Background:
The tyrosine kinase inhibitors (TKIs) asciminib, bosutinib, dasatinib, imatinib, nilotinib, and ponatinib have been approved for chronic myelogenous leukemia (CML) therapy. However, pharmacovigilance reports associated with these drugs are neither consistent nor homogenous, with reports of pulmonary toxicity, which could limit their utilization. To better clarify TKIs' pulmonary risk, we used the European database EudraVigilance to conduct a study on adverse events suspected to be caused by the TKIs asciminib, bosutinib, dasatinib, imatinib, nilotinib, and ponatinib when used for CML therapy.
Methods:
Suspected adverse reactions to TKIs in the EudraVigilance database (2020-2024) coming from European countries and the United Kingdom were analyzed and compared through a disproportionality analysis.
Results:
The most frequent alerts concerned the respiratory disorders "pleural effusion" (PE) and "pulmonary arterial hypertension" (PAH) in relation to dasatinib and bosutinib use. Among the TKIs, the prescription of dasatinib is associated with a higher occurrence of PE and PAH, while the prescription of bosutinib induces PE at a minor frequency that nonetheless carries a significant risk for PAH, occurring more often in women.
Conclusions:
The results indicate that respiratory disorders induced by the TKIs dasatinib and bosutinib need to be diagnosed in a timely manner, and suggest that caution should be taken when prescribing these TKIs to patients affected by CML and pulmonary comorbidities.
Insights
Dasatinib and bosutinib, tyrosine kinase inhibitors (TKIs) for chronic myelogenous leukemia (CML), are linked to significant pulmonary risks like pleural effusion and pulmonary arterial hypertension. Early diagnosis and cautious prescribing are crucial for patients with CML and lung conditions.
Area of Science:
- Pharmacology
- Oncology
- Pulmonology
Background:
- Tyrosine kinase inhibitors (TKIs) are vital for chronic myelogenous leukemia (CML) treatment.
- Existing pharmacovigilance data on TKI-associated pulmonary toxicity is inconsistent.
- Pulmonary adverse events may limit the clinical utility of approved TKIs.
Purpose of the Study:
- To investigate the pulmonary risk profile of specific TKIs used in CML therapy.
- To analyze adverse event reports for asciminib, bosutinib, dasatinib, imatinib, nilotinib, and ponatinib.
- To clarify the association between TKIs and respiratory disorders.
Main Methods:
- Utilized the European database EudraVigilance for adverse event data (2020-2024).
- Focused on reports from European countries and the United Kingdom.
- Employed disproportionality analysis to compare TKI-related adverse reactions.
Main Results:
- Dasatinib and bosutinib showed the most frequent alerts for pleural effusion (PE) and pulmonary arterial hypertension (PAH).
- Dasatinib prescription correlated with higher occurrences of PE and PAH.
- Bosutinib use also presented a significant risk for PAH, particularly in women, despite lower PE frequency.
Conclusions:
- Timely diagnosis of TKI-induced respiratory disorders, especially from dasatinib and bosutinib, is essential.
- Caution is advised when prescribing these TKIs to CML patients with pre-existing pulmonary conditions.
- Further monitoring for pulmonary toxicities associated with TKIs is warranted.
