Phase I/II Study of SLAMF7 FPBMC/CS-1 FPBMC in Relapsed/Refractory Multiple Myeloma

Withdrawn before enrolling · Phase 1/Phase 2

Conditions studied: Multiple Myeloma

In brief

The purpose of this study is to understand the safety and estimate the efficacy of combining anti-CD3 x anti-SLAMF7 bispecific antibody fresh peripheral blood mononuclear cells (SLAMF7 FPBMC/CS1 FPBMC) for patients with relapsed and/or refractory multiple myeloma. Patients receive 8 weekly doses and then 8 more doses every 2 weeks of SLAMF7 FPBMC by intravenous infusion.
