Quality Longevity Company Enlivex Receives Investigational New Drug (IND) Clearance from the FDA for Phase 2b Trial of Allocetra in Age-Related Primary Moderate-to-Severe Knee Osteoarthritis

• Enlivex's first regulatory approval for a late-stage global Phase 2b study in Age-Related Primary Moderate-to-Severe Knee Osteoarthritis following the implementation of its dual-engine value creation model:  A clinical-stage quality longevity program powered by a prediction markets treasury strategy.
  
   
• IND clearance follows the positive 3 and 6-month data readout from the Company's Phase 1/2a multicenter, randomized, double-blind, placebo-controlled clinical trial, which enrolled 134 patients, and demonstrated a robust, durable, clinically meaningful, and statistically significant treatment effect in older patients with knee osteoarthritis.

Nes-Ziona, Israel, March 23, 2026 (GLOBE NEWSWIRE) -- Enlivex Ltd. (NASDAQ:ENLV) ("Enlivex" or the "Company"), a quality longevity company, today announced that the U.S. Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for Allocetra™, the Company's clinical-stage immunotherapy, for the treatment of patients with moderate-to-severe age-related symptomatic primary knee osteoarthritis (OA).

The FDA's clearance enables Enlivex to initiate a global, multicenter, randomized, double-blind, placebo-controlled Phase 2b clinical trial designed to evaluate the efficacy and safety of intra-articular injections of Allocetra™ in patients with moderate-to-severe age-related symptomatic primary knee osteoarthritis, which is one of the most prevalent and disabling diseases worldwide, affecting more than 32 million Americans today and projected to impact 78 million Americans by 2040.

This is the first regulatory clearance obtained by the Company following the implementation of its dual-engine value creation model, which is centered on the development of a clinical-stage quality longevity program powered by a prediction markets treasury strategy.

Oren Hershkovitz, Ph.D, CEO of Enlivex, commented, "We are very pleased to have received FDA clearance to initiate the Phase 2b clinical trial of Allocetra™ in patients with age-related primary knee osteoarthritis. This milestone represents an important step toward our mission of improving the quality of life of an aging population that is suffering from this debilitating disease with poor availability of treatment options. In our previous clinical study, Allocetra™ demonstrated a robust, durable, and clinically meaningful treatment effect lasting at least six months, with increasing benefit observed in older patient populations. We look forward to enrolling the first patients into the Phase 2b and believe Allocetra™ has the potential to address a major unmet medical need for elderly patients suffering from knee osteoarthritis while supporting a strong commercial opportunity for Enlivex."

The Phase 2b trial has been designed to be statistically powered to evaluate key efficacy endpoints, including change from baseline in pain and physical function compared with placebo, measured at three- and six-months following treatment. Additional endpoints include changes in quality-of-life measures and functional mobility assessments.

About Knee Osteoarthritis

Knee osteoarthritis (KOA) is one of the most prevalent and disabling diseases worldwide, affecting more than 32 million Americans today and projected to impact 78 million Americans by 2040. There are currently no approved disease modifying therapies; treatment is largely limited to pain relief, intra articular steroids, or surgery, and the burden increases sharply with age. By age 60, KOA affects roughly 30% of the population, and about half of knee OA patients are 60 years and older. This demographic is expanding with global aging trends, underscoring the need for new, durable therapies.
