Verona Pharma Initiates U.S. Clinical Pharmacokinetic Study for RPL554 Following Acceptance of IND Application by FDA


LONDON, June 05, 2017 (GLOBE NEWSWIRE) -- Verona Pharma plc (AIM:VRP) (NASDAQ:VRNA) (“Verona Pharma”), a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapeutics for the treatment of respiratory diseases with significant unmet medical needs, announces today the initiation of a clinical pharmacokinetic trial in the United States for the Company's product candidate, RPL554, following the acceptance of an Investigational New Drug application (“IND”) by the U.S. Food and Drug Administration (“FDA”).  The first subjects have been enrolled and dosed in the study.

RPL554 is a first-in-class, inhaled, dual inhibitor of the enzymes phosphodiesterase 3 and 4 designed to have anti-inflammatory as well as bronchodilator properties, and is currently in development for the treatment of chronic obstructive pulmonary disease (“COPD”) and cystic fibrosis (“CF”).

This complete block two-way crossover trial will investigate the oral bioavailability and pharmacokinetics (“PK”) of nebulized RPL554 in 12 healthy volunteers. The study will also assess the tolerability and safety of single nebulized doses of RPL554. The oral bioavailability examines the potential contribution arising from the absorption of the swallowed portion of a nebulized dose of RPL554 to its systemic bioavailability. Top-line data is expected in the fourth quarter 2017.

“We are pleased that the IND for RPL554 has been accepted by the FDA and to initiate clinical studies with RPL554 in the United States", said Jan-Anders Karlsson, PhD, CEO of Verona Pharma. "This study will support further development of RPL554 to address unmet clinical needs in patients suffering from COPD and other debilitating respiratory diseases.”
