Brief summary

This is a Phase 2, open-label, multicenter study examining the safety, pharmacokinetics and pharmacodynamics, and best overall response to escalating doses of the proteasome inhibitor NPI-0052 (also known as marizomib) in patients with relapsed or relapsed/refractory multiple myeloma. NPI-0052 is a novel, second generation proteasome inhibitor that prevents the breakdown of proteins involved in signal transduction which blocks growth and survival in cancer cells. The study is a Phase 2 study and is a 2-stage efficacy design in a selected subgroup of patients (Arm C) treated with the recommended phase 2 dose of NPI-0052, as determined in a previously completed Phase 1 study. The study is to evaluate the safety and any preliminary evidence of efficacy of NPI-0052 in multiple myeloma patients who have previously received carfilzomib (PR-171, Kyprolis™) and subsequently had disease progression.
