A Phase 1, First-in-Human, Multicenter, Open-Label, Dose Escalation and Dose-Expansion Study of Single-Agent ISB 2001 in Subjects With Relapsed/Refractory Multiple Myeloma

Description

This study is a first-in-human, Phase 1, open-label study that will evaluate safety and anti-myeloma activity of ISB 2001 in participants with relapsed/refractory multiple myeloma (R/R MM).The study will enroll participants with R/R 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 parts: * Part 1: Dose escalation * Part 2: 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. Dose expansion cohorts will be initiated to further confirm safety and optimal biologically active dose. Participants will receive ISB 2001 until disease progression, unacceptable toxicity occurs, any criterion for stopping the study treat

Trial Eligibility

Inclusion Criteria: 1. Participants with pathologically confirmed MM with measurable M-protein: serum and/or 24 hour urine, serum-free light chains or measurable isolated plasmacytoma 2.
