If previously treated with bortezomib (alone or in combination), progression during treatment 2. If previously treated with a lenalidomide and dexamethasone (len/dex) combination: - Progression during the first 3 months of initiating treatment - Any progression during treatment if the len/dex combination was the subject's most recent line of therapy 3. Discontinuation of previous lenalidomide or dexamethasone due to intolerance; subjects intolerant to bortezomib are not excluded 4. Prior carfilzomib treatment 5.

Significant neuropathy (Grades 3-4, or Grade 2 with pain) within 14 days prior to randomization 20. Known history of allergy to Captisol® (a cyclodextrin derivative used to solubilize carfilzomib) 21. Contraindication to any of the required concomitant drugs or supportive treatments, including hypersensitivity to all anticoagulation and antiplatelet options, antiviral drugs, or intolerance to hydration due to preexisting pulmonary or cardiac impairment 22. Ongoing graft-vs-host disease 23. Subjects with pleural effusions requiring thoracentesis or ascites requiring paracentesis within 14 days prior to randomization 24.

Additional Information

Official title A Randomized, Multicenter, Phase 3 Study Comparing Carfilzomib, Lenalidomide, and Dexamethasone (CRd) vs Lenalidomide and Dexamethasone (Rd) in Subjects With Relapsed Multiple Myeloma
Principal investigator A. Keith Stewart, MD
Description This is a Phase 3, randomized, open-label, multicenter study comparing two treatment regimens for subjects with relapsed multiple myeloma. Eligible subjects will be randomized in a 1:1 ratio to receive either the control Rd or CRd. Randomization will be stratified by β2 microglobulin levels (< vs ≥ 2.5 mg/L), prior bortezomib (no vs yes), and prior lenalidomide (no vs yes). Subjects will receive the treatment determined by randomization in 28-day cycles until disease progression or unacceptable toxicity (whichever occurs first). The primary endpoint of this Phase 3 study is progression-free survival.
