ENLV Enlivex Therapeutics Ltd

 Enlivex Therapeutics Ltd. (Nasdaq: ENLV, the “Company”), a clinical-stage macrophage reprogramming immunotherapy company, today announced the completion of the dosing and initial follow-up period for the first patient in its Phase I clinical trial evaluating the safety, tolerability and potential therapeutic effect of Allocetra™ following injection into an affected joint in patients with psoriatic arthritis. No safety concerns were recorded following the dosing of the first patient.

The trial currently plans to recruit six patients who have insufficiently responded to conventional therapies for psoriatic arthritis. The primary safety endpoint will measure the frequency and severity of adverse events and serious adverse events, and secondary endpoints will include assessments of change from baseline in pain and other parameters of disease activity for up to 12 months following administration of Allocetra™.

Dr. Oren Hershkovitz, CEO, commented, “Complementing our ongoing clinical trial in osteoarthritis, which is a low-grade chronic inflammatory joint disease, this new study provides an opportunity to assess Allocetra™ in a high-grade inflammatory joint disease such as psoriatic arthritis, which is another indication with poor treatment alternatives that we believe potentially presents a substantial market opportunity for Enlivex.”

ABOUT PSORIATIC ARTHRITIS1

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis that typically occurs in individuals with psoriasis, a skin condition characterized by red, scaly patches. PsA can affect any joint in the body, leading to pain, stiffness, and swelling. It can also cause inflammation in other parts of the body, including the eyes, heart, and gastrointestinal tract. The global market for psoriatic arthritis (PsA) treatments, valued at approximately $10.8 billion in 2023, is estimated to grow substantially, with certain projections indicating the market will reach $20.5 billion by 2032, growing at a compound annual growth rate (CAGR) of 7.4% from 2024 to 2032. Other analysis anticipates the PsA treatment market will increase from $9.97 billion in 2023 to $24.87 billion by 2031, representing a CAGR of 12.1% from 2024 to 2031. The current landscape of PsA treatment is marked by significant challenges, including limited efficacy, side effects, high costs, long-term safety concerns, underdiagnosis, and issues with patient adherence. Addressing these challenges requires ongoing research and development of more effective, safer, and affordable treatments, along with efforts to improve diagnosis and patient education.
