ALLO-715, an off-the-shelf chimeric antigen receptor (CAR) T-cell therapy that targets B-cell maturation antigen (BCMA), elicited responses in heavily pretreated patients with relapsed/refractory multiple myeloma in early findings from a first-in-human study presented at the 2020 ASH Meeting.

The therapy generated responses in 6 of 10 patients (60%), including a very good partial-plus response (VGPR+) in 4 patients (40%), who were treated with ALLO-715 at a dose of 320 x 10⁶ CAR cells plus a lymphodepleting regimen that included ALLO-647, an anti-CD52 monoclonal antibody, during the ongoing phase 1 UNIVERSAL study (NCT04093596).
