LONDON and RALEIGH, N.C., Aug. 03, 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 second quarter ended June 30, 2023, and provides a corporate update.

“In June, we submitted a New Drug Application (“NDA”) to the US Food and Drug Administration (“FDA”) for approval of ensifentrine for the maintenance treatment of patients with chronic obstructive pulmonary disease ("COPD"),” said David Zaccardelli, Pharm. D., President and Chief Executive Officer. “This brings us an important step closer towards providing this novel compound to the millions of symptomatic COPD patients in need of a new effective treatment approach. The FDA is expected to make a decision on acceptance of the NDA in the third quarter."

“Also in June, the American Journal of Respiratory and Critical Care Medicine ("AJRCCM"), published results from the successful Phase 3 ENHANCE trials. The data demonstrated ensifentrine improved lung function, symptoms and quality of life and substantially reduced the rate and risk of COPD exacerbations with a favorable safety profile. We are looking forward to presenting additional analyses from the ENHANCE program at the European Respiratory Society International Congress and at CHEST Annual Meeting later this year."

Program Updates and Key Milestones

The Company’s near-term planned milestones include:

• In the third quarter of 2023, the US FDA is expected to make a decision on acceptance of the Company's NDA for inhaled ensifentrine for the maintenance treatment of patients with COPD.
• Also in the third quarter of 2023, the Company plans to continue to advance its commercialization efforts across medical affairs, marketing, commercial operations, IT and CMC as well as other departments to support the planned launch of ensifentrine in 2024, subject to the approval of the NDA.
• In the second half of 2023, the Company plans to present further analyses from the Phase 3 ENHANCE trials at the European Respiratory Society International Congress 2023 and at CHEST Annual Meeting 2023.
• Also in the second half of 2023, the Company plans to host an analyst meeting providing an overview of its commercial launch plans.

Second Quarter and Recent Highlights

• In June 2023, the Company submitted a NDA to the US FDA for ensifentrine for the maintenance treatment of patients with COPD.
• Also in June 2023, the American Journal of Respiratory and Critical Care Medicine (“AJRCCM”) published results from the successful Phase 3 ENHANCE trials evaluating ensifentrine in COPD.
• In May 2023, the Company presented 12 abstracts and a symposium on expanded analyses of the ENHANCE studies with ensifentrine for the treatment of COPD at the American Thoracic Society International Conference ("ATS") 2023. The abstracts are published on the ATS website and in the AJRCCM.

Second Quarter 2023 Financial Results

• Cash position: Cash and cash equivalents at June 30, 2023, were $270.7 million (December 31, 2022: $227.8 million). The Company believes cash and cash equivalents at June 30, 2023, 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 a net reversal of $2.5 million for the second quarter ended June 30, 2023 (Q2 2022: costs of $15.0 million). R&D expenses were significantly lower in 2023 versus in 2022 as study conduct in the Phase 3 ENHANCE program completed late in 2022 with data analysis and wind-down expenses in Q2 2023. In addition, the Company favorably resolved a matter with a supplier, as well as certain disputed invoices, in Q2 2023 resulting in the reversal of approximately $6.3 million of costs accrued in prior periods, which resulted in net negative R&D expense for the three months ended June 30, 2023.
• SG&A Expenses: Selling general and administrative expenses (“SG&A”) were $12.4 million for the second quarter ended June 30, 2023 (Q2 2022: $5.5 million). This increase was primarily due to a $5.0 million increase in people related costs, inclusive of share-based compensation, as well as an increase of $1.7 million for costs related to the build out of commercial and information technology infrastructure in preparation for a potential commercial launch. The Company expects SG&A expenses to continue to be the main driver of expense as Verona Pharma prepares for a potential commercial launch in 2024.
• Net loss: Net loss was $8.8 million for the second quarter ended June 30, 2023 (Q2 2022: net loss $17.8 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 non-sterodial 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 substantially reduced the rate and risk of COPD exacerbations in pooled analysis from ENHANCE-1 and ENHANCE-2. In the second quarter of 2023, Verona Pharma submitted a New Drug Application (“NDA”) to the US Food and Drug Administration (“FDA”) for ensifentrine for the maintenance treatment of patients with COPD. 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.
