Details and patient eligibility

About

This is an open-label, prospective and exploratory clinical study to evaluate the efficacy and safety of JAK inhibitor SHR-0302 in combination with EZH2 inhibitor SHR-2554 in patients with R/R PTCL. The study plans to enroll approximately 25 patients. 6-12 patients will receive SHR-0302 monotherapy and SHR-0302+SHR-2554 combination therapy in the safety run-in phase. According to the safety observed, the investigators discuss and decide to select a dose group to explore the efficacy and safety. 13 patients may be enrolled in the expansion phase.

Full description

This is an open-label, prospective, exploratory clinical study. The plan is to enroll 12-25 patients with relapsed/refractory peripheral T-cell lymphoma (r/r PTCL) to receive a combination of SHR-0302 and SHR-2554. The primary objectives are to evaluate the efficacy and safety of the SHR-0302 and SHR-2554 combination in the treatment of r/r PTCL. Subjects will receive the investigating drugs combination (SHR-0302 and SHR-2554) until study completion, unacceptable toxicity, disease progression, withdrawal of informed consent, or investigators discontinue treatment.

The study is divided into two parts. Part I is a safety run-in phase, and part II is an efficacy exploration phase.

Part I:

Cohort 1: Explore the recommended dose and safety of SHR-0302 monotherapy Cohort 2: Based on the efficacy and safety observed in Cohort 1, explore the clinically recommended dose and safety of the SHR-0302 and SHR-2554.

Part II: Based on the safety and tolerability observed during part I, the investigators will discuss and select one tolerable dose cohort to explore the efficacy and safety.
