Forest Labs Inc. Warned by FDA on Drug Study Process (Correct)
(Corrects nature of the studies referred to in the FDA warning, adds information on the version of Celexa mentioned in the warning letter)
Washington, March 24 (Bloomberg) -- Forest Laboratories Inc., a maker of brand-name and generic drugs, failed to properly assess the accuracy of drug concentrations in the human bloodstream during laboratory tests, the U.S. Food and Drug Administration said in a warning letter.
The tests involved drugs including an experimental liquid form of the company's antidepressant Celexa.
According to the FDA, the company improperly monitored quality control on studies conducted at its Farmingdale, New York facility, where the concentration of drug ingredients in human volunteers is tested.
The warning letter concentrated on ''an intellectual disagreement on our standards,'' said Lawrence Olanoff, Forest's executive vice president for scientific affairs.
In a company statement, Forest said ''none of the comments made by the FDA affects the validity of data that supports the potency, safety or efficacy of our marketed products.''
Among the seven studies the FDA said it examined during an October 1998 inspection were two for use in the approval process for a new liquid form of Celexa. The company currently sells Celexa in a tablet form with Warner-Lambert Co. The liquid version hasn't yet been approved and isn't on the market.
Celexa competes with the No. 1 antidepressant, Eli Lilly & Co.'s Prozac, and SmithKline Beecham Plc's Paxil.
In the inspection of the studies, the FDA said it found evidence that Forest didn't use proper standards to assess the purity of the solutions used in the studies, which also led to inaccurate data.
Tests ''that do not meet the (quality control) acceptance criteria should be rejected,'' said the letter, issued March 12 and released today the agency's Freedom of Information office.
The FDA said continued problems with the studies could prompt the agency to reject future studies from the company. The company has until April 5 to respond to the violations spelled out in the letter.
The FDA also examined tests for the asthma drug flunisolide, the anti-flu drug rimantadine and isosorbide dinitrate, a widely available generic drug used to treat chest pain caused by heart attacks.
The FDA sends hundreds of warning letters to companies each year, and only a small handful of them result in significant agency action. Still, the letters can be the last notice before the FDA takes steps such as holding up shipments of products or pursuing civil fines.
