description
DLTs were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03. A DLT is defined as any of the following treatment-related events: * Any ≥ Grade 3 nonhematologic toxicity with the following conditions: * ≥ Grade 3 nausea, vomiting, diarrhea, or constipation only if for \> 7 days despite optimal supportive care * Asymptomatic Grade 3 hypophosphatemia, Grade 3 hyperglycemia or toxicity solely due to dexamethasone, ≥ Grade 3 rash attributed to lenalidomide, and Grade 3 fatigue for \< 14 days were not considered DLTs * Grade 4 neutropenia: absolute neutrophil count (ANC) \< 0.5 × 10\^9/L lasting ≥ 7 days, despite myeloid growth factor support * Febrile neutropenia * Grade 4 thrombocytopenia for ≥ 7 days or \< 7 days with ≥ Grade 2 clinically significant bleeding or \< 10,000 platelets requiring platelet transfusion, or Grade ≥ 3 with clinically significant bleeding or requiring platelet transfusion.

Adverse events (AEs) were graded using 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 are those considered related to at least 1 study drug by the investigator.

description
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 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 SFLC, ≥ 90% decrease in the difference between involved and uninvolved FLC levels (dFLC). CR: No immunofixation on serum and urine, disappearance of soft tissue plasmacytomas and \<5% plasma cells in BM. Normal serum free light chain (SFLC) ratio if disease measurable only by SFLC. sCR: As for CR, and absence of clonal plasma cells in bone marrow (BM).
measure
Overall Response Rate (ORR)
time Frame
Disease response was assessed every 4 weeks for 24 cycles then every 8 weeks until end of treatment; median duration of treatment at the analysis cutoff date of 18 July 2016 was 29.1, 12.4, 11.3, 66.6, 7.8 and 46.4 weeks in each group, respectively
description
Duration of response was defined as the time from first evidence of partial response (PR) or better to confirmation of disease progression or death due to any cause. Median DOR was estimated using Kaplan-Meier methods. Participants who started a new anticancer therapy before documentation of disease progression or death, or who were alive without documentation of disease progression before the data cut-off date or who died or had disease progression immediately after more than 1 consecutively missed disease assessment visit were censored at the date of last disease assessment.

description
Progression-free survival is defined as the time from the start of treatment to disease progression or death (due to any cause), whichever occurred first. Median PFS was estimated using Kaplan-Meier methods. Participants who started a new anticancer therapy before documentation of disease progression or death, or who were alive without documentation of disease progression before the data cut-off date or who died or had disease progression immediately after more than 1 consecutively missed disease assessment visit were censored at the date of last disease assessment.

Full study description

brief Summary: 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
detailed Description: Phase 1b used a standard 3 + 3 dose-escalation scheme to determine the MTD. For each combination regimen, oprozomib doses were to be escalated in sequential cohorts of 3 participants with expansion to up to 6 participants if a dose-limiting toxicity (DLT) was observed in 1 of the first 3 participants. The doses of lenalidomide, cyclophosphamide, and dexamethasone were to remain fixed in all dose cohorts. The phase 2 portion of the study was to include up to 35 additional participants in each of the 2 combination regimens, treated at the recommended phase 2 dose (RP2D) of oprozomib that was identified during the phase 1b portion of the study in order to better characterize safety and tolerability, and antimyeloma activity. This study was stopped by sponsor decision during the dose escalation in phase 1b prior to initiation of phase 2.
