SAN DIEGO, March 10, 2026 (GLOBE NEWSWIRE) — Artiva Biotherapeutics, Inc. (Nasdaq: ARTV) (Artiva), a clinical-stage biotechnology company whose mission is to develop effective, safe and accessible cell therapies for patients with devastating autoimmune diseases and cancers, today announced financial results for the full year ended December 31, 2025, and highlighted recent progress.
“2025 was a year of strong execution as we advanced our AlloNK program, successfully enrolling patients in community settings across autoimmune indications and prioritizing refractory RA as our lead indication,” said Fred Aslan, M.D., president and chief executive officer of Artiva Biotherapeutics. “AlloNK has the potential to redefine the treatment paradigm for refractory RA by combining the durable efficacy of deep B-cell depletion with an outpatient-ready profile suitable for community rheumatology practices.”
Dr. Aslan continued, “In 2026, our focus is to advance AlloNK from an early clinical program in the deep B-cell depletion space to what could become the first therapy in this class to initiate a registrational trial in RA, the autoimmune disease with the largest refractory population. We look forward to sharing initial clinical response data and engaging with the FDA on a potential pivotal trial design in refractory RA in the first half of 2026.”
Recent Business Highlights
Prioritized refractory RA as lead indication: Received FDA Fast Track designation for AlloNK in refractory RA and prioritized RA as the program’s lead autoimmune indication.
Despite multiple approved biologic and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs), there are more than 150,000 RA patients in the U.S. who have failed at least two prior therapies. Real-world data suggest ACR50 response rates at six months are typically in the 10 – 20% range, underscoring the significant unmet need and opportunity for AlloNK plus rituximab to drive deeper and more durable responses with a single treatment cycle.
Artiva has successfully enrolled refractory RA patients across dose levels and will provide initial clinical response data from at least 15 patients, most of whom are expected to have six or more months of follow-up, in the first half of 2026.
Demonstrated deep and consistent B-cell depletion supporting intended mechanism of action: Across patients analyzed, AlloNK plus rituximab resulted in non-quantifiable peripheral CD19+ B-cell levels by Day 13. These findings were confirmed using a high-sensitivity assay with 10- to 50-fold greater sensitivity than standard assays. Early reconstitution data demonstrated predominantly naïve and transitional B cells, consistent with immune reconstitution patterns observed with CD19-directed autologous CAR-T therapies.
Established favorable safety and outpatient feasibility profile in autoimmune disease, leading to strong enrollment: As of the Oct. 1, 2025 data cutoff, 32 patients were treated with AlloNK plus rituximab across refractory RA, Sjögren’s disease, systemic lupus erythematosus (SLE), lupus nephritis and systemic sclerosis, entirely in the outpatient setting, with the majority treated in community rheumatology clinics. The regimen was well tolerated, with no reported cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), graft-versus-host disease or hypogammaglobulinemia.
Reported continued durability in Phase 1/2 oncology trial: Presented longer-term data from the completed Phase 1/2 trial of AlloNK plus rituximab in relapsed/refractory B-cell non-Hodgkin lymphoma demonstrating a 64% complete response rate and a median duration of response not yet reached, exceeding 19.4 months at data cutoff, in line with commercially approved auto-CAR-T results in a comparable patient population.
Enhanced executive leadership to support late-stage development and capital strategy: Appointed Subhashis Banerjee, M.D. as chief medical officer and Thad Huston as chief financial officer, adding deep rheumatology development expertise, regulatory experience and global financial leadership as AlloNK advances toward potential registrational development.
Strengthened board leadership with deep immunology and commercial expertise: Appointed Dan Baker, M.D. and Elaine Sorg to the board of directors, adding extensive experience in autoimmune drug development, regulatory strategy and large-scale immunology commercialization, including leadership roles supporting major therapies for rheumatoid arthritis and other immune-mediated diseases in multibillion dollar franchises.
Upcoming Milestones
Initial clinical response data in refractory RA expected in the first half of 2026: Artiva expects to report initial clinical response data in at least 15 patients, most of whom are expected to have six or more months of follow-up.
Planned FDA interaction in the first half of 2026 to discuss potential pivotal trial design in refractory RA: Subject to feedback and alignment with the FDA, AlloNK has the potential to become the first deep B-cell depleting therapy to initiate a pivotal trial in patients with refractory RA.

About Artiva Biotherapeutics Artiva is a clinical-stage biotechnology company whose mission is to develop effective, safe and accessible cell therapies for patients with devastating autoimmune diseases and cancers. Artiva’s lead program, AlloNK® (also known as AB-101), is an allogeneic, off-the-shelf, non-genetically modified, cryopreserved NK cell therapy candidate designed to enhance the antibody-dependent cellular cytotoxicity effect of monoclonal antibodies to drive B-cell depletion. AlloNK is currently being evaluated in three ongoing clinical trials for the treatment of B-cell driven autoimmune diseases, including a company-sponsored basket trial across autoimmune diseases that includes rheumatoid arthritis and Sjögren’s disease and an investigator-initiated basket trial in B-cell driven autoimmune diseases. Artiva’s pipeline also includes CAR-NK candidates targeting both solid and hematologic cancers. Artiva was founded in 2019 as a spin out of GC Cell, formerly GC Lab Cell Corporation, a leading healthcare company in the Republic of Korea, pursuant to a strategic partnership granting Artiva exclusive worldwide rights (excluding Asia, Australia and New Zealand) to GC Cell’s NK cell manufacturing technology and programs.
Artiva is headquartered in San Diego, California. For more information, please visit www.artivabio.com.
