Glycopyrrolate

OhtuvayreTM (ensifentrine) recorded net product sales of $36.6 million in Q4 and $42.3 million in 2024 More prescriptions filled through February 2025 than in Q4 2024 Over 4,600 unique prescribers with ~55% of Tier 1 HCPs prescribing Ohtuvayre through February 2025 Phase 2 programs in bronchiectasis and fixed-dose combination in COPD advance Conference call today at 9:00 a.m. EST / 2:00 p.m. GMT LONDON and RALEIGH, N.C., Feb. 27, 2025 (GLOBE NEWSWIRE) — Verona Pharma plc (Nasdaq: VRNA) (“Verona Pharma” or the “Company”), a biopharmaceutical company focused on respiratory diseases, announces its financial results for the fourth quarter and full year ended December 31, 2024, and provides a corporate update. “2024 was another transformational year for Verona Pharma with the US approval and launch of Ohtuvayre (ensifentrine), the first novel inhaled therapy available for the maintenance treatment of Chronic Obstructive Pulmonary Disease (“COPD”) in over 20 years,” said David Zaccardelli, Pharm. D., President and Chief Executive Officer. “We are very pleased to report the extremely strong start to the launch continues to build momentum with more prescriptions dispensed through February 2025 than in the entire fourth quarter of 2024. “More than 4,600 unique healthcare professionals (“HCPs”) including approximately 55% of our Tier 1 HCPs have prescribed Ohtuvayre. Additionally, to date, more than 275 HCPs have prescribed Ohtuvayre to over 20 patients in their practice. Ohtuvayre is being prescribed for maintenance therapy across a broad COPD population including those receiving background single, dual and approximately 50% on triple therapy. These data strengthen our belief that ensifentrine’s novel bronchodilator and non-steroidal anti-inflammatory activity will redefine the treatment paradigm for COPD. “Alongside our commercialization efforts, in the third quarter we initiated two Phase 2 clinical trials: a dose-ranging trial with glycopyrrolate, a long-acting muscarinic antagonist (“LAMA”), to support a nebulized fixed-dose combination of ensifentrine and glycopyrrolate for the maintenance treatment of COPD, and a study assessing the safety and efficacy of nebulized ensifentrine in patients with non-cystic fibrosis bronchiectasis (“bronchiectasis”). We are pleased to report the glycopyrrolate dose-ranging trial was successfully completed and we plan to initiate a dose ranging Phase 2b trial with a fixed-dose combination of ensifentrine and glycopyrrolate in the second half of 2025. “In addition to our successful Ohtuvayre launch, our development partner in Greater China, Nuance Pharma, announced in February 2025 that Ohtuvayre was approved in Macau, the first approval outside of the US, for the maintenance treatment of COPD. In addition, Nuance Pharma has completed enrollment in its own pivotal Phase 3 trial in China to evaluate ensifentrine for the maintenance treatment of COPD and expects to report results in mid-2025. “In 2025, we will continue to build on the successful commercialization of Ohtuvayre in the US while progressing our Phase 2 programs. We are also initiating activities with regulatory authorities in the European Union and the UK for potential marketing authorization application submissions for Ohtuvayre.” Program Updates and Key Milestones The Company’s near-term milestones include: In the second half of 2025, the Company plans to start a dose-ranging Phase 2b trial to assess the safety and efficacy of a fixed-dose nebulized combination of ensifentrine with glycopyrrolate. The Company has successfully completed a Phase 2 dose-ranging trial with glycopyrrolate to support this program. The Company continues to enroll subjects in a Phase 2 trial to assess the efficacy and safety of nebulized ensifentrine in patients with bronchiectasis. In 2025, the Company plans to progress the regulatory activities for potential marketing authorization application submissions for Ohtuvayre for the maintenance treatment of COPD in the European Union and in the UK. In mid-2025, the Company’s development partner in Greater China, Nuance Pharma, is expected to report results from its pivotal Phase 3 trial evaluating ensifentrine for the maintenance treatment of COPD in China. Fourth Quarter and Recent Highlights In October 2024, the Company gave four oral presentations and presented two posters on analyses from the ENHANCE studies at CHEST Annual Meeting 2024. These included subgroup 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). An analysis of Ohtuvayre’s impact on reducing exacerbation rates and COPD-related healthcare resource utilization was also presented. In November 2024, the 2025 GOLD report added Ohtuvayre to the COPD treatment algorithm. Also in November 2024, the Company completed enrollment in a Phase 2 dose-ranging trial with glycopyrrolate, a LAMA, supporting a fixed-dose combination program for the maintenance treatment of COPD via a nebulizer. On January 1, 2025, Ohtuvayre’s product specific J-code became effective. In February 2025, the Company’s development partner in Greater China, Nuance Pharma, announced Ohtuvayre has been approved in Macau for the maintenance treatment of COPD in adult patients. This is the first regulatory approval outside of the US. Fourth Quarter 2024 Financial Results Cash position: Cash and cash equivalents at December 31, 2024, were $399.8 million (December 31, 2023: $271.8 million). Product sales: Net sales of Ohtuvayre were $36.6 million for the fourth quarter ended December 31, 2024 (Q4 2023: $0 million). The Company received FDA approval on June 26, 2024 and the product was commercially available beginning in August 2024. Cost of sales: Cost of sales was $2.0 million for the fourth quarter ended December 31, 2024 (Q4 2023: $0 million), which included Ohtuvayre manufacturing costs incurred after US approval, inventory overhead costs and sales-based royalties. R&D Expenses: Research and development (“R&D”) expenses were $7.9 million for the fourth quarter ended December 31, 2024 (Q4 2023: $4.1 million). This increase of $3.8 million was primarily due to an increase of $3.2 million in clinical trial and other development costs as we initiated two Phase 2 studies in the third quarter of 2024 related to the combination of nebulized ensifentrine and glycopyrrolate and for Ohtuvayre in patients with bronchiectasis, and an increase of $1.1 million in share-based compensation. SG&A Expenses: Selling general and administrative expenses (“SG&A”) were $45.1 million for the fourth quarter ended December 31, 2024 (Q4 2023: $15.0 million). The increase of $30.1 million was driven primarily by an increase of $9.8 million in marketing and other commercial related activities, including travel, primarily related to the launch of Ohtuvayre, and an increase of $2.6 million in professional and consulting fees, information technology costs and other support costs due to the continued buildout of our commercial organization. Additionally, we had an increase of $8.8 million in people-related costs as we built out our commercial organization including much of the field sales team as well as an increase of $7.8 million related to share-based compensation. Net loss: Net loss was $33.8 million for the fourth quarter ended December 31, 2024 (Q4 2023: Net loss $14.1 million). Full Year 2024 Financial Results Product sales: Net sales were $42.3 million for the year ended December 31, 2024 (2023: $0 million) related to product sales of Ohtuvayre. Cost of sales: Cost of sales was $2.6 million for the year ended December 31, 2024 (2023: $0 million), which included Ohtuvayre manufacturing costs incurred after US approval, inventory overhead costs and sales-based royalties. R&D Expenses: R&D expenses were $44.6 million for the year ended December 31, 2024 (full year 2023: $17.2 million), an increase of $27.4 million. This increase was primarily due to an increase of $17.5 million in clinical trial and other development costs we incurred related to the two Phase 2 studies which were initiated in the third quarter of 2024 related to the combination of nebulized ensifentrine and glycopyrrolate and for Ohtuvayre in patients with bronchiectasis, the $6.3 million approval milestone, $3.1 million increase in share-based compensation, $2.0 million increase for people-related costs and $1.1 million related to pre-launch manufacturing costs for commercial supply. This was partially offset by a decrease of $1.3 million in consultant and professional fee costs which were higher in the prior year due to service costs associated with our New Drug Application and the related approval process. SG&A Expenses: SG&A expenses were $149.8 million for the year ended December 31, 2024 (full year 2023: $50.4 million), an increase of $99.4 million. This increase was driven primarily by an increase of $29.7 million in marketing and other commercial related activities, including travel, primarily related to the launch of Ohtuvayre, a charge of $15.0 million for the first sale milestone and an increase of $7.3 million in professional and consulting fees, information technology costs and other support costs due to the continued buildout of our commercial organization. Additionally, we had an increase of $26.8 million in people-related costs as we built out our commercial organization including much of the field sales team as well as an increase of $18.8 million related to share-based compensation. Net loss: Net loss was $173.4 million for the year ended December 31, 2024 (full year 2023: $54.4 million).
