Body position and bladder hold time during BCG treatment for non-muscle invasive bladder cancer

Official title: An Assessment of Patient Position and Intravesical BCG Dwell Time

Run by Ohio State University Comprehensive Cancer Center · NCT07474519 · Data updated 2026-11-12

This project will test whether lying down or sitting during BCG treatment changes how long the medicine stays in the bladder for people with intermediate- or high-risk non-muscle invasive bladder cancer.

Is this trial a fit for you?

Likely a good fit

People with intermediate- or high-risk non-muscle invasive bladder cancer who have not started induction BCG, can remain supine and sitting for up to two hours, and are willing to wear a fitness tracker are ideal candidates.

Probably not a fit

Patients who cannot retain BCG, have significant urinary incontinence, received intravesical BCG within the past year, or are unwilling/unable to wear the fitness tracker or attend the study center are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase IV study gives participants three weekly standard-of-care intravesical BCG treatments with different post-treatment positions: no activity restriction, lying down, and sitting, each held for up to two hours. Investigators measure BCG dwell time and use a Fitbit accelerometer to capture patient activity and vitals during a 24-hour baseline, treatment, and two hours post-treatment. The study enrolls patients with intermediate- or high-risk NMIBC who have not yet started induction BCG and compares dwell time across the three position conditions. The protocol also tests the feasibility of remote wearable monitoring to document mobility and retention during routine clinic-based BCG.

Why it matters

Potential benefit: If successful, the findings could lead to simple, low-cost position recommendations that increase BCG dwell time and potentially improve treatment effectiveness without adding medications.

How similar studies have gone: Prior research links longer BCG dwell time to better outcomes, but deliberately changing patient position to alter dwell time and using wearables for monitoring is largely novel and unproven.
