The purpose of this study is to learn more about the effectiveness and safety of the investigational drug called fenretinide (LAU-7b). The FDA has approved the testing of fenretinide in this study. Researchers hope that treatment with fenretinide will preserve lung function by reducing the persistent inflammation in the lung and to improve its capacity to defend against bacteria such as Pseudomonas aeruginosa. The drug will be administered by capsules. Your participation in this study will last approximately 7 months and includes 8 study visits to the study center (which will last approximately 2-5 hours) and 6 telephone calls. The phone calls are expected to last 10-15 minutes and depend on the amount of information you report.
The goal of this cohort and biorepository is to collect data and blood specimens on individuals with Nontuberculous Mycobacteria (NTM), pulmonary disease, and healthy adults to better understand the illness and ultimately improve the care and survival of those with these conditions.
The purpose of this study is to learn more about the effectiveness and safety of VX-561 used in patients with cystic fibrosis. Patients who have cystic fibrosis and are currently taking a stable dose of ivacaftor (IVA) are invited to take part in this research study. VX-561 is a form of IVA, an approved medication for some types of CF, that lasts longer in the body, allowing the medicine to be taken once a day instead of twice a day. Participation could last for approximately 20 weeks. There will be approximately 88 people participating in this study.
