Summary

A Study Evaluating Treatment of Multiple Myeloma with Carfilzomib in Combination with Pomalidomide and Dexamethasone

Detailed description

An Open-label, Phase 2 Study Treating Subjects with First or Second Relapse of Multiple Myeloma with Carfilzomib, Pomalidomide, and Dexamethasone (KPd) This trial is designed to estimate the efficacy of a carfilzomib-based triplet in first or second relapse of multiple myeloma for subjects refractory to lenalidomide. The study is an open-label, phase 2 trial. Subjects may receive treatment until progression. Myeloma disease status will be monitored locally for response and progression per International Myeloma Working Group (IMWG) criteria (Kumar et al, 2016) every 28 ± 7 days from cycle 1 day 1 until confirmed progressive disease (PD), death, lost to follow-up, or withdrawal of full consent (whichever occurs first), regardless of cycle duration, dose delays or treatment discontinuation. Subjects with a suspected complete response (CR) or better will have a bone marrow for minimal residual disease (MRD) assessment at 12 and 24 months (± 4 weeks) from start of treatment (unless a MRD assessment was performed within 4 months before planned assessment). Subjects who end study drug(s) without confirmed PD are required to complete disease response assessments and report new anti-myeloma treatment every 28 ± 7 days until first subsequent anti-myeloma treatment, death, lost to follow-up, withdrawal of full consent, confirmed PD, or end of study, whichever occurs first. Subjects who discontinue treatment and either start new anti-myeloma treatment or have PD will enter long-term follow-up every 12 weeks until death or end of study. Approximately one-third of subjects enrolled in the study will be in first relapse and two-thirds in second relapse. This study will enroll adults ≥ 18 years of age with first or second relapse multiple myeloma. Eligible subjects will have relapsed multiple myeloma after receiving 1 or 2 prior lines of therapy. Subjects must be refractory to lenalidomide. Subjects may not have received prior pomalidomide. Prior exposure to a proteasome inhibitor is allowed. Subjects previously exposed to carfilzomib must have responded with at least a partial response to carfilzomib, must not have discontinued carfilzomib due to toxicity, may not have relapsed while receiving or within 60 days of the last dose of carfilzomib, and must have at least a 6 month carfilzomib treatment-free interval since their last dose of carfilzomib. Subjects must have measurable disease per IMWG consensus criteria, Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 to 2, and at least partial response to 1 line of therapy.

Conditions

• Relapsed or Refractory Multiple Myeloma

Interventions

Type	Name	Description
DRUG	Carfilzomib	Carfilzomib will be administered intravenously over 30 ± 5 minutes, on days 1, 8, and 15 (± 2 days) of each 28-day cycle for up to 12 cycles or progression. A dose of 20 mg/m\^2 will be administered on day 1 of cycle 1. All subsequent doses will be 56 mg/m\^2. The frequency of carfilzomib administration will be reduced to day 1 and 15 per cycle starting with cycle 13 and continued until progression or end of study.
DRUG	Dexamethasone	Dexamethasone will be administered at least 30 minutes, but no more than 4 hours prior to carfilzomib on days of carfilzomib administration. Dexamethasone will be administered at a dose of 40 mg on days 1, 8, 15, and 22 of each 28-day cycle up to progression during cycles 1 to 12. Dexamethasone will be administered at a dose of 20 mg on days 1 and 15 of each 28-day cycle up to progression during cycles 13 onward. For subjects more than or equal to 75 years of age, the dose will be 20 mg during cycles 1 through 12 and 10 mg from cycles 13 onward.
DRUG	Pomalidomide	Pomalidomide dose will be 4 mg per day orally on days 1 to 21 of each cycle until progression.
