LONDON, March 26, 2018 (GLOBE NEWSWIRE) -- Verona Pharma plc (AIM:VRP) (Nasdaq:VRNA) (“Verona Pharma” or “the Company”), a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapies for respiratory diseases, announces today positive top-line data from its Phase 2b study evaluating RPL554, a first-in-class, inhaled, dual inhibitor of the enzymes phosphodiesterase 3 and 4 with bronchodilator and anti-inflammatory properties, as a maintenance treatment for chronic obstructive pulmonary disease (COPD).
The study met its primary endpoint, with RPL554 producing a clinically and statistically significant improvement in peak forced expiratory volume in one second (FEV1) at four weeks in patients with moderate-to-severe COPD compared to placebo. Furthermore, the peak FEV1 was significantly improved at all time points over the four weeks of dosing. Secondary endpoints measuring 12 hour average FEV1, COPD symptoms and Quality of Life were also met and support the potential clinical benefits of RPL554 for the treatment of COPD.
