Abstract
ABSTRACT Background Epidermal Growth Factor Receptor/ Anaplastic Lymphoma Kinase Tyrosine kinase inhibitors (EGFR/ALK TKIs) may provoke fatal interstitial pneumonitis (IP). The study was conducted to characterise the main characteristics of EGFR/ALK TKI-induced IP and identify factors associated with death. Research design and methods A disproportionality analysis was conducted using Vigibase, the World Health Organization pharmacovigilance database. Clinical features of patients with EGFR/ALK-TKI-related IP were compared between the fatal and non-fatal groups. Results A total of 3355 EGFR/ALK-TKI-IP events were identified, over half of them from Asia (57.47%) and mostly the aged (63.21%). Osimertinib appeared the strongest IP association. The median time to onset (TTO) was 40 (interquartile range [IQR] 16-84) days. There were significant differences between the fatal and non-fatal groups in terms of reporting year and TKI regimens (P < 0.05). The fatality rate of erlotinib-induced IP was the highest (35.54%). Conclusion Our study showed that EGFR/ALK TKIs were associated with IP that had a high fatality rate and tend to occur earlier in fatal cases. It is necessary to raise awareness of IP surveillance when EGFR/ALK TKIs were administered.
