Informations complémentaires
Schéma : This is a multicenter, Phase 3, randomized, open-label study comparing daratumumab, pomalidomide and low-dose dexamethasone (DaraPomDex) with pomalidomide and low-dose dexamethasone (PomDex) in subjects with relapsed or refractory Multiple Myeloma who have received at least 1 prior treatment regimen with both lenalidomide and a proteasome inhibitor and have demonstrated disease progression. Subjects will be randomized in a 1:1 ratio to receive either DaraPomDex or PomDex. The original design of this study was to treat subjects with daratumumab for intravenous (IV) infusion (Dara IV); however, as of Amendment 1, all new subjects will be dosed subcutaneously with daratumumab co-formulated with recombinant human hyaluronidase rHuPH20 (hereafter referred to as Dara SC). Subjects who already began treatment with Dara IV (ie, prior to Amendment 1) will have the option to switch to Dara SC on Day 1 of any cycle starting with Cycle 3 or later for the remainder of their participation in the study, and they will be counted toward the total of 302 subjects. Subjects will receive treatment until disease progression or unacceptable toxicity. Drug administration and follow-up visits will occur more frequently for early cycles (e.g., weekly or bi-weekly). Disease evaluations will occur every cycle and consist mainly of measurements of myeloma proteins. Subject safety will be assessed throughout the study. The primary endpoint will be progression-free survival (PFS). Study end is anticipated at approximately 5 years after the last subject is randomized.

Study arms:
- Experimental: Daratumumab+Pomalidomide+Dexamethasone
Daratumumab at a dose of 16 mg/kg administered as an IV infusion (Dara IV) or 1800 mg subcutaneously (Dara SC) at weekly intervals (QW) for 8 weeks, then every 2 weeks (Q2W) for an additional 16 weeks, then every 4 weeks (Q4W) thereafter. Pomalidomide 4 mg orally (PO) on Days 1 through 21 of each 28-day cycle Dexamethasone 40 mg (20 mg for patients ≥75 years of age) orally, once daily on Days 1, 8, 15, and 22 of each 28-day treatment cycle

- Reproductive Status
a. Women of childbearing potential (WOCBP) must have 2 negative serum or urine pregnancy tests, one 10-14 days prior to start of study treatment and one 24 hours prior to the start of study treatment. Females are not of reproductive potential if they have been in natural menopause for at least 24 consecutive months, or have had a hysterectomy and/or bilateral oophorectomy.
b. Women must not be breastfeeding.
c. WOCBP must agree to follow instructions for methods of contraception for 4 weeks before the start of study treatment, for the duration of study treatment, and for 3 months after cessation of daratumumab or 4 weeks after cessation of pomalidomide, whichever is longer.
d. Males who are sexually active must always use a latex or synthetic condom during any sexual contact with females of reproductive potential, even if they have undergone a successful vasectomy. They must also agree to follow instructions for methods of contraception for 4 weeks before the start of study treatment, for the duration of study treatment, and for a total of 3 months post-treatment completion.
e. Male subjects must not donate sperm for up to 90 days post-treatment completion.

Highly effective methods of contraception have a failure rate of < 1% when used consistently and correctly. Subjects must agree to the use of 2 methods of contraception, with 1 method being highly effective and the other method being additionally effective.
Because of the embryo-fetal risk of pomalidomide, all subjects must adhere to the pomalidomide pregnancy prevention program applicable in their region. Investigators should comply with the local label for pomalidomide for specific details of the program.
Critères de non-inclusion : - Previous therapy with any anti-CD38 monoclonal antibody.
