Participants With Dose-Limiting Toxicities (DLT)
Periodo de tiempo: Day 1 to Day 14 (Cycle 1) for continous dosing and Day 15 to Day 28 (Cycle 2) for step-up dosing
|
Toxicities (graded per the Common Terminology Criteria for Adverse Events v 4.03) were considered DLTs if judged by the investigator to be related to oprozomib and occurred in the first 14 days of treatment, with treatment at the dose to be studied (i.e., Cycle 1 for continuous dosing or Cycle 2 for step-up dosing). A DLT was categorized as nonhematologic or hematologic. Examples include:
|
Day 1 to Day 14 (Cycle 1) for continous dosing and Day 15 to Day 28 (Cycle 2) for step-up dosing
|
|
Participants With Treatment-Emergent Adverse Events (TEAEs) During Phase 1b and 2
Periodo de tiempo: Day 1 up to Week 282
|
AE defined as any untoward medical occurrence in a clinical trial participant. Treatment-emergent adverse events were defined as adverse events that start on or after the first day of study treatment and within 30 days of the last day of study treatment. An adverse event that was present before the first administration of study treatment and subsequently worsens in severity during treatment was also considered to be treatment-emergent. Serious AE defined as AE that is fatal, life threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or other significant medical hazard. Severity of AEs assessed according to Common Terminology Criteria for Adverse Events (CTCAE, v4.03) based on the general guideline: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4: Life-threatening or disabling; Grade 5: Death related to AE.

Kaplan-Meier Estimates for Duration of Response (DOR) as Assessed by Investigator During Phase 2
Periodo de tiempo: Day 1 up to 13.16 months
|
Duration of response was defined as the time from first evidence of partial response (PR) or better (i.e.
best overall response) to confirmation of disease progression or death due to any cause.
Durations were calculated for responders only.
Medians and percentiles were estimated using the Kaplan-Meier method.
95% confidence intervals for medians and percentiles were estimated using the method by Klein and Moeschberger (1997) with log-log transformation.

Kaplan-Meier Estimates for Progression-free Survival (PFS) as Assessed by Investigator During Phase 2
Periodo de tiempo: Day 1 up to 14.1 months
|
Progression-free survival (PFS) was defined as number of months between start of treatment and first evidence of documented disease progression or death (due to any cause), whichever occurs first. Disease progression was determined using IMWG-URC per investigator. The duration of PFS was right-censored for participants who met 1 of the following conditions:

Day 1 up to 14.1 months

Kaplan-Meier Estimate for Time to Progression (TTP) as Assessed by Investigator During Phase 2
Periodo de tiempo: Day 1 up to 14.1 months
|
Time to progression (TTP) was defined as the number of months between the start of treatment to the first documentation of disease progression. Disease progression was determined using IMWG-URC as assessed by the investigator. The same censoring rules, except for death, as in analysis of PFS were applied in the calculation of TTP. Participants who died prior to progressive disease were censored at the date of last evaluable response assessment. |
