Primary Outcome Measures :
  1. Proportion of subjects experiencing Dose Limiting Toxicities at increasing doses of ALLO-715 [ Time Frame: 28 Days ]
    Dose limiting toxicities are defined as ALLO-715-related adverse events with onset within 28 days following infusion of ALLO-715.

Secondary Outcome Measures :
  1. Proportion of subjects experiencing Dose Limiting Toxicities with ALLO-647 in combination with fludarabine and/or cyclophosphamide, or ALLO-647 alone, prior to ALLO-715 [ Time Frame: 33 days ]
    Dose limiting toxicity is defined as ALLO-647-related adverse events with onset within 33 days following first infusion of ALLO-647.

  2. Cellular kinetics of ALLO-715 [ Time Frame: up to 24 months ]
    Levels of anti-BCMA CAR T cells in blood

  3. Pharmacokinetics of ALLO-647 [ Time Frame: up to 24 months ]
    Serum concentration levels of ALLO-647

  4. Incidence of immunogenicity against ALLO-715 and ALLO-647 [ Time Frame: up to 24 months ]
  5. Immune monitoring after lymphodepletion regimen [ Time Frame: up to 24 months ]
    Detection of the following circulating cells: T cell subset, B lymphocytes, and NK cells

  6. Anti-tumor activity of ALLO-715 [ Time Frame: up to 24 months ]
    overall response rate

  7. Anti-tumor activity of ALLO-715 [ Time Frame: up to 24 months ]
    time to response rate

  8. Anti-tumor activity of ALLO-715 [ Time Frame: up to 24 months ]
    duration of response

  9. Anti-tumor activity of ALLO-715 [ Time Frame: up to 24 months ]
    progression-free survival

  10. Anti-tumor activity of ALLO-715 [ Time Frame: up to 24 months ]
    overall survival

  11. Anti-tumor activity of ALLO-715 [ Time Frame: up to 24 months ]
    minimal residual disease
