Enlivex Receives Authorizations from French and Belgian Regulatory Agencies To Expand Its Phase II Sepsis Clinical Trial Into France and Belgium

Nes-Ziona, Israel, Jan. 04, 2023 (GLOBE NEWSWIRE) — Enlivex Therapeutics Ltd. (Nasdaq: ENLV, the “Company”), a clinical-stage macrophage reprogramming immunotherapy company, today announced that the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) and the Belgian Federal Agency for Medicines and Health Products (FAMHP) have cleared the amended protocol of the Company’s Phase II trial evaluating Allocetra™ in patients with sepsis. The approved protocol, which previously received clearances in Israel, Greece and Spain, enables the treatment of newly recruited patients with a frozen Allocetra™ formulation, as well as an expansion of the study’s target population, which was originally limited to patients with pneumonia-associated sepsis, to include patients whose septic condition stems from biliary, urinary tract or abdominal infections.

The Phase II trial is expected to include 80 to 160 patients across four cohorts, receiving varying doses of either Allocetra^TM or a placebo, all in addition to standard-of-care therapy. The trial’s two primary endpoints are safety (number and severity of adverse events and severe adverse events) and efficacy (change from baseline in sequential organ failure (SOFA) score) assessments throughout a 28-day follow-up period. The trial is supported by previously reported positive results from a Phase Ib investigator-initiated trial that showed vastly improved clinical outcomes, including SOFA scores, duration of hospitalization, and mortality, in Allocetra^TM-treated sepsis patients, as compared to a group of matched historical controls who received standard-of-care therapy.

Oren Hershkovitz, Ph.D., CEO of Enlivex, commented, “Expanding the study to France and Belgium with frozen formulation Allocetra^TM is an important step in the execution of our ongoing Phase II sepsis trial. We also believe that this is a notable regulatory achievement that provides additional validation for our amended study design and Allocetra^TM frozen formulation.”

ABOUT THE PHASE II SEPSIS TRIAL

Enlivex’s Phase II sepsis trial is a placebo-controlled, randomized, dose-finding, multi-center study that is currently enrolling patients across four cohorts. Patients enrolled in the study receive varying doses of Allocetra™ or placebo, all in addition to standard-of-care therapy. The trial’s two primary endpoints are safety (number and severity of adverse events and severe adverse events) and efficacy (change from baseline in SOFA score), which will be assessed throughout a 28-day follow-up period. Additionally, the trial’s secondary endpoint is 28-day all-cause mortality among other important secondary endpoints.

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.

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