Pfizer, makers of Zoloft and Viagra cannot seem to stay out of trouble
lately. This is one of several messes they have found themselves caught in
around the world lately. I thought all of you who barely survived your bouts
with Zoloft would be interested.
Not that Pfizer is the only drug company out there doing this type of thing.
They just got caught. I have learned over the last decade of doing research
on these issues that most drug companies would not blink an eye in deciding
to do the same. They are so often caught in such underhanded dealings that I
wonder why they are allowed to continue business.

Doctors Say Drug Trial’s Approval was Backdated

The Nigerian doctor who supervised a 1996 Pfizer Inc. drug experiment on
desperately ill children said in an interview that his office created a
backdated ethics approval document that the American pharmaceutical company
later used to satisfy U.S. regulators and to justify its conduct of the
Abdulhamid Isa Dutse, the physician who oversaw the test of the antibiotic
Trovan on children with meningitis, said the letter may have been written as
long as a year after the test was completed when Pfizer officials asked him
for proof the test was reviewed by a Nigerian ethics board. Nigerian
officials are now examining the roles played by Dutse and others in
conducting the American company’s drug trial, which was the subject of an
investigation by The Washington Post.
Pfizer spokesman Andy McCormick said last week that he was unaware of
possible irregularities in the Nigerian ethics approval document. “We are
currently investigating it. We are cooperating with the authorities in
Nigeria,” he said.
The New York-based company gave the letter to the U.S. Food and Drug
Administration in 1997 during an audit of records supporting its application
to use Trovan for treatment of children during a meningitis epidemic. U.S.
regulations require that if a company intends to use foreign medical
research to support a drug application, the experiments must be reviewed and
formally approved in advance by an ethics committee.
FDA officials last week declined to comment on the Pfizer case, but one
official said it is a violation of federal law to knowingly submit false
documents to a government regulatory agency.
Typed on the letterhead of the Aminu Kano Teaching Hospital and dated March
28, 1996 — six days before Pfizer’s experiment began — the letter said the
hospital ethics committee had reviewed the plan to test Trovan on 100
children with meningitis and found the protocol to be “adequate.” The letter
gave permission for the test to proceed.
But Sadiq S. Wali, the hospital’s medical director, recently told The
Washington Post the document was “a lie.” He said the hospital had no ethics
committee at the time Pfizer’s test was underway and did not organize it —
or create the letterhead stationery bearing his name that was used in the
approval letter — until months later.
“The hospital is quite clear: We had no ethical committee,” he said in a
Reached by telephone in Kano last week, Dutse said it was “possible” that
the approval letter was drafted up to a year after the trial.
Dutse, who was listed as Pfizer’s “principal investigator,” said he felt
that the letter reflected the informal approval he had obtained from three
doctors, who reviewed Pfizer’s test plans and told him they saw no ethical
problems. No records were prepared at the time, he said.
But one of the doctors Dutse cited, Idris Mohammed, last week disputed
Dutse’s account. Reached in London, Mohammed said: “There was no ethical
committee at the time of the trial, none met, and no approval was properly
given for the trial.”
In fact, Mohammed said that he challenged the legality of Pfizer’s
experiment while it was underway and that he demanded unsuccessfully to see
documents proving it had been properly authorized.
“You shouldn’t try an experiment in an epidemic,” said Mohammed, a medical
professor who now heads the Nigerian federal immunization program. “You
needed to give these patients something that was proven.”
Mohammed said that in 1996 he took his concerns to a senior official in the
Nigerian government — then controlled by a military dictator, Gen. Sani
Abacha — but was overruled.
Since the experiment, Pfizer repeatedly has cited the Nigerian committee’s
approval as proof its experiment was ethical. The testing was carried out on
children and infants during a record-breaking meningitis epidemic that
killed more than 15,000 Africans.
The Post’s Dec. 17 article recounted how Pfizer physicians tested the
company’s then-unapproved antibiotic in the impoverished northern Nigerian
state of Kano. The drug was later associated with liver damage and deaths in
the United States and its use was restricted.
Pfizer described the Nigerian test as a humanitarian venture, but medical
specialists and international aid workers attacked it as unethical and
challenged the company’s claim that the children knew they were part of an
Pfizer officials have said that the Nigerian ethics committee approved
giving some Nigerian children an oral formulation of the antibiotic instead
of a fast-acting intravenous version used in U.S. meningitis tests.
A Pfizer spokeswoman also said the ethics committee decided there was no
need to warn Nigerian parents that young lab animals given Trovan-class
antibiotics had suffered joint damage. American parents were told of the lab
animal results in a subsequent Trovan trial.
After receiving a copy of the ethics approval letter from The Post, Wali
said he confronted Dutse and the doctor “did admit to me he was wrong,”
although he provided few specifics.
Tim Menakaya, Nigeria’s health minister, said he had appointed a federal
investigative panel charged with determining whether the trial was conducted
legally and, if so, whether the experiment was “morally right.”
“I am investigating all of it,” Menakaya said.
The probe is headed by Abdulsalami Nasidi, a senior health official who said
that he, like Mohammed, considered the experiment to have been unethical in
1996 but failed in attempts to block it.
“It is a very serious problem; procedures were not followed,” Nasidi said.
“We are going to get to the root of the problem.”
Nasidi said that his investigation, whose findings will be forwarded to
Nigerian President Olusegun Obasanjo, failed in initial attempts to locate
“detailed evidence” that Pfizer’s investigators had secured the needed
authorization before launching the experiment. Dutse said he spent two days
last week addressing a closed session of the panel.
The Post’s investigation has generated a flurry of stories in the Nigerian
press, which have reported that “widespread condemnation rages.” Editorials
have called for international investigations, federal lawsuits and criminal
Nigerian newspapers — always fiery and at times less than entirely
factual — have quoted parents who contend their children had serious
disabilities or died after treatment.
“The government has a duty to tell us whether our children were used as
guinea pigs and, if so, who committed such criminality and who is liable,”
said the Vanguard newspaper.

Pfizer accused of irregularities during clinical trial in Nigeria
Sarah Boseley, health editor
Wednesday January 17, 2001
An inquiry is under way in Nigeria into allegations that the multinational
pharmaceuticals company Pfizer used an experimental drug on sick children
during a major outbreak of meningitis, without official approval.
Yesterday the Nigerian doctor employed by Pfizer to run the clinical trial
in Kano said that the letter certifying approval by the ethics committee at
the hospital where the children were treated was probably written a year
after the experiment took place.
Pfizer admitted last night that there did “appear to be possible documentary
irregularities” and said they were co-operating fully with the inquiry.
Pfizer sent a team in to Kano at very short notice in 1996, when it heard of
the outbreak of spinal meningitis. The company wanted to test the efficacy
of its new drug Trovan on children, and such outbreaks in the west are now
