SAN DIEGO - Poseida Therapeutics, Inc. (NASDAQ: PSTX), a biopharmaceutical company with a market capitalization of $916 million and impressive year-to-date returns of 178%, has presented interim clinical data from its Phase 1 trial of P-BCMA-ALLO1, a therapy for relapsed/refractory multiple myeloma (RRMM), at the 66th ASH Annual Meeting and Exposition. According to InvestingPro analysis, the company's stock is trading near its 52-week high, reflecting strong investor confidence in its clinical developments. The data includes new profiling of patient responses from an optimized lymphodepletion arm, demonstrating consistent cellular expansion and persistence of the therapy across different subgroups.
The P-BCMA-ALLO1 therapy, which is being developed in collaboration with Roche, has shown a 91% overall response rate (ORR) in the optimized lymphodepletion arm, including a 100% ORR in BCMA-naïve patients. The treatment also exhibited a differentiated safety profile with no dose-limiting toxicities and low rates of common side effects, all Grade 2 or less. This development comes as Poseida demonstrates strong revenue growth of 203% in the last twelve months, though InvestingPro data indicates the company maintains a focus on research and development with current negative profit margins.
In addition to P-BCMA-ALLO1, Poseida introduced preclinical data for P-CD19CD20-ALLO1, its first dual CAR-T therapy targeting B-cell malignancies. The preclinical results suggest higher and more durable tumor cell killing compared to single-target CAR-T cells, with increased cytotoxicity and sustained effector cytokine levels.
A case study was also presented, showcasing the reactivation of an autologous Poseida CAR-T therapy with a T-cell engager in a patient with relapsed multiple myeloma. The patient achieved and maintained a stringent complete response over 12 months post reactivation, indicating the potential of TSCM-based CAR-T therapies for long-term remission.
P-BCMA-ALLO1 has been granted Orphan Drug and Regenerative Medicine Advanced Therapy designations by the FDA for multiple myeloma. The Phase 1/1b trial is ongoing, with more information available on clinicaltrials.gov (NCT04960579). P-CD19CD20-ALLO1 is also in a Phase 1 study for B-cell malignancies (NCT06014762), with initial clinical data expected in 2025.
This news is based on a press release statement and reflects interim data that may change as more patient data become available. Poseida Therapeutics continues to explore the efficacy and safety of its CAR-T therapies in clinical trials. The company maintains a strong financial position with a current ratio of 3.2, indicating solid liquidity to support its ongoing research initiatives.
