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 Disease:Multiple Myeloma
  • Intervention/Treatment: Drug: CC-93269
  • Phase: 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) [ Time Frame: Up to 60 months ]
    Number of participants with Adverse Events
  • 2. 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.
  • 3. 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.
  • 4. 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.
  • Secondary Outcome Measures: 1. Overall Response Rate (ORR) [ Time Frame: 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.
  • 2. Time to Response [ Time Frame: Up 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).
  • 3. Duration of Response [ Time Frame: Up 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.
  • 4. Progression Free Survival [ Time Frame: Up 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.
  • 5. Overall Survival [ Time Frame: Up to 60 months ]
    Is defined as the time from the first dose of CC-93269 to death from any cause.
  • 6. Pharmacokinetics - Cmax [ Time Frame: Up to 60 months ]
    Maximum serum concentration of drug
  • 7. Pharmacokinetics - Cmin [ Time Frame: Up to 60 months ]
    Minimum serum concentration of drug
  • 8. Pharmacokinetics - AUC [ Time Frame: Up to 60 months ]
    Area under the curve
  • 9. Pharmacokinetics - tmax [ Time Frame: Up to 60 months ]
    Time to peak (maximum) serum concentration
  • 10. Pharmacokinetics - t1/2 [ Time Frame: Up to 60 months ]
    Terminal Half-life
  • 11. Pharmacokinetics - CL [ Time Frame: Up to 60 months ]
    Apparent total body clearance
  • 12. Pharmacokinetics - Vss [ Time Frame: Up to 60 months ]
    Volume of distribution at steady-state
  • 13. Pharmacokinetics - accumulation index of alnuctamab [ Time Frame: Up to 60 months ]
    Accumulation ratio of drug
  • 14. Presence and frequency of anti-drug antibodies (ADA) [ Time Frame: Up to 60 months ]
    Detection of anti-drug antibodies in participants and frequency of anti-drug antibodies
  • 15. Evaluate measures of tumor sensitivity/ resistance to CC-93269 [ Time Frame: Up to 60 months ]
    Measurement of tumor and immune factors
