Artiva is a clinical-stage biotechnology company whose mission is to develop effective, safe and accessible cell therapies for patients with debilitating autoimmune diseases. Artiva’s lead program, AlloNK® (also known as AB-101), is an allogeneic, off-the-shelf, non-genetically modified, cryopreserved natural killer (NK) cell therapy candidate designed to enhance the antibody-dependent cellular cytotoxicity effect of monoclonal antibodies to drive B-cell depletion. Artiva is developing AlloNK in combination with anti-CD20 antibodies in autoimmune disease, with the goal of delivering auto-CAR-T-like activity through a scalable, outpatient-administered treatment regimen compatible with community rheumatology settings. AlloNK is currently being evaluated across B-dell driven autoimmune diseases, including refractory rheumatoid arthritis (RA), Sjögren disease, systemic sclerosis and myositis. Initial clinical data have demonstrated encouraging activity across multiple autoimmune indications, along with a tolerability profile supportive of outpatient administration. Artiva plans to initiate a Phase 3 registrational trial evaluating AlloNK in refractory RA in 2026.
