| E.2.1 | Main objective of the trial | 
| compare efficacy of 56 mg/m2 carfilzomib administered
 once-weekly in combination with
 lenalidomide and dexamethasone
 (KRd 56 mg/m2) to
 27 mg/m2 carfilzomib administered
 twice-weekly in combination with
 lenalidomide and dexamethasone
 (KRd 27 mg/m2) in subjects with
 RRMM with 1 to 3 prior lines of
 therapy
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| *compare progression-free survival (PFS) between treatment arms
 *compare patient-reported
 convenience with carfilzomib-dosing
 schedule between treatment arms
 |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| *Subject has provided informed consent prior to initiation of any study-specific activities or procedures or subject’s legally acceptable representative has
 provided informed consent prior to any study-specific activities/procedures being

 Investigator, may compromise the ability of the subject to give written informed
 consent.
 *Males or females ≥ 18 years of age.
 *Documented relapse or progressive multiple myeloma on or after any treatment
 (subjects refractory to the most recent line of therapy are eligible, unless last
 treatment contained PI or lenalidomide and dexamethasone).

 *Subjects must have received at least 1 but not more than 3 prior lines of therapy
 for multiple myeloma (induction therapy followed by stem cell transplant and
 consolidation maintenance therapy will be considered as 1 line of therapy). See
 Section 12.8 for guidelines for documenting prior treatment.
 *Prior therapy with a PI or lenalidomide and dexamethasone is allowed, as long
 as the patient had at least a PR to most recent therapy with PI or lenalidomide
 and dexamethasone, was not removed due to toxicity, and will have at least a
 6-month PI or lenalidomide and dexamethasone treatment-free interval from last
 dose received until first study treatment. (Patients may receive maintenance
 therapy with lenalidomide during this 6-month PI or lenalidomide and
 dexamethasone treatment-free interval).
 *Previous treatment with a lenalidomide and dexamethasone containing regimen
 is allowed, as long as the subject did not progress during the first 3 months after
 initiating lenalidomide and dexamethasone containing therapy.
