Indevus Announces FDA Acceptance of IND for NEBIDO(R)

Company to Commence Pharmacokinetic Trial in Men with Hypogonadism

LEXINGTON, Mass.--(HSMN NewsFeed)--March 9, 2006--Indevus Pharmaceuticals, Inc. (NASDAQ: IDEV ) today announced that the U.S. Food and Drug Administration ("FDA") has accepted the Company's Investigational New Drug ("IND") application for NEBIDO, its long-acting injectable testosterone preparation for the treatment of male hypogonadism. The Company intends to begin its pharmacokinetic study by the end of March.

"We are pleased that the FDA, upon review of the clinical and non-clinical data package from the work of our partner Schering AG, has agreed with the design of our proposed pharmacokinetic study. The primary endpoint will require assessment of the average serum testosterone levels (Cavg) at steady state, measured in hypogonadal men receiving NEBIDO via intramuscular injection every 12 weeks," stated Glenn L. Cooper, M.D., chairman, president and chief executive officer of Indevus. "While our assessment of the available European data indicates steady state levels are achieved by the third injection of NEBIDO, the FDA advised us that it would be preferable to measure our endpoint at the fourth injection to confirm steady state levels. We have agreed with this approach and assuming positive results, we anticipate submitting an NDA in the second quarter of calendar 2007. As part of this trial, we will also study other unique attributes of the drug to support the future commercialization of NEBIDO."

"We have recently entered the hypogonadism market with our acquisition of DELATESTRYL®, a short-acting injectable testosterone product," stated John H. Tucker, executive vice president and chief marketing officer. "The experience we are gaining in this therapeutic area with urologists and endocrinologists will be invaluable in planning the launch of NEBIDO. Our market research and early market development indicates that a long-acting 3-month injectable testosterone product would have a significant role in the treatment of hypogonadal men."
