IMPROVE Intervention Trial


Brief description of study

A open label 1:1 randomized phase II exploratory study investigating adjuvant therapy in patients with molecular biologically detectable residual disease after primary resection for localized colorectal tumors.

Detailed Study Description

The main clinical hypothesis is that patients having undergone radical resection from CRC do not present with detectable tumor DNA in the plasma, whereas patients with detectable tumor DNA two weeks' post surgery have residual microscopic disease, and consequently a high risk of diseases recurrence which can be prevented with adjuvant chemotherapy.

The primary aim of the present study is to investigate - in a randomized trial - if use of standard adjuvant chemotherapy therapy improves the disease free survival in patients with molecular biological residual disease where adjuvant chemotherapy is not standard treatment .

Secondary aims include investigating molecular biological response to adjuvant chemotherapy in patients with post-operative ctDNA.
