Using Lazertinib for Patients with Advanced Lung Cancer After Chemoradiation

A Phase II, Multicenter Study of Lazertinib as Consolidation Therapy in Patients With Locally Advanced, Unresectable, EGFR Mutation Positive Non-Small Cell Lung Cancer (Stage III) Who Have Not Progressed Following Definitive, Platinum-based, Chemoradiation Therapy (PLATINUM Trial)

PHASE2 · Korea University Guro Hospital · NCT05338619

This study is testing if the medication Lazertinib can help people with advanced lung cancer live longer without their cancer getting worse after they finish chemotherapy and radiation.

What this trial studies

This study evaluates the effectiveness of Lazertinib as a consolidation therapy for patients with locally advanced, unresectable non-small cell lung cancer (NSCLC) who have completed definitive platinum-based chemoradiation therapy without disease progression. It is a phase II, open-label, single-arm trial involving 77 participants who will receive Lazertinib orally once daily for up to four years, with regular follow-ups for tumor evaluation and survival assessment. The aim is to determine if Lazertinib can improve progression-free survival in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with locally advanced, unresectable stage III NSCLC who have not experienced disease progression after chemoradiation.

Not a fit: Patients with a history of interstitial lung disease, prior EGFR-TKI therapy, or unresolved toxicity may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly prolong progression-free survival for patients with advanced EGFR-mutant lung cancer.

How similar studies have performed: Previous studies have shown promising results with other EGFR-TKIs like Osimertinib, indicating potential for success with Lazertinib as well.
