Study Details

Study Description

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.

Condition or DiseaseIntervention/TreatmentPhase
Phase 1

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 2 years or extended up to 5 years for subjects maintaining clinical benefit at the discretion of the Safety Review Committee, until confirmed disease progression, unacceptable toxicity, or subject/investigator decision to withdraw.

Outcome Measures

Primary Outcome Measures

  1. Adverse Events (AEs) [Up to 48 months]

    Number of participants with Adverse Events

  2. Dose Limiting Toxicity (DLT) [Up to 48 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.

  3. Non-Tolerated Dose (NTD) [Up to 48 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.

  4. Maximum Tolerated Dose (MTD) [Up to 48 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

  1. Overall Response Rate (ORR) [Up to 48 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.

  2. Time to Response [Up to 48 months]

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

  3. Duration of Response [Up to 48 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.

  4. Progression Free Survival [Up to 48 months]

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

  5. Overall Survival [Up to 48 months]

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

  6. Pharmacokinetics - Cmax [Up to 48 months]

    Maximum serum concentration of drug

  7. Pharmacokinetics - Cmin [Up to 48 months]

    Minimum serum concentration of drug

  8. Pharmacokinetics - AUC [Up to 48 months]

    Area under the curve

  9. Pharmacokinetics - tmax [Up to 48 months]

    Time to peak (maximum) serum concentration

  10. Pharmacokinetics - t1/2 [Up to 48 months]

    Terminal Half-life

  11. Pharmacokinetics - CL [Up to 48 months]

    Apparent total body clearance

  12. Pharmacokinetics - Vss [Up to 48 months]

    Volume of distribution at steady-state

  13. Pharmacokinetics - accumulation index of CC-93269 [Up to 48 months]

    Accumulation ratio of drug

  14. Presence and frequency of anti-drug antibodies (ADA) [Up to 48 months]

    Detection of anti-drug antibodies in participants and frequency of anti-drug antibodies

  15. Evaluate measures of tumor sensitivity/ resistance to CC-93269 [Up to 48 months]

    Measurement of tumor and immune factors
