description Abstract Background and Objective Ibrutinib, an oral Bruton’s tyrosine kinase inhibitor, has demonstrated efficacy as a first-line treatment for chronic lymphocytic leukemia in multiple, phase III, randomized clinical trials. This systematic literature review assessed the clinical effectiveness of ibrutinib in the first-line treatment of chronic lymphocytic leukemia in real-world clinical settings. Methods MEDLINE, EMBASE, and relevant conference websites were searched for articles published in the USA from 1 January, 2014 to 30 June, 2020. Overall survival, progression-free survival, overall response rate, and time to next treatment were summarized. Results This analysis included a total of 12 publications representing data from 112 to 2033 patients from community and academic centers, and the multicenter informCLL registry. Patients were predominantly male (60–99%) with a median age range from 62 to 77 years, and included those with high-risk genomic features (del[17p]: 21–33%; del[11q]: 33%; and unmutated immunoglobulin heavy chain variable gene: 59%). Real-world effectiveness with ibrutinib complemented the efficacy demonstrated in randomized clinical trials. Across various studies, the 12-month overall survival rates ranged from 95% to 96%; 18-month overall survival rates were similarly high (91%). Twelve-month progression-free survival rates ranged from 89% to 93%, and the overall response rate ranged from 71% to 90% across four studies. In the studies that reported time to next treatment, 91% and 87% of patients treated with first-line ibrutinib did not initiate new treatment at 12 months and 24 months, respectively. Conclusions This systematic literature review confirms the benefit of ibrutinib as a first-line treatment in patients with chronic lymphocytic leukemia in real-world clinical settings and is consistent with results from randomized clinical trials, including in patients with high-risk genomic features.
