Public ‘misled’ by drug trial claims

Doctors and patients are being misled about the effectiveness of some drugs because negative trial results are not published, experts have warned.

Writing in the British Medical Journal, they say that pharmaceutical companies should be forced to publish all data, not just positive findings.

The German team give the example of the antidepressant reboxetine, saying publications have failed to show the drug in a true light.

Pfizer maintains its drug is effective.    Reboxetine (Edronax), made by Pfizer, is used in many European countries, including the UK.

But its rejection by US drug regulators raised doubts about its effectiveness, and led some to hunt for missing data.  This is not the first time a large drug company

has come under fire about its published drug trial data.

Trial information

Pharmaceutical giant GlaxoSmithKline (GSK) was criticised for failing to raise the alarm on the risk of suicidal behaviour associated with its antidepressant Seroxat.

GSK rejected claims that it improperly withheld drug trial information.

But GSK has also been forced to defend itself over allegations about hiding negative data regarding another of its drugs, Avandia, which is used to treat diabetes.

Now researchers from The German Institute for Quality and Efficiency in Health Care say there is unpublished trial data for Pfizer’s antidepressant reboxetine that should be made public because it could change views about the drug.

Dr Beate Wieseler and colleagues carried out their own assessment of reboxetine, looking at the results of 13 trials, including eight previously unpublished trials from the manufacturer Pfizer.

They found the drug was no better than a placebo in terms of remission and response rates. And its benefit was inferior when compared with other similar antidepressants.

Furthermore, a higher rate of patients had side effects with reboxetine than with placebo. And more stopped taking the drug because of side effects compared with those taking a placebo or a different antidepressant.

Biased picture

The researchers said there has been a publication bias and this had overestimated the benefit of reboxetine and underestimated potential harm. And, they said, it was a widespread problem that applied to many of the drugs in use today.

“Our findings underline the urgent need for mandatory publication of trial data,” they say in the BMJ.

They warn that the lack of all information means policy makers are unable to make informed decisions.

Drug Firms Face Bribery Probe from US Department of Justice

Justice Department, SEC Seek Information From Companies on Payments to Overseas Officials

Wall Street Journal, October 5, 2010

by Michael Rothfeld

Federal investigators are looking at ways that drug makers could be paying bribes overseas to boost sales and speed approvals, according to letters sent to the companies and people close to the matter.

Big companies—including Merck & Co., AstraZeneca PLC, Bristol-Myers Squibb Co. and GlaxoSmithKline PLC—in recent months have disclosed they are being investigated for possible violations of a 1977 law that makes it illegal for companies whose stock is traded in the U.S. to bribe government officials in other countries to get business.

[PHARMA]

The companies said they are cooperating with the government, with several adding that the investigation is industry-wide and broader than their companies specifically. Many said they have policies meant to ensure compliance with the Foreign Corrupt Practices Act.

So far, none of the companies has been accused of wrongdoing, and the investigation ultimately may not result in charges.

The Justice Department and the Securities and Exchange Commission requested that companies voluntarily report any violations of the FCPA. Some companies, including SciClone Pharmaceuticals Inc. and Eli Lilly & Co., disclosed receiving subpoenas from the SEC. Baxter International Inc. also has said it is being investigated.

The investigation is targeting transactions in Brazil, China, Germany, Italy, Poland, Russia and Saudi Arabia, people familiar with the matter said.

The Justice Department and the SEC declined to comment.

Such requests from the government typically kick off internal investigations at companies, which generally comply with the requests in order to win leniency from the government if a violation is found.

A lawyer for one drug company said the industry has been vexed because the recent requests were so broad and because the investigations, across operations in several countries, can cost millions of dollars.

“If you don’t have any specifics, a lot of this is just guesswork,” the lawyer said. “Everyone was running around to get in the door to meet with the government so they can better understand what the issues are.”

Letters from the government to one of the companies, which were reviewed by The Wall Street Journal, identified four types of possible violations: bribing government-employed doctors to purchase drugs; paying company sales agents commissions that are passed along to government doctors; paying hospital committees to approve drug purchases; and paying regulators to win drug approvals.

People familiar with the situation said the other companies received similar letters.

The requests are similar to the government’s actions in an older bribery probe involving medical devices. In that investigation, settlement talks are ongoing with several companies, according to a person familiar with the matter.

Representatives for Merck, AstraZeneca, Bristol-Myers, Glaxo and Baxter declined to comment on the probe beyond saying they were cooperating fully with the government.

A SciClone spokeswoman declined to comment beyond the company’s SEC filings, in which it said it was subpoenaed for documents relating to its practices in China. A Lilly spokesman referred to an SEC filing in which the company said the U.S. government expanded to other countries an investigation of its Polish subsidiaries that began in 2003.

U.S. officials and European regulators have become increasingly aggressive in investigating foreign bribery cases in recent years. U.S. officials recently have threatened to file charges against executives and not just their companies.

The pharmaceutical industry is particularly vulnerable because government plays a bigger role in administering medicine in many foreign countries than it does in the U.S. and drugs are highly regulated, which creates contact with public officials. Doctors and hospital administrators often are government employees overseas.

Some of the alleged bribes could involve payments to doctors to influence drug trials, people familiar with the situation said. Justice Department officials have said publicly that drug companies also could face charges if they bribe government officials in the guise of payment for travel, meals, entertainment or speaking fees.

Professor of Bioethics—Co-opted by market forces, clinical drug trials are now just covert instruments for promoting drugs

Friday, August 20th, 2010

MinnPost.com

By Susan Perry |

In the September issue of Mother Jones magazine, Dr. Carl Elliott, a professor of bioethics at the University of Minnesota, writes about the suicide in 2004 of 26-year-old Dan Markingson, who was enrolled at the time in a U of M industry-funded clinical trial of the antipsychotic drug Seroquel (quetiapine).

It’s a disturbing tale (the unsuccessful efforts of Markingson’s mother to get her son released from the trial and into other treatment are particularly heartbreaking) and one that, as Elliott acknowledges, was first told in the Pioneer Press by Jeremy Olson and Paul Tosto.

But Elliott’s purpose in writing the article wasn’t only to revisit the tragic details of Markingson’s story. “[T]he more I examined the medical and court records, the more I became convinced that the problem was worse than the Pioneer Press had reported,” he writes. “The danger lies not just in the particular circumstances that led to Dan’s death, but in a system of clinical research that has been thoroughly co-opted by market forces, so that many studies have become little more than covert instruments for promoting drugs. The study in which Dan died starkly illustrates the hazards of market-driven research and the inadequacy of our current oversight system to detect them.”

Those hazards include questionable informed consent (is a young man who’s experiencing psychotic episodes competent to give his consent?) and financial conflicts of interest. According to Elliott, the U of M psychiatry department earned $15,648 for each person it enrolled in the Seroquel study. In addition, the study’s two U of M investigators, Drs. Charles S. Schulz and Stephen C. Olson, personally earned a combined $811,045 between 2002 and 2008 from Big Pharma, including $261,364 from AstraZeneca, the maker of Seroquel.

At the time Markingson entered the Seroquel study, reports Elliott, the investigators were having serious problems recruiting subjects. Did that factor lead them to enroll someone into the study who shouldn’t have been?

“Even by the standards of a fairly ugly history [of clinical drug trials with ethical breaches] in medical history — even by those standards, this [case] jumps up,” Elliott told me in an interview last week. “There were so many things that went wrong — the consent process, the commitment order under which [Markingson] was recruited into the trial, the financial incentives of the university, the financial incentives of the investigators, and the sheer worthlessness of the trial. Anyone who looked into this and knew anything about clinical research would say this is terrible.”

Elliott sees the trial’s worthlessness as a particularly abhorrent part of the story. The Seroquel study was designed as a marketing tool, he suggests, not as a true scientific inquiry. Such studies, he writes, present a huge ethical problem that isn’t being properly addressed by the oversight systems currently in place:

What is simply assumed [when bioethicists and regulators debate the risks of a clinical trial], without much consideration at all, is that the research is being conducted to produce scientific knowledge. This assumption is codified in a number of foundational ethics documents, such as the Nuremberg Code, which was instituted following Nazi experiments on concentration camp victims. … But what if a research study is not really aimed at producing genuine scientific knowledge at all? The documents emerging in litigation [involving various prescription drugs] suggest that pharmaceutical companies are designing, analyzing, and publishing trials primarily as a way of positioning their drugs in the marketplace. This raises a question unconsidered in any current code of research ethics. How much risk to human subjects is justified in a study whose principal aim is to “generative commercially attractive messages”?

Or, as Elliott told me: “I don’t think anybody who enrolls in a clinical trial thinks, “I know this study is risky, but I think it’s worth it to help Pfizer or AstraZeneca market their drug.”

Psychiatrist pleads guilty to 15 counts of fraud in Paxil clinical trials for kids

Friday, August 20th, 2010

CNBC

Associated Press

NEW ORLEANS – A 58-year-old psychiatrist involved in two clinical trials evaluating the drug Paxil’s safety and effectiveness in children and adolescents has pleaded guilty to 15 federal counts of failing to prepare and maintain records, with intent to defraud and mislead, in connection with those clinical trials.

Dr. Maria Carmen Palazzo was a clinical investigator for SmithKline Beecham doing business as GlaxoSmithKline. Prosecutors say that during those studies she included psychiatric diagnoses inconsistent with patients’ psychiatric histories; prepared multiple psychiatric evaluations on study patients which contained different diagnoses and reported symptoms she knew the study subject did not demonstrate.
