Seattle, April 30, 2002 --- Lilly ICOS LLC announced today that the company received an 'approvable letter' for the drug Cialis (tadalafil, IC351) from the U.S. FDA. The impotency drug Cialis is a phosphodiesterase (PDE-5) inhibitor, distinguished from Viagra by a long duration of action and great selectivity, According to the company press release, which was posted to both the ICOS and the Eli Lilly websites, FDA approval was contingent upon "...successful completion of additional clinical pharmacology studies, labeling discussions, and manufacturing inspections."

Cialis logoCialis has shown in clinical trials that it works faster and lasts far longer than Viagra. But because the medicine stays in the body longer, the FDA may want Lilly and ICOS to investigate the lingering effects of the drug to see if any safety risks arise. Lilly officials in a conference call with analysts declined to describe the nature of the new Cialis clinical trials, but called them "confirmatory'' studies. One Lilly executive said the U.S. Food and Drug Administration was concerned with the potential for recreational use or abuse of erectile dysfunction drugs.

Eli Lilly Co. logoFDA Approval of Cialis now appears to be pushed back approximately one year, well into 2003, the delay being widely interpreted as a disappointment to Lilly ICOS, which had hoped to launch the product in mid-2002. Speaker-training seminars for physician experts, originally planned to coincide with a product launch and scheduled for early May, were postponed indefinitely.

ICOS logoLilly ICOS is a joint venture between the pharmaceutical giant Eli Lilly Co. of Indianapolis, IN and the biotech start-up firm ICOS of Seattle, WA. CEO of ICOS is George Rathman, who was a founder of Amgen, and the board includes William H. Gates of Microsoft , who is also a major investor in the company.
