-- The companies share design of global Phase 3 trial, iMMagine-3; will evaluate anito-cel in patients exposed to both an immunomodulatory (lMiD) drug and an anti-CD38 monoclonal antibody --

-- Anito-cel will be manufactured from Kite’s Frederick, Maryland facility for iMMagine-3 as the successful technical transfer is complete --

-- Remain on track to present preliminary data from the iMMagine-1 trial by end of the year --

Arcellx, Inc. (NASDAQ: ACLX) and Kite, a Gilead Company (NASDAQ: GILD), today announced several key operational updates on their partnered anitocabtagene autoleucel (anito-cel) multiple myeloma program. Anito-cel is the first BCMA CAR T to be investigated in multiple myeloma that utilizes Arcellx’s novel and compact D-Domain binder.

The companies shared the design of a global, Phase 3 randomized controlled clinical trial, iMMagine-3, which Kite expects to start in the second half of this year. The trial will compare the efficacy and safety of anito-cel randomized against the standard of care (SOC) in patients with relapsed and/or refractory multiple myeloma (rrMM) who have received one to three prior lines of therapy, including an immunomodulatory drug (lMiD) and an anti-CD38 monoclonal antibody.

Kite’s facility in Frederick, Maryland will manufacture anito-cel for this trial. This follows the completion of the technical transfer from a third-party contract manufacturing organization to Kite, as well as the transfer of the Investigational New Drug (IND) application for anito-cel, which has been cleared by the U.S. Food and Drug Administration.

“Our global iMMagine-3 trial will evaluate anito-cel as a second through fourth line treatment in patients with multiple myeloma who were previously exposed to both an immunomodulatory drug and an anti-CD38 monoclonal antibody,” said Rami Elghandour, Arcellx’s Chairman and Chief Executive Officer. “The iMMagine-3 study allows us to maximize the impact of anito-cel as it captures what will become the largest second line patient population based on the current treatment paradigm, as anti-CD38 therapies move to front line treatment. This population represents an emerging significant unmet clinical need allowing us to provide access to a unique patient population. In addition, the completion of the technical transfer to Kite allowed us to accelerate our development program and launch iMMagine-3 globally, which will enable broader and earlier patient access to anito-cel.”

“We are pleased to start the Phase 3 pivotal trial, iMMagine-3, in the second half of this year given the tremendous unmet need that remains in patients with relapsed and/or refractory multiple myeloma,” said Cindy Perettie, Executive Vice President, Kite. “As we prepare for this pivotal program, we look forward to leveraging our manufacturing expertise to further position anito-cel as a potential best-in-class cell therapy. We know manufacturing quality, reliability, and speed are critically important as every day matters for these patients.”
