Study of CC-93269, a BCMA x CD3 T Cell Engaging Antibody, in Participants With Relapsed and Refractory Multiple Myeloma

Phase 1
Terminated
Conditions
Multiple Myeloma

Registration Number
NCT03486067
Lead Sponsor
Celgene
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.

Primary Outcome Measures
NameTimeMethod
Adverse Events (AEs)Up to approximately 63 months

Number of participants with Adverse Events

Dose Limiting Toxicity (DLT)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)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)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.

Secondary Outcome Measures
NameTimeMethod
Duration of ResponseUp to 60 months

Is defined as the time from the earliest date of documented response (≥ PR) to the first documented disease progression or death, whichever occurs first.

Time to ResponseUp to 60 months

Is defined as the time from the first CC-93269 dose date to the date of first documented response (PR or better).

Overall Response Rate (ORR)Up to 60 months

Is defined as the proportion of subjects who achieve a partial response or better (eg, PR, VGPR, CR or sCR), according to International Myeloma Working Group (IMWG) response criteria.

Progression Free SurvivalUp to 60 months

Is defined as the time from the first dose of CC-93269 to progressive disease or death from any cause, whichever occurs first.

Overall SurvivalUp to 60 months

Is defined as the time from the first dose of CC-93269 to death from any cause.
