Verona Pharma Completes Enrollment in Phase 2 Clinical Trial Evaluating Nebulized RPL554 as Add-on to Dual Bronchodilator Therapy for COPD Maintenance Treatment
Enrollment complete ahead of schedule
Top line data expected in
This randomized, double-blind, three-way crossover trial is designed to investigate the efficacy and safety of nebulized RPL554 as an add-on to an inhaled LAMA/LABA, tiotropium/olodaterol (Stiolto® Respimat®), compared to placebo. Those patients already receiving inhaled corticosteroid (“ICS”) anti-inflammatory therapy will continue a stable dose of ICS throughout the study, thus providing additional data on “triple therapy” use. Following a 7- to 14-day washout period in advance of dosing and between study arms, patients will receive three days of treatment with each of two dose strengths (1.5 mg or 6.0 mg) of nebulized RPL554 or placebo twice daily. The primary endpoint of this trial is improvement in lung function with RPL554 vs placebo (as add-on to tiotropium/olodaterol), as measured by peak forced expired volume in one second (FEV1), a standard measure of exhaled breath volume to evaluate respiratory function.
“We are delighted that enrollment in this Phase 2 study has been completed ahead of schedule and now expect to report top line data in January following completion of dosing and data analysis,” stated
RPL554 is a first-in-class, inhaled, dual inhibitor of the enzymes phosphodiesterase 3 and 4 designed to have bronchodilator as well as anti-inflammatory properties, and is currently in development for the maintenance treatment of COPD and for the treatment of cystic fibrosis (“CF”).
Chronic obstructive pulmonary disease (“COPD”) is a progressive and life-threatening respiratory disease for which there is no cure.1 Although COPD is thought to be underdiagnosed, globally, around 384 million people suffer from the disease.2 This number, according to the
This press release contains forward-looking statements. All statements contained in this press release that do not relate to matters of historical fact should be considered forward-looking statements, including, but not limited to, statements regarding the design of the Phase 2 clinical trial of RPL554, the timing of availability of top-line data for the Phase 2 clinical trial, the importance of the Phase 2 clinical trial to our development plans for RPL554, the potential of RPL554 as a promising first-in-class treatment option for COPD, and the value of the data and insights that may be gathered from the Phase 2 clinical trial, including for the purpose of designing pivotal Phase 3 trials.
These forward-looking statements are based on management's current expectations. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from our expectations expressed or implied by the forward-looking statements, including, but not limited to, the following: our limited operating history; our need for additional funding to complete development and commercialization of RPL554, which may not be available and which may force us to delay, reduce or eliminate our development or commercialization efforts; the reliance of our business on the success of RPL554, our only product candidate under development; economic, political, regulatory and other risks involved with international operations; the lengthy and expensive process of clinical drug development, which has an uncertain outcome; serious adverse, undesirable or unacceptable side effects associated with RPL554, which could adversely affect our ability to develop or commercialize RPL554; potential delays in enrolling patients, which could adversely affect our research and development efforts and the completion of our Phase 2 trial; we may not be successful in developing RPL554 for multiple indications; our ability to obtain regulatory approvals necessary to conduct later stage trials and to commercialize RPL554 in multiple major pharmaceutical markets; misconduct or other improper activities by our employees, consultants, principal investigators, and third-party service providers; material differences between our “top-line” data and final data; our reliance on third parties, including clinical investigators, manufacturers and suppliers, and the risks related to these parties’ ability to successfully develop and commercialize RPL554; and lawsuits related to patents covering RPL554 and the potential for our patents to be found invalid or unenforceable.
