What is this trial about?

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

Non‑Small Cell Lung Cancer is a common type of lung cancer. When it has spread beyond the lungs it is called metastatic. Some tumors have genomic driver alterations – specific genetic changes that can be targeted with medicines. The study aims to find the best order of using these medicines to keep the disease from growing for as long as possible.

The trial uses several approved medicines that work on different genetic changes. These include the oral pills Lazcluze, Tafinlar, Lorviqua, Mektovi, OSIMERTINIB, Retsevmo, Alunbrig, KRAZATI, and the infusion drugs OPDIVO, Tecentriq, LIBTAYO, Rybrevant. Some are taken by mouth in tablet or capsule form, while others are given through a vein (intravenous infusion). Each medicine is chosen based on the specific genetic alteration present in the tumor.

Participants are assigned to different sequences of these medicines and are followed with regular check‑ups and scans. The main goal is to measure progression free survival at two years, which means the time before the cancer grows or spreads again. Additional outcomes include overall survival (time alive), objective response rate (how many tumors shrink), duration of response (how long shrinkage lasts), treatment‑related adverse events (side effects caused by the drugs), and health‑related quality of life (how patients feel and function). The study follows each person for several years to collect these data.

The research process

The trial runs in 3 steps – from screening to follow-up. Each step says what happens and what the team monitors.

Investigated drugs

  • Lazertinib

    is an oral medicine that blocks a specific mutant protein that can drive cancer growth in some lung cancers. In the study it is tested to see how well it works alone or in sequence with other drugs.

  • Dabrafenib

    is a pill that targets a mutation in the BRAF gene, which can cause tumor cells to grow. The trial evaluates its effect when given before or after other treatments.

  • Vinorelbine

    is a chemotherapy drug given through an IV. It works by stopping cancer cells from dividing, and the study looks at its role in combination or sequencing with targeted therapies.

  • Nivolumab

    is an IV infusion that helps the immune system recognize and attack cancer cells by blocking a protein called PD‑1. The trial tests how it fits into treatment sequences for lung cancer.

  • Atezolizumab

    is an IV immunotherapy that blocks the PD‑L1 protein, allowing the immune system to fight the tumor. Its position in the treatment order is being examined in the study.

  • Lorlatinib

    is an oral drug that blocks several abnormal proteins (including ALK and ROS1) that drive tumor growth. The study assesses its effectiveness when used early or later in therapy.

What is already known about the treatment

  • Lazertinib

    This drug is taken by mouth as a film‑coated tablet. It is an approved targeted therapy for certain types of non‑small cell lung cancer and is described in many clinical studies. Lazertinib blocks the activity of the mutant EGFR protein that drives tumor growth. It belongs to the class of EGFR tyrosine‑kinase inhibitors.

  • Dabrafenib

    Dabrafenib is an oral capsule that patients swallow. It is an approved treatment for cancers with a BRAF V600 mutation and is widely studied in the literature. The medicine blocks the mutated BRAF protein, stopping signals that tell cancer cells to multiply. It is classified as a BRAF inhibitor.

  • Vinorelbine

    Vinorelbine is given by intravenous infusion of a solution. It is a chemotherapy drug that has been used for many years in lung cancer and is well documented in medical texts. It works by interfering with the formation of microtubules, which are needed for cancer cells to divide. It belongs to the class of vinca alkaloid antineoplastics.

  • Nivolumab

    Nivolumab is administered as an intravenous infusion of a sterile solution. It is an approved immune‑checkpoint inhibitor used for several cancers, including lung cancer, and is supported by extensive clinical research. The antibody blocks the PD‑1 protein on immune cells, helping the body’s own defenses attack the tumor. It is classified as a PD‑1 inhibitor.

  • Atezolizumab

    Atezolizumab is given by intravenous infusion of a solution. It is an approved immunotherapy for lung cancer and other tumors and has a strong evidence base in many trials. It binds to the PD‑L1 protein, preventing it from turning off immune cells that can kill cancer. It is a PD‑L1 inhibitor.

  • Lorlatinib

    Lorlatinib is taken orally as a film‑coated tablet. It is an approved drug for ALK‑positive lung cancer and is well described in recent studies. The medicine blocks the ALK and ROS1 proteins that drive tumor growth. It belongs to the class of ALK/ROS1 tyrosine‑kinase inhibitors.

Investigated diseases

Non‑small cell lung cancer - Non‑small cell lung cancer (NSCLC) is a cancer that starts in the lining of the larger airways of the lungs. It grows as a solid tumor that can invade nearby lung tissue and the chest wall. Over time the tumor may spread through the lymphatic system to nearby lymph nodes and later to distant organs such as the brain, liver, or bones. The disease often develops gradually, with symptoms appearing as the tumor enlarges and spreads.
