A Study of Oprozomib, Pomalidomide, and Dexamethasone in Adults With Primary Refractory or Relapsed and Refractory Multiple Myeloma
Phase 1b/3 Multicenter Study of Oprozomib, Pomalidomide, and Dexamethasone in Primary Refractory or Relapsed and Refractory Multiple Myeloma Subjects
The purpose of the Phase 1 part of the study is to determine the maximum tolerated dose and assess the safety, tolerability and activity of oprozomib in combination with pomalidomide and dexamethasone in adults with primary refractory or relapsed and refractory multiple myeloma.
The purpose of the Phase 3 part of the study is to compare the efficacy for adults with primary refractory or relapsed and refractory multiple myeloma who are randomized to either oprozomib or placebo in combination with pomalidomide and dexamethasone.

Descripción detallada
This was a phase 1b/3, multicenter study composed of 2 parts: part 1 was a phase 1b, open-label, dose-escalation and dose-expansion component and part 2 was to have been a phase 3, placebo-controlled, double-blind, randomized component. Part 2 was not conducted.
The Phase 1 dose-escalation portion of the study followed a standard 3 + 3 dose-escalation design. For each of the 2 schedules, groups of 3 to 6 patients were enrolled. The starting doses of oprozomib were 150 and 210 mg in the 5/14 and 2/7 schedules, respectively. The starting dose of pomalidomide was 4 mg in both schedules. As long as < 33% of patients experienced a dose-limiting toxicity (DLT) in a given cohort, the dose of oprozomib was escalated in 30-mg increments for successive cohorts.
Once the recommended dose and schedule for the expansion phase had been selected, additional participants were enrolled in the dose expansion portion of part 1 to continue the evaluation of the safety and efficacy of the regimen and determine the recommended phase 3 dose. Enrollment was halted during the dose expansion phase and part 2 was not conducted.
