Nes-Ziona, Israel, April 29, 2024 (GLOBE NEWSWIRE) -- Enlivex Therapeutics Ltd. (Nasdaq: ENLV, the “Company” or “Enlivex”), a clinical-stage macrophage reprogramming immunotherapy company, today issued the following update to shareholders from Chief Executive Officer, Oren Hershkovitz.
Dear fellow shareholders,
I have been serving as the Chief Executive Officer of Enlivex for the last four and a half years. During that period, we have been working diligently to develop our drug product candidate, AllocetraTM, as a first-in-kind modulator of a spectrum of negative immune reactions from low, chronic, debilitating inflammation to high-grade, life-threatening cytokine storms.
To-date, we have completed numerous pre-clinical studies across multiple disease models, infused AllocetraTM in more than 100 patients and witnessed the encouraging safety profile and potential effect of AllocetraTM. We saw a patient with COVID-19 in critical condition saying goodbye to his loved ones via a video call, as the consensus in the ICU was that he would not last through the night, and that patient received an infusion of AllocetraTM and within hours had a complete reversal of his condition, resulting in his release from the hospital several days later. We also saw a patient with an ultra-rare condition, vanishing bone disease in the shoulder joint. In this case, not only was the joint cartilage completely eroded, but the shoulder bone itself had completely disintegrated. After four years of escalation and nine months of continued hospitalization, the patient received a compassionate treatment of injections of matched AllocetraTM to the shoulder joint. We witnessed the outstanding recovery of the inflammatory condition resulting in hospital discharge after five weeks and no re-hospitalization in the following three years. We have witnessed, first-hand, the potential effect of AllocetraTM as a life-changer, and all of us at Enlivex are committed to translate that first-hand experience into a global one.
On April 11, 2024, we released the top-line data from a placebo-controlled, randomized, dose-finding, multi-country, multi-center Phase II trial, which evaluated frozen-formulation Allocetra™ in addition to standard of care in patients with sepsis associated with pneumonia, biliary, urinary tract, or peritoneal infections.
The trial randomization resulted in a higher risk profile of the AllocetraTM group as compared to the control group, making some of the data challenging to interpret. In small clinical trials, these things happen from time to time. While we are not happy that this occurred, we are pleased that AllocetraTM demonstrated (i) a potential indication of effect not only stand-alone but also as compared to the control group in high-risk urinary tract infection (UTI) sepsis patients, and (ii) a favorable safety and tolerability profile.
We believe that these results have increased the likelihood of AllocetraTM to eventually change the lives of millions of people around the world, whether in sepsis or osteoarthritis. We believe that each of these two market segments represents a potential multi-billion dollar commercial opportunity for Enlivex. The Phase II sepsis study also demonstrated the giant leap we made in transforming AllocetraTM into a completely off-the-shelf drug that can be easily shipped and stored in clinical sites globally and easily administered by physicians, including in complex environments, such as in intensive care units. As we continue to analyze the data from the sepsis study, we will also assess whether collaborators may seek to work with us on a larger sepsis study, which could be in high-risk UTI sepsis patients or across multiple patient populations.
Some asked us recently what the link is between a potential indication of effect in sepsis and the treatment of osteoarthritis. We note that the basic mechanism of action of AllocetraTM is to positively modulate macrophages that are at the core of the particular inflammatory cause. We chose osteoarthritis after careful review of the scientific literature that showed high correlation between inflamed macrophages and osteoarthritis severity and clinical manifestation. Therefore, the potential indication of effect and the favorable safety and tolerability profile of AllocetraTM as demonstrated in the sepsis trial are very important, in our opinion, and we expect that these increase the probability of success in osteoarthritis.
We announced earlier this week that the first two patients had been dosed in the Company’s multi-country, randomized, controlled Phase I/II trial evaluating AllocetraTM in up to 160 patients with moderate to severe knee osteoarthritis. We anticipate two significant milestones relating to osteoarthritis, the first of which being results from the ongoing clinical trial of AllocetraTM in patients with end-stage knee osteoarthritis, which we expect in Q3 2024. These patients have been suffering from knee osteoarthritis for many years, and, following various treatments, eventually have reached the stage requiring knee replacement surgery. We are offering them, as a last resort, a single injection of AllocetraTM to the knee. We started with the first patient approximately seven months ago, and we are continuing to enroll patients. Our second milestone, which we expect in Q3 2025, is top-line results from the Company’s multi-country, randomized, controlled Phase I/II trial evaluating AllocetraTM in up to 160 patients with moderate to severe knee osteoarthritis.
We expect that our existing cash resources will provide adequate coverage, plus a safety margin, for obtaining the data from these two important trials. I am privileged to lead such an enthusiastic and dedicated team at Enlivex who accomplished and executed so much in the past four and a half years The team at Enlivex is genuinely excited about the prospect of AllocetraTM to be a game changer in the world of medicine. We appreciate your continued support. It takes time, courage and tenacity to change the world, and we hope to do just that.
Sincerely,
Oren Hershkovits, Ph.D., CEO
ABOUT SEPSIS
Sepsis is a life-threatening disease with no therapies approved by the U.S. Food and Drug Administration (“FDA”) and a high unmet medical need. According to the U.S. Centers for Disease Control and Prevention, each year, at least 1.7 million adults in the United States develop sepsis, with approximately 270,000 dying of the disease.
About UTI
Urinary tract infection is the second most common infectious disease affecting more than 150 million people globally annually. Up to 31% of sepsis cases start as UTIs, representing up to 9.8 million cases annually worldwide, leading to as many as 1.6 million deaths.1
ABOUT KNEE OSTEOARTHRITIS2
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 FDA or the European Medicines Agency that have been demonstrated to arrest, slow or reverse progression of structural damage in the joint.
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 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 and life-debilitating conditions.
