February 20, 2019 updated by: University of California, San Francisco

A Randomized Clinical Trial of Web-based Lifestyle Tools and Resources Versus Usual Care Among Men With Prostate Cancer

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a PI-initiated, randomized, unblinded, clinical trial of a technology-based 3 month lifestyle intervention vs. usual care among men with low risk prostate cancer. We will recruit and consent 76 men with prostate cancer at UCSF. The subjects will be asked to complete questionnaires, 7 days accelerometer measurement, body measurements (weight, waist, hip, pulse, blood pressure) and collection of blood specimen at baseline and 3 months. Subjects will be randomized into two arms (Intervention Group and Control Group). The Intervention Group (N=38) will have access to the lifestyle website and an activity monitor (e.g., Fitbit), receive text messages, and be provided with individualized lifestyle recommendations. The Control Group (N=38) will have standard of care and be asked to continue with their usual lifestyle habits. They will receive access to the lifestyle website and be provided with individualized lifestyle recommendations at 3 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Group 1- Lifestyle Intervention
Men will receive a web-based, personalized lifestyle program. They will receive personalized prostate cancer-specific lifestyle recommendations on specific habits based on their eligibility survey responses. They will have access to the website composed of four topic areas (get active, eat well, stop smoking, and find support), receive a Fitbit and access to a Fitbit account and community group, and receive text messages and refrigerator magnet to reinforce behaviors. The website will be updated frequently with new tips and material and two weekly blogs will be maintained. Final content is reviewed by study investigators and patient advocates. Men will complete an intervention acceptability survey (acceptability of the website and intervention components) at 3 months.
Behavioral: Lifestyle intervention
Patients will have access to the lifestyle website and an activity monitor (e.g., Fitbit), receive texts, and be provided with individualized lifestyle recommendations.
No Intervention: Group 2 - Control
Men randomized to the control group will receive standard of care. They will receive access to the website and personalized lifestyle recommendations on the 8 healthy habits targeted in the study after the 3 month trial.

What is the study measuring?
