research into alternatives,
-
and little by little, on the internet, I came
across this name ‘Ben Williams’ who had
-
written a book. I ordered the book. And it
basically is teaching people to take their
-
matters into their own hands and to be their
own doctors in part. So far, this cocktail
-
approach that he writes about in his book
has proved efficacious for me. I wasn’t
-
just blindly following Ben. In fact, I wouldn’t
have followed Ben at all if his arguments
-
weren’t logically convincing.
-
In common with Ben, Rich shared a scientific
background, he is an expert at developing
-
solutions for complex problems.
-
I took what we call a ‘black box’ concept
that is glioblastoma is a very, very complicated
-
phenomenon. Nobody knows: how it works, how
it grows, how it gets started, how the therapy
-
works, and papers are published on very specific
subjects and very specific genetic pathways,
-
but there is no integration of this information.
So, my approach was based on finding as many
-
agents which could block assorted pathways
which activate glioblastoma, and doing it
-
all at once so that the glioblastoma would
have less of a chance to mutate and escape
-
via a path way because I would already be
blocking that pathway.
-
Of course, assembling and consuming an unsupervised
and untested cocktail of drugs and neutraceuticals
-
is daunting even for someone with an in depth
appreciation of their disease. One of the
-
patients we interviewed equated it to playing
Russian roulette whilst on death row.
-
My doctor was a very sympathetic oncologist,
but she was very ‘by the book’. She didn’t
-
want me to do anything else. Coming up with
my own notions I suggested to this doctor
-
that I would like to take melatonin. I tossed
this out as sort of a test because at the
-
time I was actually taking 10 or 15 other
pharmaceuticals but I thought I would start
-
small and she didn’t want to hear about
it. She told me not to take melatonin, that
-
it would just confuse the matter. At that
point I realised that I was on my own because
-
if I couldn’t confess to my doctor that
I was taking melatonin, how could I confess
-
to her that I was taking chloroquine and (*) and
other pharmaceuticals. I didn’t add all
-
the ingredients at once. I added them incrementally.
I basically included any ingredient, be it
-
a supplement or a pharmaceutical that was
active against cancer and didn’t interfere
-
with the other ingredients. The pharmaceuticals
had to be dosed correctly, and the dosage
-
I used was that carried out in the research
paper on cancer that I found. You have to
-
read very closely these articles to get the
correct dosage – but it’s there.
-
At its peak his cocktail numbered over 25
different components, and in order to access
-
them all, Rich broke every rule in the book:
From feigning symptoms of other ailments in
-
order to access non-cancer drugs that he believed
may also act against his disease, to forging
-
prescriptions.
-
There were moments during my cocktail therapy
when I thought I was doing too much, and I
-
was getting out of my own comfort zone which
is nothing like medicine, but, I realised
-
that the alternatives were very small: either
I tried something much more radical than the
-
standard of care, or I would die. And when
you’re faced with that kind of decision,
-
why not use more ingredients?
-
Long term survivors of malignant brain tumours
are extremely rare. What makes Ben and Rich
-
even more unusual amongst this tiny data group,
is that they have never had a recurrence - their
-
cancer has never come back.
-
A glioblastoma can’t really be cured. Never.
I never think about cure and I don’t talk
-
to anybody about cure. I think that every
year that you live without a recurrence is
-
great. I think Ben Williams now has lived
eighteen years without a recurrence if I’m
-
not mistaken. I’ve lived six and a half
years without a recurrence. At that point
-
you can say that we’re under control, but
you can’t say that we’re cured because
-
there is always a possibility that it could
come back.
-
Ethics in question
-
After the horrors of the human experimentation
that characterised the holocaust, at the Nuremberg
-
trials the international community laid down
the founding principals of a clinicians ethical
-
obligation, initially referred to as the Nuremberg
code and later ratified in the Declaration
-
of Geneva as an extension of the Hippocratic
Oath. Building upon these foundations, the
-
world of medicine unilaterally subscribed
to the Declaration of Helsinki in 1964, and
-
its primary revision in 1975 that introduced
the principal of ethical review by an independent
-
committee. In doing so, the global medical
community enshrined the moral truth that ‘concern
-
for the interests of the subject must always
prevail over the interests of science and
-
society’. Can we honestly say that today’s
double-blind studies on terminal cancer patients
-
adhere to this principal?
-
Frankly, that I don’t know how a neuro-oncologist
could go home and look themselves in the mirror
-
at night given what he knows and the outcome
of his patients are. I just don’t think
-
it’s even ethical. I wouldn’t be able
to live just presiding over patients, just
-
giving them radiation and chemotherapy and
at the same time, knowing that they are all
-
going to die.
-
I think the general concern in the oncology
community is that this is a terminal disease
-
and when diagnosed with a GBM you are going
to die. I think that philosophy is kind of
-
counterproductive to doing anything meaningful,
so I think our goal is to put patients on
-
clinical trials to press the field forward,
but when you can’t do that, to do something
-
better than a standard of care which is palliative.
-
What we are fighting against is the negligence
that physicians are not aiming to inform themselves,
-
that they are not forming an opinion themselves.
-
If you face this disease and say from the
get go that this it is incurable - you will
-
always be right, all your patients will die
and you have no business treating those patients
-
in the first place.
-
I think it is one of the toughest situations
in everyday clinical work. This is a point
-
where it is really necessary to really explore
the patient’s wishes and really find out
-
if the patient is willing to take an additional
risk for a chance, for a possibility of having
-
a better (*). The problem is that a patient
who is asked to take an additional risk for
-
a chance to survive will almost always say
yes.
-
So the central issue is the question of protecting
patients rights at both ends of the spectrum:
-
whilst uninformed vulnerable patients need
protection from unreasonable offers of experimental
-
therapy at one end, equally should patients
at the opposite end of the spectrum, who do
-
not wish to accept a palliative standard of
care, be denied the right to fight for their
-
lives? When their doctors refuse to co-operate,
these patients inevitably find themselves
-
outside of the medical system. We wondered
how many other cancer patients have embarked
-
into unchartered territory of self-medication,
without their story ever coming to light.
-
In California, we heard of another desperate
struggle against terminal cancer. But for
-
Neil and Margo Hutchison, there was no happy
ending. neuroblastoma, a rare cancer of the
-
nervous system, claimed the life of their
eldest son Sam aged just 8 years old.
-
He was a very active little kid. Loved sports,
loved anything with balls, loved trucks, he
-
ran like the wind, we was a funny, great fantastic
kid. When he was four and a half we were at
-
a soccer game and he sat down and said ‘my
legs hurt’, and he always used to jump out
-
of our van and he started to sit down to get
out of our van so we that something was definitely
-
wrong. We decided to get some blood tests
and an X-ray and he was diagnosed with neuroblastoma.
-
55:38 N: Sam began one of heaviest chemotherapy
regimens used in medicine with accompanying
-
stem cell transplant that meant he lost his
hearing and would be sterile for the rest
-
of his life. But with such a high grade of
malignancy Neil and Margo were told Sam had
-
very little chance of surviving.
-
Well first off, I mean, you’re shocked,
I mean, I think even parents of someone diagnosed
-
with paediatric leukaemia would just, you
know, – it has a very high survival rate
-
– you know, it still it punches you in the
gut, but when they sit you down…
-
You’re just… yeah, you’re in shock for
months.
-
After the shock dissipates, the dislocation
between the patient’s perspective and that
-
of their medical teams was a common factor
in all the cases we covered during filming.
-
It is clear that while the Hutchison's have
both a deep respect and appreciation for the
-
doctors who treated their son, they had also
come up against the same compassionate fatalism
-
that proved so unpalatable to Ben Williams
and Richard Gerber.
-
I think that one argument that we used to
have with doctors when we talked about issues
-
like this is, they’d say… I’d say like
‘hey listen, throw the book at these kids,
-
it’s non toxic, get them in there, throw
cocktails at them and see how they do.’
-
Their argument back to me would be like well,
‘if some child survives we don’t know
-
why’, and I’d say ‘yeah, but that’s
a medical, scientific perspective. From a
-
parent perspective we don’t care why. He’s
alive and we’ll figure it out’. If we
-
keep doing it we’ll figure it out. We’ll
back door the answer. Somehow, someway, some
-
shape or form. The scientific community wants
to know why.
-
They believe in what they’re doing and,
know you, they want something that’s science
-
based. They want a clinical trial. They want
the proven results. That takes years to get
-
that kind of data, and these kids don’t
have that kind of time.
-
And you’d see the data, you’d see child
after child die and you’d have that mental
-
calculus going in your mind all the time because
you don’t want to harm your kid either because
-
the Hippocratic Oath is apparent: First do
no harm. It’s not about that…
-
Right, and so it’s not like you’re making
crazy, uneducated, you know, ‘we’re just
-
going to try anything’ decisions but…
-
You are absolutely right but like okay, but
I know this outcome. I don’t know what this
-
is going to be, but I know where this is going.
-
Given that the probability that the patient
is going to die is astronomical – it’s
-
almost 100% – what harm is there is adding
other ingredients to the therapy?
-
Why on earth would you possibly oppose it?
And the only answer to that is well, that’s
-
not part of the standard care and we’re
afraid that if you use anything other than
-
the standard of care that somehow we’ll
make things worse in a way that we don’t
-
understand. That’s not an acceptable position
in my view.
-
For the vast majority of patients, it is also
an unacceptable position. The advent of the
-
internet has seen a growing underground network
of patients and carers supporting each other.
-
This film is a direct result of such a community.
-
We had, you know, the whole community of neuroblastoma
parents who were medical doctors and things
-
themselves, and what we tried to do was read
the preclinical data, you know, and we were
-
just trying to stay ahead of the curve and
kind of predict where things were going to
-
go clinically. You know, you see a single
agent clinical trial and you know the data
-
for that or you talk to – it might not be
published data – but because we are neuroblastoma
-
community we know that 10 kids are on it and
they all progressed. There’d be publish,
-
preclinical data saying that ‘hey, the next
trial that’s going to come up is going to
-
be adding this second drug’, and so we would
get the second drug, and that was very common
-
place.
-
High profile survivors like Ben and Rich find
themselves inundated with requests for their
-
advice, and having experienced the despair
of falling outside the medical system themselves,
-
they can appreciate the desperation of patients
with no where to left to turn.
-
I’m an engineer, and many engineers carry
out risk benefit analysis naturally and routinely
-
in their work. In terms of the cocktails that
I had identified, I did my own independent
-
research, evaluated what the potential benefits
were compared to the side effects, and it
-
was quite clearly something that ought to
be tried. With the benefit of hindsight and
-
the reflection of where I am relative to the
prognosis, I am concerned that this approach
-
could not have taken place sooner. Many of
the doctors feel that they are not able to
-
engage in these off plan treatments, and perhaps
those that are outside the normal sphere of
-
training because they tend to feel that the
Hippocratic Oath limits their ability to do
-
that in the principle of ‘do no harm’.
But I believe that there are equally sins
-
of omission as there are
of commission.
-
There is no doubt that in the future we’re
going to be looking at multiple therapies.
-
The question that arises: doesn’t the patient
have the right to go an pursue combination
-
therapies and put them all together in a way
they think and their doctors hope will facilitate
-
a long term cure? The problem again comes
back to the issue of toxicity. Unless you
-
carefully study these combination therapies,
you may be doing more harm than good in many
-
cases, and although that there is clearly
the impetus to move forward with combination
-
therapies, they need to be studied.
-
However, for the reasons outlined in this
film, there is a distinct lack of clinical
-
trials investigating a cocktail approach to
cancer. Instead, it is normal practice to
-
expect patients to forgo curative treatment
in the hope that their sacrifice will someday
-
benefit someone else in their same position.
-
If you go to a major medical centre where
they are doing clinical trials, the trials
-
are not really a hundred percent intended
for the patient, they’d be intended for
-
a future patient, it’s intended for science
- or for a drug company - but, it’s intended
-
to find out more about the drug, it’s not
intended to cure the patient. Patients are
-
not aware of that. For science it is important
to study things singly because otherwise it’s
-
confounding. We cannot deal with multiple
unknown variables. You throw five drugs that
-
we don’t know much about t somebody and
they get better, we don’t really know what
-
happened. Which one of A, B, C, D, E did it?
We don’t know. You want to find out how
-
a drug works… that’s in scientific spirit.
That’s great for science, but there is some
-
conflict with clinical care which is with
a different intention: you want the patient
-
to get better.
-
When looked at closely, the history of cancer
tells its own story: In another era, when
-
doctors were more empowered to pursue patient
survival as a primary objective of clinical
-
care, dramatic progress was achieved in a
relatively short period of time. One such
-
doctor whose belief system is entirely geared
to patient outcome was a young haematologist
-
working at the newly formed National Cancer
Institute in the early 1960s. Emil J Freireich
-
was certain he had figured out a way to send
leukaemia into permanent remission. But he
-
faced enormous resistance for attempting to
combine highly toxic chemotherapy agents.
-
When I started treating leukaemia - I have
a slide of a quote from an article that was
-
written by a guy named Arthur Haut, who was
one of the senior physicians at the number
-
one haematology department in the world in
1955 when I went to the cancer institute.
-
The quote says… just what you said: giving
these drugs , 6MP, methotrexate, prednisone
-
to these children is just prolonging their
suffering, it has no effect on their survival.
-
And he was on our consultant (panel) and he
told our advisors that Freireich should no
-
be allowed to poison these dying children
–to let them die.
-
Undeterred by fierce resistance from his professional
community, Freireich questionably pushed ahead
-
with the assistance of some desperate parents,
and the rest is history. Today, a giant in
-
the field of oncology after blazing the trail
towards cure for childhood leukaemia, and
-
in the process inventing the platelet transfusion,
at the age of 87 Dr Emil J Freireich has half
-
a century of outstanding achievement in clinical
practice to reflect upon.
-
See I’m a devotee of the Hippocratic Oath.
That’s why it’s on my wall. Every physician
-
in the United States, and I think in England
and in Europe, who graduates from his medical
-
training swears by the Hippocratic Oath. Now
what’s the essence of the Hippocratic Oath?
-
Now what’s the essence of Hippocratic Oath
is that, as a physician, I will always do
-
whatever I can to help a person who is ill
and consults me.
-
For cancer patients staring death in the face,
the chilling realisation that despite a palliative
-
standard of care, they must wait for their
cancer to inevitably progress before their
-
doctors will engage with experimental treatments,
defies belief. In the vast majority of cases,
-
only then do experimental treatment options
become available to patients. We asked Dr
-
Freireich if in his opinion, this broke the
Hippocratic Oath…
-
It certainly does. Is there ever a circumstance
where a patient should be denied treatment
-
which could – in someone’s imagination
– help him survive his disease? And the
-
answer is no.
-
System Failure
-
Would the things we did in 1960 be possible
in today? The answer is, unequivocally, capital
-
‘N’, capital ‘O’ – NO!
-
By obliging doctors to follow rigid protocols,
our system for validating cancer treatments
-
is not only failing patients, but it is also
failing the innovators who are developing
-
treatments: a hidden consequence of forcing
patients to wait for cancer to reoccur before
-
giving them access to experimental treatments,
is that potentially promising treatments are
-
first tested only on these ‘recurrent’
patient populations, who already have genetically
-
mature cancer, and thus are far less likely
to respond to the drug or treatment than an
-
early stage patient. This means potentially
life-extending treatments for the newly diagnosed
-
are discarded forever because they cannot
show effect first on moribund patients.
-
Reforming regulations is the most important
thing we can do in advancing health in the
-
world. The AIDS patients told us how to solve
societal problems for specific diseases. See,
-
the AIDS guys were homosexuals and they were
used to being politically active and they
-
were organised, and when the FDA said you
have to do a randomised trial where you get
-
treatment you know won’t work and compare
it to treatment you think will work… they
-
said ‘hell no!’ and they marched on the
hill and they won. My personal view is that
-
that’s the way medical problems should be
solved. First we need the knowledge, then
-
we need the social solution.
-
ACT UP - the AIDS coalition to unleash power
- was a direct action group widely credited
-
with instigating the rapid acceleration of
AIDS research that transformed the once deadly
-
virus to a chronic condition in little over
a decade. Larry Kramer, New York City playwright
-
and author was a founding member, speaking
in the late 1980s as the AIDS pandemic gripped
-
the world in the face of institutional and
political indifference, his words echo violently
-
in the ears of cancer patients today: ‘placebo
studies were not designed with terminal illness
-
in mind’ he said and the ‘academic mechanism
of testing drugs is becoming life-threatening
-
rather than life-saving’, it’s ‘genocide
by neglect’ he claimed. As a result of ACT
-
UP’s unprecedented lobbying of congress
and the FDA, which included emptying urns
-
onto the white house lawn as per the will
of their members’, today’s life saving
-
treatment for AIDS is given to patient’s
despite it never having passed a randomised
-
phase three clinical trial: How many cancer
patients must die before the regulators recognise
-
this needs to be adapted to oncology in the
same fashion?
-
All they have to learn to do is balance benefits
against risks. If you have nine drugs that
-
are going to cure glioblastoma and you have
a patient that is 100% likely to die… lets
-
give them the nine drugs! Who’s against
that? You can’t do anything risk free. That
-
does not exist. You can’t walk across the
street without taking a chance. You can’t
-
wake up in the morning, you can’t eat food.
I mean, it’s nice to do as well as you can,
-
but you can’t be insane and we are insane
now. The regulatory process is insane. They
-
are trying to protect people. They inadvertently
get into a situation where they kill people…
-
but that’s not their intent. We’re just
human unfortunately.
-
For patients and carers, once these inefficiencies
come into focus, the incentive to adhere to
-
the rules of clinical trials evaporates along
with the validity of the precious data the
-
trial produces.
-
Do you want me to be totally honest? Yeah,
sure, neuroblastoma patients ship drugs. We’d
-
ship drugs by fed ex. We’d find clinical
trials and we’d be on a single agent and
-
we’d – other parents on the other trial
would send us their drugs and we’d send
-
our drugs. We had viruses from Israel that
other parents had given us that we’d tried
-
and… that’s what we did. There’s a whole
black market and grey market of drugs because
-
parents are so knowledgeable. I mean, there’s
Doctors, PHDs, MDs that have children with
-
neuroblastoma and it’s a very tight community
and they would do anything for anybody. In
-
fact, we, you know - that’s what we did
- created our own clinical trials for the
-
most part.
-
In randomised phase 3 trials, you have the
additional disincentive of placebo control
-
for half the patients. A quick glance at the
appalling enrolment rates around the world
-
and we can see that patient’s vote with
their feet.
-
It’s so obvious that if the FDA allowed
us to be rational about treating cancer patients,
-
we could move them all one hundred times faster.
As we did with AIDS, because what happened
-
was, the drug was good and the patients didn’t
have to die to prove it. And as you said in
-
the beginning ‘you need to do a randomised
phase 3 clinical trial’ No! if you have
-
phase two evidence that’s clear, if you
have an objective response, objective survival,
-
objective progression free survival, that’s
it… The truth is in itself. You don’t
-
have to do comparison, you have to have the
truth, you have to have reproducibility, you
-
have to have a lack of bias, and what you’ve
got there… that’s the answer man! The
-
AIDS guys did it. The cancer patients have
to do it. We have to force congress to change
-
legislation so that when a doctor and a patient
agree that the benefits succeed the potential
-
risk… that should go. Whatever way we make
it, that’s got to go.
-
New horizons
-
In all of the clinical trials to date, there
really hasn’t been much progress. Meanwhile,
-
those people however are dying. Yes, people
live a little bit longer with the standard
-
approach that we have now, but it’s not
much. And so, I would say this approach is
-
not working. It’s time to try something
else.
-
Traditionally, regulatory bodies have made
decisions that have been based on population
-
studies. So if you think about it for a moment…
We introduce a drug into a large population
-
in which we know there are many variables
in that population - people are different
-
– and we can’t control for those variables,
we don’t know what they are sometimes, we
-
just know they exist. So the way we dealt
with that in the past was to create this statistical
-
model of randomisation and, in fact, blinded
randomisation so we cover our eyes, and we
-
flip a coin, and we divide people up, and
we look for an outcome, and when we get an
-
outcome we put a statistical number on it,
and that gives us some assurance that yes,
-
that was really due to the drug and not something
else. Do we need that today? If I could go
-
into that population and I could - today - tell
you about those variables - which I couldn’t
-
before - because now I understand those genetic,
molecular make up of their individual cancer,
-
and I also under stand their genetic molecular
make up of them, as a person, and now I can
-
refine those populations. Do I still need
to put a blindfold on and flip a coin? Or
-
can I begin to be much more rational about
who I would treat with a particular drug and
-
who I would not. That is the adaptive trial
design. That is what cancer is teaching us
-
and telling us what we can now do, so we don’t
need to depend upon that old model. We can
-
be much more sophisticated, much more rational,
and we will get answers faster, we’ll be
-
much more certain that our answer is in fact
correct, and we will be able to allow patients
-
to have access to lifesaving drugs quicker,
faster, and with more assurance that they
-
are going to help them and not hurt them.
-
We accompanied Ben to University of California
Moore’s Cancer Centre to meet one of a new
-
generation of oncologists engaged in an ambitious
program of personalized medicine...
-
There’s two issues. One is, you know, what
are the best combinations for each particular
-
patient? Because, I think we all know that
glioblastoma is a different disease in every
-
single patient. If you took a hundred people
in a room there’s probably fifty diseases,
-
and so what we’re finding is that single
drugs seem to work better in some patients
-
than others because of the genetic make-up
of the tumour, and so when you talk about
-
combinations it’s even more complicated.
But we actually have a project where we’re
-
taking all the genetic information from each
patient, putting it into a computer, and coming
-
up with an answer to what drugs would be most
effective to each patient. So, it’s really
-
a personalised medicine approach to understanding
the genetics and using that information to
-
find the best combinations.
-
So as we move towards personalised medicine
where patients will receive combinations of
-
treatments, and that these combinations should
reflect the genetic characteristics of different
-
patients, then the only logical conclusion
to be drawn is that until we dismantle the
-
sanctity reserved for large-scale, randomised
phase III trials, we will never see meaningful
-
changes in patient survival.
-
Personalised medicine is the mantra. The irony
is that the practices up to now are directly
-
opposed to doing it. You can not – for most
of the randomised trials that are done, even
-
though you get a significant result – tell
an individual patient what the chances of
-
that treatment working for them will be. Right,
I mean, so, if you can’t do that, what you
-
started out… I mean the purpose of what
you started out to do - you’ve failed. You
-
need more homogeneous patients so that you
can actually say for this group of fairly
-
similar patients this particular treatment
will work. Well, you’re never going to do
-
randomised trials once you start thinking
in that framework of needing homogeneous patients.
-
Well if we don’t change the regulatory process,
what we’re already seeing is the biomedical
-
research enterprises collapsing. We’re seeing
investments beginning to dwindle because quite
-
frankly if you’re a venture capitalist or
an equity investor, you have far safer, quicker
-
opportunities for a return on investment than
to engage in hoping that a molecule - that
-
you’re going to be willing to fund very
early in it’s development – some how or
-
other is going to make its way through a 10-15
year process at the cost of over a billion
-
dollars to ultimately be able to give you
a return on that investment. So we’re seeing
-
negative consequences of not doing something,
and at the same time we also have the realisation
-
of the incredible opportunities if we would
do something and therefore, change has to
-
occur.
-
Acceleration
-
At the current rate of development of combination
therapy, testing combinations one by one,
-
it will take decades, and possibly centuries
to deliver more expansive cocktails to the
-
clinic. In the face of a clinical trial system
that is clearly failing, a new line of thought
-
is gaining traction in some oncology circles.
One man who is not hiding behind protocol,
-
is Marc Halatsch. He founded the International
Initiative for the Acceleration of Glioblastoma
-
Care as a framework to combine expertise and
engineer a treatment he feels will have a
-
better chance of combating cancer’s genetic
instability. This radical work involving untested
-
drug cocktails does not sit comfortably within
his scientific community, nor the pharmaceutical
-
companies Marc would normally enjoy sponsorship
from.
-
We have to (*) the protocol and that initially
involved 17 drugs. All of these drugs were
-
chosen to act in (*) against glioblastoma
to inhibit or suffocate signalling pathways
-
that are important for glioblastoma. We consciously
avoided to identify new targets for the glioblastoma
-
treatment. We were referring to drugs that
are approved are marketed for years for other
-
non-oncological indications and for which
a reasonable safety profile is already available.
-
So, the accelerated improvement means that
we are using drugs, that we want to use drugs
-
that are already available today, for which
we already have experience with human use
-
rather than identifying a new molecular target
and validating a candidate track for years
-
and years and then possibly finding out that
it doesn’t work. We have a rational basis
-
that these compounds are effective, that they
can be effective, and that they have reasonable
-
and justifiable risks even though we do not
know how these risks adapt when these substances
-
are combined.
-
During filming we were contacted by a senior
drug researcher for Glaxo-Smith-Klein in Cambridge
-
England, who had been diagnosed himself with
a high grade, inoperable brain tumour. He
-
refused to come on camera, even with his identity
hidden, but he was interested in Marc’s
-
paper, referring to the science behind it
as ‘beautiful’. But when he travelled
-
to a major centre for brain cancer in London,
in the hope of finding a forward thinking
-
clinician who might prescribe him the experimental
protocol, he was told the study was ‘unscientific’.
-
He died in 2014 leaving three young children.
-
Well if people say the paper is unscientific…
I think that it’s a judgement that cannot
-
be accepted because the paper is certainly
not unscientific. It is making a proposal
-
based on a set of hypothesis, and all of these
hypothesis are based on preclinical data,
-
on what we think is robust preclinical data.
What we can say for sure is that the recent
-
architecture of medical research for glioblastoma
patients has failed to bring out substantial
-
improvements for these patients and we don’t
know if you can do it better, but… we want
-
to try.
-
It is no coincidence that cancer cocktails
are first coming to light in the arena of
-
brain cancer. The limitations of surgical
intervention in the brain provide the impetus.
-
There’s a shift going on right now in a
lot of oncology where you may want to biopsy
-
a cancer, treat for four weeks with a mono
therapy (one drug), re-biopsy that cancer,
-
see if the genetics have changed, treat again
with a different drug for some period of time…
-
and so as the cancer shifts and mutates, you’re
changing your therapy accordingly.
-
If you don’t do that you may be treating
according to a profile that is simple outdated
-
because a tumour is a dynamic. The biological
situation may already have changed.
-
Now we can’t biopsy like that in the brain.
You can do that in the lung, the breast and
-
other answers… bone marrow. So we have to
figure out how’ll overcome those genetic
-
changes that will occur with treatment.
-
Well I believe, in the absence of bio-marker
profiles, it is very important to have a pragmatic
-
approach and to hit multiple targets at once
so that even if there is a change in the profile
-
and some pathways may compensate for other
inhibited pathways, you have a high chance
-
of maintaining a higher therapeutic pressure
against the tumour. In general, multi agent
-
protocol can be defended by pointing out the
heterogeneity of the tumour, and if you have
-
a set of drugs that act in concert then you
have a simple rule, and the rule is, the more
-
drugs you have the better you probably will
be able to address heterogeneity of the tumour.
-
This is an example of the new rational science
of treating cancer, based on the lessons that
-
cancer itself is teaching us. Yet what Marc
and his peers are pioneering, is in reality
-
revolutionary. The pharmaceutical companies
that own the drugs he is using have refused
-
financial support for his research, and he
is risking his professional reputation in
-
medical circles by even publishing this paper.
Cocktails are considered radical because if
-
such an ‘unscientific’ approach were to
work for patients, it would equate to opening
-
Pandora’s box, with the associated danger
of patients no longer being willing to accept
-
current medical practices. Few oncologists
would be willing to support such an investigation,
-
John Boockvar in New York, was an exception.
-
The idea of carpet bombing a cancer is an
appropriate idea where you just bombard the
-
tumour with multiple agents that will come
at it from different signalling pathways,
-
much like they do with HIV medicines, and
it will take that kind of approach to see
-
– I think – good outcomes. Of course our
delivery mechanisms, our ability to get these
-
drugs into tumours has to be better, our immune
systems in these patients has to be augmented,
-
improvement in immunotherapy will be an important
adjunct to any treatment, because if we cant
-
identify mutating cells or cells that are
distinct you have no chance… because chemotherapy
-
is only going to do so much without destroying
the natural body.
-
Never say die
-
Of all the patients we met during filming,
one man’s story stood out for his exceptional
-
courage and determination in the face of imminent
death. Anders Ferry is still fighting his
-
disease today, 15 years after being diagnosed
with terminal cancer at the age of 32. His
-
remarkable struggle for survival has encompassed
6 recurrences and 5 neurosurgeries including
-
some ground-breaking therapies and interventions.
Unable to travel alone, Anders and his father
-
Arne travelled to London at their own cost
from the far north of Sweden, to share his
-
story in this film.
-
Well I have been experimenting with my own
body and taking various odd combinations of
-
medications and non-mediations as well, under
very uncontrolled circumstances. So this has
-
been a marathon for me and for my wife in
particular. She has seen me through extremely
-
low points. The low points have been really
low, close to death.
-
Ander’s original course of chemotherapy
was stopped due to the development of a severe
-
rash, a result of sitting in a sauna trying
to raise his body temperature in order to
-
increase the efficacy of the chemotherapy,
Anders claims this rash released him from
-
a chemo educed mental-fog and afforded him
the clarity to do some preliminary research
-
online. He immediately enrolled on an innovative
American trial for an early immunological
-
compound. However, the compound was unapproved
in Europe at the time, so he had to smuggle
-
the drugs through customs as battery electrolytes.
-
So I was doing very well on that treatment,
but then after a couple of years they said
-
‘now we’re dropping the trial. Unfortunately
you won’t get anymore drug.’ And I panicked
-
of course. I thought, well this is what has
been keeping me alive for so long so I immediately
-
went into action to try to manufacture it
myself. As a physicist and physical chemist,
-
it wouldn’t be difficult for me to actually
create that molecule in the lab. So I pulled
-
all the patents and bought the chemicals,
borrowed lab resources, and my mother volunteered
-
to be my guinea pig to try it first before
I injected it myself.
-
At the eleventh hour, the founder of the drug
company, who had got wind of Anders’ desperate
-
attempt to stay on the medication, called
and insisted he did not use his own acetate,
-
instead sending him a life-time supply of
the drug the next day. By this time, it was
-
becoming clear to Anders that this was just
the beginning of his struggle, and that the
-
next challenge lay in combining different
treatments.
-
Well I got the idea to do several things simultaneously
when I read Ben Williams’ thoughts on it.
-
So I started adding little drugs that I could
access, gradually building up to a protocol
-
that involved many drugs in a big drug cocktail.
At its peak I was taking at least 8 prescription
-
drugs – off label… of course, they were
not chemotherapies, but assigned for entirely
-
different diagnosis – and lots of nutraceuticals.
The biggest obstacle to implement this protocol
-
has always been to actually find the prescription
drugs. They are available but you need somebody
-
to write the prescription, and I have been
lucky to have relatives and close friends
-
that could manage that for me. Sticking their
necks out. And occasionally my treating oncologist
-
has written out a few, but very reluctantly,
and has always been questioning ‘but why?
-
Is there any evidence for this?’ And I said
‘no, but there’s a potential in it.
-
Evidence is weak but there is some kind of hope.
Let’s try it, I’m willing.’ As the alternative
-
of doing nothing, you just look at the statistics…
every body dies within two years they said.
-
Well that’s not acceptable. By doing something
proactively, possibly ruining your health,
-
getting terrible side effects, but also possibly
getting real benefits, extending life. Like
-
I’m here now, a decade and a half later,
I’ve got two little kids, a happy wife,
-
a beautiful wife. My little Lynae and Tim
they are just my pride and joy of my life.
-
So, it has worked out well for me. Sure I
have deficits, but I can live with that. Life
-
with deficits is still life.
-
On three separate occasions, Anders has fought
back his cancer by combining conventional
-
surgery with innovative clinical trials, and
extensive, specifically tailored cocktails
-
of off-label drugs and nutraceuticals.
-
Well concerning the oncologists, I said ‘I’m
not really satisfied’ because when Anders
-
has his medication and it didn’t work and
the protocol didn’t work, they said ‘sorry
-
we can’t do anymore. You go home and play
with your girl’. I put the question, who
-
is responsible for their lives? Is it my son
who is supposed to take the care in his hand,
-
or is it so that the oncologist must have
some responsibility? He just can’t hide
-
behind the protocols.
-
Ander’s fight is one that is far from over,
and yet he too spends a great deal of his
-
time advising other patients, sharing whatever
knowledge or contacts he may have.
-
So ever since I created my internet persona
– Andrew Yassin – and hit the internet,
-
I’ve seen so many people come and go on
the lists. It’s terrible. Many people of
-
whom I’ve connected so strongly to, just
pass away. It’s dreadful.
-
Do you think that those patients were denied
something?
-
Absolutely, they were absolutely denied the
best care that could have been provided. I’m
-
sure many more would have been alive – or
at least had a much better chance to be alive
-
– if they had access to what I have been
doing for instance. I am also sure that this
-
approach could apply to other cancers, not
only brain tumours. I’ve seen effect in
-
advanced prostate cancers and breast cancers.
If I create a prescription of various off-label
-
drugs there is a viable option of prolonging
life for a long time, and that is also including
-
a creative and active life. I play my trumpet
at international jazz festivals. Perhaps not
-
at the same level as I could before having
all the surgeries, but still… it is a life
-
I enjoy and the kind I’m of proud of so
I’ve done well.
-
Reflections
-
Already facing a terminal diagnosis, should
cancer patients have to shoulder the additional
-
terror of unsupervised self-medication in
search of a meaningful attempt at survival?
-
None of the patients we spoke to wanted to
go it alone, they desperately wanted the reassurance
-
of professional medical supervision. Their
courage has showed us that the impossible
-
is sometimes possible, that there could be
a solution to problems we perceive as beyond
-
our reach.
-
I believe the medical community has an obligation
to do research into the cause – the clinical
-
cause of patients who have undertaken self-medications,
and who have reported extended life-span with
-
glioblastoma. I think it is an ethical obligation
of the medical community to try to understand
-
what happened with these patients, how they
did it, what their quality of life was and
-
how long they survived - these patients cannot
be ignored.
-
As survivors today, patients like Ben, Rich
and Anders stand as proof of principal. We
-
have the unprecedented opportunity to follow
this lead, employing the gifts that science
-
and technology are affording us to actively
embrace change. In the era of big data, Google,
-
and Apple, society can rationally ask the
medical establishment to reconsider its confidence
-
in a regulatory structure that served us well
in the past, but that appears slow, inefficient
-
and even inhumane in the context of terminal
disease today. The quid pro quo, that can
-
secure the continuation of a scientific methodology
and rational development of therapies, can
-
be the clinical data from EVERY patient. Retrospective
analysis of this data in the era of genomics,
-
can deliver the precious information we are
searching for in clinical trials, faster,
-
cheaper and more accurately.
-
Every professional I have ever talked to,
every oncologist, every neuro-oncologist,
-
every radio oncologist I’ve talked to, believes
that I am a freak chance, that my tumour would
-
have been put under control anyway, and that
my cocktail therapy didn’t contribute one
-
iota to it. They also think that Ben Williams
is a freak chance and that his 18 years would
-
have been given to him even without his experimentation,
and anybody that lives a long time – longer
-
than average - and uses a cocktail approach
is similarly dismissed as a freak chance.
-
But at a certain point, people are going to
have to start looking at the evidence.
-
Some will dismiss this evidence as merely
exceptions that prove the rule. But it is
-
hard to dismiss as coincidence Ben, Rich and
Anders’ shared academic background and scientific
-
training, unusual or illegal access to prescription
drugs, and the determination to overcome all
-
obstacles in the pursuit of their unorthodox
cancer therapies.
-
I’m quite sure that if I hadn't done what
I did I wouldn't be alive today. If I had
-
simply followed the prescription of my neuro-oncologist
I would have been just another statistic,
-
namely I would have lived another 12-18 months
and that would have been it. Because to my
-
knowledge he never had another long term survivor...

The Repurposing of Drugs in Oncology is an
initiative to provide oncologists with a robust,
-
independently researched database of old drugs
that could be helpful to combine with existing
-
standards of care across all cancers, enabling
them to prescribe off-label drugs with confidence
-
they will help and not hurt their patients.
-
With the support of a small charity in Belgium,
Marc Halatsch and Richard Kast’s CUSP9 cocktail
-
of drugs is in final stages of approval in
Germany for a phase 1 clinical trial for recurrent
-
glioblastoma. If the German regulatory authority
approve this trial in spring 2015 as anticipated,
-
they will set a global precedent for other
regulators to follow.
-
The film makers, together with the patients
and some of the doctors featured in this film,
-
are working with a UK charity to open an international
phase 1 clinical trial to investigate an expansive
-
cocktail approach for the newly diagnosed,
as an adjuvant therapy to the standard of
-
care for Glioblastoma. It remains to be seen
how such a proposal will be received by the
-
regulatory authorities across the world…
-
However, even if these trials go ahead, it
will take vast sums of money and many years
-
to ascertain if they hold benefit for patients.
Closing The Gap Now is an initiative to demonstrate
-
consensus within the scientific community
that patients with a prognosis of less than
-
24 months should be allowed access to any
treatment with phase 1 approval, in return
-
for donating their clinical data to an open-access
research database. The scientific community
-
would then be able to obtain certainty about
which treatments work for which patients much
-
faster, cheaper and more accurately than the
current system allows. www.closingthegapnow.org
