Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single-center pilot randomized controlled trial among 68 physically "inactive" older men with lower urinary tract symptoms (LUTS) attributed to benign prostatic hyperplasia (LUTS/BPH) assessing a 12-week remote exercise intervention versus health education control.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will provide valuable insights into the feasibility of an individualized, remotely-monitored, and home-based exercise intervention as well as the effect of this intervention on lower urinary tract symptom (LUTS) severity and mechanistic measures (physical function, lower urinary tract function, frailty-related mechanistic biomarkers) in a diverse group of older men with LUTS attributed to benign prostatic hyperplasia (BPH). The potential public health benefit to society in this study could be large, as the investigators are targeting a common condition in older men (one in three older men develop LUTS in their lifetime).

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Single-center 2-arm pilot randomized control trial (RCT) of a 12-week remote exercise intervention and a health education control among 68 physically inactive older men with LUTS/BPH.

Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Investigators Outcome Assessors

This will be a 2-arm, partially-blinded, attention-controlled RCT. The randomization scheme will be computer-generated by the study statistician without participant contact. Participants will be randomized 1:1 in randomly permuted block sizes (2 or 4) to the exercise intervention or health education control arm stratified by recruitment site and any BPH medication use (yes/no). The randomization scheme is uploaded to University of California San Francisco (UCSF) REDCap and the study coordinator will randomize participants in UCSF REDCap. Assessors (for urinary and physical function testing), data analysts, and investigators will remain blinded to participants' randomization arm.

Primary outcomes will be collected using self-administered questionnaires without risk of unblinding. Intervention status and any variables related to intervention status will be recorded and stored in a separate database by unblinded Clinical Research Coordinator (CRC).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control Arm

Participants in this study arm will receive a remote health education program which consists of twice-monthly "Successful Aging" newsletters and phone calls to reinforce and discuss topics in each newsletter.

Group Type ACTIVE_COMPARATOR

Calls and Newsletter

Intervention Type OTHER

A 12-week remote health education program developed by the study team to provide a control for the exercise intervention. Participants in this arm will receive a summary of the American College of Sports Medicine guidelines (self-directed and time-based), a twice-monthly "Successful Aging" newsletter with suggestions for health diet, stress reduction, and social engagement, and twice-monthly phone calls to reinforce and discuss topics in the newsletter and to review adverse events and change in medications.

Exercise Arm

Participants in this study arm will receive an individualized 12-week exercise intervention plus a remote health education program.

Group Type EXPERIMENTAL

Exercise

Intervention Type BEHAVIORAL

An individualized 12-week exercise intervention that will follow American College of Sports Medicine guidelines to ensure a gradual safe increase in frequency and intensity. The exercise goals for participants in the intervention arm are to increase minutes/week of aerobic exercise, build strength and muscle mass, and improve flexibility, core strength, and balance progressively over the course of 12 weeks. The participants are prescribed 3 sessions of aerobic exercise lasting 45-75 minutes each, including warm up and cool down; 2 resistance training sessions per week, and at least 3 flexibility and balance sessions per week.

Intervention arm receives the following: Control arm "Successful Aging" newsletter plus additional educational materials related to exercise, heart rate monitor and resistance bands, and two 90-minute sessions and ten 30-minute phone sessions over 12 weeks with an exercise coach (the first two sessions include a resistance training session).

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age 60 years or older.
2. Male sex at birth.
3. Moderate-to-severe LUTS over the past month (defined as International Prostate Symptom Score \[IPSS\] \>=12).
