About this study

The aim of this study is to conduct survey-based assessments for the safety of air travel in patients with pulmonary Langerhans cell histiocytosis (PLCH). The study will enroll patients through the clinic network at Rare Lung Disease Consortium (RLDC) and through the Histiocytosis Association website. Patients will have access to the questionnaire via REDCap (an online data management system) and each patient will be provided with a link to complete the survey. The investigators plan on enrolling approximately 200 patients with PLCH for the purpose of this study. Secondary aims of this study include further characterization of the clinical aspects of disease and to establish a contact registry for these patients, in order to facilitate future studies.

Read the detailed description

The study will enroll participants through the clinic network at the Rare Lung Disease Consortium (RLDC) and through the Histiocytosis Association websites. Participants will have access to the questionnaire via REDCap (an online data management system) and each participant will be provided a link to complete the survey. In case of lack of internet access or inability to complete the online questionnaire, a paper survey will be mailed out with a pre-paid envelope to return the survey.

Primary Study Objective(s):

To define the risk of pneumothorax associated with air travel in patients with PLCH.

Secondary Study Objective(s):

To establish a contact registry for patients with PLCH to facilitate future trials To assess the rate of pneumothorax recurrence in patients with PLCH To assess the efficacy of pleurodesis in preventing recurrent pneumothoraces among patients with PLCH

What is being measured

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

  1. Number of Participants With PLCH Who Experienced Spontaneous Pneumothorax During or Within 24 Hours Following Air Travel

    The investigators will measure the number of pneumothoraces that occur either during air travel, or within 24 hours of air travel among patients with pulmonary Langerhans cell histiocytosis. The incidence of air travel related pneumothorax will be calculated by dividing the number of pneumothoraces to the total number of flights undertaken by the entire cohort.

    Measured: During air travel or within 24 hours following air travel

Secondary outcomes (2)
  1. Number of Patients With Pulmonary Langerhans Cell Histiocytosis Who Experienced a Spontaneous Pneumothorax

    The investigators will catalogue the number of spontaneous pneumothoraces experienced by patients with pulmonary Langerhans cell histiocytosis.

    Measured: 2 years and 6 months

  2. Number of Patients With Pulmonary Langerhans Cell Histiocytosis Who Experienced Recurrent Pneumothorax

    The investigators will measure the number of participants who experience a recurrent spontaneous pneumothorax.

    Measured: 2 years and 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Langerhans Cell Histiocytosis, run by University of Cincinnati 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 4 inclusion and 1 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 31 Jan 2024. 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?

Yes. Results are posted in the registry (first posted 31 Jan 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With PLCH Who Experienced Spontaneous Pneumothorax During or Within 24 Hours Following Air Travel (time frame: During air travel or within 24 hours following air travel). 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 NCT03052101, 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 31 Jan 2024.
