Levels of Evidence
GRADE ⊕⊖⊖⊖a,b,c We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect.
1: The first cohort of participants will receive intravenous (IV) infusions of Amivantamab 140 milligram (mg) as monotherapy. Each subsequent cohort will receive IV infusions of Amivantamab at increased dose level. Dose escalation will continue until maximum tolerated dose is reached or all planned doses are administered. Participants will receive IV infusion of Amivantamab once weekly during cycle 1 and once every 2 weeks during subsequent cycles (duration of each treatment cycle is 28 days). Participants will receive lazertinib and Amivantamab on Cycle 1 Day 1 (C1D1) prior to initiation of Amivantamab (C1D1) at predefined dose levels, based upon observed safety and protocol defined criteria. Lazertinib will be administered daily thereafter, on 28-day Amivantamab treatment cycle. In Chemotherapy Combination Cohort, participants will receive Amivantamab, administered on a 21-day cycle, in combination with standard of care carboplatin and pemetrexed.; 2: Participants will receive IV infusion of Amivantamab as monotherapy at Phase 2 dose (RP2D) regimen or in combination lazertinib at the recommended Phase 2 combination dose (RP2CD) regimen as determined in Part 1. The purpose of dose expansion is to further evaluate safety, tolerability, pharmacokinetic, and to assess preliminary efficacy in monotherapy and combination therapy cohorts.; 3: Participants will receive IV infusion of Amivantamab as monotherapy at Phase 2 dose (RP2D) regimen or in combination lazertinib at the recommended Phase 2 combination dose (RP2CD) regimen as determined in Part 1. With EGFR Exon20ins mutation and previous platinum-based chemotherapy; 4: Participants will receive IV infusion of Amivantamab as monotherapy at Phase 2 dose (RP2D) regimen or in combination lazertinib at the recommended Phase 2 combination dose (RP2CD) regimen as determined in Part 1. With EGFR Exon20ins mutation and previous platinum-based chemotherapy with ≥3 disease assessments at clinical cutoff
