Primary purpose: TREATMENT

Brief summary: This is a phase I, first in human, single arm, open label study that will assess safety, tolerability and clinical activity of FHND6091 when taken orally on a weekly dosing schedule by patients with relapsed and refractory multiple myeloma (RRMM).The study will consist of two parts: dose escalation (Part 1) and dose expansion (Part 2).The dose escalation (Part 1) of the study will evaluate the safety and tolerability of FHND6091 using a dose escalation scheme to establish a maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D). And the dose expansion (Part B) of the study will further evaluate the safety, pharmacokinetics (PK)/ pharmacodynamics (PD), and efficacy of FHND6091 at two selected dose levels to characterize the safety, tolerability and efficacy of FHND6091.

A total of 40 evaluable participants will be enrolled in the study. The participants receiving treatment in part 1 and part 2 may continue combination treatment for a total of up to 12 cycles. After 12 cycles of therapy, the participants will continue treatment until the occurrence of PD, intolerable AEs, consent withdrawal, death or end of study based on the judgement of investigator's assessment.
