Abstinence from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis), or agree to use a male condom (even if they have undergone a successful vasectomy) 6.2. If applicable, WOCBP (including pregnant females) partners to use an additional highly effective contraceptive method with a failure rate of <1% per year 6.3 Refrain from donating sperm during this period 7. Agree to refrain from donating blood while on trial drug, including during dose interruptions and for 120 days after discontinuation from this trial 8.

Design outcomes

Primary

MeasureTime frame
Dose finding phase: 1. Dose limiting toxicities within the first cycle of treatment measured using measured using adverse event collection and safety assessments between 0 and 28 days Expansion phase: 1. Participant response assessed using the proportion of participants achieving at least a very good partial response (VGPR) whilst on trial treatment using International Myeloma Working Group (IMWG) criteria at the beginning of each cycle up from baseline until disease progression or stopping 2. Safety and toxicity measured using adverse events, graded using the Common Terminology Criteria for Adverse Events (CTCAE version 5.0), Serious Adverse Events (SAEs), Serious Adverse Reactions (SARs), and Serious Unexpected Serious Adverse Reactions (SUSARs), and determined by routine assessments at each site from 0 days until disease progression or stopping

Secondary

MeasureTime frame
1. Overall response rate measured from response assessments, using IMWG criteria, at the beginning of each cycle up from baseline until disease progression or stopping 2. MRD negativity rate measured using IMWG criteria from bone marrow samples taken at 6, 12 and 18 months 3. Progression-free survival measured as the time from registration to first documented evidence of disease progression or death, where response is measured at the beginning of each cycle and diseases progression 4. Maximum response measured from response assessments, using IMWG criteria, at the beginning of each cycle up from baseline until disease progression or stopping 5. Time to maximum response measured from response assessments, using IMWG criteria, at the beginning of each cycle from baseline up until disease progression 6. Duration of response measured from response assessments, using IMWG criteria, at the beginning of each cycle from baseline up until disease progression 7. Compliance to therapy measured using dosing information (such as dose omission, delays, modifications) reported after each cycle of treatment from baseline until disease progression or stopping 8. Quality of life measured using the Myeloma-Specific Quality of Life Questionnaire (MyPOS) at baseline, once every 3 cycles during treatment (starting at C3D1), at end of treatment, and then during post-treatment follow-up at each ophthalmology appointment the participant undergoes for eye toxicity
