The study will be a multi-center, double-blind, randomised, placebo-controlled 2-period cross-over study in subjects with chronic cough due to idiopathic pulmonary fibrosis (IPF).
Subjects will participate in one of two cohorts (Cohort 1 and Cohort 2). Cohort 1 will evaluate a 30 mg orvepitant dose and Cohort 2 the 10 mg dose. Within each cohort, subjects will be randomised to receive either orvepitant or placebo in the first treatment period (Treatment Period A) followed by the alternate treatment in Treatment Period B. There will be a wash-out period of 3 weeks between the two treatment periods. Subjects will be randomised 1:1 to each of the two treatment orders and 1:1 to each cohort. Subjects will enter a screening period of between 14 and 28 days to determine eligibility. Eligible subjects will be randomised at the Baseline visit and will participate in two identical 28 day treatment periods with the wash-out period between them. There will be a total of 8 visits including the Screening, Baseline and final Follow-up visits.

This is a Phase 3, randomized, double-blind, placebo-controlled, efficacy and safety study of subjects with IPF treated with inhaled treprostinil over a 52-week period. This study is investigating whether a drug called inhaled treprostinil (brand name Tyvaso®) works to help people with IPF improve their lung function tests. The purpose of this research study is to see how well inhaled treprostinil works in participants with IPF and to gather information on how safe it is. This study will look at changes in your breathing tests, also called lung function tests. About 396 people will participate in this study from about 100 medical centers. Your participation in this study is voluntary and will last approximately 58 weeks. This time includes a Screening Period that could last up to approximately 6 weeks plus a 52-week Treatment Period.

This is a multi-center, randomized, double-blind, placebo-controlled trial of 200 participants to receive N-acetyl cysteine (NAC) or placebo for a 24 month duration. The purpose of this study is to see if n-acetylcysteine (NAC) can help people with idiopathic pulmonary fibrosis (IPF) who have a specific gene type and to see if NAC is safe to take without causing too many side effects.

The purpose of this research registry is to better understand the natural history of Idiopathic Pulmonary Fibrosis and current practice patterns. The IPF-PRO registry will be used to collect data and biological samples that will support future research studies by identifying disease biomarkers for IPF. Through these studies, researchers hope to find new ways to detect, treat, and maybe prevent or cure health problems. Some of these studies may be about how genes affect health and disease, or how a person's genes affect their response to a treatment. Some of these studies may lead to new products, such as drugs or tests for diseases. We are asking you to let us collect and store some of your blood and health information so they might be used in these kinds of future studies.

If you are newly diagnosed with IPF and are eligible for participation in IPF-PRO, you will be asked to sign a consent form to become enrolled if you agree to be in this registry. At enrollment a member of MUSC research staff will collect information from you and about your medical history and medical care, as well as information about the types of health insurance (public or private) that you have. As part of your participation in this registry, you will be required to sign a medical release form giving permission for your medical records to be reviewed for the purposes of data collection for the registry. This is an observational registry which means you will not receive any investigational treatments or investigational drugs, and only minimally invasive procedures will be performed (blood draws) at scheduled clinic visits. In addition to the face to face visits for self-administered participant reported questionnaires and blood collection, at roughly 6-month intervals, sites will review the participant's medical records. Your disease management and treatment decisions will be determined by you and your health care professional. Subjects will be followed until the last enrolled subject has been followed for 3 years up to a maximum of 5 years.
