简要总结
This randomized phase I/II trial studies the side effects and best dose of pomalidomide and ixazomib when given together with dexamethasone and to see how well pomalidomide and dexamethasone with or without ixazomib works in treating patients with multiple myeloma that has come back. Biological therapies, such as pomalidomide and dexamethasone, may stimulate the immune system in different ways and stop cancer cells from growing. Ixazomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. It is not yet known whether pomalidomide and dexamethasone are more effective with or without ixazomib in treating multiple myeloma.
详细描述
PRIMARY OBJECTIVES:
I. To establish the maximum tolerated dose (MTD) for combination therapy pomalidomide/dexamethasone/ixazomib. (Phase I) II. To assess whether the combination of pomalidomide/dexamethasone/ixazomib improves progression-free survival (PFS) relative to pomalidomide/dexamethasone. (Phase II)
SECONDARY OBJECTIVES:
I. To determine dose-limiting toxicities (DLTs). (Phase I) II. To analyze type and grade of all serious adverse events (SAEs). (Phase I) III. To analyze type and grade of all adverse events (AEs). (Phase I) IV. To analyze the reason for and incidence of dose modifications/omissions/delays. (Phase I) V. To assess preliminary evidence of clinical efficacy. (Phase I) VI. To assess whether the overall response rate (ORR), partial response (PR), very good partial response (VGPR), complete response (CR) or stringent CR (sCR) rate differ with respect to treatment regimen. (Phase II) VII. To assess the clinical benefit rate (CBR: minimal response [MR] + ORR) for pomalidomide/dexamethasone/ixazomib compared to pomalidomide/dexamethasone. (Phase II) VIII. To assess the disease control rate (DCR: stable disease [SD] + CBR) for pomalidomide/dexamethasone/ixazomib compared to pomalidomide/dexamethasone. (Phase II) IX. For those patients achieving a PR or better, we will assess whether the combination of pomalidomide/dexamethasone/ixazomib increases the duration of response (DOR) compared to pomalidomide/dexamethasone. (Phase II) X. To assess whether the combination of pomalidomide/dexamethasone/ixazomib improves overall survival (OS) compared to those taking pomalidomide/dexamethasone alone. (Phase II) XI. To assess time to next treatment (TNT) for patients taking pomalidomide/dexamethasone/ixazomib compared to those on pomalidomide/dexamethasone. (Phase II) XII. To evaluate the safety of pomalidomide/dexamethasone/ixazomib compared with pomalidomide/dexamethasone. (Phase II) XIII. For patients on the pomalidomide/dexamethasone arm who opt to cross-over to the pomalidomide/dexamethasone/ixazomib arm, assessment of response rate (ORR, CBR, DCR), DOR, TNT, PFS and OS will be evaluated from date of cross-over. (Phase II) XIV. To determine if baseline level of perceived fatigue and overall quality of life (QOL) is associated with OS. (Phase II)
OUTLINE: This is a phase I, dose-escalation study of pomalidomide and ixazomib followed by a phase II study.

研究组 & 干预措施
Arm I (pomalidomide, dexamethasone)
Patients receive pomalidomide PO QD on days 1-21 and dexamethasone PO QD on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients achieving disease progression may cross over to Arm II.

主要结局
Maximum Tolerated Dose (MTD) of Pomalidomide and Ixazomib, Determined According to Incidence of Dose Limiting Toxicity (DLT) Graded Using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0 (Phase I)
时间窗: 28 days
For this protocol, dose-limiting toxicity (DLT) will be defined by the following adverse events at least possibly related to study therapy: Grade 3 or higher non-hematologic toxicity, with the following exceptions: Alopecia is not expected but would not be considered a DLT. Nausea, vomiting and diarrhea will only be considered a DLT if it cannot be adequately managed with optimal supportive care. Grade 3 or 4 hyperglycemia due to dexamethasone will only be considered a DLT if it cannot be controlled with appropriate therapy Grade 4 hematologic toxicity, with the following exceptions: Grade 4 lymphopenia is expected with this regimen and will not be construed as a DLT. Grade 4 neutropenia will only be considered a DLT if it lasts longer than 7 days despite appropriate supportive care. Grade 4 thrombocytopenia will only be considered a DLT if it lasts longer than 7 days or is associated with greater then or equal to grade 3 bleeding event
Progression Free Survival (PFS) (Phase II)
时间窗: 3 years
progression-free survival (PFS), defined as the time from randomization to the date the International Myeloma Working Group (IMWG) criteria for disease progression is met. If a patient initiates another anti-cancer treatment prior to disease progression, they will be censored at the date of initiation of this treatment. Patients will be randomized to treatment using the Pocock-Simon algorithm balancing the distribution of the following stratification factors between the two treatment arms: 1) ISS 1-2 disease vs. ISS 3 disease (current ISS stage based off screening beta 2 microglobulin and albumin) 2) High risk cytogenetics features: yes vs. no High risk cytogenetics features include: del(1p), gain of 1q, t(4;14), t(14;16), t(14; 20), del(17p) 3) Prior treatment with a proteasome inhibitor: yes vs. no
