Study of Zanubrutinib in Older Patients With Previously Untreated Chronic Lymphocytic Leukemia (CLL) (ZEN-CLL)

2026年9月9日 更新者：The Lymphoma Academic Research Organisation

ZEN-CLL - A Phase II Trial Evaluating Zanubrutinib in Elderly, Treatment-Naïve, CLL Patients

This phase II, open-label, multicenter study evaluates zanubrutinib in patients aged 80 years and older with previously untreated chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who require treatment.

CLL and SLL are slow-growing blood cancers that mainly affect older adults. Although zanubrutinib is an effective treatment, taking it continuously at the full dose may increase the risk of side effects over time, particularly in elderly patients. The study aims to assess whether a planned reduction in the dose of zanubrutinib after an initial period of treatment can maintain disease control while improving long-term tolerability.

詳細な説明

The ZEN-CLL study is evaluating a treatment strategy based on zanubrutinib in previously untreated elderly patients with CLL or small lymphocytic lymphoma (SLL). Approximately 95 participants will be enrolled in 17 LYSA centers in France.

All participants will receive zanubrutinib 160 mg twice daily for the first 18 months of treatment. After Month 18, the dose will be reduced according to the dose received at that time and the participant's tolerability. Treatment will continue until permanent treatment discontinuation or the end of study participation.

The study aims to determine whether this dose reduction strategy can maintain disease control while improving long-term tolerability in this elderly population.
