A complaint filed with the federal Office of Research Integrity alleged that a group of psychiatrists, including an associate professor at the Harvard Medical School, signed their names to an academic paper written by a communications firm hired by a major pharmaceutical company.

Gary S. Sachs, a researcher affiliated with Massachusetts General Hospital, is one of five doctors identified in the formal accusation filed July 8 by University of Pennsylvania professor Jay D. Amsterdam.

The psychiatrists allowed the medical communications company Scientific Therapeutics Information, hired by SmithKline Beecham, to draft a paper using their names, according to the complaint. The paper, according to Amsterdam, suggested that the antidepressant Paxil can help treat some cases of bipolar disorder.
