Newhawk: Associated Press 4/30/97 Grand Jury Probes Halcion Record By ED WHITE KALAMAZOO, Mich. (AP) A federal grand jury has been investigating whether Upjohn Co. hid safety concerns about the controversial sleeping pill Halcion, the company said. The company, now known as Pharmacia & Upjohn Inc., made the disclosure in a document filed last month with the Securities and Exchange Commission in Washington. The principal focus of the testimony involved tapes and disks containing Halcion clinical data and analyses, the company said in its annual 10K report. Three company employees and a former worker have testified before the grand jury, the report said. ``There's clearly been no attempts to hide data or falsify data,'' Dr. Goran Ando, an executive vice president of the company, said Tuesday after Pharmacia & Upjohn's annual meeting. ``We've shown this over and over again.'' Ando said he had no knowledge about the status of the investigation. Halcion was the world's topselling sleeping pill until allegations arose that it could provoke violent reactions. It still is sold worldwide, although Britain banned it in 1991. The Food and Drug Administration has examined Halcion many times since 1982, lowering the dose and adding to the label warnings of such side effects as anxiety, behavior changes and abnormal thinking. In a report to Congress 11 months ago, the FDA said it could not conclude that Upjohn, based in Kalamazoo, did anything wrong. But it also sent its findings to federal prosecutors in western Michigan. Citing grand jury secrecy rules, prosecutors in Grand Rapids declined to comment. Federal grand juries generally are convened for 18 months to consider a variety of criminal cases. In its annual report to shareholders, Pharmacia & Upjohn said it is involved in several liability lawsuits over Halcion.
