Key clinical point: Ibrutinib showed efficacy in a real-world cohort of patients with previously untreated high-risk chronic lymphocytic leukemia (CLL) carrying 17p- or TP53 mutations (TP53 aberrations).
Major finding: At 24 months, the median overall survival was not reached; the estimated treatment persistence and survival rates were 63.4% (95% CI 60.0%-67.0%) and 82.6% (95% CI 79.9%-85.4%), respectively. The median time to treatment discontinuation was 37.4 months (95% CI 34.8-42.2 months). Disease progression or death were the reasons for discontinuation in 45.8% of patients.
Study details: This real-world registry study analyzed the data of 747 patients with CLL and TP53 aberrations treated with first-line ibrutinib.
Disclosures: This study was funded by the University of Ferrara, Italy, and others. Some authors, including the lead author, declared receiving research support, travel grants, or honoraria for speakers’ bureau or advisory board participation from various sources.
