Ernexa Therapeutics Inc., a preclinical-stage biopharmaceutical company, focuses on the development of allogenic induced pluripotent stem cell–derived mesenchymal stem cell (iMSC) therapies for solid tumors and autoimmune diseases. The company’s lead programs include ERNA-101, an allogenic pro-inflammatory cytokine (IL-7/IL-15) secreting iMSC for ovarian cancer, and ERNA-102, an anti-inflammatory cytokine (IL-10) secreting iMSC for rheumatoid arthritis, with additional candidates advancing in preclinical development. Ernexa operates under licensed collaborations and leverages off-the-shelf cellular platforms to enable scalable, regulated therapeutic products.
Founding year and headquarters: Founded in 2018; headquarters location is Cambridge, Massachusetts. The company maintains operations and development activities in the United States, with a focus on advancing preclinical assets toward clinical readiness and potential future clinical trials.
Recent major changes and strategic moves (latest 1–2 years): Rebranded from Eterna Therapeutics Inc. to Ernexa Therapeutics in March 2025 to align with strategic focus; establishes ErnexaTX2, a Texas-based subsidiary formed to support ongoing preclinical development of ERNA-101 and to underpin anticipated clinical activities in 2026; reports ongoing execution toward clinical milestones, including advancement of ERNA-101 and ERNA-201 programs and exploration of strategic collaborations to accelerate clinical development and regulatory strategy. These steps reflect a shift toward expanded operational footprint, increased preclinical and regulatory readiness, and disciplined resource allocation to drive first-in-human initiatives.
Industry and segments: Biotechnology; cell therapy; regenerative medicine; immuno-oncology; autoimmune diseases.
Geographic footprint: United States with research and development activities in Massachusetts and Texas for preclinical and potential clinical operations; potential collaborations and partnerships may extend to international regulators and clinical development networks as programs progress.
Subsidiaries and corporate relationships: Wholly owned subsidiary ErnexaTX2 in Texas established to support preclinical development and future clinical operations; parent company relationships reflect a unified strategy around allogenic iMSC therapies and collaboration-driven development pathways.
