Updated Phase 1 Results of Teclistamab, a B-Cell Maturation Antigen (BCMA) x CD3 Bispecific Antibody, in Relapsed and/or Refractory Multiple Myeloma (RRMM)

Background:MM inevitably relapses and becomes refractory to treatment, representing a patient (pt) population with unmet needs. Teclistamab (JNJ-64007957) is a bispecific BCMA x CD3 antibody that induces T cell-mediated cytotoxicity against BCMA-expressing MM cells. Previously presented results from an ongoing study of teclistamab in RRMM (NCT03145181) included a 67% objective response rate [ORR] for the 270 µg/kg dose administered intravenously (iv) (Usmani et al, ASCO 2020 Oral Presentation #100). Here we present updated results and newly available data for subcutaneous (sc) administration.
