Frequently asked questions about Allogeneic NK Cells

What is Allogeneic NK Cells used for?

Allogeneic NK Cells, also known as AlloNK, is an investigational cell therapy being studied for refractory Rheumatoid Arthritis (RA) and other B-cell dependent rheumatologic diseases, including Idiopathic Inflammatory Myopathies, Systemic Sclerosis, and Sjogren Syndrome. It is in Phase 2 clinical development and is not yet approved.

What does Allogeneic NK Cells target?

Allogeneic NK Cells is a non-genetically modified, cord blood-derived natural killer cell therapy. It is being studied in combination with rituximab, which targets B cells. The therapy is designed to work in B-cell dependent rheumatologic diseases, though the specific molecular target of the NK cells themselves is not detailed.

Who makes Allogeneic NK Cells?

Allogeneic NK Cells is being developed by Artiva Biotherapeutics, Inc., a biopharmaceutical company. The company's stock is traded under the ticker symbol ARTV on the NASDAQ.

What phase is Allogeneic NK Cells in?

Allogeneic NK Cells is currently in Phase 2 clinical development. It is an investigational therapy and has not received FDA approval. The ongoing Phase 2 trial is recruiting participants to evaluate the therapy in refractory Rheumatoid Arthritis and related conditions.

What clinical trials is Allogeneic NK Cells in?

Allogeneic NK Cells is being studied in a single Phase 2 clinical trial with the identifier NCT06991114. The trial is titled 'AlloNK, an Allogeneic Non-genetically Modified, Cord Blood-derived NK Cell Therapy, in Combination With Rituximab, Studied in Relapsing Forms of B-cell Dependent Rheumatologic Diseases.' It is currently recruiting and aims to enroll 90 participants.

Is Allogeneic NK Cells the same as AlloNK?

Yes, Allogeneic NK Cells is also known as AlloNK. The clinical trial NCT06991114 refers to the therapy as AlloNK, an allogeneic non-genetically modified, cord blood-derived NK cell therapy. Both names refer to the same investigational cell therapy being developed by Artiva Biotherapeutics.
