  • A Randomized, Double-blind, Placebo-controlled, Multinational, Phase 3 Study of the Efficacy and Safety of Inhaled Treprostinil in Subjects With Progressive Pulmonary Fibrosis (TETON-PPF) Rochester, Minn.

    The purpose of this study is to evaluate the safety and effectiveness of inhaled treprostinil in subjects with progressive pulmonary fibrosis (PPF) over a 52-week period.

  • Advancing Prevention of Pulmonary Fibrosis - A Cohort Study of Preclinical Pulmonary Fibrosis (APPLe) Rochester, Minn.

    The purpose of this study is to learn more about pulmonary fibrosis and how it develops to determine if the disease can be detected early, before the lung is permanently scarred. This study will enroll participants who are not currently diagnosed with pulmonary fibrosis, but who have family members with pulmonary fibrosis. Because there is an increased risk within affected families, this cohort will allow us to learn how pulmonary fibrosis develops, and how the lungs change over time.

  • An Open-label Extension Study of Inhaled Treprostinil in Subjects with Fibrotic Lung Disease (TETON-OLE) Rochester, Minn., Jacksonville, Fla.

    The purpose of this study is to evaluate the long-term safety and tolerability of inhaled treprostinil in subjects with fibrotic interstitial lung disease

  • Home-based Pulmonary Rehabilitation and Health Coaching in Fibrotic Interstitial Lung Disease Rochester, Minn.

    The purpose of this study is to assess the effect-size of a novel combined home-based telemonitored pulmonary rehabilitation and telephonic health coaching program on two co-primary endpoints: 1) patient-reported quality of life as assessed by the Chronic Respiratory Questionnaire (CRQ) and 2) physical activity (PA) as measured by steps per day.

  • Psychological Well-Being and Physical Activity in Patients with Fibrotic Interstitial Lung Disease: A Prospective Observational Cohort Study Rochester, Minn.

    This is a prospective observational cohort study assessing baseline and short-term changes in patient-reported outcomes and physical activity in patients with fibrotic interstitial lung disease (f-ILD). Primary endpoints will be the prevalence and extent of anxiety and depression at baseline and over time (6 months) with focused exploration of predictive and modifying covariables, and extent of physical activity at baseline and over time (6 months) and its impact on self-reported quality of life. All patients with f-ILD seen at Mayo Clinic Rochester will be enrolled by telephonic or in-person screening, and formally consented before enrollment. Measurements of symptom burden, psychologic and emotional health, and respiratory-related quality of life will be assessed with 9 standardized questionnaires, provided to participants electronically through an crypted REDCap link. Physical activity will be measured using the Actigraph GT3X-BT, a standardized research activity monitor worn on the wrist continuously for seven days. Mean steps per day and mean minutes of sedentary and moderate activity time will be serve as quantifiable physical activity endpoints. Baseline demographics, f-ILD disease subtype and duration, pulmonary function testing, radiologic findings, medical comorbidities, and social determinants of health will be obtained and followed over the 6 month period, in conjunction with repeated questionnaire and physical activity measures at enrollment, 3, and 6 months. Statistical analysis will involve descriptors of symptom burden, emotional and psychological wellbeing, and health-related quality at baseline and over time, as stratified by a prior subgroups or covariables. Particular focus will be on the extent and severity of anxiety and depression and any correlating or modifying variables, as assessed by multivariable logistic regression or predictive modeling with elastic net. Similar descriptors of physical activity extent and change over time correlating with baseline or changes in clinical, demographic, or patient-reported outcomes will also be pursued. For modeling and covariable adjustment, 250-300 participants will be enrolled to allow adjustment for up 10 variables for each outcome.
