Trial Summary

What is the purpose of this trial?

The purpose of this study is to compare how long the participants are disease-free (progression-free survival) when treated with amivantamab and chemotherapy with 5-fluorouracil, leucovorin calcium (folinic acid) or levoleucovorin, oxaliplatin (mFOLFOX6) or 5-fluorouracil, leucovorin calcium (folinic acid) or levoleucovorin, and irinotecan hydrochloride (FOLFIRI) versus cetuximab and mFOLFOX6 or FOLFIRI in adult participants with Kirsten rat sarcoma viral oncogene homolog (KRAS)/ Neuroblastoma RAS viral oncogene homolog (NRAS) and v-Raf murine sarcoma viral oncogene homolog B1 (BRAF) wild type (WT) unresectable or metastatic left-sided colorectal cancer.

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 data supports the effectiveness of the drug Cetuximab when used with chemotherapy for colorectal cancer?

Cetuximab, when combined with chemotherapy, has shown promising results in treating metastatic colorectal cancer, improving progression-free survival and response rates. It has been effective in patients who have previously been treated with other chemotherapy drugs, restoring sensitivity to irinotecan and enhancing the overall treatment effect.12345

What safety information is available for Cetuximab in colorectal cancer treatment?

Cetuximab is generally well tolerated in patients with metastatic colorectal cancer, with common side effects including skin rash and low magnesium levels. Severe side effects are rare, but skin rash severity is linked to how well the treatment works.15678

What makes the drug combination of Amivantamab and Cetuximab with chemotherapy unique for colorectal cancer?

The combination of Amivantamab and Cetuximab with chemotherapy is unique because it involves two monoclonal antibodies targeting different pathways: Amivantamab targets the MET and EGFR pathways, while Cetuximab specifically targets the EGFR pathway. This dual targeting approach may offer a novel mechanism to enhance antitumor activity compared to standard treatments that typically focus on a single pathway.127910

Treatment Details

Interventions

  • Amivantamab
  • Cetuximab
Trial OverviewThe study compares two treatments: Amivantamab combined with chemotherapy (mFOLFOX6 or FOLFIRI) versus Cetuximab with the same chemo options. The goal is to see which treatment keeps the disease from worsening longer.

Findings from Research

In a study involving 65 patients with advanced colorectal cancer who had previously been treated with multiple therapies, the combination of cetuximab and irinotecan showed a response rate of 20% and a median overall survival of 10.4 months, confirming the efficacy of this treatment regimen.
The treatment was associated with low rates of severe toxicity, with only 8% experiencing grade 3 skin toxicity, indicating that cetuximab and irinotecan can be a safe option for heavily pretreated patients.
Cetuximab and irinotecan as third line therapy in patients with advanced colorectal cancer after failure of irinotecan, oxaliplatin and 5-fluorouracil.Pfeiffer, P., Nielsen, D., Yilmaz, M., et al.[2018]
Capecitabine, an oral chemotherapy drug, is at least as effective as traditional 5-FU plus leucovorin regimens for metastatic colorectal cancer (mCRC) and has a favorable safety profile.
Combining cetuximab with chemotherapy (like FOLFIRI) has been shown to improve progression-free survival and response rates in mCRC patients, with a recent phase III trial confirming these benefits over chemotherapy alone.
Cetuximab plus XELIRI or XELOX for first-line therapy of metastatic colorectal cancer.Moosmann, N., Heinemann, V.[2018]
Cetuximab, a monoclonal antibody targeting the EGFR, has shown effectiveness in treating metastatic colorectal cancer when combined with irinotecan, particularly in patients who have previously failed irinotecan-based therapies.
While cetuximab has demonstrated promising results in phase II trials for first-line therapy, further research is needed to confirm its efficacy in larger phase III trials and to optimize patient selection for treatment.
