Verona Pharma to Present Seven Analyses of the Phase 3 ENHANCE Studies in COPD at ATS 2025
Analyses support Ohtuvayre® (ensifentrine) as a first-in-class selective dual
inhibitor of PDE3 and PDE4 for a broad COPD population
LONDON and RALEIGH, N.C., May 06, 2025 (GLOBE NEWSWIRE) -- Verona Pharma plc (Nasdaq: VRNA) (“Verona” or the “Company”), a biopharmaceutical company focused on respiratory diseases, announces ten posters including seven additional analyses from its Phase 3 ENHANCE studies with Ohtuvayre (ensifentrine) for the treatment of chronic obstructive pulmonary disease (“COPD”), two from nonclinical studies, and one from a real-world data analysis, will be presented at the American Thoracic Society Conference (“ATS”) 2025. The posters are published on the ATS website and in the publication, American Journal of Respiratory and Critical Care Medicine.
Ohtuvayre is a first-in-class selective dual inhibitor of the enzymes phosphodiesterase 3 and 4 (“PDE3 and PDE4”) that combines bronchodilator and non-steroidal anti-inflammatory effects in one molecule. Ohtuvayre is the first novel inhaled mechanism for the maintenance treatment of COPD in more than 20 years.
The ENHANCE posters highlight subgroup analyses of patients when used as monotherapy, in patients with COPD and comorbid cardiac disorders and, separately, in patients with COPD and comorbid type 2 diabetes. An analysis of Ohtuvayre’s effect on COPD exacerbations relative to lung function results will also be presented. Nonclinical posters describe a tissue distribution study in rat demonstrating lack of brain exposure, and a bleomycin model in rat demonstrating antifibrotic effects following inhaled ensifentrine dosing. In addition, the Company will have an exhibition booth, 2237, which will host presentations led by clinical experts.
Details of Verona’s posters are listed below and linked to the ATS website.

About Ohtuvayre (ensifentrine)
Ohtuvayre is the first inhaled therapy for the maintenance treatment of COPD that combines bronchodilator and non-steroidal anti-inflammatory activities in one molecule. Verona has evaluated nebulized Ohtuvayre in its Phase 3 clinical program ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) for COPD maintenance treatment. Ohtuvayre met the primary endpoint in both ENHANCE-1 and ENHANCE-2, demonstrating statistically significant and clinically meaningful improvements in lung function. A fixed-dose combination of ensifentrine and glycopyrrolate, a LAMA, is currently under development for the maintenance treatment of COPD.
