About RPL554 for the treatment of COPD and Asthma Verona's lead drug, RPL554, is a dual phosphodiesterase (PDE) 3 and 4 inhibitorbeing developed as a novel treatment for chronic obstructive airways diseasesuch as COPD and asthma with bronchodilator and anti-inflammatory effects. Botheffects are essential to improve symptoms in patients with COPD or asthma.RPL554 is currently in Phase II for both diseases. COPD is a chronic lung disease with significant unmet need for which currenttreatment is far from optimal, as it often has unwanted side-effects and/orlimited effectiveness. COPD is most commonly characterised by fixed airflowobstruction and chronic airways inflammation resulting from exposure toirritants like tobacco smoke. Asthma, which remains one of the most commonchronic diseases in the world, is characterised by recurrent breathing problemsand symptoms such as breathlessness, wheezing, chest tightness, and coughing.The combined market for COPD and asthma drugs is currently estimated to beGBP20 billion (source: visiongain).
