About

This is a first-in-human study to evaluate the feasibility, safety and preliminary antitumor efficacy of autologous T cells genetically engineered with a novel B-cell Maturation Antigen (BCMA)-specific chimeric antigen receptor (CAR) and manufactured with a new process. CAR-T cells will be investigated as a single agent in multiple myeloma

Full description

This is a phase I, open label study to characterize the safety and tolerability of a novel B-cell Maturation Antigen (BCMA)-specific chimeric antigen receptor (CAR) manufactured with a new process. In the dose escalation part (Part A) of the study, the anti-BCMA CAR-T cell therapy will be studied in adult multiple myeloma (MM) subjects who are relapsed and/or refractory. In the dose evaluation part (Part B) of the study, the anti-BCMA CAR-T cell therapy will be studied in newly diagnosed adult subject with MM.

Enrollment: 96 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Part A: Subjects with MM who are relapsed and/or refractory to at least 2 prior treatment regimens, including an IMiD (e.g. lenalidomide or pomalidomide), a proteasome inhibitor (e.g. bortezomib, carfilzomib), and an approved anti-CD38 antibody (e.g. daratumumab), if available, and have documented evidence of disease progression (IMWG criteria)
• Part A: ECOG performance status that is either 0 or 1 at screening
• Part B: Subjects with newly diagnosed multiple myeloma (NDMM) who have received a minimum of 4 and up to 6 cycles of standard induction therapy with VRd, D-VRd, or D-Rd, and have achieved a response of PR or better. One cycle of CyBorDex is allowed prior to induction.
• Part B: ECOG performance status that is either 0,1 or 2 at screening
• Measurable disease as defined by the protocol
• Adequate hematological values
• Must have a leukapheresis material of non-mobilized cells accepted for manufacturing

Exclusion criteria

• Prior administration of a genetically modified cellular product including prior BCMA CAR-T therapy. Patients who have received prior BCMA-directed bi-specific antibodies or antibody-drug conjugates (ADC) are not excluded.
• Autologous HSCT within 6 weeks prior to enrollment or any prior history of allogeneic hematopoietic stem cell transplant (HSCT)
• Chemotherapy or any concomitant anti-cancer therapies (other than protocol prescribed lymphodepletion (LD) chemotherapy) within 2 weeks prior to apheresis
• Treatment with small molecule targeted antineoplastics within 2 weeks of apheresis collection or 5 half-lives whichever is shorter
• Have received antibodies or immunotherapies (other than daratumumab) within 4 weeks prior to apheresis collection. Daratumumab within 3 weeks prior to apheresis collection.
