What have they got to hide? The Famciclovir case

Pending further description of methodology in Sheffield Actonel studies, my attention was drawn to a similar scandal in another parallel scientific universe. It involves the drug Famciclovir (Famvir) and is discussed at Pharmawatch and Healthcare Renewal.

Famvir is used for treatment of herpes zoster, and genital/labial herpes. The case involves a nine year delay before partial publication of findings which had adverse implications for the sponsor. As in the Actonel case, it also involved protracted denial of raw data to academic authors. The study and editorial were finally published a few weeks ago (1,2).

The authors relate that (1):

"....companies are understandably wary of devoting resources to a report that is not in favor of their product. Although we received data tables and listings for this study, we were not able to obtain data tapes to verify the analyses and to conduct what we consider the most clinically relevant analyses"

Dr Wald, the first author, notes in correspondence that:

"We asked for raw data and we were not given it. Initially, we were told that the company has other priorities and that they have not looked at the data. Then company has changed hands and we were told that they no longer had it. But we were given the summary tables and report from which i wrote the paper. The whole process took several years."

Should we as clinicians really be prescribing Famciclovir given this corporate approach to science, and given that we don't really know what was hidden from the authors?

The response of the medical profession and medical ethicists to such problems has been feeble. EBM specialists who collect Clinical Evidence scrupulously fail to document attempts to control, suppress or delay that evidence. It is also puzzling that the drug regulators have no interest in contamination of the scientific literature upon which doctors and patients rely. The malaise is reflected in the recent puzzling assertion in the UK that the drug regulatory body (MHRA) has no remit to investigate or to be concerned about allegations of scientific misconduct or contamination of the scientific literature after a drug is licensed. What then are they for?

We would do well to remind ourselves of the story of Betty Dong and the "thyroid storm" (3, 1996 Editorial in Science, another Editorial)

In 1990, Dong, a researcher at UCSF was funded by Boots to carry out research on a widely use thyroid treatment (Synthroid). She discovered the Boots drug was no more effective than three much cheaper competitors. When she tried to publish, Boots threatened to sue. The publication was withdrawn. She received no institutional support. Company executives attempted successfully to publish an inaccurate version of the findings while excluding Dong and threatening legal action. Nine years later the sordid details were exposed in the press and Dong’s paper was published. In 1999/2000 the company paid $170 million to settle class action lawsuits. However it is estimated that the company made a profit of $3billion in inflated costs during the nine year delay. No company executives were prosecuted. The regulators turned a blind eye.
