VRNA Verona Pharma Plc

Verona Pharma plc (Nasdaq: VRNA) (“Verona Pharma” or the “Company”) announces one oral presentation and 3 posters on additional analyses from its successful Phase 3 ENHANCE studies with Ohtuvayre (ensifentrine) for the treatment of chronic obstructive pulmonary disease (“COPD”) will be presented at the European Respiratory Society (“ERS”) International Congress 2024. The abstracts are available to conference participants on the ERS website and will be published in an upcoming issue of the peer reviewed publication, European Respiratory Journal.

Ohtuvayre (ensifentrine) is a first-in-class selective dual inhibitor of the enzymes phosphodiesterase 3 and phosphodiesterase 4 (“PDE3 and PDE4”) that combines bronchodilator and non-steroidal anti-inflammatory effects in one molecule. The therapy 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 the subgroup of patients, including reduction in the rate of exacerbation, with or without chronic bronchitis and in European patients. Additionally, a pooled analysis of patient reported outcomes and the effect of Ohtuvayre on reducing cough and sputum will also be presented.

“These analyses provide further support for Ohtuvayre’s potential to benefit a broad population of patients with COPD,” said Jadwiga Wedzicha, MD, Professor of Respiratory Medicine at the National Heart and Lung Institute, Imperial College London, UK. “The non-steroidal anti-inflammatory effects with this novel therapy are particularly beneficial and I am very excited about the impact of Ohtuvayre on COPD.”

Details of Verona Pharma’s presentations and posters are listed below and linked to the ERS 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.
