COLOSSUS – Advancing a Precision Medicine Paradigm in Metastatic Colorectal Cancer: Systems Based Patient Stratification Solutions to create cost-effective, predictive diagnostic tools
What is the aim of the COLOSSUS study?
Colorectal cancer is the third most common cancer in Europe. In many cases treatment shows good results; however, there are patients who do not benefit from treatment or develop resistance to therapy.
COLOSSUS seeks to identify new biomarkers and classifiers for microsatellite stable RAS mutated colorectal cancer. Our aim is to develop new diagnostics and therapeutic options for patients bearing this type of cancer after they develop resistance to the current standard of care, and for whom there are no further treatment options currently available.
Our ultimate goal is to improve treatment outcomes for patients and deliver targeted and personalised treatment solutions.
Who can participate?
There are a number of criteria that patients must meet in order to participate in the study.
The key criteria for participating are listed below:
- Diagnosis of Stage IV microsatellite stable (MSS) RAS mutant colorectal cancer.
- Scheduled to receive standard of care chemotherapy with fluoropyrimidines and oxaliplatin +/- bevacizumab
- The ability to give signed informed consent prior to any study-specific procedures and willing and able to comply with the protocol.
- Age 18 years or over.
What do participants have to do?
Participants will be asked to:
- Contribute blood samples at two, possibly three different time points during the study.
- Provide access to the tissue which was taken during surgical treatment for colorectal cancer.
- Fill in two short questionnaires at two different time points to collect information about their well-being.
- Provide access to their clinical information to collect specific data for this study.
