IPD in RRMM Characterized With Genomic Abnormalities of Adverse Prognostic

Phase 2TerminatedNCT03683277

Intergroupe Francophone du Myelome26 enrolled

Overview

This study is a Multicenter, Open-label, Phase II study of ixazomib, plus Pomalidomide and Dexamethasone regimen (IPD) in RRMM with adverse Genomic Abnormalities.

There is no escalation dose study, the maximum tolerated dose has already been determined in previous phase 1 escalation dose studies. The proposed dose of dexamethasone is considered standard. Patients will receive the IPd regimen until progression. The hypothesis is that this IPd regimen based combination will eventually improve time to disease progression, with no additional toxicity, as compared to other available regimens, in this subgroup of patients with myeloma characterized with a very adverse prognosis. Study design. This trial will study the efficacy and safety of IPd regimen in Relapsed and Refractory Multiple Myeloma with adverse Genomic Abnormalities until progression in 2 separate phases. * Induction phase: 17 cycles - 21-days cycles Ixazomib 3 mg D1, D4, D8 and D11 Pomalidomide 4mg D1 to D14 Dexamethasone 40 mg/d D1, D8 and D15 if patient aged \<75 years Dexamethasone 20 mg/d D1, D8 and D15 if patient aged ≥ 75 years * Maintenance phase: until progression - 28-days cycles Ixazomib 4mg D1, D8 and D15 Pomalidomide 4mg D1 to D21 * It is not planned for the patients to receive autologous stem-cell transplantation as part of the study trial

Outcomes

Primary Outcomes

Time to disease progression (TTP) to IPD in RRMM with adverse Genomic Abnormalities

Time to progression (TTP), defined as time from the first induction cycle to confirmed progressive disease (PD) per the International Myeloma Working Group criteria, or death due to progressive disease, whichever occurs first. It is noted that the events (PD or death due to PD) may include those that occur in the maintenance phase. The analysis will be performed on an Intent-To-Treat (ITT) basis and then per protocol

Time frame: from Cycle 1 Day 1 of Induction phase (each Cycle is 21 days) until documented disease progression or death due to disease progression, whichever came first, assessed through study completion, an average of 18 months

Secondary Outcomes

Incidence of Serious Adverse Events and Adverse Events as assessed by CTCAE version 4.0, dose reduction or modification

A safety Analysis will be performed after the 10th patient enrolled has finished the first cycle of treatment, without any enrollment break. The Independent Data Monitoring Committee (IDMC) will then analyzed the following: * Frequency of Total Serious Adverse Events (SAE) * Frequency of Adverse Events (AEs) Grade 3 or higher * Frequency of dose reductions * Frequency of dose discontinuations Data Monitoring Committee. No enrollment break is planned unless requested by the IDMC. The IDMC will analyze: The interim safety analysis after the10th patient enrolled has finished the first cycle of treatment. Safety review along study if asked by the sponsor.

Time frame: after the 10th patient has completed the first cycle of treatment (Cycle is 21 days), an average of 5 months after the beginning of the study and then every 6 months through study end

Plasma concentrations of ixazomib after twice-weekly dosing in combination with Pomalidomide and Dexamethasone

Sparse Pharmacokinetics samples for the measurement of plasma concentrations of ixazomib will be collected in this study for the purposes of population PK and exposure-response analyses

Time frame: from Cycle 1 Day 1 to Cycle 5 day 1 of Induction phase (each cycle is 21 days)
