Brief summary

Study CC-99712-MM-001 is an open-label, Phase 1, dose escalation (Part A) and expansion (Part B), First-in-Human (FIH) clinical study of CC-99712 in monotherapy or combination with BMS-986405 in participants with relapsed and refractory multiple myeloma (MM). The dose escalation part (Part A) of the study will evaluate the safety and tolerability of escalating doses of CC-99712, administered intravenously (IV) in monotherapy (Arm 1) or combination with BMS-986405 (Arm 2), to determine the maximum tolerated dose (MTD) of CC-99712 guided by a Bayesian logistic regression model (BLRM). A modified accelerated titration design will also be used for Arm 1 and Arm 2. The MTD may be established separately for CC-99712 administered at Q3W and/ or Q4W schedules. The expansion part (Part B) will further evaluate the safety and efficacy of CC-99712 in monotherapy (Arm 1) or combination (Arm 2) administered at or below the MTD in selected expansion cohorts in order to determine the RP2D. One or more doses or dosing regimens may be selected for cohort expansion. All participants will be treated until confirmed disease progression per IMWG criteria, unacceptable toxicity, or participants//Investigator decision to withdraw.

Design outcomes

Primary

MeasureTime frameDescription
Adverse Events (AEs)From enrollment until at least 42 days after completion of study treatmentNumber of participants with adverse event
Maximum Tolerated Dose (MTD) in participants with relapsed and refractory MMUp to 28 daysIs defined as the highest dose that causes DLTs in no more than 33% of patient population during the first cycle of treatment.
Dose Limiting Toxicity (DLT) in participants with relapsed and refractory MMUp to 28 daysIs defined as any of the following toxicities occurring within the DLT assessment window

Secondary

MeasureTime frameDescription
Duration of ResponseUp to 3 yearsIs defined as the time from the earliest date of documented response (≥ PR) to the first documented disease progression or death, whichever occurs first.
Progression-free Survival (PFS)Up to 3 yearsIs defined as the time from the first dose of CC-99712 to progressive disease (PD) or death from any cause, whichever occurs first.
Pharmacokinetics- CtroughUp to 3 yearsLowest concentration of drug immediately prior to administration of the next dose
Overall Survival (OS)Up to 3 yearsIs defined as the time from the first dose of CC-99712 to death from any cause.
Pharmacokinetics- CLTUp to 3 yearsTotal body clearance of the drug from the serum
Pharmacokinetics- TmaxUp to 3 yearsTime to peak (maximum) serum concentration
Pharmacokinetics- AUC(TAU)Up to 3 yearsArea under the serum concentration time-curve
Presence and frequency of ADA using a validated bridging immunoassay with electrochemiluminescence detectionUp to 3 yearsAnti-CC-99712 antibodies
Pharmacokinetics- CmaxUp to 3 yearsMaximum plasma concentration of drug
Overall Response Rate (ORR)Up to 3 yearsIs defined as the proportion of participants who achieve a partial response or better (eg, Partial response (PR), Very good partial response (VGPR), Complete response (CR) or sCR), according to IMWG response criteria.
Time to ResponseUp to 3 yearsIs defined as the time from the first CC-99712 dose date to the date of first documented response (PR or better).
