What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new treatment for patients with colorectal cancer. The treatment combines two drugs that work together to block cancer growth and prevent its spread. One of the drugs has shown promise in treating other types of cancer as well.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What safety data exists for the treatment MRTX849 + Cetuximab for colorectal cancer?

Cetuximab, used in combination with other drugs for colorectal cancer, has been associated with skin reactions like rashes and nail changes, which are common but usually manageable. Serious side effects are rare, but some patients may experience severe skin reactions, diarrhea, nausea, or fatigue. Monitoring and managing these side effects are important for patient safety.12345

What makes the drug MRTX849 + Cetuximab unique for colorectal cancer?

The combination of MRTX849 (Adagrasib) and Cetuximab is unique because it targets specific genetic mutations in colorectal cancer, such as KRAS mutations, which are not addressed by standard treatments. This approach offers a more personalized treatment option for patients with these specific genetic profiles.12367

What data supports the effectiveness of the drug combination MRTX849 and Cetuximab for colorectal cancer?

Cetuximab, when combined with FOLFIRI, has been shown to improve survival and response rates in patients with metastatic colorectal cancer who have KRAS wild-type tumors. Additionally, cetuximab retreatment has provided clinical benefits for patients who previously responded well to it.238910

Are You a Good Fit for This Trial?

This trial is for adults with advanced colorectal cancer who have the KRAS G12C mutation. They must have had one prior treatment with specific chemotherapy and shown disease progression afterwards. People can't join if they've had brain metastases, previous treatments targeting KRAS G12C, or anti-EGFR antibody therapies.

Inclusion Criteria

My colorectal cancer has a specific KRAS G12C mutation.
My advanced colorectal cancer progressed after first-line chemotherapy.

Exclusion Criteria

I have been treated with an anti-EGFR antibody before.
I have been treated with a drug targeting the KRAS G12C mutation.
I have active cancer spread to my brain.

What Are the Treatments Tested in This Trial?

Interventions

  • Cetuximab
  • FOLFIRI Regimen
  • mFOLFOX6 Regimen
  • MRTX849
Trial Overview The study compares MRTX849 combined with cetuximab to standard chemotherapies (mFOLFOX6 or FOLFIRI) in second-line treatment of colorectal cancer with a specific mutation. It's an open-label trial where patients are randomly assigned to either the new drug combo or standard chemo.

Published Research Related to This Trial

Cetuximab, a monoclonal antibody targeting the EGFR, has been approved for first-line treatment of KRAS mutation-negative metastatic colorectal cancer (mCRC) in combination with FOLFIRI, showing significant improvements in progression-free survival and overall survival.
The combination of cetuximab with FOLFIRI also resulted in higher objective response rates compared to FOLFIRI alone, making it a valuable treatment option for patients with EGFR-expressing, KRAS wild-type mCRC.
Cetuximab: a guide to its use in combination with FOLFIRI in the first-line treatment of metastatic colorectal cancer in the USA.Lyseng-Williamson, KA.[2021]
In patients with metastatic colorectal cancer (mCRC) who have KRAS wild-type tumors, adding cetuximab to the FOLFIRI treatment regimen significantly improves overall survival (23.5 months vs. 20.0 months) and progression-free survival (9.9 months vs. 8.4 months).
The study confirmed that KRAS mutation status is a crucial predictive biomarker for the effectiveness of cetuximab, with 37% of tumors showing mutations, while BRAF mutations indicate a poorer prognosis.

In a study of 8 patients with recurrent/advanced colorectal cancer, 6 patients showed a positive response to cetuximab, a targeted therapy that binds to epidermal growth factor receptors (EGFR), indicating its efficacy even in later lines of treatment.
Patients receiving cetuximab in combination with CPT-11 had significantly better progression-free survival (7.3 months) and time to treatment failure (9.3 months) compared to those on cetuximab monotherapy (3.0 months and 4.5 months, respectively), highlighting the potential benefits of combination therapy.
