Combining Venetoclax, Rituximab, and Ibrutinib for Treating Chronic Lymphocytic Leukemia

Official title: Venetoclax and Delayed Rituximab With Ibrutinib Consolidation Aiming at Undetectable Minimal Residual Disease (uMRD) in Treatment-naïve Patients With Chronic Lymphocytic Leukemia (CLL)

Run by IRCCS San Raffaele · NCT04758975 · Data updated 2026-11-12

This study is testing if adding ibrutinib to a year-long treatment of venetoclax and rituximab can help people with newly diagnosed Chronic Lymphocytic Leukemia reach a state where the disease is undetectable.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are treatment-naïve adults aged 18 to 64 years with active CLL requiring treatment.

Probably not a fit

Patients with a history of prior CLL treatment or those with certain comorbidities 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 Phase 2, multicenter, open-label interventional study evaluates the effectiveness of adding ibrutinib to a 12-month treatment regimen of venetoclax and rituximab in patients with treatment-naïve Chronic Lymphocytic Leukemia (CLL) who have undetectable minimal residual disease (uMRD). The treatment involves an initial ramp-up of venetoclax followed by a combination with rituximab, with the goal of achieving uMRD status by the end of the treatment cycles. Patients will be monitored for their MRD status to determine the continuation or cessation of therapy based on their response. This approach aims to optimize treatment outcomes for CLL patients.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for patients with CLL by achieving and maintaining undetectable minimal residual disease.

How similar studies have gone: Other studies have shown promising results with similar combinations of targeted therapies in CLL, suggesting potential for success in this approach.
