Tempest Outsources Manufacturing for Key CAR-T Candidate Ahead of 2026 Trial

  • Tempest Therapeutics has selected Cincinnati Children’s Applied Gene and Cell Therapy Center (AGCTC) as a contract development and manufacturing organization (CDMO) for TPST-2003, its dual-targeting CAR-T therapy.
  • The agreement focuses on technology transfer and IND-enabling manufacturing, with most activities planned for completion by Q3 2026.
  • Interim Phase 1/2a data showed 100% complete response (CR) in six evaluable patients, accelerating the development timeline.
  • Tempest intends to file an Investigational New Drug (IND) application in Q4 2026, targeting a U.S. registrational study in 2026.
  • TPST-2003 is being developed in China by Novatim, with Tempest holding exclusive rights outside of China, India, Turkey, and Russia.

Tempest's reliance on a CDMO for critical manufacturing steps is a common strategy for biotech firms lacking in-house capabilities, but introduces external dependencies and potential delays. The accelerated timeline and promising early data position TPST-2003 as a potential competitor in the crowded multiple myeloma CAR-T landscape, where existing therapies have already generated billions in revenue. The partnership with AGCTC, a recognized leader in CGT CDMO services, suggests Tempest is prioritizing speed and expertise in preparation for a competitive market.

Execution Risk
The success of TPST-2003 hinges on AGCTC’s ability to efficiently execute the technology transfer and manufacturing processes within the aggressive Q3 2026 timeline, which could impact the IND filing and subsequent trial initiation.
Clinical Data
The upcoming presentation of REDEEM-1 trial data will be critical in validating the interim results and influencing investor sentiment regarding TPST-2003’s efficacy and potential.
Regulatory Pathway
The FDA’s receptiveness to a dual-targeting CAR-T approach, particularly given the complexity of manufacturing and potential safety concerns, will significantly shape the trajectory of TPST-2003’s development.
