Verona Pharma Reports Fourth Quarter and Full Year 2022 Financial Results and Provides Corporate Update

Transformational results in Phase 3 ENHANCE program for COPD

NDA submission expected Q2 2023

Strong balance sheet to support planned US commercial launch

Conference call today at 9:00 a.m. EST / 2:00 p.m. GMT

LONDON and RALEIGH, N.C., March 07, 2023 (GLOBE NEWSWIRE) — Verona Pharma plc (Nasdaq: VRNA) (“Verona Pharma” or the “Company”), a clinical-stage biopharmaceutical company focused on respiratory diseases, announces its financial results for the fourth quarter and full year ended December 31, 2022, and provides a corporate update.

“2022 was a momentous year for Verona Pharma and most importantly for the millions of patients suffering from chronic obstructive pulmonary disease (“COPD”),” said David Zaccardelli, Pharm. D., President and Chief Executive Officer. “Supported by the groundbreaking results from our Phase 3 ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) trials, we believe ensifentrine, if approved, has the potential to change the treatment paradigm for COPD.

“With about 50% of patients experiencing symptoms for more than 24 days per month, physicians are in need of new and effective COPD therapies. The success of the ENHANCE trials advances us closer to providing ensifentrine to COPD patients, with its novel mechanism of action delivering bronchodilation and non-steroidal anti-inflammatory effects in one compound. The totality of data from clinical trials, in particular our top-line data from the ENHANCE program including improvements in lung function, symptoms and quality of life measures, and remarkable reduction in the rate and risk of COPD exacerbations, combined with ensifentrine’s favorable safety profile, support our belief in the pioneering potential of ensifentrine.

“Our clinical success enabled us to significantly strengthen our financial position through an upsized $150 million equity offering in August and a $150 million debt financing facility in October. We expect these funds to extend our cash runway through at least the end of 2025.

“Alongside our progress in 2022, our development partner Nuance Pharma received clearance from China’s Center for Drug Evaluation to begin Phase 1 and Phase 3 studies with ensifentrine for COPD in mainland China. Nuance Pharma are developing and commercializing ensifentrine in Greater China and we look forward to providing future updates.

“2023 is expected to be another pivotal year for Verona Pharma as we continue preparing for the planned commercial launch of ensifentrine in the US in 2024, if approved. We expect to submit a New Drug Application (“NDA”) to the US Food and Drug Administration (“FDA”) in the second quarter of 2023 and to release additional information from the ENHANCE trials at upcoming scientific conferences.”

Program Updates and Key Milestones

The Company’s near-term milestones include:

• Submitting an NDA to the US FDA in the second quarter of 2023 for inhaled ensifentrine for the maintenance treatment of patients with COPD.

Fourth Quarter and Recent Highlights

Clinical

• In December 2022, the Company reported positive top-line Phase 3 data from its ENHANCE-1 trial. The trial successfully met its primary and key secondary endpoints demonstrating significant improvements in lung function, symptoms and quality of life measures. In addition, ensifentrine substantially reduced the rate and risk of COPD exacerbations. Ensifentrine was well tolerated over 24 and 48 weeks.

  Pooled exacerbation data from ENHANCE-1 and ENHANCE-2 trials demonstrated that ensifentrine treatment resulted in a statistically significant 40% reduction in the rate of moderate to severe COPD exacerbations over 24 weeks compared to placebo. Additionally, ensifentrine significantly decreased the risk of a moderate/severe exacerbation by 41%.

Corporate

• In October 2022, the Company completed a $150 million debt financing facility with Oxford Finance. This replaced the $30 million facility with Silicon Valley Bank and is available upon achievement of certain clinical and regulatory milestones and other conditions.

Fourth Quarter 2022 Financial Results

• Cash position: Cash and cash equivalents at December 31, 2022, were $227.8 million (December 31, 2021: $148.4 million). Between January 1, 2023 and March 3, 2023, the Company sold 2,540,173 ADS’s under its ATM facility receiving net proceeds of $56.9 million. After giving effect to these proceeds, our pro forma cash and equivalents at December 31, 2022, was $284.7 million. The Company believes cash and cash equivalents at December 31, 2022, the proceeds from the recent ATM sales, expected cash receipts from the UK tax credit program and funding expected to become available under the $150.0 million debt facility, will enable Verona Pharma to fund planned operating expenses and capital expenditure requirements through at least the end of 2025 including the commercial launch of ensifentrine in the US, if approved.
• R&D Expenses: Research and development (“R&D”) expenses were $6.8 million for the fourth quarter ended December 31, 2022 (Q4 2021: $22.7 million). This decrease of $15.9 million was primarily due to a $16.7 million decrease in clinical trial and other development costs as the Company progressed to the later stages of the Phase 3 ENHANCE program.
• SG&A Expenses: Selling general and administrative expenses (“SG&A”) were $8.3 million for the fourth quarter ended December 31, 2022 (Q4 2021: $5.8 million). The increase of $2.5 million was primarily due to a $1.4 million increase in people-related costs and $0.5 million in commercial preparation costs.
• Net loss: Net loss was $10.5 million for the fourth quarter ended December 31, 2022 (Q4 2022: net loss $23.3 million).

Full Year 2022 Financial Results

• Revenue: Revenue of $0.5 million for the year ended December 31, 2022 is related to sales of clinical supply materials to Nuance (full year 2021: $40.0 million).
• R&D Expenses: R&D expenses were $49.3 million for the year ended December 31, 2022 (full year 2021: $79.4 million), a decrease of $30.1 million. This decrease was primarily driven by a decrease in clinical trial and other development costs of $27.9 million as the ENHANCE studies were nearing completion in 2022 and a $4.2 million decrease in share-based compensation charges.
• SG&A Expenses: SG&A expenses were $26.6 million for the year ended December 31, 2022 (full year 2021: $33.9 million), a decrease of $7.3 million. This decrease was driven primarily by a $7.1 million decrease in share-based compensation charges.
• Net loss: Net loss was $68.7 million for the year ended December 31, 2022 (full year 2021: $55.6 million).

About Verona Pharma

Verona Pharma is a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapies for the treatment of chronic respiratory diseases with significant unmet medical needs. If successfully developed and approved, Verona Pharma’s product candidate, ensifentrine, has the potential to be the first therapy for the treatment of respiratory diseases that combines bronchodilator and anti-inflammatory activities in one compound. The Company has evaluated nebulized ensifentrine in its Phase 3 clinical program ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) for COPD maintenance treatment. Ensifentrine met the primary endpoint in both ENHANCE-1 and ENHANCE-2 trials demonstrating statistically significant and clinically meaningful improvements in lung function. In addition, ensifentrine significantly reduced the rate and risk of COPD exacerbations in pooled analysis from ENHANCE-1 and ENHANCE-2. Two additional formulations of ensifentrine have been evaluated in Phase 2 studies for the treatment of COPD: dry powder inhaler (“DPI”) and pressurized metered-dose inhaler (“pMDI”). Ensifentrine has potential applications in cystic fibrosis, asthma and other respiratory diseases. For more information, please visit www.veronapharma.com.
