We continue to build significant capabilities in our infrastructure and partnering efforts to further drive momentum. In addition, further pre-clinical studies, conducted under the strategic research collaborations within our CARMA programs, are demonstrating the platform's potential for safety, anti-tumour activity and overall survival benefits. With consistently increasing visibility of revenues, we are trading in line with our expectations for the full year.
