What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new medicine called amivantamab on patients with advanced colorectal cancer. The medicine helps the immune system find and destroy cancer cells. Researchers want to see how well it works alone and with standard chemotherapy.

Will I have to stop taking my current medications?

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

Is the combination of Amivantamab and chemotherapy safe for treating colorectal cancer?

The safety of chemotherapy combinations like 5-fluorouracil (5-FU), leucovorin, irinotecan, and oxaliplatin has been studied in colorectal cancer, showing they are generally safe with manageable side effects. However, specific safety data for Amivantamab combined with these chemotherapies in colorectal cancer is not provided in the available research. ^{1 2 3 4 5}

What makes the drug Amivantamab + Chemotherapy unique for colorectal cancer?

This treatment combines Amivantamab, a novel drug targeting specific cancer cell pathways, with established chemotherapy agents like Fluorouracil, Irinotecan, Leucovorin, and Oxaliplatin, which are standard in colorectal cancer treatment. The inclusion of Amivantamab, which is not typically used for colorectal cancer, may offer a new approach by potentially enhancing the effectiveness of the chemotherapy regimen. ^{6 7 8 9 10}

What data supports the effectiveness of the drug combination Amivantamab + Chemotherapy for Colorectal Cancer?

Research shows that combinations of chemotherapy drugs like fluorouracil (5-FU), leucovorin, oxaliplatin, and irinotecan have improved survival rates in colorectal cancer patients. These combinations are standard treatments and have shown to be effective in both early and advanced stages of the disease. ^{3 7 9 11 12}

In a study involving 101 patients with metastatic colorectal cancer who had previously failed a 5-FU-based treatment, three different chemotherapy combinations showed promising tumor growth control, with overall response rates ranging from 11.4% to 21.2%.

All treatment regimens resulted in similar overall survival rates around 11 to 12 months, and while there was a notable incidence of grade 3-4 neutropenia (33-39% of patients), the safety profile was considered acceptable for these second-line therapies.
