VRNA Verona Pharma Plc

Verona Pharma plc (Nasdaq: VRNA) (“Verona Pharma” or the “Company”), a biopharmaceutical company focused on respiratory diseases, announces preliminary unaudited net product sales for the fourth quarter and full year ended December 31, 2024, and provides a corporate update.

“2024 was another transformational year for Verona with the approval and US launch of Ohtuvayre (ensifentrine) for the maintenance treatment of chronic obstructive pulmonary disease (“COPD”),” said David Zaccardelli, Pharm. D., President and Chief Executive Officer. “We are very pleased to report the exceptionally strong start to the launch of Ohtuvayre continues with more than 3,500 unique healthcare professionals (“HCPs”) prescribing Ohtuvayre and over 16,000 prescriptions filled of which approximately one-third were patient refills in 2024. During these initial 20 weeks, key metrics showed month over month growth including number of unique prescribers, new patient prescriptions, refill prescriptions, and net sales while maintaining approximately two weeks of inventory at the specialty pharmacies. Specifically, filled prescriptions increased by over 35% each month in the fourth quarter and physicians continued to prescribe Ohtuvayre across a broad COPD population including those receiving background single, dual and triple therapy.

“We recorded net product sales of approximately $36 million in the fourth quarter and $42 million for full year 2024. While it is still early in the launch, feedback from HCPs and patients is consistently positive including robust refill rates, and increasing prescriber depth with over 150 HCPs prescribing Ohtuvayre to more than 20 patients in their practice. These trends reinforce our belief that Ohtuvayre’s bronchodilator and non-steroidal anti-inflammatory activity can re-define the COPD treatment paradigm. We are excited by the initial impact of Ohtuvayre and look forward to building on this momentum in 2025.”

Program Updates and Key Milestones

• Ohtuvayre’s product specific J-code, J7601, became effective on January 1, 2025.
• In November 2024, the Company completed enrollment in a Phase 2 dose-ranging trial with glycopyrrolate, a long-acting muscarinic antagonist (“LAMA”), supporting a fixed-dose combination program for the maintenance treatment of COPD via a nebulizer. Results will support initiation of a Phase 2b trial with a fixed dose combination of ensifentrine with glycopyrrolate in the third quarter of 2025.
• The Company continues to enroll subjects in a Phase 2 trial to assess the efficacy and safety of nebulized ensifentrine in patients with non-cystic fibrosis bronchiectasis (“NCFBE”).
