Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with documented CLL who have previously responded to venetoclax combined with an anti-CD20 antibody and have experienced disease progression after a specified time frame.

Probably not a fit

Patients who have received intervening treatment for CLL after their initial venetoclax therapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of a combination treatment using oral venetoclax and intravenous obinutuzumab in adults with recurring chronic lymphocytic leukemia (CLL) who have previously undergone treatment. Participants will be divided into two cohorts based on the timing of their disease progression after first-line therapy. The treatment will consist of 28-day cycles of venetoclax and obinutuzumab, followed by additional cycles of venetoclax alone. The study aims to monitor changes in disease activity and any adverse events associated with the treatment.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with recurring CLL.

How similar studies have gone: Other studies have shown promising results with similar treatment approaches for CLL, indicating potential for success in this trial.
