Verona Pharma Receives Authorization from the U.S. FDA to Proceed with Clinical Investigation of RPL554 with the Acceptance of Investigational New Drug Application



18 April 2017, London - Verona Pharma plc (AIM: VRP) ("Verona Pharma" or the "Company"), a clinical-stage biopharmaceutical company focused on developing and commercialising innovative therapeutics for the treatment of respiratory diseases, announced today that the U.S. Food and Drug Administration has authorized the initiation of a pharmacokinetic ("PK") clinical trial in the U.S. for the Company's product candidate, RPL554, with the acceptance of an Investigational New Drug application ("IND").   


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, currently in development for the treatment of chronic obstructive pulmonary disease and cystic fibrosis.


With the IND effective, the Company plans to initiate a PK clinical trial in the middle of this year in approximately 12 healthy volunteers to determine the oral bioavailability of RPL554, as well as assess the safety and tolerability of the drug. Top-line data is expected in the fourth quarter of 2017.


"We look forward to initiating the first clinical trial with RPL554 in the U.S.," said Jan-Anders Karlsson, PhD, CEO of Verona Pharma. "This important regulatory milestone reinforces Verona Pharma's commitment to bring a novel therapeutic option with both bronchodilator and anti-inflammatory effects to patients with chronic, debilitating respiratory conditions that are not well treated by existing medicines."
