A Phase 2 Study of Isatuximab in Combination With Pomalidomide and Dexamethasone in MM Patients Who Received One Prior Line of Therapy Containing Lenalidomide and a Proteasome Inhibitor

This is an investigator-initiated (IIS), phase 2, prospective, open-label, multinational study, designed to be conducted in approximately 14 sites. Eligible patients will initially receive six 28-day cycles of isatuximab, pomalidomide, and low-dose dexamethasone. Following this phase: Patients who achieve ≥VGPR will be randomized in a 1:1 ratio to receive isatuximab, given either Q2W or once monthly, plus pomalidomide and low-dose dexamethasone. Patients with \<VGPR will continue treatment with isatuximab Q2W, pomalidomide, and low-dose dexamethasone. The study will last for 42 months (recruitment and follow-up period), starting from the date of the first patient in (FPI) to the date of the last patient last visit (LPLV). Core study procedures consist of baseline and post-baseline safety and disease evaluations, including physical examination, hematologic/clinical chemistry tests, radiologic assessments, bone marrow evaluations, and blood/urine M-protein assessments. Patients will be allowed to continue treatment until disease progression, death, unacceptable AEs, lost to follow-up, or consent withdrawal.
