What this trial studies
This study evaluates the efficacy and safety of APG-2575, an oral medication, in patients suffering from relapsed or refractory Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL). It is a single-arm, open-label, multi-center Phase II trial that aims to enroll approximately 75 participants who have previously failed or are intolerant to other treatments. Participants will take APG-2575 at a dose of 600mg once daily for 28-day cycles until the end of treatment criteria are met.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with limited treatment alternatives for CLL/SLL.
How similar studies have gone: Other studies have shown promising results with similar approaches in treating CLL/SLL, indicating potential for success.
