Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: All consecutive adult patients seen at the Mayo Clinic in Florida with a confirmed diagnosis of systemic sclerosis (SSc) will be eligible.

Who may be able to join

  • Adult patients ≥ 18 years old.
  • Fulfilling the American College of Rheumatology criteria for SSc.
  • For ILD subgroup (n=6):
  • An upright chest-roentgenogram (chest x-ray) is abnormal and compatible with an interstitial lung disease.
  • HRCT of the chest confirms the presence of bilateral reticular, ground glass, and/or honeycomb abnormalities that is otherwise unexplained by an alternative process
  • The HRCT fibrosis score must be ≥ 7.

  • The total lung capacity (TLC, measured by body plethysmography) and/or the diffusing capacity of the lung for carbon monoxide (DLCO) is below the predicted normal.
  • The forced vital capacity (FVC) is reduced below the predicted normal.
  • The patient is symptomatic (i.e. dyspnea and/or a chronic cough) for more than 8 weeks that is otherwise unexplained by an alternative mechanism.
  • For No ILD subgroup (n=6):
  • No radiographic evidence of ILD on plain chest x-ray.
  • The HRCT fibrosis score, when performed) must be < 7
  • The TLC and FVC are within their predicted normal.
  • The DLCO is within the predicted normal, except when reduced in isolation by pulmonary hypertension.

Who cannot join

  • Active smoking within the 6 months.
  • Pneumonia or bronchitis in past 4 weeks.
  • Active acute illness such as uncontrolled heart failure, infection, or asthma.
  • Use of more than 3 liters per minute (LPM) of oxygen by nasal cannula at rest.
  • Coordinator, investigator, or clinician concerns on the patient's compliance, safety, or in ability to complete study requirements.
  • Morbid condition not expected to live more than 1 year.
Show all 10Show fewer
  • Alternative cause or diagnosis for the patient's ILD besides SSc.
  • Pregnancy.
  • Obstructive lung disease with an FEV1 (forced expiratory volume in 1 second) to FVC ratio less than 0.7, nor radiographic evidence of emphysema on CT.
  • Planned therapeutic procedures involving the esophagus (e.g. dilation, surgery) prior to completion of study tests

Questions about this trial

What is this clinical trial studying?

An observational study of Scleroderma Lung, run by Mayo Clinic 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 14 inclusion and 10 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 8 Jan 2016. 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?

Airway pepsin concentration (time frame: cross-sectional). 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 8 Jan 2016.
