Tempest, Cincinnati Children’s AGCTC partner for TPST-2003 registrational study

Tempest Therapeutics (TPST) announced the selection of Cincinnati Children’s Applied Gene and Cell Therapy Center as the lead contract development and manufacturing partner to conduct the formal technology transfer of TPST-2003, Tempest’s dual-targeting CD19/BCMA CAR-T therapy under development for the treatment of relapsed/refractory multiple myeloma. Tempest recently announced that, as of a January 31, 2026 data cutoff, a total of 36 patients with rrMM had received one infusion of TPST-2003, including 24 patients in a prior Phase 1/2 investigator-initiated trial and 12 patients in the ongoing REDEEM-1 trial, representing one of the largest datasets evaluating a CD19/BCMA dual-targeting CAR-T therapy. As of the data cutoff, all six efficacy evaluable patients enrolled in the REDEEM-1 trial had achieved a complete response according to the International Myeloma Working Group uniform response criteria. Among 25 evaluable patients with measurable disease at baseline across both studies, the overall response rate was 100%. Tempest plans to present the results of the REDEEM-1 trial and updated results from the IIT at a scientific meeting later this year.
