Szczegółowy opis

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.

Adverse events (AEs) were graded using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.03 and according to the following: Grade 1 = mild AE, Grade 2 = Moderate AE, Grade 3 = a severe AE, Grade 4 = life-threatening AE, and Grade 5 = death due to AE.

A serious AE is an event that met 1 or more of the following criteria:

  • Death
  • Life-threatening experience
  • Required inpatient hospitalization or prolongation of an existing hospitalization
  • Resulted in persistent or significant disability/incapacity
  • A congenital anomaly birth defect in the offspring of an exposed female subject or offspring of a female partner of a male subject
  • Important medical events that, based upon appropriate medical judgment, jeopardized the participant and may have required medical or surgical intervention to prevent an outcome listed above.

Treatment-related AEs (TRAE) are those considered related to at least 1 study drug by the investigator.
From first dose of any study drug up to 30 days after the last dose; median duration of treatment was 7.6, 28.0, 32.1, 46.3, and 17.4 weeks in each treatment group, respectively.

Overall Response Rate (ORR)
Ramy czasowe: Disease response was assessed every 4 weeks for the first 18 months and then every 8 weeks for the remainder of study treatment; median duration of treatment was 7.6, 28.0, 32.1, 46.3, and 17.4 weeks in each treatment group, respectively.

ORR is defined as the percentage of participants with a best overall response of partial response (PR), very good PR (VGPR), complete response (CR), or stringent CR (sCR) based on the International Myeloma Working Group Uniform Response Criteria.

PR: ≥ 50% reduction of serum M-protein and ≥90% reduction in urine M-protein or to < 200 mg/24 hrs, or a ≥50% decrease in the difference between involved and uninvolved free light chain levels (dFLC). A ≥ 50% decrease in the size of soft tissue plasmacytomas present at baseline.

VGPR: Serum and urine M-protein detectable by immunofixation but not electrophoresis or ≥ 90% decrease in serum M-protein with urine M-protein <100 mg/24 hrs. If disease measurable only by serum FLC (SFLC), ≥ 90% decrease in dFLC.

CR: No immunofixation on serum and urine, disappearance of soft tissue plasmacytomas and <5% plasma cells in bone marrow (BM). Normal SFLC ratio if disease measurable only by SFLC.

sCR: As for CR, and absence of clonal plasma cells in BM.
Disease response was assessed every 4 weeks for the first 18 months and then every 8 weeks for the remainder of study treatment; median duration of treatment was 7.6, 28.0, 32.1, 46.3, and 17.4 weeks in each treatment group, respectively.
Clinical Benefit Rate (CBR)
Ramy czasowe: Disease response was assessed every 4 weeks for the first 18 months and then every 8 weeks for the remainder of study treatment; median duration of treatment was 7.6, 28.0, 32.1, 46.3, and 17.4 weeks in each treatment group, respectively.

Clinical benefit rate is defined as the percentage of participants with a best overall response of minimal response (MR) per modified European Group for Blood and Marrow Transplantation criteria, or PR, VGPR, CR, or sCR as determined by the investigator according to the International Myeloma Working Group Uniform Response Criteria (IMWG-URC).

MR:

  • ≥ 25% but < 49% reduction in serum M-protein and a 50 - 89% reduction in 24-hour urinary M-protein, which still exceeds 200 mg per 24 hours
  • If the serum and urine M-protein were not measurable, a decrease of 25 - 49% in the difference between involved and uninvolved FLC levels was required in place of the M-protein criteria.
  • For patients with nonsecretory myeloma only, 25 - 49% reduction in plasma cells in a bone marrow aspirate and on trephine biopsy, if biopsy is performed
  • 25 - 49% reduction in the size of soft tissue plasmacytomas (by radiography or clinical examination)
Disease response was assessed every 4 weeks for the first 18 months and then every 8 weeks for the remainder of study treatment; median duration of treatment was 7.6, 28.0, 32.1, 46.3, and 17.4 weeks in each treatment group, respectively.
