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 sm…
