What is this trial about?

A plain-language summary of the goals, design and what participants do

This study focuses on patients with Non-small cell lung cancer (NSCLC) who have a specific genetic change called EGFR exon20 insertion mutation. The cancer in these patients has spread to other parts of the body (stage IV) or has come back after previous treatment. The study will test a combination of two medications: amivantamab (also known as JNJ-61186372) and pemetrexed.

The purpose of this study is to determine how well this combination treatment works and how safe it is for patients who cannot receive standard platinum-based chemotherapy. During the study, patients will receive amivantamab through an injection under the skin and pemetrexed through an intravenous infusion (a slow injection into a vein). The treatment may continue for up to 24 months.

The study will track how the cancer responds to treatment by taking regular scans to measure tumors. The researchers will also monitor how long patients live without their cancer getting worse and check for any side effects from the treatment. This study is particularly meant for patients who have not received any previous systemic treatment for their cancer and who cannot receive standard platinum-based chemotherapy due to certain health conditions.

The research process

The trial runs in 4 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial assessment

    You will undergo tests to confirm non-small cell lung cancer (NSCLC) with specific genetic changes in the EGFR exon20 gene

    Your doctor will perform tests to verify your eligibility, including blood tests to check bone marrow, liver, and kidney function

    A pregnancy test will be required for female patients of childbearing potential

  2. Step 2

    Treatment preparation

    Your doctor will confirm that you have not received any previous systemic treatment

    Your physical condition will be assessed using the ECOG Performance Status scale (ranging from 0-2)

    If you have brain metastases, imaging will confirm they are stable for at least two weeks

  3. Step 3

    Treatment administration

    You will receive two medications: amivantamab and pemetrexed

    Amivantamab will be given as an injection under the skin

    Pemetrexed will be administered through an intravenous infusion

    Regular imaging scans will monitor your response to treatment

  4. Step 4

    Monitoring period

    Your response to treatment will be measured using specialized imaging criteria (RECIST 1.1)

    Regular assessments will track how long the treatment remains effective

    Blood tests and physical examinations will continue throughout the treatment period

    The study will continue until September 2028

Investigated drugs

  • Amivantamab

    is a targeted therapy medication that works specifically against lung cancer cells with certain genetic changes (EGFR exon20 insertion mutations). It is an antibody that attaches to specific proteins on cancer cells to help stop them from growing and spreading. This medication is given through an intravenous infusion (through a vein).

  • Monochemotherapy

    refers to the use of a single chemotherapy medication to treat cancer. In this case, it is combined with amivantamab to treat non-small cell lung cancer in patients who cannot receive platinum-based chemotherapy. The chemotherapy works by killing fast-growing cancer cells or stopping them from dividing.

What is already known about the treatment

Amivantamab – A bispecific antibody medication administered through intravenous infusion, specifically designed for treating non-small cell lung cancer (NSCLC) with EGFR exon20 insertion mutations. This targeted therapy works by simultaneously binding to both EGFR and MET receptors on cancer cells, blocking their signaling pathways that promote tumor growth. It belongs to the class of targeted immunotherapies and represents a significant advancement in precision medicine for patients who are unable to receive platinum-based chemotherapy, offering a more personalized approach to lung cancer treatment.

Investigated diseases

Non-small cell lung cancer (NSCLC) - A type of lung cancer that begins in the epithelial cells of the lung tissue. It develops when cells in the lungs begin to grow uncontrollably, forming tumors that can spread to other parts of the body. NSCLC typically grows and spreads more slowly than small cell lung cancer. The disease usually starts in the cells that line the airways of the lungs, gradually affecting normal lung function. NSCLC accounts for the majority of all lung cancer cases and can occur in different parts of the lung tissue.
