Trial status

Open to recruitment

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

Phase IV

Full title

Aztreonam for inhalation for the treatment of acute exacerbations in cystic fibrosis. An open-label, randomised, cross-over pilot study of AZLI plus intravenous Colistin versus standard dual intravenous therapy.

This study’s primary objective is to investigate whether there is immediate clinical benefit in the use of Cayston® in acute exacerbations of CF. Repeated courses of antibiotics via a drip (also known as intravenous or IV antibiotics) can cause long-term side effects including deafness and chronic kidney disease. It is therefore important to explore newer approaches for treating chest infections in CF. Nebulised antibiotics provide an opportunity to deliver antibiotics straight to the lungs with significantly less of the drug being absorbed into the blood stream. This means that potential side effects and long-term damage to other organs are minimised. Furthermore nebulised antibiotics are generally well tolerated, less invasive and require less time to administer. AZTEC-CF aims to evaluate whether inhaled antibiotic treatment is beneficial in the treatment of acute chest infections
