A trial looking at pembrolizumab for people with urothelial (urinary tract) cancer (Keynote 052)

This trial looked at pembrolizumab as a first treatment for cancer of the urinary tract. It was for people whose cancer couldn’t be removed with surgery, had come back after treatment or had spread elsewhere in the body.

The urinary tract includes the:

• centre of the kidney (renal pelvis)

• tube that takes urine from the kidney to the bladder (ureter)

• bladder

• tube that drains urine from the bladder and out of the body (urethra)

This trial was open for people to join between 2015 and 2016. The results were published in 2017.
