Azer-cel, an allogeneic (allo) CD19 CAR T, in combination with low-dose interleukin-2 (IL-2) demonstrates clinical activity in patients with large B-cell lymphoma (LBCL) who relapsed after autologous (auto) CAR T (ASH 2025) - P1 | "Pts receivedlymphodepletion with fludarabine (30 mg/m²/day) and cyclophosphamide (750 mg/m²/day) for 3 days(Aug/Cy), followed by azer-cel infusion (500 × 10⁶ cells) on Day 0 and SC low-dose IL-2 (1 million IU daily)on Days 1-14. Azer-cel followed by low-dose SC IL-2 demonstrates encouraging clinical activity in pts withLBCL who relapsed after prior autologous CD19 CAR T therapy, which remains a significant unmetmedical need. Promising response and CR rates, early evidence of durability, robust CAR T-cell expansionand a manageable safety profile support further investigation of this regimen as a potential treatmentoption for these patients."

Imugene Ltd…has won crucial backing from the US Food and Drug Administration (FDA), with written minutes from a recent Type C meeting confirming support to advance its off-the-shelf CAR T candidate azercabtagene zapreleucel (azer-cel) into a registrational Phase 3 study. (Proactiveinvestors) - "The meeting, held on November 21, 2025, focused on the proposed pathway to registration for azer-cel in diffuse large B cell lymphoma (DLBCL). The FDA endorsed Imugene’s planned regimen for the pivotal program, which combines augmented lymphodepletion, a fixed dose of 500 million azer-cel cells and 14 days of low-dose subcutaneous interleukin-2 (IL-2). According to Imugene, the minutes provide 'clear alignment' across key elements of the late-stage strategy, including study design, patient population, endpoints and Chemistry Manufacturing Controls (CMC) expectations."
