Brief Summary:

This is an open-label, multi-center, international, Phase 1 study to assess the safety, PK/PD and preliminary efficacy of CC-92480 in combination with dexamethasone in subjects with RRMM.

All eligible subjects must be refractory to their last line of therapy and have failed, be intolerant to or are not otherwise candidates for available therapies demonstrated to confer clinical benefit to subjects with relapsed and refractory multiple myeloma including (at a minimum), thalidomide, lenalidomide or pomalidomide and a proteasome inhibitor.

  7. Pharmacokinetics- Vz/F [ Time Frame: Up to approximately 28 days ]
    Apparent volume of distribution during terminal phase after non-intravenous administration

  8. Maximum tolerated dose (MTD) [ Time Frame: Up to approximately 28 days ]
    The highest dose of CC-92480 in combination with dexamethasone associated acceptable safety and tolerability.

Secondary Outcome Measures :
  1. Overall response rate (ORR) [ Time Frame: Up to approximately 3 years ]
    Best response ≥ partial response (PR), according to the IMWG Uniform Response Criteria

  2. Time to response (TTR) [ Time Frame: Up to approximately 3 years ]
    Time from 1st dose of CC-92480 to the first documentation of response ≥ PR.

  3. Duration of response (DOR) [ Time Frame: Up to approximately 3 years ]
    Time from the first documentation of response (≥ PR) to the first documentation of PD or death.

  4. Progression free survival [ Time Frame: Up to approximately 3 years ]
    Time from 1st dose of CC-92480 to the first occurrence of disease progression or death from any cause.
