CALIBER
Phase II randomised feasibility study of chemoresection and surgical management in low risk, non-muscle-invasive bladder cancer.
Disease site: Bladder cancer, urological cancers
Treatment modality: Intravesical chemotherapy, surgery
Status: Closed
Trial details
CALIBER is randomised, multicentre, phase II feasibility study investigating whether chemotherapy inside the bladder (chemoresection) could be a treatment option for people with recurrent low risk, non-muscle-invasive bladder cancer.
174 patients will be recruited from approximately 25 UK sites over 3 years. 116 patients will receive four once-weekly intravesical instillations of 40mg mitomycin C (chemoresection group) and 58 patients receiving the standard surgical management in use at their hospital for treatment of recurrence (surgical management control group).
The control group will provide prospective data about surgical management and outcomes and assess feasibility of recruitment to a randomised study. All participants will be followed up regularly during the first year after treatment and annually thereafter.
