Statistically significant improvements in lung function, symptoms and quality of life
36% reduction in rate of exacerbations over 24 weeks
Well tolerated safety profile over 48 weeks
NDA submission planned for 1H 2023
Conference call today at 8:30 a.m. EST / 1:30 p.m. GMT
LONDON and RALEIGH, N.C., Dec. 20, 2022 (GLOBE NEWSWIRE) — Verona Pharma plc (Nasdaq: VRNA) (“Verona Pharma” or the “Company”), today announces positive results of its Phase 3 ENHANCE-1 trial evaluating nebulized ensifentrine for the maintenance treatment of chronic obstructive pulmonary disease (“COPD”). The ENHANCE-1 trial successfully met its primary and key secondary endpoints demonstrating significant improvements in lung function, symptoms and quality of life measures. In addition, ensifentrine substantially reduced the rate and risk of COPD exacerbations. Ensifentrine was well tolerated over 24 and 48 weeks.
Ensifentrine is a first-in-class, selective dual inhibitor of the enzymes phosphodiesterase 3 and 4 combining bronchodilator and non-steroidal anti-inflammatory activities in one compound.

Antonio Anzueto, MD, Professor of Medicine and Section, Chief of Pulmonary at South Texas Veterans Healthcare System, commented: “These exciting results demonstrate ensifentrine’s potential to become a first-in-class bronchodilator and non-steroidal anti-inflammatory therapy for COPD. The 36% reduction in the rate of exacerbations observed over 24 weeks in symptomatic patients is impressive. Combined with the significant improvements in lung function, symptom and quality of life measures, as well as the favorable safety profile, these data confirm ensifentrine’s potential to change the treatment paradigm for COPD patients.”
David Zaccardelli, Pharm. D., Verona Pharma’s President and Chief Executive Officer, said: “We are very pleased by the successful outcome of our Phase 3 ENHANCE-1 study, bringing us another step closer to providing a much needed novel therapy for COPD patients. The totality of the ENHANCE data including improvements in lung function, symptoms, quality of life measures and reduction in exacerbations, coupled with the consistent, favorable safety profile, support our belief that ensifentrine will change the treatment paradigm for COPD. We plan to submit a New Drug Application to the US Food and Drug Administration in the first half of 2023. We would like to thank all the patients and investigators for their participation in the ENHANCE program and we look forward to keeping you updated on our progress.”
Verona Pharma plans to release additional information from the ENHANCE trials at upcoming scientific conferences.
Conference Call and Webcast Information

An electronic copy of the ENHANCE-1 results press release will also be made available today on the Company’s website.
Ensifentrine (RPL554) is an investigational, first-in-class, selective dual inhibitor of the enzymes phosphodiesterase 3 and 4 that combines bronchodilator and anti-inflammatory activities in one compound. In Phase 2 clinical studies in COPD, ensifentrine has shown significant and clinically meaningful improvements in lung function, symptoms and quality of life as a monotherapy or added onto a maintenance bronchodilator. In the Phase 3 ENHANCE-1 and ENHANCE-2 clinical trials, ensifentrine showed significant and clinically meaningful improvements in lung function measures and reduced the rate of COPD exacerbations. Ensifentrine has been well tolerated in clinical trials involving approximately 3,000 subjects to date.
About the ENHANCE program
The two randomized, double-blind, placebo-controlled studies (ENHANCE-1 and ENHANCE-2) evaluated the efficacy and safety of nebulized ensifentrine as monotherapy and added onto a single bronchodilator, either a LAMA or a LABA, compared to placebo, and approximately 20% of subjects received ICS. The two study designs replicated measurements of efficacy and safety data over 24 weeks and ENHANCE-1 also evaluated longer-term safety over 48 weeks.

About Verona Pharma
Verona Pharma is a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapies for the treatment of respiratory diseases with significant unmet medical needs. If successfully developed and approved, Verona Pharma’s product candidate, ensifentrine, has the potential to be the first therapy for the treatment of respiratory diseases that combines bronchodilator and anti-inflammatory activities in one compound. The Company has evaluated nebulized ensifentrine in its Phase 3 clinical program ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) for COPD maintenance treatment. Ensifentrine met the primary endpoint in both ENHANCE-1 and ENHANCE-2 trials demonstrating statistically significant and clinically meaningful improvements in lung function. In addition, ensifentrine significantly reduced the rate of COPD exacerbations in ENHANCE-1 and ENHANCE-2. Two additional formulations of ensifentrine are in Phase 2 development for the treatment of COPD: dry powder inhaler and pressurized metered-dose inhaler. Ensifentrine also has potential applications in cystic fibrosis, asthma and other respiratory diseases. For more information, please visit www.veronapharma.com.
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 development of ensifentrine and plans to release data from the ENHANCE trials at future scientific conferences, the goals and design of clinical trials, planned regulatory submissions and timing thereof, including the timing of submission of an NDA to the FDA for ensifentrine, the potential for ensifentrine to be the first therapy for the treatment of respiratory diseases to combine bronchodilator and anti-inflammatory effects in one compound, the potential impact of ensifentrine for COPD patients and the treatment of COPD, and the potential of ensifentrine in the treatment of cystic fibrosis, asthma and other respiratory diseases.
