FDA Scientist Complain to Obama about FDA corruption

FDA scientists complain to Obama of 'corruption'
By RICARDO ALONSO-ZALDIVAR, Associated Press Writer Ricardo Alonso-zaldivar, Associated Press Writer Thu Jan 8, 6:22 pm ET

WASHINGTON – In an unusually blunt letter, a group of federal scientists is complaining to the Obama transition team of widespread managerial misconduct in a division of the Food and Drug Administration.

"The purpose of this letter is to inform you that the scientific review process for medical devices at the FDA has been corrupted and distorted by current FDA managers, thereby placing the American people at risk," said the letter, dated Wednesday and written on the agency's Center for Devices and Radiological Health letterhead.

The center is responsible for medical devices ranging from stents and breast implants to MRIs and other imaging machinery. The concerns of the nine scientists who wrote to the transition team echo some of the complaints from the FDA's drug review division a few years ago during the safety debacle involving the painkiller Vioxx.

The FDA declined to publicly respond to the letter, but said it is working to address the concerns.

In their letter the FDA dissidents alleged that agency managers use intimidation to squelch scientific debate, leading to the approval of medical devices whose effectiveness is questionable and which may not be entirely safe.

"Managers with incompatible, discordant and irrelevant scientific and clinical expertise in devices...have ignored serious safety and effectiveness concerns of FDA experts," the letter said. "Managers have ordered, intimidated and coerced FDA experts to modify scientific evaluations, conclusions and recommendations in violation of the laws, rules and regulations, and to accept clinical and technical data that is not scientifically valid."

A copy of the letter, with the names of the scientists redacted, was provided to The Associated Press by a congressional official.

"Currently, there is an atmosphere at FDA in which the honest employee fears the dishonest employee, and not the other way around," the scientists wrote.

FDA spokeswoman Judy Leon said in response: "We have been working very closely with members of the transition team and any concerns or questions they have on any issue, we will address directly with the team. Separately, the agency is actively engaged in a process to explore the staff members' concerns and take appropriate action."

Senior Democratic and Republican lawmakers are urging Obama to appoint a commissioner who will shake up the FDA and restore the confidence of its working-level scientists and medical experts. But industry officials fear that approval of new drugs and devices could be delayed by endless scientific disputes — which is the agency's reputation.

The FDA dissidents have previously taken their concerns to Congress and found support from lawmakers in the House.

In the letter the group singled out mammography computer-aided detection devices as an example of a technology that should not have gone forward. The devices were supposed to improve breast cancer detection, but instead studies showed they were associated with false alarms that led to unnecessary breast biopsies.

Since 2006, FDA experts have recommended five times against approving the devices without better clinical evidence, the letter said. In March of last year, a panel of outside advisers supported some of the concerns of the FDA's in-house scientists. Nonetheless, FDA managers overruled the objections and ordered approval.

Top FDA managers "committed the most outrageous misconduct by ordering, coercing and intimidating FDA physicians and scientists to recommend approval, and then retaliating when the physicians and scientists refused to go along," the letter said.

A spokeswoman said the Obama transition team had no comment.

The Politics of Marketing Gardasil

August 20, 2008
The Evidence Gap
Drug Makers' Push Leads to Cancer Vaccines' Rise
By ELISABETH ROSENTHAL

In two years, cervical cancer has gone from obscure killer confined mostly to poor nations to the West's disease of the moment.

Tens of millions of girls and young women have been vaccinated against the disease in the United States and Europe in the two years since two vaccines were given government approval in many countries and, often, recommended for universal use among females ages 11 to 26.

One of the vaccines, Gardasil, from Merck, is made available to the poorest girls in the country, up to age 18, at a potential cost to the United States government of more than $1 billion; proposals to mandate the vaccine for girls in middle schools have been offered in 24 states, and one will take effect in Virginia this fall. Even the normally stingy British National Health Service will start giving the other vaccine — Cervarix, from GlaxoSmithKline — to all 12-year-old girls at school this September.

The lightning-fast transition from newly minted vaccine to must-have injection in the United States and Europe represents a triumph of what the manufacturers call education and their critics call marketing. The vaccines, which offer some protection against infection from sexually transmitted viruses, are far more expensive than earlier vaccines against other diseases — Gardasil's list price is $360 for the three-dose series, and the total cost is typically $400 to nearly $1,000 with markup and office visits (and often only partially covered by health insurance).

Award-winning advertising has promoted the vaccines. Before the film "Sex and the City," some moviegoers in the United States saw ads for Gardasil. On YouTube and in advertisements on popular shows like "Law and Order," a multiethnic cast of young professionals urges girls to become "one less statistic" by getting vaccinated.

The vaccine makers have also brought attention to cervical cancer by providing money for activities by patients' and women's groups, doctors and medical experts, lobbyists and political organizations interested in the disease, sometimes in ways that skirt disclosure requirements or obscure the companies' involvement.

Even critics of the marketing efforts recognize the benefits of the vaccines. Girls who get the shots are less likely to have Pap tests with worrisome results that would lead to further treatment, saving themselves anxiety and discomfort and, in those cases, saving money. When it occurs, cervical cancer is a dreadful disease; genital warts, partly prevented by the Merck vaccine, can be a painful nuisance.

But some experts worry about the consequences of the rapid rollout of the new vaccines without more medical evidence about how best to deploy them. They say that because of the aggressive marketing, even parents of girls who are far from being sexually active may feel pressured into giving them a vaccine that is not yet needed and whose long-term impact is still unclear. Legislative efforts to require girls to have the vaccine only add to the pressure.

In the United States, hundreds of doctors have been recruited and trained to give talks about Gardasil — $4,500 for a lecture — and some have made hundreds of thousands of dollars. Politicians have been lobbied and invited to receptions urging them to legislate against a global killer. And former state officials have been recruited to lobby their former colleagues.

"There was incredible pressure from industry and politics," said Dr. Jon Abramson, a professor of pediatrics at Wake Forest University who was chairman of the committee of the Centers for Disease Control and Prevention that recommended the vaccine for all girls once they reached 11 or 12........Much more at the link

Fosomax-type drugs linked to jaw necrosis

USC dentist links Fosomax-type drugs to jaw necrosis
Posted On: January 1, 2009 - 5:30pm

Researchers at the University Of Southern California, School Of Dentistry release results of clinical data that links oral bisphosphonates to increased jaw necrosis. The study is among the first to acknowledge that even short-term use of common oral osteoporosis drugs may leave the jaw vulnerable to devastating necrosis, according to the report appearing in the January 1 Journal of the American Dental Association (JADA).

Osteoporosis currently affects 10 million Americans. Fosomax is the most widely prescribed oral bisphosphonate, ranking as the 21st most prescribed drug on the market since 2006, according to a 2007 report released by IMS Health.

"Oral Bisphosphonate Use and the Prevalence of Osteonecrosis of the Jaw: An Institutional Inquiry" is the first large institutional study in the U.S. to investigate the relationship between oral bisphosphonate use and jaw bone death, said principal investigator Parish Sedghizadeh, assistant professor of clinical dentistry with the USC School of Dentistry.

After controlling for referral bias, nine of 208 healthy School of Dentistry patients who take or have taken Fosamax for any length of time were diagnosed with osteonecrosis of the jaw (ONJ). The study's results are in contrast to drug makers' prior assertions that bisphosphonate-related ONJ risk is only noticeable with intravenous use of the drugs, not oral usage, Sedghizadeh said. "We've been told that the risk with oral bisphosphonates is negligible, but four percent is not negligible," he said.

Most doctors who have prescribed bisphosphonates have not told patients about any oral health risks associated with the use of the drugs, despite even short-term usage posing a risk due to the drug's tenacious 10-year half life in bone tissue. Lydia Macwilliams of Los Angeles said no one told her about the risk posed by her three years of Fosamax usage until she became a patient of Sedghizadeh at the School of Dentistry. "I was surprised," she said. "My doctor who prescribed the Fosamax didn't tell me about any possible problems with my teeth."

Macwilliams was especially at risk for complications because she was to have three teeth extracted. The infection is a biofilm bacterial process, meaning that the bacteria infecting the mouth and jaw tissues reside within a slimy matrix that protects the bacteria from many conventional antibiotic treatments, and bisphosphonate use may make the infection more aggressive in adhering to the jaw, Sedghizadeh said. The danger is especially pronounced with procedures that directly expose the jaw bone, such as tooth extractions and other oral surgery. After her extractions, two of the three extraction sites had difficulty healing due to infection, Macwilliams said. Luckily, with treatment as well as the rigorous oral hygiene regimen USC dentists developed especially for patients with a history of bisphosphonate usage, the remaining sites slowly but fully healed. "It took about a year to heal," she said, "but it's doing just fine now."

Sedghizadeh hopes to have other researchers confirm his findings and thus encourage more doctors and dentists to talk with patients about the oral health risks associated with the widely used drugs. The results confirm the suspicions of many in the oral health field, he said. "Here at the School of Dentistry we're getting two or three new patients a week that have bisphosphonate-related ONJ," he said, "and I know we're not the only ones seeing it."
