Brief summary

This study is being done to evaluate the safety, tolerability and effectiveness of Oral CG-806 for the treatment of patients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), or Non-Hodgkin's Lymphomas who have failed or are intolerant to two or more lines of established therapy or for whom no other treatment options are available.

Detailed description

This is a multicenter, open-label, Phase Ia/b dose escalation study of safety, pharmacodynamics, and pharmacokinetics of CG-806 in ascending cohorts (3+3 design) to determine the MTD or recommended dose in patients with relapsed or refractory CLL/SLL or Non-Hodgkin's Lymphoma patients. This is to be followed by a cohort expansion phase at the MTD or recommended oral dose.

Interventions

DRUGCG-806

CG-806 will be given orally in ascending doses starting at 150 mg PO BID until the maximum tolerated dose or recommended dose is reached.
