Summary

This trial will compare amivantamab and lazertinib with osimertinib to see if the first two are more effective in treating NSCLC.

Who is the study for?
This trial is for adults with a specific type of advanced lung cancer (NSCLC) that hasn't been treated before and can't be cured with surgery or radiation. Their tumors must have certain genetic changes (Exon 19 deletions or Exon 21 L858R substitution). They need at least one measurable tumor lesion, no active brain metastases, and no history of severe lung disease.
What is being tested?
The study compares the effectiveness of two treatments: a combination therapy using Amivantamab and Lazertinib versus Osimertinib alone in patients with advanced NSCLC carrying specific genetic mutations. The goal is to see which treatment works better for this condition.
What are the potential side effects?
Possible side effects include allergic reactions to the drugs' ingredients, issues related to infusion such as discomfort or pain at the injection site, potential worsening of lung conditions like pneumonitis, and general side effects from cancer therapies like fatigue, nausea, and skin reactions.

Experimental Treatment
Active Control
Group I: Treatment Arm C (Double-blind): Lazertinib+Placebo OsimertinibExperimental Treatment2 Interventions
Participants will receive lazertinib 240 mg (80\*3) orally once daily plus matching placebo of osimertinib 80 mg orally once daily.
Group II: Treatment Arm A (Open-label): Amivantamab and LazertinibExperimental Treatment2 Interventions
Participants will receive amivantamab 1050 milligram (mg) intravenously (IV) for body weight less than (\<) 80 kilogram (kg) and 1400 mg for body weight greater than or equal to (\>=) 80 kg in 28-day cycles: once weekly in Cycle 1 (with a split dose on Days 1-2), and then every 2 weeks in subsequent cycles. Lazertinib will be administered 240 mg (80\*3) orally once daily.
