Evaluation of safety of Allogeneic Colon Cancer Cell Vaccinets


ABSTRACT: Intervention 1: Intervention group: Patients with colorectal cancer, stage 4 which receive chemotherapy and vaccine. The allogene vaccine (including three colon cancer cell lines) will be injected in two periods. The first period consists of three consecutive doses: the first dose will be injected one week after diagnosis /surgery, the following two doses will be injected with a week interval. One week after the third injection, chemotherapy will begin. After the first period, chemotherapy begins and continues for six months. The second period of the vaccine starts one month after chemotherapy and includes three consecutive vaccine doses with a distance of one week. Chemotherapy begins and continues two weeks after the sixth injection. 300 million tumor cells (108 cells from each cancer cell line) with 1 million BCG organisms are injected intradermally in the first and second injections. The third, fourth, fifth, and sixth injections contain 300 million irradiated tumor cells. Intervention 2: Control group: Patients with colorectal cancer, stage 4 which receive Chemotherapy treatment 5 weeks after diagnosis /surgery. Primary outcome(s): Measuring the levels of CA19-9. Timepoint: 6 months after the last vaccination. Method of measurement: via Elisa method.;Measuring the levels of CEA. Timepoint: 6 months after the last vaccination. Method of measurement: via Elisa method.;Measuring the levels of alanine aminotransferase. Timepoint: 6 months after the last vaccination. Method of measurement: via Elisa method.;Measuring the levels of aspartate aminotransferase. Timepoint: 6 months after the last vaccination. Method of measurement: via Elisa method.;Measuring the levels of alkaline phosphatase. Timepoint: 6 months after the last vaccination. Method of measurement: via Elisa method.;Measuring the levels of glutamyl tarnspeptidase. Timepoint: 6 months after the last vaccination. Method of measurement: via Elisa method.;Investigation of tumor formation. Timepoint: 6 months after the last vaccination. Method of measurement: via colonoscopy. Study Design: Randomization: Not randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment.
