"The completion of patient enrollment in SYNERGY is an important milestone for Zalicus. We are grateful to the investigators and patients for participating in this study and look forward to reporting top-line results in the third quarter of 2012," commented Mark H.N. Corrigan, MD, President and CEO of Zalicus.

Study Design and Objectives

The Phase 2b clinical trial titled SYNERGY (SYNavivE for Reducing signs and sYmptoms of rheumatoid arthritis trial), is a 12-week, five-arm, global, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of Synavive as a treatment for the signs and symptoms of RA in subjects with moderate to severe disease. The trial is being conducted in up to 60 centers throughout the United States, Europe and Latin America. The primary objective of the trial is to evaluate Synavive efficacy compared to placebo, while key additional secondary objectives include evaluating the efficacy of Synavive compared to its individual components (2.7mg of Prednisolone and 360mg of Dipyramidamole) as well as how Synavive performs in comparison to 5mg of Prednisone. Subjects who complete the core SYNERGY trial are eligible to participate in a one-year extension study designed to investigate the long-term safety and durability of response for Synavive.
