Artiva Biotherapeutics Reports First Quarter 2025 Financial Results, Recent Business Highlights

IND clearance and initiation of global basket trial exploring AlloNK^® + rituximab in refractory rheumatoid arthritis, Sjögren's disease, idiopathic inflammatory myopathies and systemic sclerosis

First trial to explore an allogeneic cell therapy in refractory rheumatoid arthritis and Sjögren's disease in the U.S.

Initial safety, translational data, and lead indication selection to be presented by year-end 2025; initial clinical response data in the lead indication to be presented in 1H2026

Longer-term clinical data from Phase 1/2 trial exploring AlloNK + rituximab in B-NHL in heavily pretreated CAR-T naïve patients to be presented at ASGCT, demonstrating complete response rates and median duration of responses in line with approved auto-CAR-T therapies, support deep B-cell depletion

Cash runway extension into Q2 2027, with cash, cash equivalents and investments of $166.0 million as of March 31, 2025

SAN DIEGO, May 08, 2025 (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 first quarter ended March 31, 2025, and highlighted recent progress.

"We are encouraged by our early experience with AlloNK^® in autoimmune disease. We have initiated regulatory submissions globally for our company-sponsored basket trial in refractory rheumatoid arthritis, Sjögren's disease, myositis and scleroderma. Notably, we are first to announce a company-sponsored allogeneic cell therapy trial in rheumatoid arthritis and Sjögren's disease in the U.S.; two sizeable indications that could benefit from AlloNK's potential ease of use and well-tolerated safety profile in the community setting," said Fred Aslan, M.D., Chief Executive Officer of Artiva.  "Since the IPO last July, we have transformed our development team and now have a deep bench of autoimmune expertise to expand and refine the clinical trial infrastructure and development strategy for AlloNK in autoimmune disease. By the end of 2025, we plan on sharing initial safety and translational data supporting AlloNK's mechanism of action and tolerability profile across multiple autoimmune diseases, as well as announcing our lead indication. In the first half of 2026, we expect to share clinical response data in our lead indication with longer follow-up to substantiate AlloNK's emerging target product profile, and to have initial insights on registrational approaches."

Dr. Aslan continued, "Our longer-term aggressive B-NHL data is maturing into a leading data set, in line with approved auto-CAR-T therapies, providing proof of concept of AlloNK's ability to deplete B-cells deeply and durably. We remain well capitalized to generate meaningful data sets and to differentiate ourselves over time from other therapeutic approaches in areas of significant unmet need in the community setting."

Investigator-initiated trial (IIT):

• Ongoing IIT Basket Trial: IIT assessing the safety, tolerability, and clinical activity of AlloNK + rituximab in patients with RA, pemphigus vulgaris, granulomatosis with polyangiitis/microscopic polyangiitis, and SLE. The trial is being conducted by Integral Rheumatology & Immunology Specialists (IRIS), in an outpatient setting at a community rheumatology clinic.
  • Initial tolerability supports prioritization of community sites for clinical development of AlloNK

AlloNK + rituximab in B-cell non-Hodgkin lymphoma (B-NHL) updates:

• Longer-term clinical data from Phase 1/2 trial exploring AlloNK + rituximab in patients with relapsed/refractory B-NHL to be presented at The American Society of Gene & Cell Therapy (ASGCT) 28th annual meeting on May 13, 2025. Abstracts are currently available on the ASGCT website
• Updated clinical data in heavily pre-treated, CAR-T naïve patients with B-NHL shows prolonged duration of response, with complete response rates and median duration of response in line with approved auto-CAR-T therapies in aggressive B-NHL patients with multiple prior lines of treatment

Other program updates:

• Preclinical data on the ablation of SLE donor B-cells with AlloNK in combination with either an anti-CD19 or anti-CD20 monoclonal antibody presented at the 2025 Pan-American League of Rheumatology Congress (PANLAR) and to be presented at the 16^th International Congress on Systemic Lupus Erythematosus (LUPUS 2025), being held May 21-24, 2025, in Toronto, Canada

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. This includes two company-sponsored trials, one in systemic lupus erythematosus for patients with or without lupus nephritis, and a basket trial across autoimmune diseases including rheumatoid arthritis and Sjögren's disease, as well as 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.
