P-CD19CD20-ALLO1: Potent Fully Allogeneic CAR-T Therapy Targeting CD19 and CD20 with Superior Efficacy over Single-Target Products
(ASH 2024)
- P1 | "Clinical data from Poseida and others have demonstrated safety and efficacy advantages associated with TSCM CAR-T, including for P-BCMA-ALLO1, our BCMA-targeting allogeneic CAR-T for Relapsed/Refractory Multiple Myeloma (NCT04960579). P-CD19CD20-ALLO1 CAR-T cells were superior to the CD19-targeting CAR-T product. P-CD19CD20-ALLO1, a dual-targeting, fully allogeneic TSCM-rich CAR-T product for CD19 and CD20-positive B-cell malignancies, demonstrates robust antigen-specific activity against DLBCL and CLL models and outperforms its single-targeting counterparts even in the presence of only a single antigen on target cells."

P-CD19CD20-ALLO1: A TSCM-PREDOMINANT ALLOGENEIC CAR-T THERAPY TARGETING CD19 and CD20 FOR B-CELL MALIGNANCIES DEMONSTRATES ADVANTAGES BEYOND PREVENTING ANTIGEN ESCAPE
(ICML 2025)
- P1 | "Clinical data from TSCM-rich CAR-T P-BCMA-ALLO1, our BCMA-targeting allogeneic CAR-T for R/R multiple myeloma (NCT04960579), have demonstrated favorable safety and efficacy, likely related at least in part to the undifferentiated CAR-T. P-CD19CD20-ALLO1, a dual-targeting, fully allogeneic TSCM-rich CAR-T product for CD19 and CD20-positive B-cell malignancies, demonstrates robust antigen-specific activity against diffuse large B cell lymphoma (DLBCL) and chronic lymphocytic leukemia (CLL) models as well as the phenotype and function associated with TSCM. P-CD19CD20-ALLO1 is currently being investigated in an open-label, multicenter Phase 1 study in subjects with R/R B cell malignancies (NCT06014762) and for autoimmune diseases."

(ICML 2025)
- P1 | "Several lymphodepletion (LD) dosing regimens with cyclophosphamide and fludarabine are also being evaluated for expansion of P-CD19CD20-ALLO1. After receiving LD for 3 days followed by a 2-day break, patients receive a single infusion of P-CD19CD20-ALLO1 and are followed for safety and efficacy. The dose escalation portion of the study is actively enrolling patients, and an expansion phase will follow."

Poseida Therapeutics Highlights…Preclinical Data for Dual CAR-T P-CD19CD20-ALLO1 at the 66th American Society of Hematology (ASH) Annual Meeting
(PRNewswire)
- "New preclinical data included in the poster presentation show that compared to CD19-single targeting or CD20-single targeting CAR-T cells, P-CD19CD20-ALLO1: Achieved higher and more durable killing of tumor cells over three rechallenges, even in the presence of only one tumor antigen. Exhibited higher cytotoxicity. Produced higher and more sustained levels of effector cytokines (IL-2, IFN-γ, sFasL, Granzyme A and Granulysin) that play an important role mediating the immune system response to cancers. Showed higher in vivo antitumor efficacy than the CD19-single targeting CAR-T cells."
