Study of CT071 Injection in RRMM or PPCL
Bu Erken Faz 1 (Early Phase 1) klinik çalışma, nükseden veya tedaviye dirençli multipl miyelom (multiple myeloma) ya da primer plazma hücreli lösemi (primary plasma cell leukemia) hastalarında CT071 enjeksiyonunun güvenliliğini ve etkililiğini araştırmaktadır. Tedavi, tek gruplu tasarımla uygulanan deneysel bir CAR-T hücre infüzyonudur. Katılım için 18 yaş ve üzeri olmak, gönüllü olarak bilgilendirilmiş onam vermek, tüm çalışma işlemlerini tamamlayabilecek durumda olmak ve daha önce belirtilen miyelom tedavilerini almış olmak gerekmektedir.
