About

The Prostate 8-II study is a randomized controlled trial of testing different combinations of educational and supportive tools related to diet and exercise to evaluate biological, clinical, and quality of life outcomes in men choosing radical prostatectomy as treatment for prostate cancer.

Full description

This is a PI initiated, randomized controlled trial of four exercise and diet interventions among men opting for radical prostatectomy for prostate cancer.

The Prostate 8-II study enrolls men up to 8 weeks prior to surgery and participants remain on study for 24 cycles after surgery (1 cycle=28 days). After obtaining written informed consent, enrolled subjects will be scheduled for the baseline assessments. All participants will receive Group A educational materials and tools, but these will be distributed at different times based on group assignment. The other 3 groups will receive different combinations of exercise (Group B), diet (Group C) and exercise and diet (Group D) tools. Men in all arms will be asked to complete questionnaires at baseline, pre-surgery, and at cycles 6,12, & 24 post-surgery, and complete blood and urine collection, diet recall, and accelerometer measurement at select time points. Specimens from biopsy and radical prostatectomy will be reviewed by the investigators' collaborator, GenomeDx, for RNA characterization and assessment of the genomic risk scores. Participants will be followed for 30 days after completion of the 2-year 24-cycle intervention period or removal from the study, or until death, whichever occurs first for any treatment-related adverse events. Following the completion of the intervention, participant's treatment and disease status will be collected on a yearly basis, for 3 more years.

204 participants in 4 patient groups

Arm A: Reference Group
Active Comparator group
Description:
Arm A will receive print educational materials about the benefits of exercise and diet for men with prostate cancer, with recommendations geared at men living with prostate cancer, mailed around the date of surgery. They also receive a 10-week text messaging program focused on recovery after radical prostatectomy surgery.
Treatment:
Behavioral: Exercise and Diet
Arm B (Arm A + Exercise)
Experimental group
Description:
Arm B receives the following: Arm A material plus access to an online portal with additional educational materials to help improve exercise habits and various tools, such as the ability to track exercise; additional educational print materials on exercise; additional text messages over 2 years that supports healthy exercise habits; and a 1-hour phone session at the start of the study followed by eight 30-minute quarterly phone sessions with an exercise coach over 2 years.
Treatment:
Behavioral: Exercise and Diet
Arm C (Arm A + Diet)
Experimental group
Description:
Arm C receives the following: Arm A material plus access to an online portal with additional educational materials to help improve diet habits and various tools, such as the ability to track diet; additional educational print materials on diet; additional text messages over 2 years that supports healthy diet habits; and a 1-hour phone session at the start of the study followed by eight 30-minute quarterly phone sessions with a diet coach over 2 years.
