ORR increases to 82% with additional Partial Response in azer-cel CAR T Relapsed Ph 1b trial

In September 2025, Imugene announced that a total of thirteen out of sixteen patients had achieved an ORR of 81%, defined as either Complete Response, (the disappearance of signs of cancer in response to treatment) or Partial Response, (defined as cancer reduction by at least 50%).  Since then, an additional patient has become evaluable, achieving a Partial Response at Day 28 scan evaluation increasing the best ORR to 82% with fourteen out of seventeen patients showing response to treatment.  The Complete Response (CR) rate continues to evolve as enrollment progresses and patients transition from partial to complete response, with an average time to best response seen in one to three months. The durability of response is also deepening in patients treated with azercel in combination with interleukin-2 (IL-2).
