As Dr. Scher made clear in
his letter, his concern about Dendreon was not, strictly
speaking, that it didn’t work, but that it would render
irrelevant his work on Novacea’s competing treatment,
Asentar. A new phase 3 trial to test the effectiveness of Asentar
(referred to in the letter by its medical name, DN-101) had been
“designed, initiated and continues to accrue,” Dr.
Scher wrote. “I am the International Investigator on this
trial.”
Nowhere in his letter (and nowhere in the
conflict-of-interest waiver form that he submitted in order to
get a seat on the FDA advisory panel that voted on Dendreon’s
treatment) did Dr. Scher mention that he was not just the lead
investigator in the Asentar trials, but also a board member and
executive of Milken’s ProQuest Investments, which was, along
with affiliate Domain Associates, the biggest investor in Novacea,
the company that was developing Asentar.
Also left unmentioned was the fact that Dr. Scher was the
chairman of the “Therapeutic Consortium” of
Milken’s Prostate Cancer Foundation. The “Therapeutic
Consortium” helps Milken’s “philanthropic”
outfit decide which treatments and hospitals deserve its
support. It is clear that the Prostate Cancer
Foundation’s donations to hospitals such as Dr. Scher’s
Memorial Sloan are linked to the hospitals’ support of
specific treatments being developed by specific Milken-affiliated
companies.
For example, in one typical press release, the Prostate Cancer
Foundation stated that the “Therapeutic Clinical
Investigation Consortium [the Milken Prostate Cancer Foundation
outfit of which Dr. Scher is the chairman] played an important role
by accelerating testing of this new agent [Abiraterone, the agent
developed by Milken crony Lindsay Rosenwald’s Cougar
Biotechnology] in Phase II clinical trials…Right now, at MD
Anderson and Memorial Sloan-Kettering, both NCI funded cancer
centers, the Phase III trials of Abiraterone [Cougar’s
treatment] are going on. PCF contributions to Sloan-Kettering
reached $18 million to date, possibly more…”
In other words, Milken raised money from unsuspecting donors,
including the ordinary folks who slipped cash into the buckets that
the Prostate Cancer Foundation places outside of supermarkets and
shopping malls. Then Milken, with the support of Dr. Scher,
directed that money to Dr. Scher’s hospital, with the
understanding that Scher and his hospital would attach their
prominent names to drugs developed by companies in which either
Milken or Milken’s friends were investors.
Keep in mind that the prostate cancer drugs developed by
Milken-affiliated companies were in the earliest stages of
development – there was not yet much evidence that they could
help patients. But, as we will see, there was lots of potential for
them to make money for Milken and his friends.
Meanwhile, the Prostate Cancer Foundation and affiliated doctors
diverted attention, or (in the case of Dr. Scher) attacked
Dendreon, the only company with a new treatment for prostate cancer
that could be delivered to patients right away, and for which
“substantial evidence” existed that showed it
worked.
This is not exactly
“philanthropy” in its purest form.
* * * * * * * *
Remember, on March 29, 2007, when Dr. Scher sat on the
FDA’s advisory panel, he was one of the 17 doctors who voted
unanimously that Dendreon’s treatment was safe. And two weeks
later Dr. Scher wrote a letter to the FDA in which he vigorously
trashed Dendreon’s treatment.
As mentioned, this letter was strange in that it was
unprecedented for an FDA-contracted doctor to lobby the FDA after
an advisory panel had already voted. It was strange in that the
presumably confidential letter was quickly published by The Cancer
Letter, an outfit with a reputation for being an organ of short
selling hedge funds. And the letter was strange in that it was
disingenuous, to the say the least.
For one, Dr. Scher seemed to have changed his mind with regards
to the safety of Dendreon’s treatment.
In his letter to the FDA, he noted that the advisory panel had
discussed the fact that Dendreon’s trials showed that 4.9% of
patients treated with Provenge had experienced
“cerebrovascular events” compared to 1.7% of patients
who were given a placebo.
The panel’s 17 doctors, Scher included, had voted
unanimously that this was an acceptable risk for patients with a
deadly disease – especially since, in other regards, Provenge
appeared to be perfectly safe. But now Scher was insisting in
a letter to the FDA that these rare “cerebrovascular
events” (few of which were fatal) were worrisome enough to
deprive end-stage prostate cancer patients of a treatment that
might extend their lives.
But Dr. Scher’s “cerebrovascular events”
argument was not new. It was precisely the same canard that had
been delivered to the press by those dubious Wall Street players
— the singing Sendek, and doctor-impersonating Aschoff, the
troubled UBS, and the whispering hedge fund managers.
As to the effectiveness of Provenge, Dr. Scher averred in his
letter that Dendreon had not met its “primary
end-points” and the data was “not considered
definitive.” He insisted that the treatment be delayed until
Dendreon could provide “proof” that Provenge extended
lives.
This was absurd. As Dr. Scher must have known, rarely in history
has data on an experimental treatment shown definitive
“proof” that the treatment works in every case.
Instead, the legally established criteria for FDA approval
(especially of treatments for life-threatening diseases) is that
the data show “substantial evidence” that the treatment
improves the health of patients. Neither medicine nor science
progresses by “definitive proof”.
Even if trials do not meet their “primary
end-points,” the FDA usually approves treatments for deadly
diseases if the odds are nonetheless good that the treatments
increase survival. The odds might not be 100 percent, but if they
are 98 percent, or even 51% percent, the treatment should be
delivered to patients who will otherwise die. This criteria –
“substantial evidence” of increased patient survival
– is referred to as “the Gold Standard” by FDA
officials and doctors everywhere.
In any case, “it may be time we focus less on statistical
significance, and more on patient benefit.” So said Dr. Scher
himself, in an interview
with a medical journal, just a few weeks before he wrote a letter
to the FDA harping on Dendreon’s statistical significance.
Most likely, Dr. Scher was thinking about his trials of Asentar
(the drug under development by Novacea, which was controlled by
Milken’s ProQuest Investments and an affiliate) and
Abiraterone (the drug developed by Milken crony Lindsay
Rosenwald’s Cougar Biotechnology). These trials had not
yielded particularly good results.
In fact, as we will see, Asentar was not just unhelpful to
patients. During trials of the treatment, patients dropped dead.
They dropped dead earlier than expected. And, as Novacea
later acknowledged, the cause was clear: Asentar actually
killed a significant number of people who were hoped to
benefit from it. Provenge increased “cerebrovascular
events” in a small number of patients, but patients on
Asentar died in such large numbers that Novacea had to discontinue
its trials of the drug.
The question is: Did Milken’s
Prostate Cancer Foundation, Dr. Scher, and the Wall Street hedge
funds really believe that competing treatments were superior to
Provenge when they began their attack on Dendreon? Or were
their attacks motivated by their financial interests?
* * * * * * * *
It was not necessary for Asentar to receive FDA approval in
order for Milken’s ProQuest to make heaps of money from its
investment in Novacea. As we will see, the Milken clan had hatched
a plan to cash in on their Novacea stock, regardless of what the
FDA had to say about the company’s prostate cancer treatment,
and regardless of whether that treatment would eventually be shown
to kill an unacceptable number of people.
Same goes for Cougar Biotechnology’s investors, who
included not just controlling shareholder Lindsay Rosenwald (who
once helped run the Mafia-affiliated D.H. Blair, which was indicted
on 173 counts of securities fraud and was famous for pumping phony
biotech companies), but also two of the seven Milken network hedge
funds that were betting big against Dendreon. Cougar’s
treatment, supported by Milken’s philanthropy and by the four
Prostate Cancer Foundation doctors who sat on Cougar’s
advisory board, was virtually untested, but as we will see, this
did not prevent the company’s investors from cashing in.
When Dendreon came under attack, similar plans to cash in had
been hatched by investors in a company called Cell Genesys, whose
experimental (and, we will see, ineffective) treatment was promoted
in a most peculiar fashion (which I will describe in due course) by
Milken’s Prostate Cancer Foundation.
Investors in those companies did not need FDA approval to make
money, but as we will see, their money-making plans would have been
foiled if Dendreon had received approval. In reading
the transcript of the FDA advisory panel meeting that voted on
Provenge in March 2007, one has to wonder if Dr.
Scher—who led trials for not only Novacea and Cougar, but
also Cell Genesys–knew of these money-making plans, and if
this knowledge informed the lobbying he undertook at the panel
meeting, and in the days following it.
Among Dr. Scher’s more revealing statements at the
advisory panel meeting was this: “So if I start thinking, am
I denying a potentially useful agent [Dendreon’s Provenge] to
men who clearly need it, the answer is unfortunately I don’t
know. So I say, well, what if we think that this really should be
available, start thinking about the number of agents that are
currently under development.”
This is the same message that was whispered in the ears of
reporters, who eagerly transcribed it into their stories. If the
FDA approved Provenge, they said, it would become the standard of
care. This would be unfortunate because other treatments
“under development” might be better. The problem with
this argument is that there were very few other treatments
“under development.” And when Dr. Scher referred to
treatments “under development,” there was little else
he could have been referring to other than the above-mentioned
Asentar (Novacea), Abiraterone (Cougar Biotechnology), and GVAX
(Cell Genesys).
As mentioned, Dr. Scher was connected to all three of those
companies. Novacea’s Asentar, we know, was killing people. At
the time of Dr. Scher’s attack on Dendreon, Cougar’s
Abiraterone had been tested on a total of 38 patients. The data
showed that some of those 38 patients saw their blood tests
improve, and Cougar Biotechnology trumpeted this
information in multiple press releases, but there was zero
evidence that Abiraterone increased patient survival. GVAX
<
had been testedBut Dr. Scher was insistent – ”a
number of alternatives [those "alternatives" being drugs under
development by Milken and his cronies with the assistance of Dr.
Scher and Milken’s ‘philanthropy’, drugs that
would prove, in time, to be inferior] were “currently under
development.” And so patients must not have access to
Dendreon’s drug – a drug that was capable of
saving lives right away.
* * * * * * * *
To understand the lengths to which some people went to derail
Dendreon, it is necessary to recall the Dendreon conference call,
when the singing-Sendek kept asking whether the FDA might have to
“change the question.” Others on Wall Street were
whispering about “the question,” the press transcribed
into their stories these same whisperings about “the
question,” and Dr. Scher made “the
question” a key feature of his letter to the FDA. All of them
suggested that the FDA advisory panel vote was invalid because the
13 panelists who had voted that Provenge worked had, in fact, voted
on the “wrong question.”
The
transcript of the Dendreon advisory panel meeting clarifies
what was meant by all of this questioning of the
“question”. As noted, advisory panels are always asked
to vote on two questions: Is the treatment safe? And, is there
“substantial evidence” that the treatment is
effective?
This is not just custom. It is the law of the land. The 1962
Kefauver Harris Drug Amendments, ratified by the U.S. Congress,
stipulated that manufacturers of drug products must establish a
drug’s effectiveness by “substantial
evidence.”
On the first question, “Is the treatment safe?” the
advisory panel had voted “yes”, 17-0. Those 17 included
Dr. Scher (though, as has been explained, within weeks he was
lobbying the FDA by raising doubts as to the safety of
Provenge).
The second question to be addressed was, therefore, “Is
there substantial evidence that the treatment is effective?”
Dendreon had clearly met this standard – the “Gold
Standard” of providing “substantial evidence” of
increased survival.
But remarkably, somebody at the FDA advisory panel meeting
rewrote the “question.” The chairman of the panel read
the question out loud: “Does the submitted data establish the
efficacy of [Provenge] in the intended population?”
Immediately, there was confusion. This was not the usual
question. Did “establish the efficacy” mean that the
panelists had to vote on whether the data had proved, with 100%
conclusiveness, that Provenge extended lives? No experimental drug
had ever faced such a standard.
Dr. Scher interjected to say that Dendreon’s trials had
failed to meet their “two primary end-points.” To this,
the FDA’s representative on the panel, Cecilia Witten,
remarked that the FDA was aware that the trials failed to meet its
two primary endpoints, but that was not the issue. The issue was
whether the evidence suggested that Dendreon’s treatment
saved lives.
“You know,” Witten said. “We’re given
the application based on survival.”
The chairman of the panel resumed with the same question.
“Again I’ll read it,” he said. “Does the
submitted data establish the efficacy…?”
Thus began the voting. Dr. Scher quickly voted,
“No.” So did another physician, Dr. Maha Hussain, and
two other doctors. But confusion reigned.
One panelist, a certain Dr. Alexander, said, “So
that’s – so my vote is, I don’t know what you
would call that…”
A Dr. Chamberlain said, “Well, so I guess at this point
I’m not sure how to answer this question. It’s not a
yes or no question in my opinion the way it’s phrased. With
the safety data and with what we’ve seen, I see no reason not
to make this drug available, but I don’t think it’s 100
percent proven that it’s efficacious.”
A Dr. Chappell said, “There’s a degree of belief,
and ‘establish’ implies much more certainty…you
need please, to specify, at least to me, what you mean.”
A Dr. Alexander piped in, “Like is it a reasonable doubt,
a shadow of a doubt?”
At this, there was a lot of mumbling and some laughter. Finally,
the FDA’s representative clarified. “Yes,” she
said, “the regulatory definition is ‘provide
substantial evidence.’ So that’s our standard. Is there
substantial evidence that it works…”
The chairman of the committee responded, “So just to
clarify what you’re asking, is there substantial
evidence that the product is efficacious?”
“Yes,” said the FDA’s representative.
That resolved any doubts, and 13 of
the 17 doctors on the panel confidently voted
“Yes.” That is to say, when the doctors voted on
the correct question – the question that was stipulated by
law, as opposed to the question that had been tampered with —
the overwhelming consensus was that Dendreon’s treatment
should be approved.
