Eligibility
Inclusion criteria
Inclusion criteria: •Subject has documented diagnosis of MM and measurable disease, defined as: —M-protein = 0.5 g/dL by serum protein electrophoresis (sPEP), or = 200 mg/24-hour urine collection by urine protein electrophoresis (uPEP) or, —For subjects without measurable disease in sPEP or uPEP: serum free light chain (sFLC) levels > 100 mg/L (10 mg/dL) involved light chain and an abnormal kappa/lambda FLC ratio •Subject has received 1 to 3 prior anti-myeloma lines of therapy •Subject must have received prior treatment with a lenalidomide containing regimen. For country-specific requirements, see APPENDIX I. •Subject achieved a minimal response [MR] or better to at least 1 prior antimyeloma therapy •Subject must have documented disease progression during or after their last antimyeloma regimen •Subject has an Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1 or 2. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 418 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 532
Exclusion criteria
Exclusion criteria: •Subject has had prior treatment with mezigdomide or pomalidomide •Subject has had progression during treatment or within 60 days of the last dose of a proteasome inhibitor, except as noted below: a. Subjects who progressed while being treated with, or within 60 days of last dose of bortezomib maintenance given once every 2 weeks or less are not excluded. •Subject discontinued prior treatment with bortezomib due to toxicity •Any of the following laboratory abnormalities: —ANC 13.5 mg/dL (> 3.4 mmol/L) —AST or ALT > 2.5 × ULN —Serum total bilirubin > 1.5 × ULN, or for subjects with documented Gilbert’s syndrome > 3.0 mg/dL
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the progression-free survival (PFS) of mezigdomide, bortezomib and dexamethasone (MeziVd) to that of pomalidomide, bortezomib and dexamethasone (PVd) in subjects with relapsed or refractory multiple myeloma (RRMM);Secondary Objective: - In Stage 1, to determine the dose of mezigdomide in combination with bortezomib and dexamethasone to continue in Stage 2 of the study - In Stage 1, to determine the plasma concentrations of mezigdomide in combination with bortezomib and dexamethasone - To compare overall survival (OS) between MeziVd and PVd in subjects with RRMM - To evaluate additional efficacy parameters in subjects with RRMM treated with MeziVd compared to PVd - To evaluate minimal residual disease (MRD) negativity rate in subjects treated with MeziVd compared to those treated with PVd - To evaluate safety of MeziVd compared to PVd in subjects with RRMM - In subjects randomized to Stage 2, to evaluate cancer-related symptoms and healthrelated quality of life (HRQoL) using the European Organization for Research and Treatment of Cancer - Quality of Life C30 questionnaire (EORTC QLQ-C30) and the European Quality of Life Multiple Myeloma Module (EORTC QLQ-MY20) in subjects treated with MeziVd compared to PVd;Primary end point(s): Progression free Survival (PFS) ;Timepoint(s) of evaluation of this end point: 43 months | — |
