a study to evaluate icp-022 in patients with cll/ sll

Conditions: CLL/SLL

Summary: the phase i/ii clinical study is to investigate the safety, tolerability and efficacy of icp-022 in r/r cll/sll patients.

part i: safety evaluation -2 regimens of icp-022 (high and low dose qd) are designed for safety assessment. the recommended dose of phase ii clinical study will be determined according to the part i results. part ii: dose expansion -anti-tumor effects of icp-022 in chinese patients with r/r cll/sll will be evaluated in approximately 80 subjects. the recommended phase 2 dose will be used in the part ii.
