REDWOOD CITY, Calif., March 29, 2023 /PRNewswire/ -- Arcellx, Inc. (NASDAQ: ACLX), a biotechnology company reimagining cell therapy through the development of innovative immunotherapies for patients with cancer and other incurable diseases, today reported business highlights and financial results for the fourth quarter and year ended December 31, 2022.
“2022 was a stellar year for Arcellx, both from a business and clinical perspective. We completed a successful IPO in February, secured additional capital through a follow-on offering in June, and ended the year announcing a global partnership with Kite to co-develop and co-commercialize CART-ddBCMA in multiple myeloma. In parallel, we initiated two Phase 1 studies utilizing our dosable and controllable CAR-T technology, ARC-SparX, and our Phase 2 iMMagine-1 pivotal study and presented robust long-term data from our Phase 1 expansion study of CART-ddBCMA in multiple myeloma at ASCO and ASH. We also made significant progress on the manufacturing front, setting us up for scalable manufacturing in the future,” said Rami Elghandour, Arcellx’sChairman and Chief Executive Officer. “Leveraging our balance sheet of $580 million in cash positions us to continue building on our strong foundation as we advance our pipeline programs. Our team, in collaboration with our colleagues at Kite, remains focused on 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. We’re also beginning commercial planning as we prepare for U.S. market entry with the goal of meeting the demand of the many patients in need.”
