Enlivex Announces Positive Interim Data Readout from a Phase I/II Trial Evaluating Allocetra in End-Stage Knee Osteoarthritis

Key Highlights

●

Enrolled patients with severe knee osteoarthritis who were indicated for knee-replacement surgery received a single local injection of Allocetra^TM into the knee as a “last resort”

●

Three-month data readout showed a significant reduction in pain and a favorable safety profile

Pain reduction: patients reported an average pain reduction of 64% from baseline

Complete Pain Resolution: 33% of patients reported complete pain relief, from an average pain level of 9 to a pain level of 0; pain scale used in the study ranged from 0 (no pain) to 10 (maximum pain)

Avoidance of Surgery: 89% of patients did not proceed with knee replacement surgery at three months post-injection

Safety: No severe adverse events related to Allocetra™ were reported

Ness-Ziona, Israel, June 17, 2024 (GLOBE NEWSWIRE) -- Enlivex Therapeutics Ltd. (Nasdaq: ENLV, the “Company”), a clinical-stage macrophage reprogramming immunotherapy company, today released a positive interim data readout from a Phase I/II investigator-initiated clinical trial of Allocetra^TM in patients with end-stage knee osteoarthritis who had been indicated for knee replacement surgery.

In this study, patients with end-stage knee osteoarthritis are offered a single Allocetra^TM injection to the knee as a potential “last resort” alternative for pain resolution and knee functionality in lieu of knee-replacement surgery. A total of nine patients have been enrolled and treated with a single Allocetra^TM injection to the knee and evaluated for at least three months following treatment. Patients reported pain using a scale of zero (0, representing no pain) to ten (10, representing maximum pain).

At the three-month follow up, a substantial reduction (64%) in average reported pain was observed compared to baseline (Figure 1), with 89% (8/9) of treated patients reporting an improvement in their knee pain compared to their baseline pain prior to treatment, and 33% (3/9) of the patients reporting complete pain relief from an average pain level of 9 to a pain level of 0.

During the three-month period post injection of Allocetra^TM, only a single patient (1/9, 11%) decided to move forward with knee-replacement surgery, while 89% (8/9) of the patients decided not to proceed with such surgery.

In all cases, dosing was successfully completed, and no severe related adverse events were reported following treatment.

The investigator-initiated trial is led by Amir Oron, M.D., a senior specialist in Orthopedics and Chief of Hand Surgery and Microsurgery at the Kaplan Medical Center in Rehovot, Israel. Dr. Oron stated, “I am pleased with the interim results of this innovative trial, demonstrating the safety of an Allocetra^TM injection to the knee in nine patients with severe end-stage knee osteoarthritis. The initial signal of response to the Allocetra^TM injection is encouraging, especially as these patients have attempted multiple other treatments with no lasting improvement. These patients have severe osteoarthritis of the knee and need better treatment options to replace or delay progression to extensive surgery.”

Einat Galamidi, M.D., Vice President, Medical of Enlivex stated, “After a robust experience with systemic infusions of Allocetra^TM across multiple clinical studies, this is the first report of clinical outcomes following a focused Allocetra^TM injection to the joint. We believe that the results confirm the safety of Allocetra^TM in the local setting and pave the way to further explore the potential therapeutic utilization of Allocetra^TM in joint diseases with inflammatory involvement.”

Recruitment to the study and long-term follow up are ongoing. The study aims to enroll a total of 18 patients to be treated with a single injection of Allocetra^TM to the afflicted knee. Patients are assessed for safety following dosing, and pain and function responses to treatment up to 12 months following injection.

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 KNEE OSTEOARTHRITIS

Osteoarthritis is by far the most common form of arthritis, affecting more than 32.5 million Americans and more than 300 million individuals worldwide. About half of knees with ACL injuries develop osteoarthritis within 5 to 15 years. 78 million Americans are projected to have osteoarthritis by the year 2040. Symptomatic knee osteoarthritis is particularly prevalent and disabling, with 40% of men and 47% of women developing knee osteoarthritis in their lifetimes. Osteoarthritis accounts for over one million hospitalizations annually in the United States, primarily for total joint replacement. The burden of osteoarthritis is enormous, and the need for treatments that reduce pain and attendant disability for persons with osteoarthritis is critical. There are currently no medications approved by either the U.S. Food and Drug Administration or the European Medicines Agency that have been demonstrated to arrest, slow or reverse progression of structural damage in the joint.

ABOUT ENLIVEX

Resetting non-homeostatic macrophages into their homeostatic state is critical for immune system rebalancing and resolution of life-threatening conditions.
