Patients who undergo intraperitoneal dialysis may also be included. 8.Eastern Cooperative Oncology Group (ECOG) performance status score of ≤ 2. 9.Willingness and ability to participate in study procedures. 10.Reproductive Status a)Women of childbearing potential (WOCBP) must have two negative serum or urine pregnancy tests, one 10-14 days prior to start of the study drug and one within 24 hours prior to the start of study drug. 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 treatment with study drugs, for the duration of treatment with study drugs, and for 3 months after cessation of study treatment. 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 treatment with study drugs, for the duration of treatment with study drugs, and for a total of 90 days post-treatment completion. on. The additional contraception of female partners of childbearing potential should also be considered. e)Male patients must not donate sperm for up to 90 days post treatment completion. f)Female patients must not donate eggs for up to 90 days post treatment completion. g)Azoospermic males and WOCBP who are not heterosexually active are exempt from contraceptive requirements. However, WOCBP will still undergo pregnancy testing as described in this section.
Highly effective methods of contraception have a failure rate of < 1% when used consistently and correctly. Subjects must agree to the use of two methods of contraception, with one method being highly effective (tubal ligation, intrauterine device [IUD], hormonal [birth control pills, injections, hormonal patches, vaginal rings or implants] or partner’s vasectomy) and the other method being additionally effective (male latex or synthetic condom, diaphragm, or cervical cap).

E.4 | Principal exclusion criteria |
1.Previous therapy with daratumumab or other anti-CD38 therapy. 2.Anti-myeloma treatment within 2 weeks prior to Cycle 1, Day 1. 3.Cumulative dose of corticosteroids greater than or equal to the equivalent of 140mg prednisone for ≥ 4 days or a dose of corticosteroids greater than or equal to the equivalent of 40 mg/day of dexamethasone for ≥ 4 days within the 2-week period prior to Cycle 1, Day 1. 4.Previous allogenic stem cell transplant; or Autologous Stem Cell Transplantation (ASCT) within 12 weeks before Cycle 1, Day 1. 5.Clinical signs of meningeal involvement of multiple myeloma. 6.Subject has either of the following: a.Chronic obstructive pulmonary disease (COPD) with a Forced Expiratory Volume in 1 second (FEV1) <50% of predicted normal. Note that FEV1 testing is required for subjects suspected of having COPD and subjects must be excluded if FEV1 <50% of predicted normal. b.Known moderate or severe persistent asthma (see Appendix 7), within 2 years from C1D1, or currently has uncontrolled asthma of any classification. Note that subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed to participate in the study. 7.Clinically significant cardiac disease, including: a)Myocardial infarction within 1 year, or unstable or uncontrolled condition (e.g., unstable angina, congestive heart failure, New York Heart Association Class III-IV). b)Uncontrolled cardiac arrhythmia (CTCAE Grade 2 or higher) (atrial fibrillation with controlled ventricular rate is allowed) or clinically significant ECG abnormalities. c)ECG showing a baseline QT interval as corrected by Fridericia’s formula (QTcF) >470 msec. 8.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.
