Study of APG-2575 in Patients With Relapsed/Refractory CLL/SLL

Официальное название

A Single-arm, Pivotal Registration Phase II Study of the Efficacy and Safety of APG-2575 Monotherapy in Relapsed or Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

Обзор

The purpose of this study is to assess the efficacy and safety of APG-2575 single agent in patients with relapsed/refractory CLL/SLL.

Подробное описание

This is an single-arm, open-label, multi-center, pivotal registration Phase II study of efficacy and safety of APG-2575 as a single agent in relapsed/refractory CLL/SLL patients.

This study plans to enroll approximately 75 CLL/SLL subjects who have failed or are intolerant to prior immunochemotherapy and BTK inhibitor therapy. Eligible subjects will receive APG-2575 600mg, orally administered once daily (QD), within half an hour of a low-fat meal, for a cycle of 28 days. Participants will continue to accept APG - 2575 until the "end of treatment" that are consistent with the provisions in the solution of the termination of any specified standards.
