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.
The main purpose of this study is to see if important factors can be identified in each of the three categories (patient, catheter, and catheter management) that are linked to blood clotting complications. This is a multicenter, prospective observational study to evaluate risk factors associated with complications of peripherally inserted central catheter (PICCs) and midline catheters. Both adult and pediatric patients with CF who receive care at participating centers will be eligible for participation. This study can last for 2 weeks.
The purpose of this stuThe purpose of this study is to learn more about the safety and effectiveness of VX-445 used in combination with TEZ and VX-561 in patients with cystic fibrosis. Participation could last for approximately 100 weeks. This will include a treatment period that will last approximately 96 weeks, and a safety follow-up period that will last approximately 4 weeks after the last dose of Study Drug. Approximately 400 people will participate in this study.
The is a Phase 2, randomized, double-blind, placebo-controlled study that will be
conducted at multiple centers. The study population is comprised of adult subjects with Cystic Fibrosis, and who have been taking tezacaftor/ivacaftor for the treatment of the disease. The planned sample size is approximately 40 subjects. Participation in this study will last up to approximately 10 weeks and include a screening visit and 9 visits to the study center.
The purpose of this study is learn more about the effectiveness and safety of VX-445 used in combination with TEZ, IVA and VX-561 in patients with cystic fibrosis.
Participation could last for approximately 16 weeks. This will include a Screening Period that will last up to 4 weeks, a Run-in Period that will last up to 4 weeks, a Treatment Period that will last up to 4 weeks, and a Follow-up Period that may last up to 4 weeks after the last dose of Study Drug. Approximately 100 people will participate in this study.
In this study, PTI-808 will be given alone and in combination with two other experimental drugs, PTI-801 and PTI-428. PTI-428, PTI-801, and PTI-808 are considered cystic fibrosis transmembrane conductance regulator (CFTR) modulators being developed to treat the underlying mechanism of cystic fibrosis. PTI-428 is a CFTR amplifier that increases the amount of CFTR protein in the cell, PTI-801 is a CFTR corrector that improves the processing of CFTR protein in the cell, and PTI-808 is a CFTR potentiator to enhance the activity of CFTR at the cell surface. Individual modulators have been shown to have limited activity, and therefore it is predicted that a combination of modulators will be required to fully address the CFTR protein defects. The study will also obtain information on how the study drug moves into, through, and out of the body. The expected duration of this study is up to 57 days
This is a randomized, double-blind, multi-center study in pediatric
subjects age 3 months to less than 18 years with CF and newly
detected PA respiratory tract colonization/infection. The study
schedule will consist of a minimum of 13 visits: Screening, Day 1
(Baseline and Randomization), Day 29, Weeks 6, 8, 16, and at
12-week intervals thereafter through Week 112. Subjects may be
screened up to 14 days prior to the Baseline visit to determine
eligibility for participation in the study. Screening and Baseline may
occur on the same day for subjects.
This is a research study to find out if a drug called lenabasum can help people with Cystic Fibrosis (CF) and if it is safe to take without causing too many side effects. There are 9 planned study visits in the institution during this study.
This is an observational study which will collect sweat chloride values from approximately 1000 cystic fibrosis subjects who are currently on cystic fibrosis transmembrane conductance regulator (CFTR) modulators. This study will require one visit to an MUSC clinic which will last approximately 2 hours. Compensation is provided.
