A Randomised phase II trial of Enhancement of efficacy of Atezolizumab by Radiotherapy in Metastatic urothelial carcinoma
Disease Site: Bladder cancer, urological cancers, urothelial cancer
Treatment Modality: Systemic therapy, radiotherapy
Status: Open to recruitment
RE-ARM is a phase II, multicentre trial in metastatic urothelial carcinoma in patients already being treated with atezolizumab. The trial will assess if the addition of radiotherapy will enhance the efficacy of atezolizumab.
102 patients will be recruited from UK sites. Patients will either be allocated to continue to receive atezolizumab alone or to receive radiotherapy of 20 Gy in 5 fractions during their first cycle of on trial atezolizumab. All patients will continue to receive atezolizumab for up to 2 years or until there is no longer a clinical benefit.
