Improving treatment for colorectal cancer using a KRAS peptide vaccine

Optimization of an active mutant KRAS peptide vaccine in colorectal cancer

NIH-funded research Johns Hopkins University · NIH-11023637

This study is testing a new vaccine called mKRASvax that aims to help the immune system fight advanced colorectal cancer by targeting specific gene mutations, and it's looking for patients whose cancer hasn't responded to regular treatments to see if this can work better alongside other therapies.

What this research studies

This research focuses on developing a vaccine that targets specific mutations in the KRAS gene, which are common in colorectal cancer. The vaccine, called mKRASvax, combines six synthetic long peptides to stimulate the immune system, particularly T cells, to recognize and attack cancer cells with these mutations. The approach is being tested alongside existing immunotherapies, such as anti-PD-1 and anti-CTLA-4 antibodies, to enhance their effectiveness in patients with advanced colorectal cancer. Patients with certain types of colorectal cancer that have not responded to standard treatments may be eligible to participate in this innovative approach.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients with metastatic microsatellite stable colorectal cancer who have not responded to previous chemotherapy treatments.

Not a fit: Patients with colorectal cancer that does not involve KRAS mutations or those who are not advanced in their disease may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to more effective treatment options for patients with colorectal cancer, particularly those with KRAS mutations.

How similar studies have performed: Previous research has shown promising results with similar vaccine approaches in other cancers, indicating potential for success in this novel application.
