Phase 3 Study Comparing Mezigdomide, Bortezomib and Dexamethasone Versus Pomalidomide, Bortezomib and Dexamethasone in Adults with Relapsed or Refractory Multiple Myeloma

What this Trial Is About

This trial investigates the effectiveness and safety of two treatment combinations for people with relapsed or refractory multiple myeloma who have received one to three prior treatments and were previously treated with lenalidomide. It compares mezigdomide, bortezomib, and dexamethasone MeziVd against pomalidomide, bortezomib, and dexamethasone PVd to see which is better for this condition. The study is a Phase 3, randomized, open-label trial sponsored by Celgene. Participants receive either the MeziVd combination or the PVd combination, with specified doses given on certain days according to the study plan. These treatments are given as drugs, and participants are randomly assigned to one of these two groups to compare their effects. The study will continue for up to approximately five years to evaluate long-term outcomes. During the study, participants will be monitored regularly through various assessments including measuring disease progression, survival, response to treatment, and quality of life using specific questionnaires EORTC QLQ-C30 and QLQ-MY20. Blood samples may be checked for drug levels, and adverse events will be tracked. The main focus is progression-free survival, measured from randomization until disease worsening or death. Participants health and responses will be followed for up to five years, with ongoing visits and evaluations throughout this period.
