Kite, a Gilead Company (NASDAQ: GILD), and Arcellx, Inc. (NASDAQ: ACLX), today announced the closing of the companies' previously announced global strategic collaboration to co-develop and co-commercialize Arcellx's lead late-stage product candidate, CART-ddBCMA, for the treatment of patients with relapsed or refractory multiple myeloma. Multiple myeloma is an incurable disease for most patients and the need remains for effective, safe and broadly accessible therapies. Currently being investigated in a Phase 2 pivotal trial, CART-ddBCMA is Arcellx's T-cell therapy utilizing the company's novel synthetic binder, the D-Domain. Kite and Arcellx will jointly advance and commercialize the CART-ddBCMA asset in the U.S., and Kite will commercialize the product outside the U.S.
Arcellx, Inc. is a clinical-stage biotechnology company reimagining cell therapy by engineering innovative immunotherapies for patients with cancer and other incurable diseases. Arcellx believes that cell therapies are one of the forward pillars of medicine and Arcellx's mission is to advance humanity by developing cell therapies that are safer, more effective, and more broadly accessible. Arcellx's lead product candidate, CART-ddBCMA, is being developed for the treatment of relapsed or refractory multiple myeloma (r/r MM) in a Phase 2 pivotal trial. CART-ddBCMA has been granted Fast Track, Orphan Drug, and Regenerative Medicine Advanced Therapy designations by the U.S. Food and Drug Administration. Arcellx is also advancing its dosable and controllable CAR-T therapy, ARC-SparX, through two programs: a Phase 1 study of ACLX-001 for r/r MM, initiated in the second quarter of 2022; and ACLX-002 in relapsed or refractory acute myeloid leukemia and high-risk myelodysplastic syndrome, initiated in the fourth quarter of 2022.

For international patients, we help with practical coordination — travel planning, hospital admission guidance, and local support.
