Trial summary

Marfan patients are at risk of sudden death due to weakening of the wall of the large blood vessel leading from the heart (aorta). The wall of the aorta weakens and dilates which can rupture, leading to death, and sometimes during intense exercise. Read more about this study

About this study

Marfan patients are at risk of sudden death due to weakening of the wall of the large blood vessel leading from the heart (aorta). The wall of the aorta weakens and dilates which can rupture, leading to death, and sometimes during intense exercise.

There is some evidence in Marfan patients that a stiffer aorta increases risk for rupture.

For some time, clinical care has focused on what type of exercise these patients should avoid due to risk for aortic dissection. Little clinical emphasis has been placed on encouraging patients to engage in routine and safe exercise such as walking. Informed by this evidence, the investigators propose to collaboratively investigate whether regular exercise improves aortic health in adolescent Marfan patients.

Read the detailed description

Marfan syndrome is an inherited disorder of the connective tissue, which provides material and support for the skeleton, muscles, and blood vessels. Marfan patients are at risk of sudden death due to weakening of the wall of the large blood vessel leading from the heart (aorta). The wall of the aorta weakens and dilates which can rupture, leading to death, and sometimes during intense exercise.

Typically, the weakening process starts when elastin fibers in the aorta become fragmented. There is some evidence in Marfan patients that a stiffer aorta increases risk for rupture.

For some time, clinical care has focused on what type of exercise these patients should avoid due to risk for aortic dissection. Little clinical emphasis has been placed on encouraging patients to engage in routine and safe exercise such as walking. These young patients also frequently choose sedentary lifestyles, most likely due to limitations imposed by parents as well as adolescents' own perceptions of what is safe for them and their physical capabilities. Another complicating factor is that these patients often experience difficulty coping with their diagnosis. Informed by this evidence, the investigators propose to collaboratively investigate whether regular exercise improves aortic health and coping skills in adolescent Marfan patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ExerciseBehavioural

    Across studies in adolescents in general population, 60 minutes of recommended daily exercise level is achieved, on average, within a total volume of 10,000-11,700 steps. The investigators will assess baseline physical activity quantitatively by using an accelerometer worn on the wrist during waking hours over a 7-day period. Each participant will be given a Garmin device to place on their wrist that will track their steps. Then patients will be asked to complete 10,000 steps daily for 6 months (acclimation over a week), which will be encouraged by daily text messages or e-mail, and weekly phone calls by the intervention team in addition to a Garmin and Facebook peer group.

10,000 Steps/day for Pediatric Marfan PatientsExperimentalParticipants will be given a Garmin VivoFit and asked to take at least 10,000 steps per day. A study coordinator will reach out at least once per week to check in on progress made and help make weekly goals.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To determine if 6 months of regular physical activity improves aortic stiffness in MFS patients. exercise, a decrease in expressed biomarkers, and an increase in COPE scores of MFS patients.

    The investigators' primary outcome measure is aortic stiffness measured by arterial tonometry (pulse wave velocity).

    Measured: 6 months of intervention

Secondary outcomes (4)
  1. To determine if 6 months of regular physical activity improves aortic stiffness and the biomarker profile in MFS patients.

    The secondary outcomes include aortic stiffness at the aortic root at the level of the sinuses of Valsalva and ascending aorta.

    Measured: 6 months of intervention

  2. To determine if 6 months of regular physical activity improves aortic stiffness and the biomarker profile in MFS patients.

    Secondary outcomes will be expression levels of TGF-β, Ang-II, MMP-2 \& -9, ROS levels.

    Measured: 6 months of intervention

  3. To determine if 6 months of regular physical activity decreases aortic stiffness and rate of aortic root dilation in Marfan mice.

    Secondary outcomes will be expression levels of TGF-β, MMP-2, MMP-9, and ROS.

    Measured: 6 months of intervention

  4. To determine if 6 months of regular physical activity improves coping skills in Marfan patients.

    The outcome measure is the COPE inventory score.

    Measured: 6 months of intervention

Questions about this trial

What is this clinical trial studying?

A study testing Exercise in people with Marfan Syndrome, run by Stanford University at 1 site in United States.

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 3 inclusion and 2 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: finished, as of the sponsor's last update on 27 Jul 2020. 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 United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine if 6 months of regular physical activity improves aortic stiffness in MFS patients. exercise, a decrease in expressed biomarkers, and an increase in COPE scores of MFS patients. (time frame: 6 months of intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03567460, which also lists 1 linked publication.

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 27 Jul 2020.
