Brief Summary

This study is a multi-center, single-arm clinical study to evaluate the efficacy, safety, pharmacokinetics and pharmacodynamic characteristics of CT103A as the first-line treatment in newly diagnosed high-risk multiple myeloma subjects with induction chemotherapy as bridging therapy.

Detailed Description

Before enrollment, subjects will receive chemotherapy regimen of either Bortezomib-Lenalidomide-Dexamethasone (VRD), Bortezomib-Cyclophosphamide-Dexamethasone (PCD) or Bortezomib-Adriamycin-Dexamethasone (PAD) as induction therapy for 3 cycles. Evaluation will be made after 2 cycles of chemotherapy. If the subject is not intended to have stem cell transplantation or unsuitable for autologous hematopoietic stem cell transplantation (ASCT) as judged by the investigator, he/she will receive the 3rd cycle of chemotherapy. If the subject meets the inclusion criteria, he/she will be enrolled in the study.

Peripheral blood mononuclear cell (PBMC) will be collected to manufacture CT103A. After PBMC collection, the subject will receive another cycle of chemotherapy and evaluated. Lymphodepletion with fludarabine and cyclophosphamide will be performed for three consecutive days. After 1-day rest, subjects will receive a single infusion of CT103A at 1.0 ×10^6 /kg. Subjects will be followed in the study for a minimum of 2 years after CT103A infusion. Long-term follow-up for lentiviral vector safety will be followed for up to 15 years after CT103A infusion.

Study Groups

CT103A in Newly Diagnosed Subjects With High-risk Multiple Myeloma

Fully Human BCMA Chimeric Antigen Receptor Autologous T Cell Injection（CT103A）will be infused at 1.0 x 10\^6 CAR+ T cells/kg in newly diagnosed subjects with high-risk multiple myeloma

Group Type: EXPERIMENTAL

Fully human BCMA chimeric antigen receptor autologous T cell injection (CT103A)

Intervention Type: DRUG

CT103A is a customized, BCMA-targeted genetically modified autologous T cell immunotherapy, which can identify and eliminate malignant and normal cells expressing BCMA. CAR specifically recognizes BCMA with single chain fragment variable (ScFv), and promotes the activation, proliferation, cytokine secretion and target cell killing of CAR-T through the CD3ζ domain. And 4-1BB enhances the expansion and persistence of CT103A.

CT103A will be infused at 1.0×10^6 /kg via intravenous drip within 24h to 72h after chemotherapy conditioning regimen at the recommended infusion rate of 3-5 mL/min.
