SAN DIEGO, Aug. 29, 2024 (GLOBE NEWSWIRE) -- Artiva Biotherapeutics, Inc. (Nasdaq: ARTV), 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 second quarter ended June 30, 2024, and highlighted recent progress.

“Artiva is at an inflection point as we advance AlloNK® in clinical development across multiple autoimmune indications and transition to a publicly traded company,” said Fred Aslan, M.D., Artiva’s Chief Executive Officer. “With two trials in autoimmunity underway, we are focused on the potential of AlloNK® in delivering effective, safe, and accessible cell therapies for patients with devastating autoimmune disease.”

Recent Business Highlights

AlloNK®

• Treatment initiated in the first patient in an investigator-initiated basket trial (IIT) exploring AlloNK® in combination with rituximab in patients with rheumatoid arthritis, pemphigus vulgaris, granulomatosis with polyangiitis/microscopic polyangiitis, and SLE. The trial is being conducted by Integral Rheumatology & Immunology Specialists (IRIS), a community rheumatology clinic, demonstrating the potential to bring AlloNK® to patients in a community setting in addition to academic and transplant centers. The study is assessing the safety, tolerability, and clinical activity of AlloNK® (also known as AB-101).  
• Announced treatment of the first LN patient in Artiva sponsored Phase 1/1b trial in April 2024. To Artiva's knowledge, this marks the first patient to receive an allogeneic, off-the-shelf NK cell therapy in a U.S. clinical trial for treatment of an autoimmune disease. In the Phase 1/1b trial, AlloNK® will be administered in combination with rituximab or obinutuzumab. The trial was expanded to include patients with SLE without kidney involvement.
• Expect to report initial data on autoimmune indications from at least one of the Phase 1/1b trial or the basket IIT in the first half of 2025.
  

Corporate and Financial Updates

• Significantly extended cash runway through the completion of Artiva’s initial public offering (IPO). Strengthened balance sheet with approximately $179.0 million in gross proceeds from the IPO in July 2024, which extends cash runway at least through the end of 2026 and through key clinical data milestones.
