Who can take part
You may be able to join if
- Relapse multiple myeloma patients that have received 1 or 2 prior lines of therapy including at least to one proteasome inhibitor (bortezomib, carfilzomib or ixazomib), one immunomodulatory drug (lenalidomide is mandatory and patients can be also have been exposed to pomalidomide) and at least one anti-CD38 monoclonal antibody (daratumumab or isatuximab).
- Subject must have pretreatment clinical laboratory values meeting the following criteria during the Screening Phase: hemoglobin ≥8 g/dL; absolute neutrophil count (ANC) ≥ 1.0 x 109/L; platelet count ≥ 25 x109/L; aspartate aminotransferase (AST) ≤2.5 x upper limit of normal (ULN); alanine aminotransferase (ALT) ≤2.5 x ULN; total bilirubin ≤2 x ULN, except in subjects with congenital hyperbilirubinemia, such as Gilbert syndrome (bilirubin ≤3 x ULN); estimated creatinine clearance > 30 mL/min/1.73 m2; corrected serum calcium <14 mg/dL (<3.5 mmol/L); or free ionized calcium <6.5 mg/dL (<1.6 mmol/L).
- Women of childbearing potential must be using a highly effective method of birth control consistent with local regulations regarding the use of birth control methods for subjects participating in clinical studies (see Appendix 13)
- Women of childbearing potential must have a negative serum pregnancy test at screening within 10-14 days and 24 hours before starting treatment. Females of reproductive potential must agree either to abstain continuously from heterosexual sexual intercourse or to use two methods of reliable birth control simultaneously.
- Male Participants: Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. Male participants are eligible to participate if they agree to the following during the intervention period and for at least 100 days: refrain from donating sperm PLUS either: be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR must agree to use contraception/barrier.
- Documented evidence of progressive disease or failure to achieve a response to last line of MM therapy based on investigator's determination of response by IMWG criteria.
You likely can't join if
- Subject has a diagnosis of primary amyloidosis, monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), POEMS syndrome (defined by the presence of peripheral neuropathy, organomegaly, endocrinopathy, monoclonal plasma-cells proliferative disorder, and skin changes) or plasma cell leukemia.
- Impaired cardiovascular function and/or clinically significant cardiovascular diseases, defined as any of the following within 6 months: acute myocardial infarction, acute coronary syndromes (e-g- unstable angina, coronary artery bypass graft, coronary angioplasty or stenting); clinically significant cardiac arrhythmias (e.g. uncontrolled atrial fibrillation or uncontrolled paroxysmal supraventricular tachycardia); thromboembolic or cerebrovascular events (e.g. transient ischemic attack, cerebrovascular accident, deep vein thrombosis, or pulmonary embolism); QTcF interval ≥470 msecs.
- Subject has meningeal involvement of multiple myeloma.
- Pregnant of lactating females.
- Known human immunodeficiency virus (HIV) infection, active infectious hepatitis A, B or C or chronic hepatitis B or C.
- Any serious and/or unstable pre-existing medical, psychiatric disorder or other conditions (including lab abnormalities) not mentioned above that could interfere with participant’s safety, obtaining informed consent or compliance to the study procedures.
