This is a research study to test a new investigational drug, PTI-801. An investigational drug is one that is not approved by the US FDA. In this study, PTI-801 will be compared to placebo (a capsule that looks like the investigational drug, but does not contain an active drug substance). Although PTI-801 has been given to normal healthy adults, this is the FIRST time that PTI-801 has been given to people with CF.
This study has two parts and will assess your hearing and the potential effects of antibiotic-induced ototoxicity. Ototoxicity is a potential effect of drugs used to treat your lung infections, and its effect on your ears (oto=ears), particularly structures in your inner ear that enable hearing and balance. Part One of the study will assess your inner ear function that may be associated with hearing loss and / or loss of balance in cystic fibrosis patients taking tobramycin. Part Two is looking to determine if SPI-1005, an investigational drug, influences hearing loss, due to mediations (tobramycin).
Cystic fibrosis is caused by changes in the genes of your DNA (Deoxyribonucleic Acid) encoding for the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein. These changes cause the CFTR to stop working as it should. GLPG2222 is being studied for treatment of cystic fibrosis. The study drug is designed to improve the expression and function of CFTR, which may improve some of the symptoms of cystic fibrosis.
The purpose of this study is to learn more about the safety and efficacy of the combination of tezacaftor/ivacaftor (TEZ/IVA) in subjects with CF who have previously discontinued Orkambi. Orkambi® is a combination of ivacaftor with another drug called lumacaftor. This study is being conducted to test whether combining ivacaftor with tezacaftor instead will improve symptoms of cystic fibrosis and cause fewer respiratory side effects.
This study is being done to evaluate an experimental treatment for people with Cystic Fibrosis who have a bacterial infection in their lungs. Subjects will be randomized (selected by chance) to either be treated with an investigational inhaled gaseous drug (in 99.5% nitrogen) that is mixed with room air or breathe 100% nitrogen that is mixed with room air. If you are randomized to the investigational treatment, we are asking you to breathe in a gas called ?nitric oxide?. Participation in the study will take about 43 days
Lamprene®/Clofazimine, is a product of the pharmaceutical company named Novartis Pharmaceuticals Corporation. Lamprene®/Clofazimine is approved by FDA (the U.S Food and Drug Administration) for the treatment of leprosy. It is being tested in non-Novartis clinical studies for drug resistant tuberculosis and non-tuberculous mycobacteria (NTM).
If you have been diagnosed with NTM, then your doctor may decide that this infection can be treated with Lamprene®/Clofazimine. This medicine is provided to you in an expanded access program. This means that this medicine is not registered for the treatment of NTM, but it can be used in special situations where there are no other possible treatments. For example, this may be because you have a type of Mycobacterial infection that is resistant or failed to respond optimally to other drugs, or because you have had side effects that prevent the use of other drugs.
This is a Phase 2, 2-part study. Adults over the age of 18 with cystic fibrosis are eligible.
VX-152 given alone or in combination with VX-661 and ivacaftor is an investigational drug and is still being tested for safety and effectiveness. VX-661 given alone or with ivacaftor is investigational and is still being tested for safety and effectiveness. Ivacaftor, the third drug used in this study is approved in a number of countries globally for use in patients with CF as young as 2 years, depending on the country. Ivacaftor (Kalydeco) is approved in the United States for use in patients with CF.
This study aims to test the safety and tolerability of the study drug, PTI-428, when used to treat cystic fibrosis. Approximately 36 individuals will take part study-wide and adult males and females of the ages 18-55 years old with a diagnosis of Cystic Fibrosis are eligible to participate.
There are 2 different groups within the study and depending on the group you paticipate in the study will last between 5 to 7 weeks.
The study is being used to evaluate the efficacy and safety of differing durations of IV antibiotic treatment for CF pulmonary exacerbations. Subject eligibility includes males and females 18 years of age or older. Participation in the study will take 3 visits over a period of 24 to 35 days.
