Ibrutinib in Previously Untreated Binet Stage A Chronic Lymphocytic Leukemia With Risk of Disease Progression

Summary

This is a prospective, multicenter, randomized, placebo-controlled, double-blind phase III study that compares the efficacy and safety of oral ibrutinib in previously untreated Binet stage A CLL patients without treatment indication according to iwCLL guidelines but risk of early disease progression. For event-free survival (EFS), an improvement from 24 months for untreated intermediate or (very) high risk CLL to 48 months for subjects treated with ibrutinib is considered clinically relevant. Ibrutinib / placebo is administered continuously orally until symptomatic disease progression, unacceptable toxicity, or voluntary treatment withdrawal, whichever occurs first.
