Study Details

Study Description

Brief Summary

This is a phase II study to evaluate the Outpatient Administration of Teclistamab in Multiple Myeloma Patients

Condition or Disease	Intervention/Treatment	Phase
Multiple Myeloma	Drug: Teclistamab Drug: Tocilizumab	Phase 2

Detailed Description

This is a single-arm, non-randomized, multicenter, prospective study of Teclistamab (TECVAYLI™), in adult patients with RRMM, in the post-marketing setting. Teclistamab (TECVAYLI™), the humanized IgG-4 PAA bispecific antibody, targets the CD3 receptor complex on T cells and BCMA on B-lineage cells.
This study will investigate the use of prophylactic tocilizumab to reduce the incidence and severity of CRS associated with teclistamab administration, to enable administration of the step-up dosing regimen of teclistamab in an outpatient setting.
