Dose limiting toxicities within the first cycle of treatment measured using measured using adverse event collection and safety assessments between 0 and 28 days<br><br>Expansion phase:<br>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 <br>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
