The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended expanding the approved use of bosutinib (BOSULIF) to include treatment of patients with newly diagnosed, chronic phase, Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML).
Bosutinib is currently approved in Europe to treat patients with Ph+ CML in chronic, accelerated, or blast phase who have received one or more tyrosine kinase inhibitors and for whom imatinib, nilotinib, and dasatinib are not considered appropriate treatment options.
The CHMP’s opinion on bosutinib will be reviewed by the European Commission (EC). If the EC agrees with the CHMP, the commission will grant a centralized marketing authorization that will be valid in the European Union. Norway, Iceland, and Liechtenstein will make corresponding decisions on the basis of the EC’s decision.
The EC typically makes a decision within 67 days of the CHMP’s recommendation.
The CHMP’s recommendation for bosutinib is based on results from the BFORE trial, which were recently published in the Journal of Clinical Oncology.
The publication included data on 536 patients newly diagnosed with chronic phase CML. They were randomized 1:1 to receive bosutinib (n=268) or imatinib (n=268).
The modified intent-to-treat population included Ph+ patients with e13a2/e14a2 transcripts who had at least 12 months of follow-up. In this group, there were 246 patients in the bosutinib arm and 241 in the imatinib arm.
In the modified intent-to-treat population, the rate of major molecular response at 12 months was 47.2% in the bosutinib arm and 36.9% in the imatinib arm (P=0.02). The rate of complete cytogenetic response was 77.2% and 66.4%, respectively (P<0.008).
In the entire study population, 22.0% of patients receiving bosutinib and 26.8% of those receiving imatinib discontinued treatment—12.7% and 8.7%, respectively, due to drug-related toxicity.
Adverse events that were more common in the bosutinib arm than the imatinib arm included grade 3 or higher diarrhea (7.8% vs 0.8%), increased alanine levels (19% vs 1.5%), increased aspartate levels (9.7% vs 1.9%), cardiovascular events (3% vs 0.4%), and peripheral vascular events (1.5% vs 1.1%).
Cerebrovascular events were more common with imatinib than bosutinib (0.4% and 0%, respectively).
