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.
Presence - at diagnosis or at relapse - of one of the following adverse genomic abnormalities determined using Interphase fluorescence in situ hybridization and Single nucleotide polymorphism (FISH/SNP) techniques at a significant rate validated centrally by Pr AVET - LOISEAU:
Must have a Progressive Multiple Myeloma (MM) according to IMWG consensus recommendations for multiple myeloma treatment response criteria (DURIE 2007, RAJKUMAR 2011) :
Must have a measurable disease as defined by the following:
Patients must meet the following clinical laboratory criteria:
Female patients who:
Male patients, even if surgically sterilized (i.e., status post-vasectomy), must agree to one of the following:
Patients agree:
Exclusion Criteria:
Prior local irradiation within two weeks before first dose*
*However, an exception (that is patients allowed to remain in the treatment phase of the study) is made for radiation therapy to a pathological fracture site to enhance bone healing or to treat post-fracture pain that is refractory to narcotic analgesics because pathologic bone fractures do not by themselves fulfill a criterion for disease progression.)

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
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.
