About this study

Official title: Prospective Validation of Cough, Dyspnea, and Quality of Life Questionnaires in Patients With Idiopathic Pulmonary Fibrosis (IPF)

The purpose of this study is to test cough, dyspnea (shortness of breath), and quality of life (QOL) questionnaires for their accuracy, sensitivity, and ability to reliably measure the severity of cough, breathlessness, and changes in cough and disease-related quality of life over time in Idiopathic Pulmonary Fibrosis (IPF) patients. These questionnaires have been used in other types of disease, but have not all been tested and validated in patients with cough due to IPF. Our hypothesis is that worsening of cough, dyspnea, and cough-related QOL questionnaire scores will correlate with physiologic markers of IPF severity and worsening of disease. Written, valid questionnaires measuring cough, dyspnea, and QOL are important to assess the benefit of investigational drugs under development to treat patients with IPF.

Read the detailed description

This study in patients with IPF will determine the validity, responsiveness, and reliability of two cough measures (the Leicester Cough Questionnaire (LCQ), as well as Visual Analogue Scales (VASs) for cough severity and distress; one dyspnea measure (the Baseline and Transition Dyspnea Index (BDI/TDI); and two health-related quality of life (HRQL) measures (the obstructive lung disease-specific Saint George's Respiratory Questionnaire (SGRQ) and the IPF-specific 'A Tool to Assess QOL in IPF' (ATAQ-IPF). Both the SGRQ and ATAQ include cough questions. Study participants will complete all questionnaires at baseline, 6, 12, and 18 months at the time of their usual clinic visits. Physiologic data will be collected at the same time of these visits including pulmonary function testing, exercise oxygen saturation, and changes in medications and health status. Changes in cough, dyspnea and QOL scores will be correlated with concurrent changes in physiologic markers of IPF severity. If a study participant has an acute worsening of their IPF, or undergoes lung transplantation, study questionnaires may be given at these additional timepoints when possible.

What participants receive

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

Study groups in NCT01874223
Study groupRoleWhat they receive
IPF-diagnosed patientsA group of up to 40 patients with a diagnosis of mild to severe IPF per American Thoracic Society (ATS) guidelines, either with no cough at baseline to severe cough at baseline, will be followed for at least a one-time assessment and every six months for up to 18 months to establish validity, responsiveness, and reliability of cough, dyspnea, and QOL instruments in patients with IPF.

What is being measured

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

  1. Correlation of LCQ scores with physiologic markers of IPF severity

    Change scores for the LCQ cough-related quality of life instrument will be correlated with changes in pulmonary function tests

    Measured: Baseline, 6, 12 and 18 months

Questions about this trial

What is this clinical trial studying?

An observational study of Interstitial Lung Disease and Idiopathic Pulmonary Fibrosis, 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 5 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 29 Aug 2022. 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?

Correlation of LCQ scores with physiologic markers of IPF severity (time frame: Baseline, 6, 12 and 18 months). 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 29 Aug 2022.
