• Temporomandibular joint (TMJ) osteoarthritis is a degenerative, debilitating and progressive disease, the second most common musculoskeletal condition affecting five to 12% of the population globally
  • TMJ causes pain and stiffness in the jaw, making it difficult to chew
  • TMJ osteoarthritis currently has no long-term effective treatments

NESS-ZIONA, Israel I April 03, 2025 I Enlivex Therapeutics Ltd. (Nasdaq: ENLV, the “Company” or “Enlivex”), a clinical-stage macrophage reprogramming immunotherapy company, today announced that the first patient has been dosed in an investigator-initiated Phase I trial to evaluate the safety, tolerability and initial efficacy of Allocetra™ for injection into the temporomandibular joint (TMJ) in patients suffering from TMJ osteoarthritis.

The study will be conducted by the Rheumatology Unit at Sheba Medical Center in collaboration with the Department of Oral and Maxillofacial Surgery at Sheba Medical Center. Notably, Sheba Medical Center was recently ranked among the top 10 hospitals in the world by Newsweek.

Dr. Einat Galamidi, CMO of Enlivex, commented, “This study will provide a preliminary evaluation of the safety and potential effect of AllocetraTM for the treatment of TMJ osteoarthritis, which affects a joint that is critical for daily function. We are pleased to report that the injection of AllocteraTM into the first patient’s TMJ was successfully completed with no complications.”

The trial currently plans to recruit six patients who have insufficiently responded to conventional therapies for TMJ osteoarthritis. The trial’s primary safety endpoint will measure the frequency and severity of adverse events and serious adverse events, and efficacy endpoints will assess changes from baseline in TMJ pain, joint functionality, and other disease parameters for up to 12 months following administration of Allocetra™.

ABOUT ALLOCETRA™

Allocetra™ is being developed as a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Diseases such as solid cancers, sepsis, and many others reprogram macrophages out of their homeostatic state. These non-homeostatic macrophages contribute significantly to the severity of the respective diseases. By restoring macrophage homeostasis, Allocetra™ has the potential to provide a novel immunotherapeutic mechanism of action for life-threatening clinical indications that are defined as “unmet medical needs,” as a stand-alone therapy or in combination with leading therapeutic agents.

ABOUT TEMPOROMANDIBULAR JOINT (TMJ) OSTEOARTHRITIS

TMJ disorders are the second most common musculoskeletal condition affecting five to 12% of the population globally, with an annual health cost estimated at $4 billion1. Osteoarthritis of the TMJ is the most common form of arthritis in the TMJ, causing pain and stiffness in the jaw. It may become difficult to chew. TMJ osteoarthritis is a degenerative disease of the joint, which culminates in the progressive destruction of all soft and hard tissue components of the TMJ. For patients who present in early adulthood with severe clinical symptoms and catastrophic radiographic changes, there are significant implications for management, including the potential need for early total joint replacement. There are currently no effective long-term treatments for this disease2.

ABOUT ENLIVEX

Enlivex is a clinical stage macrophage reprogramming immunotherapy company developing Allocetra™, a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Resetting non-homeostatic macrophages into their homeostatic state is critical for immune system rebalancing and resolution of life-threatening conditions.
