Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The "PACIFIC" trial confirmed that the consolidation therapy with durvalumab in patients with stage III, locally advanced, unresectable NSCLC that had not progressed after definitive platinum-based chemoradiation therapy improved the progression-free survival (PFS) by about 17 months. However, in PACIFIC, no significant differences between durvalumab and placebo were observed in PFS. Unmet need remains in development of successful consolidation therapy following chemoradiation therapy in patients with EGFR-mutant stage III unresectable NSCLC.

A recent "ADAURA" study showed that Osimertinib as an adjuvant therapy after surgery significantly prolonged disease-free survival in EGFR mutation-positive patients. Lazertinib, like Osimertinib, is a third-generation EGFR TKI agent and has shown excellent anticancer effects in preclinical studies and in early clinical settings. Based on these results of the 3rd generation EGFR TKI, Lazertinib, it is expected that there is a clinical benefit Lazertinib as consolidation therapy.

This study aims to investigate the clinical benefits of Lazertinib (Trade name: LECLAZA Tab) consolidation therapy for patients with EGFR mutation-positive, unresectable stage III NSCLC after definitive platinum-based chemoradiation therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is designed as a prospective, open-label, single-arm, multicenter, phase II, investigator-initiated trial. A total of 77 patients will participate in the study who have undergone definitive platinum-based concurrent chemoradiation therapy and have no disease progression. Patients are to be enrolled within 1 to 42 days after concurrent chemoradiation therapy and to be administrated with lazertinib 240mg oral once daily until disease progression, or unacceptable toxicity. Patients will visit every 8 weeks and perform CT/MRI tumor evaluation by investigator, and will be followed up for survival every 3 months by phone thereafter. Patients will be followed up till maximum of appropriately 4 years of which 3 years since the last patient enrollment must be.
