Study information
Scientific title
A phase II randomised feasibility study of chemoresection or surgical management in low risk non muscle invasive bladder cancer
Acronym
CALIBER
Study hypothesis
Current hypothesis as of 10/04/2017:
To demonstrate that chemoresection has sufficient activity against NMIBC to warrant further investigation of its role as a potential alternative to surgical intervention for low risk NMIBC recurrence.
Previous hypothesis:
CALIBER aims to demonstrate that chemoresection will enable 60% of participants to avoid surgical intervention for low risk NMIBC recurrence, as assessed by response rate at 3 months.
