This is a clinical trial to evaluate efficacy and safety of a drug activating the immune system MGN1703 in patients with advanced colorectal cancer, which achieved disease stabilization or improvement after initial chemotherapy. The patients will be assigned occasionally (like by tossing a coin) either to treatment with MGN1703 or with placebo, a preparation matching MGN1703, however, without the active substance.Patients with advanced colorectal carcinoma (AJCC Stage IV) with disease control after initial first-line therapyMedDRA version: 14.1Level: LLTClassification code 10010036Term: Colorectal carcinomaSystem Organ Class: 100000004864
