Why stopped (as posted): A program evaluation identified that the safety profile and pharmacokinetic (PK) characteristics of the formulation used in all oprozomib studies required further optimization and thus enrollment in OPZ003 was halted during dose-escalation.
Summary
Brief summary (as posted)
The primary objectives of this study included the following: Phase 1b: * To establish the maximum tolerated dose (MTD) of oprozomib given in combination with lenalidomide and dexamethasone (ORd) or with cyclophosphamide and dexamethasone (OCyd) * To evaluate the safety and tolerability of oprozomib and dexamethasone administered in combination with lenalidomide or oral cyclophosphamide Phase 2: * To estimate the antitumor activity of each combination regimen, as measured by overall response rate (ORR) and complete response rate (CRR) * To evaluate the safety and tolerability of each combination regimens, as assessed by the type, incidence, severity and seriousness of adverse events, and abnormalities in selected laboratory analytes

- Oprozomib 150 mg 5/14 + Lenalidomide + Dexamethasone
- description
- Participants received oprozomib 150 mg once daily on days 1 to 5 and days 15 to 19 (5/14 schedule) of each 28-day treatment cycle, in combination with lenalidomide 25 mg on days 1 through 21 and dexamethasone 20 mg/day on days 1, 2, 8, 9, 15, 16, 22, and 23, until progression of disease, unacceptable toxicity, or for 24 cycles, whichever occurred first. After completing 24 cycles of treatment, participants with stable disease or better could have continued on oprozomib with or without dexamethasone pretreatment.
