Study of zoldonrasib with daraxonrasib, pembrolizumab and chemotherapy in patients with RAS G12D-mutant non-small cell lung cancer

2 1 1 1

What is this study about?

This study focuses on patients with Non-Small Cell Lung Cancer (NSCLC) that has a specific genetic change called RAS G12D mutation. The study will test new treatments using combinations of different medications including zoldonrasib (RMC-9805) and daraxonrasib (RMC-6236), together with pembrolizumab and standard chemotherapy drugs (cisplatin, carboplatin, and pemetrexed).

The main purpose of this research is to determine if these drug combinations are safe to use and to find the right dose that works best for patients. The medications will be given in different ways – some as tablets taken by mouth, while others will be given through an infusion into a vein.

During the study, doctors will monitor patients’ health closely and check how well the treatment is working by looking at changes in their cancer. They will also study how the medications move through the body and how long the beneficial effects of the treatment last. The study will continue for approximately two years.

1 Initial evaluation

Your eligibility for the study will be assessed based on specific criteria, including confirmation of RAS G12D mutation in your non-small cell lung cancer (NSCLC)

Medical tests will be performed to evaluate your organ function and measure existing tumors

2 Treatment assignment

You will be assigned to receive one of the following treatment combinations:

Option 1: RMC-9805 with pembrolizumab

Option 2: RMC-9805 and daraxonrasib with pembrolizumab

Option 3: RMC-9805 with pembrolizumab and chemotherapy (cisplatin or carboplatin with pemetrexed)

Option 4: RMC-9805 and daraxonrasib with pembrolizumab and chemotherapy

3 Treatment administration

Some medications will be given as infusions at the clinic

Some medications will be taken as tablets at home

Your treatment will continue as long as it is safe and effective

4 Monitoring

Regular blood tests will measure medication levels in your body

Your tumor response will be evaluated through imaging tests

Side effects and changes in your health will be monitored throughout the study

Your vital signs and laboratory test results will be regularly checked

5 Study duration

The study is expected to run from November 2025 to February 2027

Your participation duration will depend on how your body responds to the treatment

Who Can Join the Study?

  • You must be at least 18 years old
  • You must have non-small cell lung cancer (NSCLC) with a specific genetic change called RAS-G12D mutation
  • You must either have received previous cancer treatments or be unable to receive standard treatment options
  • You must have at least one tumor that can be measured by medical imaging tests
  • Your body organs must be working well enough, including:
    • Bone marrow (where blood cells are made)
    • Liver (organ that helps clean toxins from body)
    • Kidneys (organs that filter blood)
    • Normal blood clotting ability

Who Cannot Join the Study?

  • Previous treatment with any RMC-9805 or RMC-6236 therapy
  • Active brain metastases (cancer that has spread to the brain) or spinal cord compression that is not treated and stable
  • History of other cancers within 3 years before starting the study, except for successfully treated non-melanoma skin cancer or cervical cancer in situ (early-stage cancer)
  • Serious heart conditions, including:
    • Heart attack within the last 6 months
    • Unstable chest pain
    • Severe heart rhythm problems
  • Active autoimmune disease (condition where immune system attacks healthy cells) requiring systemic treatment
  • Active infection requiring treatment, including hepatitis B, hepatitis C, or HIV
  • Pregnant or breastfeeding women
  • Known allergies or severe reactions to the study medications or their components
  • Any medical condition that, in the opinion of the study doctor, would make it unsafe to participate in the study

Trial locations

RMC-9805 is an investigational medication being studied for treating non-small cell lung cancer (NSCLC) in patients with specific RAS G12D mutations. This is a new drug that targets specific genetic changes in cancer cells.

RMC-6236 is another investigational medication that works together with RMC-9805 to treat non-small cell lung cancer. It is being tested to see if the combination provides better results for patients with RAS G12D mutations.

Pembrolizumab is an immunotherapy medication that helps the body’s immune system fight cancer cells. It works by blocking certain proteins that can prevent immune cells from attacking cancer.

The trial also includes chemotherapy medications that are commonly used to treat cancer by killing rapidly dividing cells. These medications are used in combination with the other treatments mentioned above.

Lung Cancer – A disease that begins in the lungs when cells grow out of control and form tumors. It typically starts in the cells lining the bronchi and parts of the lung such as the bronchioles or alveoli. The abnormal cells continue to grow and can spread to nearby tissues or other parts of the body. Lung cancer often develops slowly over many years, with changes occurring in the lung tissue before actual tumors form. Early in the disease, people may not notice any symptoms as the changes are happening at a cellular level. As the disease progresses, it can cause breathing difficulties, persistent cough, and changes in breathing patterns.
