What is this trial about?

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

This study investigates treatments for Metastatic Squamous Non-Small Cell Lung Cancer, which is a type of lung cancer that has spread to other parts of the body. The purpose of the study is to compare the effectiveness of a drug called V940 when used alongside other therapies compared to a placebo. The experimental treatment involves combining V940 with pembrolizumab, an immunotherapy, and a chemotherapy regimen consisting of carboplatin and either paclitaxel albumin-bound, paclitaxel, or docetaxel. These medications are delivered through an intravenous infusion, which is a method of delivering fluids or medicine directly into a vein.

Participants in the study may also receive mRNA-4157, which is an intramuscular injection, meaning it is administered directly into a muscle. The study is designed as a randomized and double-blind trial, which means participants are assigned to different treatment groups by chance, and neither the participants nor the researchers know which specific treatment is being given during the course of the study. This approach helps ensure that the results are as objective as possible.

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

    Study participation and treatment assignment

    After joining the study, a treatment group is assigned through a process called randomization, which means the group is chosen by chance.

    The study is double-blind, meaning neither the patient nor the medical staff knows which specific treatment is being administered during the trial.

  2. Step 2

    Administration of combination therapy

    Treatment involves receiving a combination of immunotherapy (a type of medicine that helps the immune system fight cancer), chemotherapy (medicine used to kill cancer cells), and V940.

    The V940 component is either the active medication or a placebo, which is an inactive substance used for comparison.

  3. Step 3

    Medication details

    The pembrolizumab is administered as an intravenous infusion (medicine delivered directly into a vein) at a dose of 400 mg.

    The platinum chemotherapy part of the treatment involves an intravenous infusion of either carboplatin at a dose of 900 mg or paclitaxel at a dose of 200 mg/m2 (milligrams per square meter of body surface area).

    Other possible treatments include paclitaxel albumin-bound at a dose of 100 mg/m2 via intravenous infusion or docetaxel at a dose of 75 mg/m2 via intravenous infusion.

    The medication mRNA-4157 may be administered via intramuscular use (an injection into the muscle) at a dose of 1 mg.

  4. Step 4

    Monitoring and evaluation

    The effectiveness of the treatment is monitored by measuring progression-free survival, which is the length of time during and after treatment that the cancer does not grow or spread.

    The overall survival, which is the total length of time from the start of the treatment that the patient remains alive, is also tracked.

    Medical professionals monitor for adverse events, which are any side effects or medical problems that occur during the study.

What is already known about the treatment

  • Paclitaxel albumin-bound

    This medication is a chemotherapy drug administered through an intravenous infusion into the bloodstream. It is an established treatment used to manage various types of cancer, including certain lung cancers. At a molecular level, it works by interfering with the internal structure of cancer cells, preventing them from dividing and growing. It belongs to a class of drugs known as taxanes.

  • Paclitaxel

    This is a chemotherapy agent delivered to the patient via intravenous infusion. It is widely used in medical practice to treat several types of solid tumors. The drug works by stabilizing the internal framework of cells, which stops cancer cells from multiplying. It is classified as a taxane-based chemotherapy medication.

  • Docetaxel

    This medication is a type of chemotherapy given through an intravenous infusion. It is currently used in clinical settings to treat various cancers, such as breast, lung, and prostate cancer. Its mechanism involves blocking the process that allows cancer cells to divide by affecting their internal structural proteins. It is categorized as a taxane.

  • Pembrolizumab

    This drug is administered as an intravenous infusion using a concentrated solution. It is a well-known immunotherapy used to treat many types of cancer by helping the immune system recognize and attack tumor cells. It works by blocking specific proteins on immune cells that normally prevent them from attacking cancer. This medication is classified as an immune checkpoint inhibitor.

  • mRNA-4157

    This is an experimental therapeutic administered via an intramuscular injection into the muscle. It is currently being studied in clinical trials for its potential to prevent cancer recurrence. The drug uses messenger RNA technology to teach the body's immune system to recognize and target specific cancer markers. It is classified as a personalized cancer vaccine.

  • Carboplatin

    This medication is a chemotherapy drug administered through intravenous infusion. It is a standard treatment used for many different types of cancer to slow down disease progression. It works at the molecular level by damaging the DNA of cancer cells, which prevents them from reproducing. It is categorized as a platinum-based chemotherapy agent.

Investigated diseases

Non-small cell lung cancer stage IV - This is a type of lung cancer that begins in the cells that make up the airways and lung tissue. In stage IV, the cancer has spread from its original location in the lung to other parts of the body, such as the liver, bones, or the other lung. The disease progresses as cancer cells continue to multiply and move through the bloodstream or lymphatic system to distant organs. As the cancer grows, it can interfere with the normal functions of the affected organs. The progression is characterized by the increasing presence of tumor cells throughout various systems in the body.
