Recent Company History

Over the last few months, Enlivex combined digital-asset treasury initiatives with corporate housekeeping and financing. Multiple RAIN token exchange listings in early 2026 generally coincided with small positive or flat moves, while the shift to trading exclusively on Nasdaq also aligned with a mild gain. A $212,000,000 private placement and strategy update in December 2025 drew a stronger positive reaction, highlighting investor focus on capital and strategic positioning alongside clinical progress such as today’s Allocetra update.

Analysis

The stock moved +8.8% in the session following this news. A strong positive reaction aligns with the FDA’s IND clearance for a global Phase 2b Allocetra™ trial in moderate-to-severe knee osteoarthritis, building on a prior 134-patient Phase 1/2a study with statistically significant results. Investors have previously responded well to strategic and financing updates, including a $212,000,000 private placement, but ongoing at-the-market capacity of up to $250,000,000 could remain a consideration.

Key Terms

investigational new drug (ind), phase 2b, placebo-controlled, intra-articular injections, +4 more

8 terms

investigational new drug (ind) regulatory

"has cleared its Investigational New Drug (IND) application for Allocetra™"

An investigational new drug (IND) is a drug or biologic that is being tested but has not yet been approved for general use; it is the application and formal status that allows a company to begin human clinical trials under regulator oversight. Investors care because an IND marks the transition from lab work to human testing — like getting a permit to run real-world experiments — which creates important milestones, costs, timelines and regulatory risk that drive a development-stage company's value.

phase 2b medical

"late-stage global Phase 2b study in Age-Related Primary Moderate-to-Severe"

Phase 2b is a stage in the development of a new medicine or treatment where researchers test its effectiveness and safety in a larger group of people. This step helps determine whether the treatment works well enough to move forward and if it has manageable side effects, which is important for investors because successful results can lead to potential approval and market opportunity.

placebo-controlled medical

"multicenter, randomized, double-blind, placebo-controlled clinical trial"

"Placebo-controlled" describes a testing method where one group receives the actual treatment or intervention, while another group receives a harmless, inactive version called a placebo. This approach helps determine whether the real treatment has genuine effects beyond psychological expectations. For investors, understanding this ensures confidence that reported benefits are real and not influenced by bias or false perceptions.

intra-articular injections medical

"evaluate the efficacy and safety of intra-articular injections of Allocetra™"

Intra-articular injections are treatments where medication or other therapeutic agents are injected directly into a joint space, like putting oil straight into a car hinge to reduce friction. For investors, they matter because they represent a targeted way to treat joint pain or disease that can reduce side effects and sometimes improve outcomes, influencing a product’s clinical appeal, market demand, regulatory pathway, and potential revenue.

at-the-market offering financial

"updating an at-the-market offering: it is now offering up to"

An at-the-market offering is a method companies use to sell new shares of stock directly into the open market over time, rather than all at once. This allows them to raise money gradually, similar to selling small pieces of a product instead of a large batch. For investors, it means the company can access funding more flexibly, but it may also increase the supply of shares and influence the stock’s price.

rule 424(b)(3) regulatory

"Prospectus Filed Pursuant to Rule 424(b)(3)"

Rule 424(b)(3) is a U.S. Securities and Exchange Commission filing rule that governs how updated prospectus information about a securities offering is formally added to an existing registration statement. For investors, seeing a 424(b)(3) filing means the company has officially recorded new offering details – like the number of shares, pricing range or other terms – so it’s a reliable place to check the latest, legally required disclosures; think of it as the official addendum to a product manual that must be filed before the product is sold.

form 3 regulatory

"title": "[Form 3] Enlivex Ltd. Initial Statement of Beneficial Ownership""

Form 3 is the initial public filing that officers, directors and large shareholders must submit to report their ownership of a company’s securities when they become insiders. It acts like an opening inventory sheet that gives investors a starting point to see who holds significant stakes and to spot later trades or potential conflicts of interest, helping assess insider confidence and transparency.

private placement financial

"plans after a $212,000,000 private placement, including a new digital asset"

A private placement is a way for companies to raise money by selling securities directly to a small group of investors instead of through a public offering. This process is often quicker and less regulated, making it similar to offering a special, exclusive investment opportunity to select individuals or institutions. For investors, it can provide access to unique investment options that are not available on public markets.

• 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.
