EGFR-mutant Non-small Cell Lung Cancer

This national multicenter, randomized controlled clinical trial evaluates the safety and efficacy of consolidative stereotactic radiotherapy in patients with advanced EGFR-mutant non-small cell lung cancer who have oligo-residual disease after four cycles of first-line treatment with third-generation EGFR-TKI plus platinum-based pemetrexed chemotherapy. Eligible participants will be randomized 1:1 to continue third-generation EGFR-TKI plus pemetrexed maintenance therapy alone or to receive stereotactic radiotherapy to all oligo-residual lesions in addition to the same maintenance therapy. The primary endpoint is progression-free survival.

This first-in-human, Phase 1/2, multicenter, open-label, non-randomized study evaluates the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of VRN110755, a highly selective oral epidermal growth factor receptor (EGFR) inhibitor, in patients with EGFR-mutant non-small cell lung cancer (NSCLC). The study includes a Phase 1a dose-escalation portion, a Phase 1b dose-expansion portion, and a Phase 2 evaluation. The study is designed to determine the maximum tolerated dose and recommended Phase 2 dose of VRN110755 and to evaluate preliminary and confirmatory antitumor activity in patients with EGFR-mutant NSCLC, including patients with acquired resistance following EGFR tyrosine kinase inhibitor therapy.

This study is a prospective, single-arm, exploratory clinical research aimed at evaluating the efficacy and safety of lucetamab in combination with leucovorin in the conversion therapy of locally advanced potentially resectable EGFR mutation-positive non-small cell lung cancer, providing more robust clinical evidence for the improvement of treatment modalities for EGFR-mutated locally advanced NSCLC. At the same time, it seeks to identify biomarkers that can predict the therapeutic effect of the combination of lucetamab and leucovorin, offering more precise guidance for the selection of clinical treatment plans and enabling patients to receive the optimal treatment regimen.
