Conditions
Brief summary
The main purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of Lazertinib when given orally to participants with epidermal growth factor receptor single activating mutation positive (EGFRm+) locally advanced or metastatic Non Small Cell Lung Cancer (NSCLC).
Detailed description
One-third of all cancer deaths worldwide are still caused by lung cancer and non-small-cell lung cancer (NSCLC). Lazertinib is an oral, highly potent, mutant-selective and irreversible epidermal growth factor receptor (EGFR) Tyrosine kinase inhibitor (TKIs) targets both the T790M mutation and activating EGFR mutations while sparing wild type-EGFR. The study will be conducted in participants with EGFR mutation positive advanced non-small cell lung cancer (NSCLC). Study Parts A, B, and C are sponsored by Yuhan Corporation under protocol identifier YH25448-201 (ClinicalTrials.gov Identifier: NCT03046992), and Study Part D is sponsored by Janssen Research and Development, LLC under protocol identifier 73841937NSC2001. In Part D, Lazertinib will be given to participants outside Korea, including Caucasians, in order to evaluate safety, tolerability, efficacy (including tumor response) and Pharmacokinetics (PK) in participants outside of Korea. The duration of this study will be up to 2 years. Study treatment should be held in all participants with suspected (symptomatic) or documented severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive disease, until recovery from all infection related symptoms, and documented to be negative for SARS-CoV-2.
Interventions
Participants will receive Lazertinib tablets once daily.
