Isatuximab in Combination With Cemiplimab in Relapsed/Refractory Multiple Myeloma (RRMM) Patients

• Status: Active, not recruiting
• Trial end date: 2022-06-30
• Target enrollment: 0
• Participant gender: All

Summary

Primary Objectives:

• To evaluate the safety and tolerability of the combination of isatuximab (also known as SAR650984) and cemiplimab (also known as REGN2810) in patients with relapse/refractory multiple myeloma.

• To compare the overall response of the combination of isatuximab and cemiplimab versus isatuximab alone in patients with RRMM based on International Myeloma Working Group (IMWG) criteria.

Secondary Objectives:

• To evaluate the efficacy as assessed by clinical benefit rate (CBR), duration of response (DOR), time to response (TTR), progression free survival (PFS), and overall survival (OS).

• To assess the pharmacokinetics (PK) of isatuximab and cemiplimab when given in combination.

• To assess the immunogenicity of isatuximab and cemiplimab when given in combination.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Sanofi
• Treatments: Cemiplimab

Criteria

Inclusion criteria:

• Patients must have a known diagnosis of multiple myeloma with evidence of measurable disease, as defined below:

• Serum M-protein ≥1 g/dL (≥0.5 g/dL in case of immunoglobulin A [IgA] disease), AND/OR

• Urine M-protein ≥200 mg/24 hours, OR

• In the absence of measurable M-protein, serum immunoglobulin free light chain ≥10 mg/dL, and abnormal serum immunoglobulin kappa lambda free light chain ratio (<0.26 or >1.65).

• Patients must have received prior treatment with an immunomodulatory drug (IMiD) (for ≥2 cycles or ≥2 months of treatment) and a proteasome inhibitor (PI) (for ≥2 cycles or ≥2 months of treatment).

• Patients must have received at least 3 prior lines of therapy (Note: Induction therapy and stem cell transplant ± maintenance will be considered as one line).

• Patient must have achieved MR or better with any anti-myeloma therapy (ie, primary refractory disease is not eligible).

Exclusion criteria:

• Prior exposure to isatuximab or participated clinical studies with isatuximab.

• Prior exposure to any agent (approved or investigational) that blocks the programmed cell death-1 (PD-1)/PD-L1 pathway.

• Evidence of other immune related disease/conditions.

• History of non-infectious pneumonitis requiring steroids or current pneumonitis; history of the thoracic radiation.

• Has received a live-virus vaccination within 30 days of planned treatment start. Seasonal flu vaccines that do not contain live virus are permitted.

• Has allogenic haemopoietic stem cell (HSC) transplant.

• Prior treatment with idelalisib (a PI3K inhibitor).

• Eastern Cooperative Oncology Group (ECOG) performance status (PS) >2.

• Poor bone marrow reserve.

• Poor organ function.
