Oxford BioMedicahas said that results from a Phase I/II clinical trial of MVA-5T4 immunotherapy (TroVax) and low dose cyclophosphamide (CPM) in patients with advanced colorectal cancer (TaCTiCC) were positive with good responses of anti-5T4.
The company said that the study findings demonstrated that significant anti-5T4 immune responses were generated at treatment day 43. Secondary analysis revealed that both CPM and TroVax independently induced highly beneficial anti-tumour immune responses, resulting in significant survival of end stage colorectal cancer patients, without any major toxicity. This was the first randomised study to show a benefit of immunotherapy in advanced colorectal cancer patients.
Commenting on the results, John Dawson, Chief Executive Officer of Oxford BioMedica, said: “The presentation by the Clinical Investigators of the Phase I/II TaCTiCC study at the ASCO-SITC Clinical Immuno-Oncology symposium showed the potential benefit that Oxford BioMedica’s immunotherapy (TroVax) treatment could give to patients with advanced colorectal cancer.”
