RE-SEARCH study: A study to learn how and in which amount regorafenib is given in usual practice to patients in Spain: a study looking back at cases that have already happened when the study begins.

Trial purpose

Researchers are collecting more information to improve treatment of metastatic colorectal cancer (mCRC) with regorafenib.
Metastatic colorectal cancer (mCRC) is a cancer that starts in the large bowel and involves the rectum (the lowest part of the gut) and has spread to other parts of the body. Regorafenib is available to treat patients with mCRC that have previously been treated with, or are not considered candidates for, available therapies. It is an anti-cancer drug that blocks several proteins called enzymes which are involved in the growth of cancer. It is known that doctors may change the amount (the dose) of regorafenib they give, so that the patients better tolerate the treatment. Little information is however available on the doses of regorafenib given in Spain in usual practice.
In this study researchers want to learn how and in which amount regorafenib is usually given to patients with mCRC in Spain. They aim to identify the starting dose of regorafenib and to describe dosing patterns during the first two four-week treatment periods (cycles) according to usual clinical practice.
To answer these questions, the researchers will look back at cases that have already happened when the study begins. Medical history data from the day of diagnosis of the mCRC until the day prior to the inclusion in the study is collected from the medical records of adult patients with mCRC. All patients must have started their treatment with regorafenib since January 2017 and have taken regorafenib for at least 3 months.
The researchers will collect the information between around June 2021 until around November 2021. The final report is planned to be available in July 2022.
No investigational products will be administered in this study. Moreover, no additional visits or laboratory tests will be performed apart from the usual tests/treatments done in usual practice.
