No new safety concerns were found. This study provides real-world evidence of the effectiveness and safety of afatinib as first-line therapy for Chinese patients with EGFR mutation-positive advanced NSCLC.

Since 1997, EGFR tyrosine kinase inhibitors (EGFR-TKIs) have evolved from first-generation agents, such as gefitinib, erlotinib, and icotinib, to second-generation agents like afatinib and dacomitinib, now to third-generation agents, including osimertinib, aumolertinib, furmonertinib, befotertinib, rezivertinib, rilertinib, limertinib, lazertinib, mifanertinib for EGFR L858R, sunvozertinib for EGFR exon 20 insertion (20ins), and zorifertinib for EGFR-sensitive mutation with brain metastases. Over the past 30 years, substantial advancements have been made in the comprehensive management of EGFR-mutant NSCLC. This systemic review provides the history of the development of EGFR-TKI therapy for NSCLC from 1997 to 2026, highlighting clinical milestones, emerging therapies, and future directions in this rapidly evolving field.

Cetuximab, a chimeric IgG1 monoclonal antibody anti-EGFR, is the only EGFR-targeted agent approved for HNSCC and has shown efficacy in both locally advanced (in platinum-unfit patients) and recurrent/metastatic (R/M) settings...Irreversible pan-HER tyrosine kinase inhibitors (e.g., afatinib, dacomitinib), dual-target bispecific antibodies such as duligotuzumab (EGFR/HER3), petosemtamab (EGFR/LGR5) or ficerafusp alfa (EGFR/TGF-β) have led to promising preclinical and early-phase clinical activity...While EGFR remains a valid therapeutic target, future efforts must focus on biomarker-driven patient selection and combination strategies to enhance efficacy and durability of response. Ongoing trials will further define the role of emerging anti-EGFR agents and their integration into HNSCC treatment algorithms.

Among older adults, 31 (97%) patients experienced AEs of all grades, and only six patients had grade ≥ 3 AEs with no grade 5 AEs. Afatinib demonstrated comparable therapeutic efficacy and safety in older and non-older adult patients with advanced EGFR-mutant NSCLC.Trial registration: UMIN-CTR identifier (UMIN000024935).

EGFR-TKI-resistant cell lines were established by long-term exposure to gefitinib, afatinib, and osimertinib via the PC9 model. Targeting endoplasmic reticulum (ER) stress pathways alongside immune checkpoint inhibitors may be crucial for overcoming resistance mechanisms identified here. These insights provide a rationale for personalized treatment strategies tailored to the immune-related gene-expression profiles observed in EGFR-TKI-resistant NSCLC models, aiming to enhance therapeutic responses and improve clinical outcomes.

This review provides a comprehensive overview of the evolution of four generations of EGFR tyrosine kinase inhibitors (EGFR-TKIs): first-generation reversible inhibitors such as gefitinib and erlotinib; second- and third-generation irreversible inhibitors, including afatinib, dacomitinib, and osimertinib; and emerging fourth-generation agents, such as amivantamab. Future studies should explore combination therapies, antibody-drug conjugates, and next-generation allosteric inhibitors as promising strategies to overcome resistance. The evolution of EGFR-targeted therapy exemplifies the progress of precision oncology and serves as a basis for designing new paradigms in the management of lung cancer.

After multi-disciplinary treatment, the patient received concurrent chemoradiotherapy with pemetrexed and cisplatin, and achieved partial response. This patient did not receive durvalumab immunoconsolidation therapy for economic reasons...Patients with EGFR S768I/V769L compound mutated NSCLC may benefit from afatinib and osimertinib. Drugs with strong brain penetration capabilities are still needed for patients with S768I/V769L compound mutation to further improve survival outcomes.

MB49 cells were treated in vitro with lentiviral IFNα (LV-IFNα) gene therapy, with/without Afatinib, a pan-ErbB inhibitor, and cell viability and migration assays were performed...No mice in the combination therapy group died of drug toxicity. Our preliminary findings suggest that the ErbB pathway may serve as a clinically significant resistance mechanism to intravesical IFNα gene therapy, and when targeted concurrently, may improve treatment efficacy.

RAF1 is a key, non-redundant vulnerability in KRAS-driven lung adenocarcinoma. Co-targeting ARAF, EGFR, or DDR1 provides no additional therapeutic benefit in established disease. The absence of adverse effects from ARAF co-deletion suggests that RAF1 degraders with partial cross-activity towards ARAF are likely to be safe. These findings provide a strong preclinical rationale for developing RAF1-targeted degradation as a monotherapy for these malignancies.
