Neoadjuvant treatment with lazertinib for lung cancer patients with specific mutations

A Phase II, Single-Center, Single-Arm, Prospective Study of Neoadjuvant Lazertinib Therapy in Resectable EGFR-Mutation Positive Lung Adenocarcinoma Patients Detected by Broncho-alveolar Lavage Fluid(BALF) Liquid Biopsy

Phase 2 Interventional Konkuk University Medical Center · NCT05469022

This study is testing if a new lung cancer treatment called lazertinib can help patients with specific mutations feel better and reduce the chances of their cancer coming back after surgery.

What this trial studies

This study evaluates the effectiveness of neoadjuvant lazertinib therapy in patients with resectable non-small cell lung cancer (NSCLC) that have specific EGFR mutations. Patients will receive lazertinib for 9 weeks prior to surgery, followed by additional treatment for those with advanced disease to prevent recurrence. The study also utilizes bronchoalveolar lavage fluid for liquid biopsy to identify EGFR mutations, minimizing the need for invasive tissue biopsies. The goal is to improve outcomes for patients with early-stage lung cancer who are at high risk of recurrence.

Who should consider this trial

Good fit: Ideal candidates include adults aged 19 and older with resectable EGFR mutation-positive NSCLC and no prior treatment with EGFR-TKIs.

Not a fit: Patients with non-resectable tumors or those who have previously received EGFR-TKI treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce recurrence rates in patients with EGFR-mutated lung cancer.

How similar studies have performed: While the efficacy of first-generation EGFR-TKIs has been established, the use of third-generation EGFR-TKIs like lazertinib in this context is novel and has not been fully tested in prior studies.
