Tempest Therapeutics furnished an investor presentation and press release outlining updated clinical data for its lead dual-targeting CAR-T candidate TPST-2003.
Across two ongoing Phase 1/2 trials in relapsed/refractory multiple myeloma and POEMS syndrome, all 15 CAR-T-naïve efficacy-evaluable patients achieved complete responses. In REDEEM-1, 10 of 10 CAR-T-naïve multiple myeloma patients reached complete response using standard IMWG criteria. In POEMS-1, all five efficacy-evaluable patients achieved complete VEGF-based responses within two months of treatment.
Including a prior investigator-initiated trial, 44 patients have received TPST-2003. Among 29 CAR-T-naïve evaluable multiple myeloma patients with measurable disease at baseline, the overall response rate was 100%, with a median progression-free survival of 23.1 months across 24 patients and the same median in those with extramedullary disease. The safety profile showed no grade ≥3 cytokine release syndrome or ICANS in REDEEM-1, though four deaths occurred in the IIT, including two therapy-related pneumonias and two from disease progression. Tempest states these results support its objective of meeting with the FDA to discuss a potential U.S. registrational study for TPST-2003 later in 2026.
