Study Title

A Phase 1, Multi-center, Open-label, Study to Assess the Safety, Pharmacokinetics, Pharmacodynamics, and Preliminary Efficacy of an Orally Available Small Molecule CC-99282 Alone and in Combination with Rituximab in Subjects with Relapsed and/or Refractory Diffuse Large B Cell Lymphoma (R/R DLBCL) and Indolent Non-Hodgkin Lymphoma (R/R iNHL)


The purpose of this study is to test the safety of the new experimental drug, CC-99282. For some participants with DLBCL or FL enrolling in Part B of the study, an additional purpose is to test the safety of CC-99282 in combination with rituximab.


Primary Objectives: To determine the safety and tolerability of CC-99282 alone and in combination with rituximab in subjects with R/R NHL. To define the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of CC-99282 in subjects with R/R NHL. Secondary Objectives: To characterize the pharmacokinetics (PK) of CC-99282. To provide information on the preliminary efficacy of CC-99282 alone and in combination with rituximab in R/R NHL.

  • Agree to follow the CC-99282 Pregnancy Prevention Plan (PPP)

  • Exclusion Criteria

  • Participant has life expectancy ≤ 2 months.
  • Participant has received prior systemic anti-cancer treatment (approved or investigational) ≤ 5 half-lives or 4 weeks prior to starting CC-99282, whichever is shorter.
  • Participant has symptomatic CNS involvement of disease (does not apply to PCNSL participants in Part B).
  • Participant is on chronic systemic immunosuppressive therapy or corticosteroids (eg, prednisone or equivalent not to exceed 10 mg per day within the last 14 days) or participants with clinically significant graft-versus-host disease (GVHD).
  • Participant had prior autologous SCT ≤ 3 months prior to starting CC 99282 and any treatment-related toxicity is unresolved (grade > 1).
  • Participant had prior allogeneic SCT with either standard or reduced intensity conditioning ≤ 6 months prior to starting CC-99282. If participant had prior allogeneic SCT > 6 months prior to the start of CC-99282, any treatment-related toxicity is unresolved (grade > 1).
