An Open-Label, Multicenter, Phase I Study to Evaluate the Safety, Pharmacokinetics and Preliminary Efficacy of YY201 in Patients With Advanced Solid Tumors and Hematological Malignancies
This is a multicenter, open-label, phase I clinical study of YY201 in the patients with relapsed/refractory lymphomas and relapsed/refractory large granular lymphocytic leukemia who failed or cannot tolerate standard treatment.
This study includes a dose escalation phase and a dose expansion phase. In the dose escalation phase the MTD and/or RP2D of YY201 will be determined and in the dose expansion phase the anti-tumor efficacy of YY201 will be evaluated in patients with relapsed⁄refractory hematological malignancies. The two-phase study will assess the preliminary anti-tumor efficacy , safety, tolerability, and PK profile of YY201 .
Inclusion Criteria:
1.Patients fully understand and sign ICF, voluntarily participate in the study, and able to follow and complete all study procedures.
