The ISARIC4C investigators collaborated with Prof Carlo Palmieri and team to characterise the first 1,797 hospitalised patients with cancer and COVID-19. From here a new study was launched to assess the impact of COVID-19 on people with cancer: The Clinical Characterisation Protocol (CCP) CANCER-UK. The project will run over 12 months and will examine questions that are important for the care of patients with cancer. With almost 7,000 patients with both confirmed cancer and COVID-19 diagnoses already enrolled, it will be one of the largest and most detailed studies in the world. The study has received funding from UK Research and Innovation (UKRI) and the National Institute for Health Research (NIHR), with additional funding from The Clatterbridge Cancer Charity.
