Plain English summary of protocol

Background and study aims
NSCLC is the most common type of lung cancer. NSCLC may occur due to mutations (changes) in many genes including mesenchymal-epithelial transition (MET) and EGFR. Although treatment options are available only a few patients respond to the treatment or cancer can come back after treatment. Drugs that target EGFR to attack cancer cells may be an effective way to destroy them. The study aims to assess the effectiveness of the combination of amivantamab and lazertinib as first-line treatment and combination of amivantamab and chemotherapy as second-line treatment in participants with NSCLC with specific mutation in the EGFR gene.

Who can participate?
Participants with NSCLC, with changes (mutation) in EGFR gene.

What does the study involve?
The study will include the following phases:
1.Screening Phase (up to 28 days): Participants aged 18 years or above will be screened.
2.Treatment Phase (until end of treatment): Participants will be put into one of the2 cohorts:
Cohort 1-Includes participants who have not received any prior cancer therapy.
Participants will receive amivantamab as an injection under the skin (SC) along withlazertinib orally according to the treatment schedule.
Cohort 2- Includes second-line participants who have progressed on or after EGFR-TKI cancer therapy.
Participants will receive amivantamab as SC injection along with standardchemotherapy (carboplatin and pemetrexed) by injection into a vein as pertreatment schedule.

Participants will receive amivantamab as SC injection along with standardchemotherapy (carboplatin and pemetrexed) by injection into a vein as pertreatment schedule.
3.Follow-up Phase: Participants will be followed up to monitor their overall health until theend of study, death, progression of the disease, or withdrawal of consent, whichever comesfirst.

The UK will participate in Cohort 1 only.

What are the possible benefits and risks of participating?
Based on scientific theory, taking amivantamab with lazertinib combination may help treat NSCLC. However, this cannot be guaranteed because amivantamab is still under investigation as a treatment, and it is not known whether subcutaneous amivantamab and lazertinib combination will work. Participants may experience some benefit from participation in the study that is not due to receiving amivantamab, but due to regular visits and assessments monitoring overall health. Participation may help other people with NSCLC in the future. Participants may have side effects from the drugs or procedures used in this study that may be mild to severe and even life-threatening, and they can vary from person to person. The most common, known risks are - administration-related reactions (ARRs); rash-related AEs, paronychia (tender, swollen skin around the nails); oral mucositis (mouth sores); pulmonary toxicity (lung inflammation or damage); liver chemistry abnormalities; cardiac adverse events; diarrhea; venous thromboembolic event (VTE; blood clots in veins); paresthesia (tingling or numbness); ocular toxicity (eye problems). The participant information sheet and informed consent form, which will be signed by every participant agreeing to participate in the study, includes a detailed section outlining the known risks to participating in the study. Not all possible side effects and risks related to amivantamab and lazertinib combination are known at this moment. During the study, the sponsor may learn new information about amivantamab and lazertinib combination. The study doctor will tell participants as soon as possible about any new information that might make them change their mind about being in the study, such as new risks. To minimise the risk associated with taking part in the study, participants are frequently reviewed for any side effects and other medical events. Participants are educated to report any such events to their study doctor who will provide appropriate medical care. Any serious side effects that are reported to the sponsor are thoroughly reviewed by a specialist drug safety team. There are no costs to participants to be in the study. The sponsor will pay for the study drug and tests that are part of the study. The participant will receive reasonable reimbursement for study-related costs (e.g., travel/parking costs).

Scientific titleA phase 2b, open-label, two-cohort study of subcutaneous amivantamab in combination with lazertinib as first-line treatment, or subcutaneous amivantamab in combination with platinum-based chemotherapy as second-line treatment, for common EGFR-mutated locally advanced or metastatic non-small cell lung cancer
Study acronymCOPERNICUS
Study objectivesThe primary objective of the trial is to assess the effectiveness of the combination of amivantamab and lazertinib and the combination of amivantamab and chemotherapy in participants with non-small cell lung cancer (NSCLC; a type of lung cancer with a change [mutation] in the EGFR gene*) who have a specific mutation in the EGFR gene.

*Cell surface protein that binds to epidermal growth factor. Changes (mutations) in this gene cause lung cancer.

The secondary objectives for this trial are:
1. To assess the safety of amivantamab (in both Cohorts) and lazertinib (in Cohort 1 only) and how well participants can tolerate this treatment.
2. To assess if the treatment works, how many people respond to it, and how long the response lasts.
