Exclusion criteria
Exclusion criteria: 1. Previous exposure to anti-CD38 antibodies or ixazomib. 2. Systemic treatment with or strong CYP3A inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of St. John's wort within 14 days before C1D1. 3. Patient has received anti-myeloma treatment within 2 weeks or 5 pharmacokinetic half-lives of the treatment, whichever is longer, prior to C1D1. The only exception is emergency use of a short course of corticosteroids (equivalent of dexamethasone 40 mg/day for a maximum of 4 days) for palliative treatment before C1D1. 4. Previous allogenic stem cell transplant; or autologous stem cell transplantation (ASCT) within 12 weeks before C1D1. 5. Patient has received radiotherapy within 14 days of C1D1. Urgent localized radiotherapy for Spinal Cord Compression is allowed. 6. History of malignancy (other than MM) within 3 years before C1D1 (exceptions are squamous and basal cell carcinomas of the skin, carcinoma in situ of the cervix or breast, or other non-invasive lesion that in the opinion of the investigator, with concurrence with the Sponsor's medical monitor, is considered cured with minimal risk of recurrence within 3 years). 7. Clinical signs of meningeal involvement of MM. 8. Patient has clinically significant cardiac disease, including: unstable angina or myocardial infarction within 6 months to C1D1, NYHA Class III or IV heart failure, uncontrolled angina, history of severe coronary artery disease, severe uncontrolled ventricular arrhythmias, sick sinus syndrome, or electrocardiographic evidence of acute ischemia or Grade 3 conduction system abnormalities unless patient has a pacemaker, or ECG showing a baseline QT interval as corrected by Fridericia’s formula (QTcF)>470 mesc. 9. Any of the following: a. Known active hepatitis A b. Patient is seropositive for hepatitis B (defined by a positive test for hepatitis B surface antigen [HBsAg]). Subjects with resolved infection (ie, subjects who are HBsAg negative but positive for antibodies to hepatitis B core antigen [anti-HBc] and/or antibodies to hepatitis B surface antigen [anti-HBs]) must be screened using real-time polymerase chain reaction (PCR) measurement of hepatitis B virus (HBV) DNA levels. Those who are PCR positive will be excluded. EXCEPTION: Subjects with serologic findings suggestive of HBV vaccination (anti-HBs positivity as the only serologic marker) AND a known history of prior HBV vaccination, do not need to be tested for HBV DNA by PCR. c. Known to be seropositive for hepatitis C (except in the setting of a sustained virologic response [SVR], defined as aviremia at least 12 weeks after completion of antiviral therapy). 10. Known to be seropositive for human immunodeficiency virus (HIV). 11. Patient has a history of significant neurological, endocrine, gastrointestinal, respiratory, or inflammatory illness or stroke; or COPD requiring >2 hospitalizations in the preceding 12 months from C1D1. 12. Patient has plasma cell leukemia (>2.0 × 109/L circulating plasma cells by standard differential) or Waldenström’s macroglobulinemia or POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes) or amyloidosis. 13. Patient has uncontrolled hypertension or hypertension requiring >2 medications for adequate control within 14 days to C1D1. 14. Patient has uncontrolled diabetes within 14 days to C1D1 or diabetes mellitus with >2 episodes of ketoacidosis in the preceding 12 months from C1D1. 15. Patien

Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this study is to determine the overall response rate (ORR) with the combination of ixazomib, daratumumab and dexamethasone: an ORR inferior to 60% is considered not promising and an 80% as important.;Secondary Objective: • The hematologic and non-hematologic toxicity profile of the combination • Duration of response (DOR) • Time to progression (TTP) • Progression-free survival (PFS) • Overall survival (OS, for the duration of the study) • Time to next therapy (TNT) • MRD negativity using NGFC • Serum bone markers levels (NTX, CTX, bALP, RANKL, OPG, Dkk-1 and SOST) and serum angiogenic cytokines levels (angiogenin, VEGF, angiopoietin-1 and -2);Primary end point(s): The primary endpoint is ORR, which is defined as the percentage of patients that achieve PR or better according to the IMWG criteria ;Timepoint(s) of evaluation of this end point: The whole study duration | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Evaluation of the toxicity profile of the combination, hematologic and non-hematologic. • Progression free survival (PFS), which is defined as the duration from C1D1 to either PD, according to the IMWG criteria [3, 40], or death, whichever occurs first. For patients who have not progressed and are alive, data will be censored at the last disease evaluation before the start of any subsequent anti-myeloma therapy. Relapse from CR by positive immunofixation or trace amount of M-protein is not considered to be PD and is not included in the PFS calculation • Time to disease progression (TTP), defined as the time from C1D1 to the date of first documented evidence of PD, as defined in the IMWG criteria. • Time to next therapy (TNT) defined as the time, in months, from C1D1 to the date to next anti-neoplastic therapy or death from any cause, whichever comes first. For patients who neither start a new anti-neoplastic therapy nor die, survival time will be censored at the date of their last available follow-up date. For a patient who does not have any post-baseline follow-up assessments and who has not died, survival time will be censored at C1D1. • Duration of response will be calculated from the date of initial documentation of a response (CR, VGPR or PR) to the date of first documented evidence of PD, as defined in the IMWG criteria. For patients who have not progressed, data will be censored at the last disease evaluation before the start of any subsequent anti-myeloma therapy. • Overall survival (OS) is measured from C1D1 to the date of the patient’s death. If the patient is alive or the vital status is unknown at the time of the analysis, then the patient’s data will be censored at the date the patient was last known to be alive. • Minimal residual disease (MRD) negativity rate, defined as the proportion of patients who achieve a negative result of MRD. Patients without MRD assessment will be considered as having MRD-positive results. • Level | — |
