Assessing a Digital Exercise Intervention for Health Outcomes and Engagement in Regular Exercise (ADHERE)

January 29, 2026 updated by: Royal Marsden NHS Foundation Trust

Assessing a Digital Exercise Intervention for Health Outcomes and Engagement in Regular Exercise (ADHERE): A Randomised Controlled Trial Comparing the Efficacy of a Digital Exercise Intervention With Virtual Supervised Group Exercise Sessions to Standard of Care on Exercise Adherence at Six Months in Patients With Prostate Cancer Undergoing Hormone Therapy.

Patients diagnosed with prostate cancer and receiving hormone therapy in conjunction with radiotherapy are likely to suffer from adverse effects caused by ADT treatment either short term or long term. The most common side effects include changes in body composition leading to increased visceral fat and reduced lean muscle mass, increased risk of cardiovascular events and fatigue, which overall lower quality of life.

There is strong evidence to support exercise interventions in minimising, and in some cases reversing many ADT -related toxicities, but exercise adherence remains a challenge for people living with prostate cancer, particularly due to logistical barriers to attendance such as cost and travel time, as well as insufficient motivation.

The aim of this single centre, phase III randomised controlled trial is to assess the efficacy of a new digital exercise programme with virtual supervised group exercise sessions in improving adherence to exercise guidelines.

The trial aims to recruit 160 participants with prostate cancer undergoing ADT, who will be allocated either the standard of care group or standard of care plus participation in the digital exercise intervention on a 1:1 ratio.

Adherence to physical activity will be measured using a wearable accelerometer, an exercise diary, self-reported questionnaires and clinic based assessments at 3 months, 6 months and 12 months post radiotherapy treatment. Recruitment will take place at the Royal Marsden NHS Foundation Trust, Chelsea.

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.

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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.
No Intervention: Standard of Care (SoC)
Participants will be sent a link to a webpage which provides information on physical activity and exercise guidelines, local and nationally available exercise, and contact details for the RMH physiotherapy department with the option to self-refer for further support.
Experimental: SoC + digital exercise intervention with virtual supervised group exercise sessions
Participants will receive standard of care and a digital exercise intervention.
Other: Participation in a digital exercise intervention with virtual supervised group exercise sessions

The intervention will involve an initial individual review with a clinical exercise physiologist (CEP) to complete a screening questionnaire, set goals and discuss details of physical activity and the exercise plan.

Participants will then attend weekly virtual supervised group exercise sessions and have access to pre-recorded exercise videos as well. Participants will receive motivational emails after each group session and have check-in phone calls with the CEP at week 4 and week 8.

Participants will also have the option to take part in the patient buddy scheme which includes three support phone calls from a fellow patient at The Royal Marsden NHS Foundation Trust. One phone call will be scheduled at the start of the exercise programme, one halfway through the programme, and one at the end of the programme.

Individual review appointments with the CEP will be scheduled at Week 13 and Week 26 to review progress and address any barriers to exercise adherence.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The primary endpoint is adherence to physical activity and exercise guidelines assessed using device-based activity data and self-reported physical activity and exercise data at six-months post-radiotherapy.
Time Frame: Measured at six months post radiotherapy

Activity data will be measured using the ActiGraph LEAP wearable activity monitor and an Exercise Diary.

To calculate physical activity and exercise adherence, we will compare the measured total volume of physical activity compared to the target volume of physical activity.
Measured at six months post radiotherapy
