The Program will allow access to brensocatib for patients who have completed the INS1007-301 ASPEN Clinical Trial. Patients will receive brensocatib 10 mg orally once daily. Eligible, compliant patients may receive brensocatib in this program until the drug is commercially available or until Insmed terminates the program.

The study will be an open-label, randomized, parallel arm study that will include a
treatment arm and control arm. Participants will have clinic visits at screening, randomization (day 1) and weeks 4, 12, 18, and 24. After week 24, participants will have clinic visits at weeks 32, 40, and 48. Participants will also have a telehealth visit on day 2 and phone calls to assess adverse events (AEs), serious adverse events (SAEs), and review patient education will occur during weeks 5, 8, 36, and 44. The phone calls may be converted to telehealth visits or clinic visits and / or followed by clinic visits, if the study team deems it necessary. Pulmonary function testing, quality of life survey (St. George's Respiratory Questionnaire (SGRQ)), and blood draw will occur at each clinic visit.

Following the study Entry Visit, subjects will return at Week 4,
Week 12, and every 12 weeks thereafter. Study visits will continue
for up to 6 years or until the subject prematurely discontinues study
treatment due to an adverse event or other reason, inhaled treprostinil
becomes commercially available for IPF in the region in which the
study is conducted, or the study is discontinued by the Sponsor
(whichever is sooner). Subjects will also be contacted by telephone or
email at least weekly until Week 12 and monthly thereafter in
between study visits to discuss study drug titration, assess study drug
tolerability, monitor adverse event, document changes to concomitant
medications, and remind subjects to bring in all study drug and a
device to their next clinic visit.

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.
