This study is investigating the drug, called mosliciguat, for the treatment of PH-ILD. Participation in the study may last for about 4 ½ years, although the actual time of participation may be shorter or longer. Part 1 of the study will take about 6 months. Part 2 of the study could last up to about 4 years. During the study, participants will be required to make clinic visits in person and at times will need to meet with study staff over the phone/video. At some of the clinic visits, participants will have blood drawn and have procedures to test their lungs and heart function. Participants will be randomly assigned to get mosliciguat or placebo in Part 1. In Part 2, all participants will get mosliciguat. Approximately 120 people will participate in this study.

This is a randomized, double-blind, placebo-controlled clinical study to evaluate the safety and efficacy of 2 doses of AP01 versus placebo on top of standard of care in subjects with Progressive Pulmonary Fibrosis (PPF) over 52 weeks. Subjects will participate in the study for up to 58 weeks, inclusive of a Screening Period of up to 4 weeks, a 52-week Treatment Period, and a 2-week Follow-up Period that includes a Follow-up telephone call (TC) 2 weeks post final dose. Up to 300 eligible subjects will be randomized in a 2:1:2 ratio to 1 of 3 treatment arms: AP01 100 mg twice daily (BID), AP01 50 mg BID, or placebo BID (8 mL; two 4 mL blow-fill-seal [BFS] ampoules BID).

This is a Phase 2a, randomized, double-blind, multi-center, placebo-controlled, parallel-design, 2-arm study. This study will be conducted in approximately 20 centers globally, in subjects with IPF. Participation will last for about 18 weeks and include about 12 study clinic visits with the Study Doctor and/or study staff. This study will take place over approximately a year. The study will investigate a single dose level of GRI-0621 of 4.5mg compared with placebo, following once daily oral administration for 12 weeks. Approximately 36 subjects with IPF will be randomized in a 2:1 ratio for GRI-0621 4.5mg or Placebo. The study consists of a Screening Period, a Treatment Period and a Safety Follow-Up Period. The Screening Period will be conducted within 4 weeks prior to randomization, and is comprised of at least two separate in-clinic visits to assess eligibility.
Concurrently, a BAL Sub-Study will be conducted, for up to 12 eligible subjects (across various centers). The objective of the Sub-Study is to examine the role of NKT cells in fibrotic lung disease.

Study LTI-401 is an open-label, multicenter study which will evaluate the safety and tolerability of LIQ861, the study drug, in subjects who have World Health Organization (WHO) Group 1 & 3 Pulmonary Hypertension. The purpose of this research study is to evaluate the long-term safety and tolerability of LIQ861 in patients with WHO Group 3 Pulmonary Hypertension associated with interstitial lung disease (PH-ILD). The investigational form of Treprostinil in this study is called LIQ861, it is delivered to your lungs using a hand-held device called a dry powder inhaler (DPI). Dose levels may be adjusted by the Study Doctor between 26.5 micrograms to 318 micrograms based on your PH-ILD symptoms. The study will include approximately 60 subjects and participation will last 52 weeks.

This is a Phase 3, randomized, double-blind, placebo-controlled, multinational, efficacy and safety study of subjects with PPF (Progressive Pulmonary Fibrosis) 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 PPF improve their lung function tests. The purpose of this research study is to see how well inhaled treprostinil works in participants with PPF 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 698 people will participate in this study from about 150 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 Phase 3, multicenter, randomized, double-blind, placebo-controlled clinical study that will randomize participants with Progressive Pulmonary Fibrosis to study drug BMS-986278 60mg, 120mg, or Placebo, administered orally, twice a day. Participants are allowed to continue background therapy, such as antifibrotic and immunosuppressant therapies. This study will consist of two parts (Cohort 1 and 2). Cohort 1 will enroll approximately 60 participants with Progressive Pulmonary Fibrosis to evaluate the safety and tolerability of BMS-986278 in which participants will be randomized to receive 60 mg, 120mg, or placebo and this will last approximately 52 weeks. Cohort 2 is a registrational, double-blinded study which will investigate the efficacy, safety, and tolerability of BMS-986278 compared with placebo. Based on data from Cohort 1, the study will design 2 or 3 treatment arms for Cohort 2.

The IM027068 Phase 3, multicenter, randomized, double-blind, placebo-controlled clinical study will randomize participants with IPF (Idiopathic Pulmonary Fibrosis) to BMS-986278- 60 mg or 120 mg, or placebo PO BID (orally, twice a day). Participants are allowed to continue antifibrotic therapy for IPF with nintedanib or pirfenidone. The study will utilize a 2-cohort design. Cohort 1 will enroll approximately 60 participants with IPF to evaluate the safety and tolerability of BMS-986278 in which participants will be randomized to receive 60 mg, 120mg, or placebo and this will last approximately 52 weeks. Cohort 2 is a registrational, double-blinded study which will investigate the efficacy, safety, and tolerability of BMS-986278 compared with placebo. Based on data from Cohort 1, the study will design 2 or 3 treatment arms for Cohort 2.

This is a randomized, double-blind, dose-ranging, placebo-controlled study to see how effectively and how safely two different doses of bexotegrast (160 and 320 mg) can be taken every day for 52 weeks (about 12 months) by subjects with IPF (Idiopathic Pulmonary Fibrosis) who are taking or not taking background therapy (other drugs for IPF include nintedanib or pirfenidone). The study is designed to test the study drug in subjects who are taking or not taking background therapy and will include about 80 subjects who are not taking background therapy at study entry. Subjects who are not taking background therapy at study entry will be allowed to start it at any time during the study. The study will consist of an up to 28-day Screening Period, a 52-week Treatment Period, and a 14-day Safety Follow-up Period. Participants will undergo an end-of-study visit at the end of the Safety Follow-up Period.

This multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical
study is designed to evaluate the safety and tolerability of 3 dose levels of TTI-101 vs placebo in participants with idiopathic pulmonary fibrosis (IPF). a screening period of up to 28 days, 100 participants will be randomly assigned to receive 1 of 3 dose levels of TTI-101 (25 participants per dose level) or matching placebo (25 participants). Enrollment will be stratified by current use of nintedanib. The assigned study drug will be self-administered orally in tablet form twice daily (BID) with a glass of water after a meal. Once randomized, each participant will maintain their current standard of care supportive medications, including cough treatment, medications for symptom relief or quality of life improvements, oxygen therapy where indicated, respiratory physiotherapy, and treatment of comorbidities. Following randomization, all participants will enter the 12-week, double-blind treatment period.

The purpose of this study is to learn more about interstitial lung disease through collection of information and blood samples to be used in future research projects. Basic information and a blood sample will be collected in conjunction with clinical care for this study, approximately every 3 months.
