Enlivex Therapeutics to Showcase Allocetra's Potential in Osteoarthritis at OARSI 2025 World Congress

Presentations to underscore Allocetra^TM's novel mechanism targeting immune imbalance in joint disease

Ness-Ziona, Israel, April 23, 2025 (GLOBE NEWSWIRE) -- Enlivex Therapeutics Ltd. (NASDAQ:ENLV, the "Company")), a clinical-stage macrophage reprogramming immunotherapy company, today announced that it will present two poster abstracts at the Osteoarthritis Research Society International (OARSI) 2025 World Congress on Osteoarthritis, taking place April 24-27, 2025, in Incheon (Seoul), South Korea.

"These presentations at OARSI 2025 will highlight the growing body of evidence supporting Allocetra's^TM potential as a novel therapeutic approach for osteoarthritis," said Oren Hershkovitz, PhD, Chief Executive Officer of Enlivex. "We believe that restoring macrophage homeostasis may address the underlying drivers of chronic joint inflammation and cartilage degradation, potentially offering a promising new treatment pathway for millions of patients worldwide."

The presentations will feature data from both preclinical and clinical studies evaluating Allocetra™, Enlivex's proprietary, off-the-shelf macrophage reprogramming cell therapy, in patients with osteoarthritis. Allocetra™ is designed to reprogram macrophages into a homeostatic state, thereby promoting immune balance and resolving chronic inflammation.

Allocetra™ has demonstrated favorable safety and promising efficacy signals in Phase I/II studies in moderate and end-stage osteoarthritis, including substantial and durable pain reduction, improved joint function, and avoidance of knee replacement surgery. Preclinical studies have further supported its unique mechanism of action in modulating macrophage-driven inflammation.
