Celyad Successfully Doses First Patient with CYAD-01 Produced with OptimAb Manufacturing Process


Celyad (Euronext Brussels and Paris, and Nasdaq: CYAD), a clinical-stage biopharmaceutical company focused on the development of CAR-T cell-based therapies, today announced the successful administration of CYAD-01 produced with the OptimAb manufacturing process to a patient enrolled in cohort 3 (300 million cells) of the Phase 1 DEPLETHINK trial.

Jean-Pierre Latere, Chief Operating Officer of Celyad said: “The dosing of the first patient with CYAD-01 manufactured with the OptimAb process marks another important milestone for our company. The OptimAb manufacturing process has shown exciting activity in preclinical models and we believe that the integration of the manufacturing process into our autologous relapsed/refractory acute myeloid leukemia program should help us to improve upon the initial signals we have observed to date with CYAD-01. We look forward to reporting preliminary data from patients enrolled in the DEPLETHINK trial treated with CYAD-01 produced with the OptimAb process by the end of the year.”
