A Study to Determine Dose, Safety, Tolerability, Drug Levels, and Efficacy of CC-220 Monotherapy, and in Combination With Other Treatments in Participants With Multiple Myeloma
18 Years and older, Male and Female
This is a multicenter, multi-country, open-label, Phase 1b/2a dose-escalation study
consisting of two parts: dose escalation (Part 1) for CC-220 monotherapy, CC-220 in
combination with DEX, CC-220 in combination with DEX and DARA, CC-220 in combination with DEX
and BTZ and CC-220 in combination with DEX and CFZ; and the expansion of the RP2D (Part 2)
for CC-220 in combination with DEX for Relapsed Refractory Multiple Myeloma and CC-220 in
combination with DEX and BTZ for Newly Diagnosed Multiple Myeloma.
Subjects assigned to CC-220 monotherapy, who develop progressive disease (PD) will have the
option to receive DEX in addition to CC-220 after consultation with the Medical Monitor. The
dose of CC-220 will not be higher than the dose of CC-220 used in combination with
dexamethasone in Cohort B that has been determined to be safe. Progressive disease must be
confirmed in accordance with international myeloma working group (IMWG) criteria.
The starting dose of DEX will be 40 mg for subjects who are =75 years of age and 20 mg for
subjects who are >75 years of age, given once weekly. This treatment will continue until PD,
unacceptable toxicity or the subject withdraws consent.
For Cohorts A and B, the starting dose level of CC-220, dose level 1, is 0.3 mg. A dose level
-1, of 0.15 mg, may also be evaluated if the starting dose level of 0.3 mg for 21 days of a
28-day cycle is not tolerated. For Cohorts E and F, the starting dose level of CC-220, dose
level 1, is one dose level below the maximum dose for Cohort B that has been determined to be
safe by the dose escalation committee (DEC) at the start of enrollment for both cohorts. For
Cohort E in addition to CC-220 and DEX, daratumumab will be administered intravenously (IV)
at a 16mg/kg dose. For Cohort F in addition to CC-220 and DEX, bortezomib will be
administered subcutaneous (SC) at a 1.3mg/m2 dose.
All subjects with a minimal response (MR) or better who discontinue study treatment in Part 1
or Part 2 of the study for a reason other than PD or withdrawal of consent from the study
will be followed for response assessment every 28 days (every 21 days for Cohort F) until PD.
The study will be conducted in compliance with the International Council for Harmonisation
(ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use/Good
Clinical Practice (GCP) and applicable regulatory requirements.
The initiation of Part 2 will begin when the RP2D is established in Part 1 in either Cohort A
or Cohort B. Either cohort may begin once the RP2D is determined for each cohort
independently during Part 1. All expansion decisions will be determined by the DEC after
review of all safety, PK, biomarker and preliminary efficacy data, as applicable. During Part
2, the Independent Expert Reviewer will review safety data and any other data deemed relevant
so that subject safety is ensured.
- Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1 or 2
- Relapsed and refractory multiple myeloma (RRMM) participants must have documented disease progression on or within 60 days from the last dose of their last myeloma therapy
- Newly diagnosed multiple myeloma (NDMM) participants must have documented diagnosis with previously untreated symptomatic multiple myeloma (MM)
- Participants in Cohorts J1 and K are those for whom autologous stem cell transplantation is not planned for initial therapy or are not considered by the investigator as eligible for high-dose chemotherapy and autologous stem cell transplantation
