Conditions

Non-Small Cell Lung Cancer (NSCLC)

Brief summary

Importance: EGFR tyrosine kinase inhibitors (EGFR-TKIs) and PD-1/PD-L1 immune checkpoint inhibitors are widely used in the treatment of non-small cell lung cancer (NSCLC). However, the safety profile of their combination-particularly the risk of interstitial pneumonitis (IP)-remains unclear. Objective: To evaluate the incidence and risk of interstitial pneumonitis associated with EGFR-TKIs when combined with PD-1/PD-L1 inhibitors, using real-world pharmacovigilance data. Design, Setting, and Participants: This retrospective observational study analyzed adverse event reports from the FDA Adverse Event Reporting System (FAERS) between January 1, 2015, and December 31, 2024. A total of 67,818 NSCLC cases were included, categorized by treatment with EGFR-TKIs, PD-1/PD-L1 inhibitors, combined therapy, or the other therapies. Exposure: NSCLC patients receiving EGFR-TKI PD-1/PD-L1 inhibitors, combined therapy, or the other therapies were compared to those not receiving such treatment. Main Outcome and Measures: Incidence of reported interstitial pneumonitis and adjusted odds ratios (aORs) derived from multivariable logistic regression analyses.

Interventions

epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs)-including gefitinib, erlotinib, afatinib, and osimertinib

ICIs such as nivolumab, pembrolizumab, and atezolizumab-targeting the programmed cell death 1 (PD-1) or its ligand (PD-L1)

Inclusion criteria

* Patients with non-small cell lung cancer (NSCLC). * Received at least one EGFR-TKI (gefitinib, erlotinib, afatinib, osimertinib). Or received at least one PD-1/PD-L1 inhibitor (nivolumab, pembrolizumab, atezolizumab, durvalumab). Or received combination therapy with both EGFR-TKIs and PD-1/PD-L1 inhibitors. Or received the other therapies. * Cases reported in the FDA Adverse Event Reporting System (FAERS) between January 1, 2015, and December 31, 2024.

Exclusion criteria

* Non-NSCLC Indications: Cases not related to NSCLC (e.g., other cancer types). * Incomplete Treatment Data: Patients with missing or unclear treatment exposure information (e.g., use of unrelated therapies). * Duplicate Reports: Duplicate adverse event reports were excluded.
