What this trial studies

This study aims to evaluate the safety of novel dosing and ramp-up schedules for the experimental drug sonrotoclax in patients with chronic lymphocytic leukemia (CLL). The approach involves gradually increasing the dose of sonrotoclax over specified periods to reach the target daily dose while monitoring for tumor lysis syndrome and related toxicities. Initially, small groups of participants will test each dosing schedule for safety, followed by a larger group to further assess the approved schedules. The goal is to optimize the dosing regimen to enhance patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults with a confirmed diagnosis of CLL who require treatment and have stable organ function.

Not a fit: Patients with active viral infections or those unable to comply with the study protocol may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer and more effective treatment options for patients with chronic lymphocytic leukemia.

How similar studies have performed: Other studies have explored dosing schedules for similar treatments, but this specific approach with sonrotoclax is novel.
