P-BCMA-ALLO1 Allogeneic CAR-T Cells in the Treatment of Subjects With Multiple Myeloma
Bu Faz 1 (Phase 1) çalışma, nükseden veya tedaviye dirençli multipl miyelom (multiple myeloma) hastalarında donörden elde edilen (allojenik) P-BCMA-ALLO1 T kök bellek hücresi (Tscm) CAR-T tedavisini açık etiketli, doz artırımlı ve çok kohortlu bir tasarımla incelemektedir; protokolde rimidusid ve metotreksat da yer almaktadır. Katılım için 18 yaş ve üzeri olmak, aktif multipl miyelom tanısının doğrulanmış ve hastalığın ölçülebilir olması, ayrıca daha önce proteazom inhibitörü ve immünomodülatör ajan içeren tedaviler alınmış olması gerekmektedir.
