What is "denufosol"

n. An inhalable drug being developed for the treatment of cystic fibrosis.

Denufosol ( INN) is an inhaled drug for the treatment of cystic fibrosis, being developed by Inspire Pharmaceuticals and sponsored by the Cystic Fibrosis Foundation. It was tested in two Phase III clinical trials, TIGER-1 and TIGER-2. Initially, in the first Phase III trial, TIGER-1, the compound showed significant results as compared with placebo. In the second Phase III trial, TIGER-2, the compound did not meet the primary endpoint, a significant change in baseline FEV1 (forced expiratory volume in one second) at the week 48 endpoint as compared to placebo. As of 2011, no additional clinical studies are being conducted with the compound.

The drug was also investigated for the treatment of retinal detachment and other retinal diseases, but trials were terminated in 2006.
