Thereafter, WOCBP participants must use one method of reliable birth control that is highly effective for a further 4 months following discontinuation of

Participants with isolated proteinuria resulting from MM are eligible, provided that they fulfil the other inclusion criteria. 5.Any serious and/or unstable pre-existing medical or, psychiatric disorder or other conditions (including laboratory abnormalities) that could interfere with participant’s safety, obtaining informed consent or compliance with the study procedures. 6.Evidence of active mucosal or internal bleeding uncontrolled by local therapy and not explained by reversible coagulopathy. 7.Current active liver or biliary disease (except for Gilbert’s syndrome or asymptomatic gallstones, or otherwise stable chronic liver disease as per the Investigator’s assessment). 8.Participants with previous or concurrent malignancies other than multiple myeloma. Exceptions are surgically treated cervical carcinoma in situ, or any other malignancy that has been considered medically stable for at least 2 years. The participant must not be receiving active therapy, other than hormonal therapy for this disease. 9.Evidence of cardiovascular risk including any of the following: •Evidence of current clinically significant untreated arrhythmias, including clinically significant ECG abnormalities, second degree (Mobitz Type II) or third degree atrioventricular (AV) block. •History of myocardial infarction, acute coronary syndromes (including unstable angina), coronary angioplasty, or stenting or bypass grafting within 3 months of Screening. 10.Class III or IV heart failure as defined by the New York Heart Association functional classification system. 11.Uncontrolled hypertension. 12.Active infection requiring treatment. 13.Known human immunodeficiency virus HIV infection, unless the participant can meet all of the following criteria: •Established anti-retroviral therapy (ART) for at least 4 weeks and HIV viral load <400 copies/mL. •CD4+ T-cell (CD4+) counts =350 cells/uL. •No history of AIDS-defining opportunistic infections within the last 12 months. 14. Seropositive for hepatitis B (defined by a positive test for hepatitis B surface antigen [HBsAg]). 15.Positive hepatitis C antibody test result or positive hepatitis C RNA test result at screening or within 3 months before the first dose of the study treatment unless the participant can meet the following criteria: •RNA test negative •Successful anti-viral treatment (usually 8 weeks duration) is required, followed by a negative hepatitis c virus (HCV) RNA test after a washout period of at least 4 weeks. 16.Current corneal epithelial disease except for mild punctate keratopathy. 17.Intolerance or contraindications to anti-viral prophylaxis. 18.Unable to tolerate antithrombotic prophylaxis. 19.AL amyloidosis (light chain amyloidosis), active POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma proliferative disorder, skin changes) or active plasma cell leukemia at the time of screening. 20.Exhibiting clinical signs of or with a known history of meningeal or central nervous system involvement by multiple myeloma. 21.Known i
