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.

RRMM patient previously treated with at least 3 prior regimens including lenalidomide or pomalidomide, a proteasome inhibitor and a CD38 antibody will be eligible.

Estimated Enrollment : 80 participants
Intervention Model: Sequential Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1 Multicenter, Open-label Study to Assess the Safety, Pharmacokinetics and Preliminary Efficacy of CC-92480 in Combination With Dexamethasone in Subjects With Relapsed and Refractory Multiple Myeloma
Actual Study Start Date : February 6, 2018
Estimated Primary Completion Date : December 26, 2021
Estimated Study Completion Date : May 6, 2022

Arm Intervention/treatment
Experimental: Administration of CC-92480 and Dexamethasone
Escalating doses of CC-92480 in combination with a fixed dose of dexamethasone administered according to two different dosing schedules
Drug: CC-92480

Drug: Dexamethasone

Primary Outcome Measures :
  1. Adverse Events (AEs) [ Time Frame: From enrollment until at least 28 days after completion of study treatment ]
    Number of participants with AEs (Type, frequency, seriousness, severity and relationship of AEs to CC-92480 and dexamethasone; changes from baseline in clinically-relevant physical findings, vital signs, selected laboratory analytes, ECGs).

  2. Pharmacokinetics- AUC [ Time Frame: Up to approximately 28 days ]
    Area under the plasma concentration-time curve

  3. Pharmacokinetics- Cmax [ Time Frame: Up to approximately 28 days ]
    Maximal plasma concentration

  4. Pharmacokinetics- Tmax [ Time Frame: Up to approximately 28 days ]
    Time to Cmax

  5. Pharmacokinetics- t1/2 [ Time Frame: Up to approximately 28 days ]
    Terminal-phase elimination half-life

  6. Pharmacokinetics- CL/F [ Time Frame: Up to approximately 28 days ]
    Apparent total clearance of the drug from plasma after oral administration

  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.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Subject is ≥ 18 years of age and ECOG performance status score of 0, 1 or 2
  2. All subjects must have:

    1. received at least 3 prior anti-myeloma regimens including at least 2 consecutive cycles of lenalidomide, pomalidomide, a proteasome inhibitor, a glucocorticoid and a CD38 antibody (note: induction with or without bone marrow transplant and with or without maintenance therapy is considered one regimen),
    2. documented disease progression on or within 60 days from the last dose of their last myeloma therapy,
    3. in addition to criteria above (a and b), subjects enrolled in Part 2 must have disease refractory to an immunomodulatory agent (lenalidomide and/or pomalidomide), a glucocorticoid, a proteasome inhibitor, and a CD38 antibody. Refractory is defined as disease that is nonresponsive on therapy (failure to achieve minimal response or development of progressive disease), or progresses within 60 days of last dose.
  3. Subjects must have adequate bone marrow, renal, liver, and cardiac function.
  4. Females of childbearing potential (FCBP) and male subjects must agree with the pregnancy prevention plan.

Exclusion Criteria:

  1. Subject has a significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study.
  2. Subject has non- or oligosecretory multiple myeloma.
  3. Subject is unable or unwilling to undergo protocol required venous thromboembolism (VTE) prophylaxis.
