Organogenesis Holdings (ORGO) announced positive interim analysis results from its second Phase 3 clinical trial of ReNu for knee osteoarthritis treatment. The analysis, covering 50% of 474 planned patients with moderate to severe knee OA, focused on the 6-month primary endpoint. The independent Data Monitoring Committee recommended proceeding without modifications or sample size increases, confirming favorable results and consistent safety profile. The fully enrolled 594-patient trial is evaluating ReNu versus saline control through intra-articular injection, with the primary endpoint measuring knee pain reduction using the WOMAC pain scale. Knee OA affects nearly 31.1 million Americans, projected to reach 34.4 million by 2027.
