Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.

What is this trial?

This study is testing whether your body position during BCG treatment — a standard therapy for non-muscle-invasive bladder cancer — makes a difference in how well it works. You'll receive your regular treatment three times, but each time you'll be asked to stay in a different position (no restrictions the first time, lying down the second time, and sitting the third time) to see if position affects how long the medicine stays in your bladder.

Doctors want to know if simple changes like body position can help this treatment work better for bladder cancer patients. There's a theory that keeping the medicine in contact with the bladder for longer might improve outcomes, and position might help with that.

Do you qualify?

You likely qualify if…

you have been diagnosed with intermediate or high-risk non-muscle-invasive bladder cancer and are starting BCG treatment for the first time
you are able to lie down flat for up to two hours at a time
you are able to sit upright for up to two hours at a time
you are willing to wear a fitness tracker (like a Fitbit) during the study
you are able to do a video or phone visit with the research team

You likely don't qualify if…

you have had BCG treatment within the past year
you have had significant urinary incontinence problems that make it hard to hold urine
you are unable to retain the medication in your bladder
you are unwilling to wear a fitness tracker during the study

What participation looks like

You'll come to the clinic once a week for three weeks to receive your standard treatment. The first week, you'll get the treatment and then go home with no activity restrictions. The second week, you'll stay lying down for as long as you can (up to 2 hours) before going home. The third week, you'll stay sitting upright for as long as you can (up to 2 hours) before going home. Throughout the study, you'll wear a fitness tracker to monitor your activity and vital signs, and you may have remote check-ins with the research team by phone or video.
