Official Title ICMJE | Phase 1b Study of REGN5458 (Anti-BCMA x Anti-CD3 Bispecific Antibody) Plus Other Cancer Treatments for Patients With Relapsed/Refractory Multiple Myeloma | ||||||||||||||||||||
Brief Summary | The study is researching an experimental drug called linvoseltamab in combination with other drugs for the treatment of a blood cancer called multiple myeloma. Linvoseltamab has previously been studied as a single agent (without other cancer treatments) in participants with multiple myeloma that returned after prior therapies and needed to be treated again. In the initial study, some participants treated with linvoseltamab had improvement of their myeloma, including complete responses (no evidence of myeloma in their bodies). This study is the first time linvoseltamab will be combined with other cancer therapies. The main goal is to understand if linvoseltamab can be given safely with other cancer treatments, and if so, what dose of linvoseltamab should be used for each combination. The study is looking at several other research questions, including:

Eligibility Criteria ICMJE | General Key Inclusion Criteria:
Cohort Specific Inclusion Criteria: For the below cohorts, each participant must have RRMM with progression following at least 3 lines of therapy, or at least 2 lines of therapy and either prior exposure to at least 1 anti-CD38 antibody, 1 immunomodulatory imide drug (IMiD) and 1 proteasome inhibitor (PI), or double-refractory to 1 PI and 1 IMiD, or the combination of 1 PI and 1 IMiD. Cohort 1: Prior treatment with daratumumab is allowed if previously tolerated. However, participants enrolled in the expansion portion cannot be refractory to an anti-CD38 antibody containing regimen. In addition, all participants must have at least a 6-month washout from prior anti-CD38 antibody therapy. Cohort 2: Prior treatment with carfilzomib is allowed if previously tolerated at the approved full dose. Carfilzomib-refractory participants may enroll in the dose finding portion provided they are triple-class refractory (PI, IMiD, anti-CD38 antibody). However, participants enrolled in the dose expansion portion cannot be refractory to carfilzomib. In addition, all participants must have at least a 6-month washout from prior carfilzomib therapy. Cohort 3: Prior treatment with lenalidomide is allowed if previously tolerated at the approved full dose. However, a participant cannot be refractory to any combination regimen that included 25 mg of lenalidomide. In addition, participants must have at least a 6-month washout from any prior lenalidomide therapy (including maintenance therapy). Cohort 4: Prior treatment with bortezomib is allowed if previously tolerated at the approved full dose. Bortezomib-refractory participants may enroll in the dose finding portion provided they are triple-class refractory (PI, IMiD, anti-CD38 antibody). However, participants enrolled in the dose expansion portion cannot be refractory to bortezomib. In addition, all participants must have at least a 6-month washout from prior bortezomib therapy. Cohort 5: Prior treatment with pomalidomide is allowed if previously tolerated at the approved full dose. Additionally, participants must undergo at least a 6-month washout following prior pomalidomide therapy before enrollment. Cohort 6: Prior treatment with isatuximab is allowed if previously tolerated. Additionally, participants must undergo at least a 3-month washout following prior anti-CD38 antibody therapy before enrollment. Cohort 7 and 8: RRMM with progressive disease and one of the following:
Cohort 9: each participant must have progressive RRMM and the following:
General Key Exclusion Criteria:
Cohort Specific Exclusion Criteria: Cohort 3: 1. Known malabsorption syndrome or pre-existing gastrointestinal (GI) conditions that may impair absorption of lenalidomide (eg, gastric bypass, lap band, or other gastric procedures that would alter absorption); delivery of lenalidomide via nasogastric tube or gastrostomy tube is not allowed. Cohort 4: 1. Peripheral neuropathy grade ≥2 Cohort 5: 1. Known malabsorption syndrome or pre-existing GI conditions that may impair absorption of pomalidomide (eg, gastric bypass, lap band, or other gastric procedures that would alter absorption); delivery of pomalidomide via nasogastric tube or gastrostomy tube is not allowed. Cohort 7:
Cohort 8:
