研究概览
简要总结
This is a multicenter, open-label study to evaluate the safety and efficacy of C-CAR088 in patients with relapsed or refractory multiple myeloma. The phase Ib part of this study is to determine the recommended phase 2 dose (RP2D) of C-CAR088 in the targeted patient population.
详细描述
The study includes the following sequential procedures: Screening, Apheresis and C-CAR088 manufacturing, Baseline testing, Lymphodepletion, C-CAR088 infusion, and Follow-up Visit. Two dose levels of C-CAR088 will be tested during the phase Ib part to determine RP2D, which will be further evaluated during the phase II part.

入选标准
- •≥ 18 years of age, male or female patients
- •Relapsed or refractory multiple myeloma
- •Have been treated with ≥ 3 prior lines of therapy, including at least one proteasome inhibitor and one immunomodulatory drug, and had progressed during or within 12 months post the last treatment.

排除标准
- •Any known allergies to the components or excipients of the C-CAR088 cell product
- •Prior allogeneic hematopoietic stem cell transplantation (HSCT) at anytime, or autologous stem-cell transplantation (ASCT) within 12 weeks prior to apheresis
