Treatment for Patients With Osteoarthritis (OA)

June 20, 2008 updated by: Amgen

A Randomized, Double-Blind, Placebo-Controlled, Multiple Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of Systemic AMG 108 in Subjects With Osteoarthritis (OA)

The purpose of this study is to evaluate the clinical benefit (change in Western Ontario and McMaster University Osteoarthritis Index [WOMAC] pain score) of AMG 108 (300 mg subcutaneously [SC] every 4 weeks) in subjects with OA.
