About this study

Official title: Anderson-Fabry Disease Fitness Improvement Training: A-FAD-FIT

This study will evaluate physical function, cardiorespiratory fitness, muscle strength, and quality of life in patients with Fabry disease and assess the effects of a 12-week physiotherapy-led exercise programme. Participants will be non-randomly assigned to an exercise intervention group or a control group receiving no study-specific exercise intervention. The intervention group will be assessed at baseline, immediately after the 12-week intervention, and 12 months after baseline. The control group will be assessed at baseline and 12 months after baseline.

Read the detailed description

Fabry disease is a rare X-linked lysosomal storage disorder associated with multisystem involvement, reduced exercise tolerance, fatigue, pain, and impaired quality of life. Evidence regarding structured physiotherapy and exercise interventions in this population remains limited.

The aim of this study is to evaluate functional and cardiorespiratory capacity in patients with Fabry disease and to investigate the effects of a 12-week physiotherapy-led exercise programme. Participants will be non-randomly assigned to either an exercise intervention group or a control group receiving no study-specific exercise intervention. Group assignment will primarily reflect participants' willingness to participate in the exercise programme and logistical feasibility, particularly the ability to attend regular supervised exercise sessions.

Participants in the intervention group will complete a 12-week physiotherapy-led programme consisting of one supervised exercise session per week and two home-based exercise sessions per week. Supervised sessions include a brief aerobic warm-up followed by strengthening exercises using body weight and resistance bands. The programme also includes a progressive increase in daily ambulatory physical activity, monitored primarily by daily step count. Participants in the intervention group will be assessed at baseline, immediately after the 12-week intervention, and 12 months after baseline.

Participants in the control group will receive no study-specific exercise intervention and will be assessed at baseline and 12 months after baseline. The study will evaluate short-term changes following the exercise intervention as well as longer-term changes in the main study outcomes.

Questions about this trial

What is this clinical trial studying?

A study testing Physiotherapy exercise programe in people with Fabry Disease, run by General University Hospital, Prague at 1 site in Czechia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 21 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Czechia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jan Vávra, Masters (+420601200272, Jan.Vavra2@vfn.cz), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in peak oxygen uptake (VO2peak) after 12 weeks (time frame: Baseline and 12 weeks after baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Sep 2026.
