Artiva Biotherapeutics (ARTV) stock surged on Friday after the U.S. Food and Drug Administration (FDA) granted Fast Track Designation to the clinical-stage biotechnology company’s AlloNK with rituximab for the treatment of refractory rheumatoid arthritis (RA). Refractory RA is a type of arthritis that doesn’t respond to standard treatment methods and causes persistent joint or systemic inflammation.

Artiva Biotherapeutics has provided details about what it will do next with the development of AlloNK. The company plans to share patient safety data in November. Following that, it expects to release clinical response data from more than 15 refractory RA patients in the first half of 2026. In that same window of time, it also expects to conduct regulatory interactions with the FDA.
Artiva Biotherapeutics CEO Fred Aslan said, “We are prioritizing refractory RA as our lead autoimmune indication for AlloNK given the size of this underserved population. Despite the many approved therapies in RA, there are over 100,000 patients in the United States who remain treatment refractory and could potentially benefit from a deep B-cell depleting therapy.”
