Bush Admin no puede volcar documentos del FDA

Por Justin Blum

La administración de Bush no pudo conformarse con los documentos que buscaban de una citación del congreso relacionados con Ketek antibiótico Sanofi-Aventis SA.

Un subcomité investigador del comité de la energía y del comercio de la casa buscó los papeles del informe usados para preparar a comisión Andrew von Eschenbach de la administración del alimento y de la droga para el testimonio que él dio en una audiencia en la droga en marcha. La respuesta de la administración fue lanzada hoy por el panel.

El subcomité comenzó el año pasado a investigar si von Eschenbach dio testimonio engañoso en Ketek en la audiencia. The commissioner and the FDA are under scrutiny from lawmakers who say the agency hasn’t done enough to ensure the safety of Ketek and other medications. The subcommittee is holding a hearing today on Ketek, which has been linked to fatal side effects.

“The department has serious concerns about providing the kind of materials the committee has subpoenaed,” said officials of the FDA and its parent agency, the Health and Human Services Department, in a letter to the committee.

Providing “such highly confidential and deliberative materials used to prepare witnesses testifying before Congress risks chilling the open exchange of views that is essential to the effective conduct of agency business,” wrote Vincent J. Ventimiglia Jr. of the health department and Susan C. Winckler of the FDA.

The agency offered to brief the committee on issues concerning von Eschenbach’s testimony, and the panel hasn’t responded, according to the letter.

`Evidence of Perjury?’

Representative John D. Dingell, a Michigan Democrat who is chairman of the Energy and Commerce panel, said at today’s hearing that he supports holding the health secretary, Michael Leavitt, in contempt for failing to comply with the subpoena.

“What is in those briefing books that he does not want either my Republican colleagues or our side to see?” Dingell said. “Is there evidence of perjury? Are there statements embarrassing to the administration?”

The panel has been investigating the FDA’s 2004 approval of Ketek. Lawmakers have said the drug made by Paris-based Sanofi is an example of the FDA’s weak oversight. The agency approved the product even after certain data suggested safety risks and agency scientists expressed concern.

The FDA prohibited marketing Ketek for sinusitis and bronchitis last year after it was linked to liver damage and death in some patients. The drug remains on the U.S. market for pneumonia.

Accuracy of Testimony

During the March 22 hearing before the investigative subcommittee, lawmakers questioned the accuracy of von Eschenbach’s written testimony about Ketek.

People with first-hand knowledge of the FDA’s oversight of Ketek “have also raised questions about whether the commissioner or those who helped prepare his testimony intentionally misled the subcommittee,” wrote Dingell and Representative Bart Stupak, a Democrat from Michigan, in a letter to Leavitt after last year’s hearing. Stupak is chairman of the investigative panel.

The letter from the lawmakers included an article quoting David Ross, a former FDA scientist who worked on Ketek, saying von Eschenbach’s written testimony contained erroneous comments about the agency’s handling of the medication. Ross, who detailed his objections to the testimony to reporters at the hearing, took issue with descriptions of what the FDA knew about a falsified clinical trial and what information regulators took into account when approving the drug.

Clinical Trial Scrutinized

Today’s hearing focuses on what Aventis, a predecessor company to Sanofi, knew about falsified results in a clinical trial of Ketek run by Maria “Anne” Kirkman-Campbell, a researcher who pleaded guilty to mail fraud in the case and was sent to prison. Sanofi has repeatedly said the company didn’t know about the fraud before submitting the data to the FDA.

Aventis failed to supervise properly the researchers in the Ketek trial, the FDA said in an October warning letter to Sanofi. The company didn’t “adequately investigate” reports that Kirkman-Campbell produced false data and enrolled ineligible patients, the letter said.

“Aventis was not aware of fraud until after it had submitted the study to the FDA,” Sanofi spokeswoman Emmy Tsui said last month in an e-mailed statement. The company has “learned to improve policies and procedures” and is “committed to conducting clinical trials that are rigorous, ethical and compliant,” she said.
