A Phase 1 Multicenter Study of KITE-585, an Autologous Anti-BCMA CAR T-Cell Therapy, in Subjects With Relapsed/Refractory Multiple Myeloma

The primary objective of the study is to evaluate the safety and tolerability of KITE-585, an autologous engineered chimeric antigen receptor (CAR) T-cell product targeting a protein commonly found on myeloma cells called B-cell maturation antigen (BCMA), as measured by the incidence of dose-limiting toxicities (DLTs). Participants will be given a 3 day course of conditioning chemotherapy followed by a single infusion of KITE-585.

Participants with relapsed/refractory multiple myeloma can participate if all eligibility criteria are met. Tests required to determine eligibility include disease assessments, a physical exam, ECG and echocardiogram of the heart, brain MRI, and blood draws. Eligible participants have white blood cells collected by leukapheresis. These cells are genetically modified to make the experimental treatment KITE-585. Participants receive conditioning chemotherapy prior to the KITE-585 infusion. After the KITE-585 infusion, participants will be followed for side effects and effect of KITE-585 on their myeloma. Study procedures may be performed while hospitalized and/or in the outpatient setting.
