Overview
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.

Outcomes
Primary Outcomes
Adverse Events (AEs)
Time Frame: Up to approximately 63 months
Number of participants with Adverse Events
Dose Limiting Toxicity (DLT)
Time Frame: Up to 60 months
Is 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)
Time Frame: Up to 60 months
Is 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)
Time Frame: Up to 60 months
Is 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.
