Summary

CRx-102 is a synergistic combination drug candidate containing the cardiovascular drug dipyridamole and a very low dose of the glucocorticoid prednisolone. CRx-102 is believed to work through a novel mechanism of action in which dipyridamole selectively amplifies the anti-inflammatory and immunomodulatory activities of the glucocorticoid without replicating the dose-dependent adverse effects. CRx-102 has been associated with clinical benefit in proof of concept studies in subjects with hand OA and RA. This is the first study to explore the efficacy of CRx-102 in knee OA. It is considered a dose-finding study and will also compare the potential benefits of CRx-102 treatment to both prednisolone administered alone and to placebo in this indication.

Clinical Details

Official title: A Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study to Evaluate the Efficacy of CRx-102 in Subjects With Symptomatic Knee Osteoarthritis and Optional One-Year Extension

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: Change From Baseline to Day 98 Using the WOMAC Pain Question #1

Secondary outcome: To Assess the Efficacy of the CRx-102 Compared to Placebo on the Change From Baseline to Day 98 Using the Full WOMAC Pain, Stiffness, Physical Function Parameters, and Patient Global Assessment VAS.
