"Delivering our novel CAR-T therapy to multiple myeloma patients is at the heart of our mission," said Rami Elghandour, Arcellx's Chairman and Chief Executive Officer. "With the closing of our Kite partnership in the first quarter, we believe we are well capitalized to fund our operations through the first half of 2025. We remain laser-focused on key drivers of our business which include completing enrollment of iMMagine-1, initiating iMMagine-2 in earlier multiple myeloma lines, and presenting longer-term data from our Phase 1 expansion study of CART-ddBCMA. This is a pivotal and exciting time for our organization, and we are excited about our progress made to date and look forward to continuing our momentum."
