VRNA Verona Pharma Plc

Verona Pharma plc (Nasdaq: VRNA) (“Verona Pharma” or the “Company”) announces four oral presentations and two posters on analyses from its successful Phase 3 ENHANCE studies with Ohtuvayre (ensifentrine) for the treatment of chronic obstructive pulmonary disease (“COPD”) will be presented at CHEST Annual Meeting (“CHEST”) 2024. The analyses are published in the CHEST Annual Meeting on-line supplement.

Ohtuvayre (ensifentrine) is a first-in-class selective dual inhibitor of the enzymes phosphodiesterase three and phosphodiesterase 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 analyses will summarize the efficacy and safety of Ohtuvayre in subgroups of COPD patients including data supporting improvements in lung function, symptoms and quality of life, as well as reductions in the rate of exacerbations, regardless of COPD severity (moderate or severe), smoking status (current or former), and chronic bronchitis (with or without). Furthermore, an analysis of ensifentrine’s impact on reducing exacerbation rates and COPD-related healthcare resource utilization over 48 weeks will also be presented.

“Ensifentrine is a remarkable addition to COPD therapy,” said William Stringer, MD, FCCP, Professor of Medicine in the David Geffen School of Medicine at UCLA. “It has the capacity to bronchodilate, reduce inflammation, augment mucociliary clearance, and reduce exacerbations in smokers and former smokers.”

Details of Verona Pharma’s presentations and posters are listed below and linked to the CHEST website. In addition, the Company will present five presentations that will highlight the unmet need in COPD based on real world claims data.

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.
