BioNTech Shuts Down Maryland Cell Therapy Manufacturing Following CAR-T Trial Failure
- BioNTech will lay off 63 employees and wind down cell therapy manufacturing at its Gaithersburg, Maryland facility by the end of 2025 following disappointing Phase 1 trial results.
- The company discontinued development of its CAR-T candidate BNT211 targeting CLDN6 in testicular cancer and germ cell tumors due to insufficient efficacy data.
- Despite the setback, BioNTech continues studying BNT211 in other CLDN6-expressing cancers including ovarian, sarcoma, endometrial, and gastric cancers.
- The facility closure is part of broader oncology pipeline restructuring as BioNTech realigns resources and reduces global workforce by up to 1,350 jobs by 2027.
