Brief Summary:

Phase 1b:

  • To establish the maximum tolerated dose (MTD) of oprozomib and dexamethasone administered in combination with lenalidomide or oral cyclophosphamide
  • To evaluate the safety and tolerability of oprozomib and dexamethasone administered in combination with lenalidomide or oral cyclophosphamide

Phase 2:

  • To estimate the overall response rate (ORR) and complete response rate (CRR)
  • To evaluate the safety and tolerability of oprozomib and dexamethasone administered in combination with lenalidomide or oral cyclophosphamide

Secondary Objectives:

  • To evaluate population pharmacokinetic (PK) parameter estimates of oprozomib and variability in these estimates when administered in combination with dexamethasone and lenalidomide or oral cyclophosphamide
  • To estimate the duration of response (DOR)
  • To estimate progression-free survival (PFS)

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Maximum Tolerated Dose (MTD) [ Time Frame: 6 months ]
    For each dosing schedule, the MTD will be defined as the highest dose at which a DLT is observed in fewer than 2 of 6 patients. DLT is defined as any of the following treatment-related events occurring in the first 28 days of treatment.

  2. Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: 36 months ]
    Safety and tolerability of oprozomib and dexamethasone administered in combination with lenalidomide or oral cyclophosphamide, as defined by the type, incidence, severity, and outcome of Adverse Events (AEs).

  3. Overall Response Rate (ORR) [ Time Frame: 14 months ]
    The antitumor activity of oprozomib and dexamethasone administered in combination with lenalidomide or oral cyclophosphamide, as measured by overall response rate (ORR).

  4. Complete Response Rate (CRR) [ Time Frame: 17 months ]
    The antitumor activity of oprozomib and dexamethasone administered in combination with lenalidomide or oral cyclophosphamide, as measured by complete response rate (CRR).


Secondary Outcome Measures :
  1. Population Pharmacokinetic (PK) Parameters - Apparent Clearance [ Time Frame: 18 months ]
    The Apparent Clearance is defined as the amount of drug administered (dose) divided by the plasma concentration-time curve (AUC) of oprozomib and its metabolites at various time points.

  2. Population Pharmacokinetic (PK) Parameters - Volume of Distribution [ Time Frame: 18 months ]
    The Volume of Distribution is defined as the amount of oprozomib administered (dose) divided by initial oprozomib plasma concentration.

  3. Duration of Response (DOR) [ Time Frame: 42 months ]
    Duration of Response is defined as the time from first evidence of partial response (PR) or better to confirmation of disease progression or death due to any cause.

  4. Progression-Free Survival (PFS) [ Time Frame: 42 months ]
    Progression-Free Survival is defined as the time from the start of treatment to disease progression or death (due to any cause), whichever comes first.
