Safety Study of CC-292 and Rituximab in Subjects With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
This is a dose finding study using a 3 + 3 dose escalation and expansion design to determine a Not Tolerated Dose (NTD), Optimal Biological Effect Dose (OBE) and / or Maximum Tolerated Dose (MTD). These data will be used to establish a Recommended Phase 2 Dose (RP2D) for the combination of CC-292 and Rituximab in subjects with CLL.

Experimental: CC-292 with Rituximab
Cohort 1: 375 mg CC-292 will be administered twice a day on Days 1-28 Cohort 2: 500 mg CC-292 will be administered twice a day on Days 1-28Drug: Rituximab
Cohort 1: Rituximab once per cycle Cohort 2: Rituximab once per cycle
This dose finding study uses a 3 + 3 dose escalation and expansion design to establish the recommended Phase 2 dose (RP2D). Treatment will consist 28 day treatment cycles with a single Rituximab infusion per cycle for 6 cycles and twice daily (days 1-28) administration of CC-292 with a starting dose cohort of 375mg twice a day. Following safety review of the data from the initial cohort and confirmation that the initial dose is tolerable, the next dose level will be enrolled with a once per cycle Rituximab infusion for 6 cycles and twice daily CC-292 at 500 mg.
Determination of the maximum tolerated dose and/or optimal biologic effect will be used to establish a dose for evaluation in an expansion cohort of 24 subjects. Evaluation of the data for subjects in the expansion cohorts will result in establishment of a RP2D.
