Bladder Cancer and exeRcise Training During intraVesical thErapy

Study Overview
=================
Brief Summary
-----------------
Bladder cancer is the fifth most common cancer in Canada and has the eighth highest cancer mortality rate. The treatment for the most frequent type of bladder cancer is surgically removing the tumour followed by six weeks of medication placed within the bladder. There are physical and psychosocial challenges from bladder cancer and its treatment that may affect how patients feel and function, and consequently their quality of life. Moreover, bladder cancer patients are at a high risk of their bladder cancer coming back and getting worse. Exercise is a low-cost intervention that may lower the chances of bladder cancer coming back or getting worse, manage side effects related to treatment, help patients feel better, and improve quality of life. To date, however, no study has examined if it is safe or even possible for bladder cancer patients to exercise when they are receiving drugs placed into their bladder. The Bladder cancer and exeRcise trAining during intraVesical thErapy (BRAVE) Trial will be the first study to test the safety, feasibility, and efficacy of exercise in bladder cancer patients during this drug therapy. The investigators will ask some patients to do a supervised exercise program during their drug treatment while other patients will be asked not to exercise. The investigators will compare the 2 groups on how they fare with their bladder cancer treatment. This study will provide information on whether exercise may help patients feel better, function better, and possibly even lower their chances of the disease coming back or getting worse.

Design Details

Primary Purpose: Other
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Exercise Group<br>The exercise intervention will consist of 36 high-volume high-intensity interval sessions over a 12-week period. The exercise frequency will be three times per week during the 6 weeks of intravesical therapy and the 6 weeks of recovery (total 12 weeks) prior to a surveillance cystoscopy. | Other: High-Intensity Interval Training<br>* The intervention will be performed on a treadmill and will include a warm-up and cool-down at 50-60% and 40% of the VO2peak respectively, for up to five minutes. The HIIT protocol will be 4x4, which consists of four bouts of four minutes at a workload corresponding to vigorous intensity (75-95% of the baseline and 6-week VO2peak) alternating with three minutes of recovery intervals at 40% of the VO2peak. The exercise session will last 35 minutes and include 16 minutes of high intensity exercise.<br>|
| No Intervention: Usual Care:<br>Patients randomized to the control group will be asked not to initiate any exercise program or to increase their exercise level from baseline during the 12-week study. After the post-intervention assessments and 3-month cystoscopy, patients in the control group will be offered a 4-week supervised exercise program at the Behavioural Medicine Fitness Centre, University of Alberta. | |

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes of Peak Oxygen Consumption (VO2peak) | VO2 peak will be directly measured by the modified Bruce treadmill protocol exercise test, using a metabolic measurement system system (Parvo Medics TrueOne® 2400; Sandy, UT, USA).VO2peak will be defined as the highest oxygen-uptake value recorded during the test and will be expressed as relative to body mass (i.e., ml O2·kg-1·min-1). | At baseline, after the intravesical therapy (6-week), and 3-month follow-up | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Lower body strength | 30-second chair stand Scores are compared with normative data based on sex and age, with normal defined as the middle 50% of the population. Those scoring above this range would be considered above average for their age and those below the range as below average | At baseline, after the intravesical therapy (6-week), and 3-month follow-up | 
| Upper body strength | Arm curl Scores are compared with normative data based on sex and age, with normal defined as the middle 50% of the population. Those scoring above this range would be considered above average for their age and those below the range as below average | At baseline, after the intravesical therapy (6-week), and 3-month follow-up | 
| Lower body Flexibility | Chair sit-and-reach Scores are compared with normative data based on sex and age, with normal defined as the middle 50% of the population. Those scoring above this range would be considered above average for their age and those below the range as below average | At baseline, after the intravesical therapy (6-week), and 3-month follow-up |
