The type of treatment or therapy being studied. A therapy could range from a medication addressing a particular characteristic of CF to a device or activity e.g. exercise
The different stages involved in the development of a new medication. Phase I focuses on initial safety in people. Phase 2 evaluates safety, correct dose and early signs of whether the medication works. Phase 3 is the stage before medication licensing and looks at safety and medication effectiveness. Phase 4 evaluates longer term use of a medication after it has been licensed for use
A Phase IIa, randomised, double blind, placebo controlled, three way crossover study to assess the pharmacokinetics of RPL554 administered to adult patients with Cystic Fibrosis.
The study drug, called RPL554, is a potential new inhaled drug that is being developed for the treatment of breathing and lung diseases, including cystic fibrosis.
The study drug is a liquid that is breathed in using a device called a nebuliser, which is a commonly used device that turns a liquid into a fine mist that can then be inhaled into the lungs where it can then be taken into the body. Over 240 people have been given RPL554 in clinical studies so far. Two different formulations (how the drug is made up) have been tested in these studies; 105 people have received the original formulation of RPL554 and 144 have received either one dose or up to 11 doses (between 0.4 mg and 24 mg) of a newer formulation of RPL554. If you decide to take part in this study, you will be given two different doses (1.5 mg and 6 mg) of this newer formulation RPL554. You will also be given a placebo (a dummy drug containing the same inactive ingredients as RPL554 but no active ingredients).
The main purpose of this study is to look at the effect your body has on the study drug by measuring the amount of RPL554 in your blood (this is called “pharmacokinetics”). The study will also investigate how much RPL554 can open up the airways (bronchodilation), what effect it has on inflammation and what side effects it has.
