1337P - Real-world utilization and outcomes of dacomitinib as first-line therapy in Asian patients with advanced EGFR mutation–positive NSCLC: An interim analysis of the ARIA study
- Lin Wu (Changsha, China)
Abstract
Background
Dacomitinib, a second-generation, irreversible tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR), provided statistically significant progression-free survival improvement over gefitinib in treatment-naive patients with advanced
Methods
This longitudinal, multicenter cohort study collected prospective and retrospective data from patients with advanced
Results
300 patients from China (n=262), India (n=24), and Malaysia (n=14) were enrolled and included in the analysis. Starting dose was 30 mg once daily (QD) in 159 patients (53%), 45 mg QD in 138 (46%), and other doses in 3 (1%). As of Jan 31, 2023, 81 patients (27.0%) had dose decreases, 13 (4.3%) dose increases, 35 (11.7%) interruptions, and 107 (35.7%) permanently discontinued dacomitinib. Six (2.0%) permanent treatment discontinuations were due to treatment-related toxicities. 1L dacomitinib safety and treatment outcomes are shown in the table. Safety and treatment outcomes of 1L dacomitinib 1L, first line; IQR, interquartile range; ITT, intention to treat; NR, not reached; rwPFS, real-world progression-free survival; TRAE, treatment-related adverse event; TTF, time to treatment failure. a Calculated using the Kaplan-Meier method to obtain 95% confidence interval.
ITT population Total (N=300) 13.1 (11.8) 121 (40.3) 74 (24.7) 65 (21.7) 43 (14.3) 21.4 (17.3-35.9) 25.3 (20.1-NR)
Conclusions
To our knowledge, this is the largest RW study conducted for dacomitinib. Interim analysis shows efficacy of 1L dacomitinib; safety data in the RW setting were generally consistent with dacomitinib’s known safety profile. These results support 1L dacomitinib use in patients with advanced
