Brief summary

Study CC-93269-MM-001 is an open-label, Phase 1, dose escalation (Part A and C) and expansion (Parts B and D), first-in-human clinical study of CC-93269 in subjects with relapsed and refractory multiple myeloma.

Detailed description

The dose escalation parts (Part A with CC-93269 administered intravenous (IV) and Part C subcutaneous (SC)) of the study will evaluate the safety and tolerability of escalating doses of CC-93269, administered IV or SC, to determine the maximum tolerated dose (MTD) and non-tolerated dose (NTD) of CC-93269. The expansion parts (Part B and D) will further evaluate the safety and efficacy of CC-93269 administered IV or SC at or below the MTD in selected expansion cohorts of up to approximately 20 evaluable subjects each in order to determine the Recommended Phase 2 dose (RP2D).One or more dosing regimens may be selected for cohort expansion. All treatments will be administered in 28-day cycles for up to 5 years for subjects maintaining clinical benefit, or until confirmed disease progression, unacceptable toxicity, or subject/investigator decision to withdraw.

Design outcomes

Primary

MeasureTime frameDescription
Adverse Events (AEs)Up to approximately 63 monthsNumber of participants with Adverse Events
Dose Limiting Toxicity (DLT)Up to 60 monthsIs defined as any of the toxicities occurring within the DLT assessment window (Cycle 1, Days 1 to 28) except those that are clearly and incontrovertibly due to extraneous causes.
Non-Tolerated Dose (NTD)Up to 60 monthsIs defined as a dose level at which 2 or more of up to 6 evaluable subjects in any dose cohort experience a DLT in the DLT window.
Maximum Tolerated Dose (MTD)Up to 60 monthsIs defined as the last dose cohort below the NTD with 0 or 1 out of 6 evaluable subjects experiencing a DLT during the DLT window.
