Phase II

Full title

An open-label study to assess the safety, pharmacokinetics and pharmacodynamics of inhaled PC945 in adult Cystic Fibrosis (CF) patients with persistent pulmonary Aspergillus fumigatus infection

This study tests the effects of an experimental drug PC945 in people with cystic fibrosis whose lungs are infected by the fungus Aspergillus fumigatus. PC945 may be useful in treating patients infected with Aspergillus fumigatus as, unlike the usual treatments, it is inhaled into the lung and has been designed to stay there and treat the infection. Participants will continue to be treated with their usual cystic fibrosis treatment and will also receive PC945. The amount of fungus in the patients' phlegm will be measured over the course of the study. The study will take place at multiple sites in UK and will include approximately 18 participants. The maximum study duration will be about 16 weeks.
