Summary
This study will enrol people with relapsed/refractory (R/R) multiple myeloma (MM) that have been treated with immunomodulatory drugs (IMiDs), proteasome inhibitors, and anti-CD38 therapies either in combination or as a single agent, and are refractory to, or intolerant of, established therapies known to provide clinical benefit in MM.
The study will be conducted in two phases: Dose Escalation and Dose Expansion.
Dose Escalation will continue until either the maximum tolerated dose (MTD) is defined, the maximum planned dose is reached, or a recommended phase 2 dose (RP2D) is selected. In thise phase, people with R/R MM will be administered ISB 2001 weekly on Days 1, 8, 15, and 22 of each 28-day cycle, with an additional set-up dose in Cycle 1 on Day 4.
Dose Expansion cohorts will be initiated to further confirm safety and optimal biologically active dose at each putative recommended Phase 2 dose(s).
