Parion Sciences Announces Initiation of Phase 2 Clinical Study of P-1037 for the Treatment of Cystic Fibrosis

First Patient with Cystic Fibrosis Enrolled in CLEAN-CF Phase 2 Clinical Trial

Durham, NC (May 6, 2015) – Parion Sciences, a company dedicated to the development of novel treatments for pulmonary and ocular diseases, announced today it has begun enrollment of a phase 2 clinical trial of P-1037 in patients with Cystic Fibrosis (CF).

The trial has been named the “CLEAN-CF” trial which refers to “Clearing Lungs with ENaC inhibition in Cystic Fibrosis”. The CLEAN-CF study will include CF patients regardless of an individual’s genetic mutation. Inhibiting the epithelial sodium channels (ENaC) in the airways with P-1037, an “ENaC blocker,” is expected to re-hydrate the mucus layers, thus restoring airway clearance, improve lung function and, ultimately, reduce exacerbations. P-1037 has demonstrated to be long acting in preclinical models and to have a favorable safety and tolerability profile in the completed Phase 1 studies. The initiation of the Phase 2 clinical trials was supported by an award from Cystic Fibrosis Foundation Therapeutics Inc. (CFFT), the nonprofit affiliate of the Cystic Fibrosis Foundation.

People who have mucosal surface deficiencies suffer from conditions ranging from dry eye disease to life-threatening pulmonary diseases, including cystic fibrosis (CF), chronic obstructive pulmonary disease, and idiopathic pulmonary fibrosis.
