Multiple myeloma is an incurable hematological malignancy that affects older patients. Currently, despite recent progress, the disease relapses more or less quickly after initial treatment and requires the resumption of treatment with new drugs associated with cortisone, whose side effects are important. The investigators propose to conduct a phase 2 testing the combination ixazomib - daratumumab without dexamethasone.

One or two line(s) of prior therapies
Patients must have Progressive Disease as defined by the IMWG as one of the following (Kumar, 2016): Increase of 25% from lowest response value in any one or more of the following
Serum M-component (absolute increase must be 0.5 g/100 ml) and/or Urine M-component (absolute increase must be 200 mg per 24 h) and/or
Only in patients without measurable serum and urine M-protein levels: the difference between involved and uninvolved FLC levels (absolute increase must be > 10 mg/l)
Bone marrow plasma cell percentage (absolute % must be 10%)
Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas
Development of hypercalcemia (corrected serum calcium > 11.5 mg/100 ml) that can be attributed solely to the plasma cell proliferative disorder
Patients must have undergone prior treatment with VMP or Rd
They must have received at least two cycles of therapy
Either at diagnosis or relapse
Patients must have a clearly detectable and quantifiable monoclonal M-component value: IgG (serum M-component > 10g/l) ; IgA (serum M-component > 5g/l) ; IgD (serum M-component > 0.5g/l); Light chain (serum M-component >1g/l or Bence Jones > 200 mg/24H) In patients without measurable serum and urine M-protein levels when the absolute serum Free Light chain (sFLC) is 100 mg/l and an abnormal sFLC K/ ratio (<0.26 and >1.65) is found (Dispenzieri, 2008)
Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2
Adequate bone marrow function within 5 days prior to 1st drug intake (cycle1, day 1, C1D1), without transfusion nor growth factor support within 5 days prior to 1st drug intake, defined as: Absolute neutrophils 1000/mm3 ; Platelets 50000/mm3 ; Haemoglobin 8.5g/dl
Adequate organ function defined as: Serum creatinine clearance (MDRD formula) 30 ml/min ; Serum SGOT or SGPT < 3.0 X upper limit of normal (ULN) ; Serum total bilirubin < 1.5 ULN
Wash out period of at least 2 weeks from previous antitumor therapy or any investigational treatment or 5 half-lives from previous antibodies
Women who are partners of men and of childbearing potential must be practicing one of the following methods of birth control: subcutaneous hormonal implant, levonorgestrel releasing intra-uterine system, medroxyprogesterone acetate depot, tubal sterilization, ovulation inhibitory progesterone only pills, or sexual intercourse with a vasectomized male partner (vasectomy must be confirmed by 2 negative semen analyses). Or women will commit to absolute and continuous abstinence confirmed to her physician on a monthly basis. Childbearing potential. Contraception will start during therapy including dose interruptions, for 4 months after discontinuation of Ixazomib and Daratumumab
Criteria for women of childbearing potential
This protocol defines a female of childbearing potential as a sexually mature
woman who
has not undergone a hysterectomy or bilateral oophorectomy or
has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months)
A woman of childbearing potential must have 2 negative serum or urine pregnancy tests at Screening, first within 28 days prior to dosing and the second within 48 hours prior to dosing, and remain on a highly effective method of birth control. The two methods of reliable contraception must include one highly effective method and one additional effective (barrier) method. FCBP must be referred to a qualified provider of contraceptive methods if needed. The following are examples of highly effective and additional effective methods of contraception
Highly effective methods: Intrauterine device (IUD) ; Hormonal (birth control pills, injections, implants) ; Tubal ligation ; Partner's vasectomy
Additional effective methods: Male condom ; Diaphragm CervicalCap
Serum (urine in the case where serum is not possible in a timely manner) pregnancy test to be performed for all women of childbearing potential regularly during the study, In addition, a pregnancy test may be done at any time during the study at the discretion of the investigator if a subject misses a period or has unusual menstrual bleeding
A woman of childbearing potential must remain on a highly effective method of birth control. Contraception must begin 4 weeks before initiating treatment with Ixazomib and Daratumumab, during therapy, during dose interruptions and continuing for 4 months following discontinuation of Ixazomib and Daratumumab. Reliable contraception is indicated even where there has been a history of infertility, unless due to hysterectomy
A man who has not had a vasectomy and who is sexually active with a woman of childbearing potential must agree to use a barrier method of birth control eg, condom with spermicidal foam/gel/film/cream/suppository, and all men must also not donate sperm during the study, for 4 months following discontinuation of Ixazomib and Daratumumab. The exception to this restriction is that if the subject's female partner is surgically sterile, a second method of birth control is not required

Subjects with a history of moderate or severe persistent asthma within the past 2 years (see appendix), or with uncontrolled asthma of any classification at the time of screening (Note that subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed in the study)
