A Phase 1/2, Open-label, Dose Finding Study to Evaluate CC-122 in Combination With Ibrutinib and Obinutuzumab in Subjects With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
Safety, pharmacokinetics, and preliminary efficacy of CC-122 alone and in combination with ibrutinib and obinuzutumab. CC-122 has multiple activities, including immune modulation of several immune cell subsets and antiproliferative activity in CLL. CC-122 has also been shown to have a tolerable safety profile with some preliminary signs of efficacy with early human experience.
Phase 1/2 Study to Determine the Safety, Pharmacokinetics, and Efficacy of Single Agent CC-122 and the Combinations CC-122 AND Ibrutinib and CC-122 and Obinutuzumab in Subjects With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
The primary objectives of this Phase 1/2 Study are to determine the safety of single agent CC-122 and the safety, tolerability, and RP2D of CC-122 when administered in combination with ibrutinib and in combination with obinutuzumab to subjects with CLL/SLL. The secondary objectives are to evaluate the PK profiles of subjects administered CC-122 in combination with ibrutinib and in combination with obinutuzumab, to determine ibrutinib concentrations when given alone and in combination with CC-122 and to evaluate the preliminary efficacy of CC-122 at selected dose levels/regimens.
