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.

This is a multi-center early feasibility study evaluating the safety and tolerability of the 3P-100 device which creates and delivers iNO for the treatment of subjects with PH-ILD. All subjects will use the 3P-100 device and receive iNO via the 3P-100 device, aiming for ~4-4.5 hours of treatment. All subjects will remain on their prescribed Oxygen (O2). The study consists of an SV, an iNO treatment period at V1 (Day 0), and a Telephone Call at V1 + 1 Day for safety follow-up.

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.

This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, study to evaluate the efficacy, safety, and tolerability of 200 mg twice daily (BID) of BBT-877 in patients with IPF, with or without AF approved background therapies (pirfenidone or nintedanib). For both the placebo and BBT-877 groups, patients will be selected so that 40% to 60% of the patients in each group will be treated with pirfenidone or nintedanib in order to investigate if BBT-877 could be used as either monotherapy or add-on therapy to AFs, to further reduce the decline in lung function and/or improve symptoms as compared to those drugs alone. As a result, 60% to 40% of the patients will receive BBT-877 or placebo, alone.

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.
