Alkermes and Indevus Announce Positive Results from Phase 2a Clinical Study of ALKS 27 for the Treatment of COPD

CAMBRIDGE & LEXINGTON, Mass.--(BUSINESS WIRE)--Sept. 26, 2007--Alkermes, Inc. (NASDAQ: ALKS) and Indevus Pharmaceuticals, Inc. (NASDAQ: IDEV) today announced positive preliminary results from a randomized, double-blind, placebo controlled phase 2a clinical study of ALKS 27 in patients with chronic obstructive pulmonary disease (COPD). In the study, single doses of ALKS 27 demonstrated a rapid onset of action and produced a significant improvement in lung function (p less than .0001) over 24 hours compared to placebo. ALKS 27 is an inhaled formulation of trospium chloride using Alkermes' proprietary AIR(R) pulmonary delivery system.

"These preliminary data are encouraging and suggest that ALKS 27 may have several key attributes, including daily administration, rapid onset of action and prolonged duration of bronchodilation that could enhance clinical outcomes for COPD patients," stated Elliot Ehrich, Chief Medical Officer of Alkermes.

"The results of this trial demonstrate that ALKS 27 has the potential to offer patients a new option in the treatment of COPD, a large and underserved disease affecting millions of people each year," stated Glenn L. Cooper, M.D., Chairman and CEO of Indevus. "Based on these positive results, we are moving forward with Alkermes to identify a partner for the future development and commercialization of ALKS 27."

Trial Design and Results

The phase 2a randomized, double-blind, placebo-controlled crossover study was designed to assess the safety, tolerability, pharmacokinetics and efficacy of ALKS 27 in 24 patients with moderate to severe COPD. During the study, patients received a single administration of two different dose levels of ALKS 27 and placebo, with each dose separated by a wash out period. The primary objective of the study was to assess the effect of ALKS 27 as measured by the area under the curve (AUC) of FEV1 over a 24-hour time period. FEV1 is an important clinical measure of lung function defined as the amount (volume) of air expelled during the initial second of forced exhalation.

In the study, patients treated with a single dose of ALKS 27 showed a statistically significant improvement in lung function (p less than 0.0001) compared to placebo. The onset of action of ALKS 27 was rapid and observed as early as 15 minutes post-treatment.

ALKS 27 was well tolerated, and all 24 enrolled patients completed the study. No treatment-related adverse events were reported in this study.

ALKS 27 is an inhaled formulation of trospium chloride, a muscarinic receptor antagonist that relaxes smooth muscle tissue and has the potential to improve airflow in patients with COPD. Trospium chloride is the active ingredient in SANCTURA(R), Indevus' currently marketed product for overactive bladder. The formulation under development for ALKS 27 is specifically designed for inhalation utilizing Alkermes' proprietary AIR pulmonary delivery system.

About COPD

Chronic obstructive pulmonary disease (COPD), characterized by airflow obstruction and loss of expiratory force, comprises mostly smoking-related diseases such as emphysema and chronic bronchitis. COPD is the fourth largest cause of death in the U.S. and is projected to be the third leading cause of death for both males and females by 2020. It is estimated that over 12 million adults have been diagnosed with COPD and approximately 24 million adults have evidence of impaired lung function, indicating COPD is significantly under-diagnosed. There is no known cure at the present time. In the U.S., estimated direct healthcare costs for COPD are in excess of $20 billion and surveys indicate a severe quality of life impact to COPD patients. The total U.S. market for COPD product sales is over $3 billion.(1)
