CAMBRIDGE, Mass.--(BUSINESS WIRE)--CombinatoRx, Incorporated (NASDAQ: CRXX), today announced preliminary top-line results from COMET-1 (CRx-102 Osteoarthritis Multi-center Evaluation Trial), the Company's Phase 2b clinical trial designed to evaluate the safety and efficacy of Synavive (CRx-102) in subjects with symptomatic knee osteoarthritis (OA). While there was a trend in favor of Synavive, and an observed dose-response relationship, the combination did not demonstrate statistical significance compared to placebo for WOMAC question #1 measuring pain while walking on a flat surface (the primary endpoint), nor when compared to prednisolone alone. Analyses of the full dataset from the study remain ongoing.
