Verona Pharma Reports Third Quarter 2021 Financial Results and Provides Corporate Update

Enrollment in ENHANCE-1 48-week subset and ENHANCE-2 expected to complete around year-end 2021

ENHANCE Phase 3 program on track to report top-line data in 2022

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

LONDON and RALEIGH, N.C., Nov. 09, 2021 (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 three months ended September 30, 2021, and provides a corporate update.

“During the third quarter, we continued to make substantial progress on patient recruitment in our Phase 3 ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) clinical program,” said David Zaccardelli, Pharm. D., President and Chief Executive Officer. “We are excited to report patient enrollment is nearing completion and expect that by the end of November both the 800 patient ENHANCE-2 trial and the 400 patient 48-week subset of the ENHANCE-1 trial will be approximately 95% enrolled.

“We are pleased with our ability to advance recruitment in these international, multi-site clinical trials during a global pandemic. Although the pace of enrollment is expected to slow due to the approaching holiday season and the continued effects of the COVID-19 pandemic, we still expect to complete enrollment in ENHANCE-2 and the 48-week subset of ENHANCE-1 around year-end 2021. We expect to report top-line data from ENHANCE-2 mid-year 2022 and from ENHANCE-1 around the end of 2022.”

Program Updates and Key Milestones

As of November 8, 2021, ENHANCE-2 had approximately 90% of patients randomized into the study. Including those patients currently entered in the run-in period, we expect ENHANCE-2 to be approximately 95% enrolled by the end of November 2021.

The 48-week subset of ENHANCE-1 is a critical driver of delivering top-line data. As of November 8, 2021, this subset had approximately 95% of patients randomized into the study.

The Company’s near-term milestones include:

• In mid-November, Ms. Caroline Diaz will join Verona Pharma as Senior Vice President of Regulatory Affairs, bringing more than 18 years of experience in both large and small pharmaceutical companies across key regions. Ms. Diaz has served at ReViral as Vice President, Regulatory Affairs, and, previously, as Vice President, Regulatory and Quality at Dova Pharmaceuticals where she built the regulatory function from the ground up and led regulatory strategy development and implementation efforts resulting in the first marketing approvals for the company.
• In December 2021, the Company expects to report results from a 32-patient thorough QT study to evaluate the effect of ensifentrine on measures of cardiac conduction, which the Company is carrying out in support of a potential NDA submission.
• Based on our current models of forecasted recruitment and study progress the Company expects:
  • Enrollment of ENHANCE-2 and the 48-week subset of ENHANCE-1 to complete around year-end 2021. Enrollment in the full ENHANCE-1 trial is expected to complete in the second quarter of 2022.
  • Top-line data for ENHANCE-2 mid-year 2022 and for ENHANCE-1 around the end of 2022.
  • Should COVID-19 related challenges increase further, our models predict top-line data for ENHANCE-2 would be expected in the third quarter of 2022 and for ENHANCE-1 in the first quarter of 2023. With the COVID-19 pandemic and government and other measures continuing to impact a number of clinical trial activities, including contractor staffing issues and disruptions to supply chains globally, the Company continues to closely monitor these timelines.

Third Quarter and Recent Highlights

Clinical

• In October 2021, the Company presented Phase 2 data demonstrating the positive effect of a pressurized metered-dose inhaler (“pMDI”) formulation of ensifentrine in COPD at the CHEST Annual Meeting 2021. Data from Part B of the two-part study, first reported in February 2021, showed ensifentrine delivered by pMDI over one week provided statistically significant, clinically meaningful and dose-dependent improvements in lung function and was well tolerated. The data with delivery via pMDI are consistent with results for dry powder inhaler (“DPI”) and nebulizer formulations of ensifentrine and underline the suitability of ensifentrine for delivery to the lung via all three primary inhalation delivery platforms.
• In September 2021, the Company presented an abstract describing the results of a Phase 1 study assessing the effect of CYP2C9 inhibitor, fluconazole, on the pharmacokinetics of ensifentrine in healthy individuals at the European Respiratory Society International Congress (“ERS”) 2021. Ensifentrine is primarily metabolized via the hepatic route by the cytochrome P450 enzyme, CYP2C9. Results from the study demonstrated co-administration of fluconazole had a less than 2-fold, not clinically relevant, effect on pharmacokinetic measures of the maximum concentration and area under the curve for ensifentrine.

Third Quarter 2021 Financial Results

• Cash position: Cash and cash equivalents at September 30, 2021, were $166.5 million (June 30, 2021: $146.0 million). We believe our cash and cash equivalents at September 30, 2021, expected cash receipts from the U.K. tax credit program and funding expected to become available under the $30.0 million debt financing facility secured in November 2020, will enable us to fund our planned operating expenses and capital expenditure requirements through at least the end of 2023.

• Revenue: Revenue for the third quarter ended September 30, 2021, was $40.0 million (Q3 2020: $nil). This revenue was recognized from our agreement with Nuance Pharma for the development and commercialization of ensifentrine in Greater China (the “Nuance Agreement”).
• R&D Expenses: Research and development (“R&D”) expenses were $22.6 million for the third quarter ended September 30, 2021 (Q3 2020: R&D expenses $12.8 million). The increase of $9.8 million was primarily due to costs associated with the Phase 3 ENHANCE program partially offset by a reduction in share-based compensation charges.
• S,G&A Expenses: Selling, general and administrative expenses (“S,G&A”) were $10.9 million for the third quarter ended September 30, 2021 (Q3 2020: S,G&A expenses $8.3 million). This increase of $2.6 million was driven primarily by costs relating to the Nuance Agreement, partially offset by a reduction in costs relating to the July 2020 PIPE financing.
• Net profit/(loss): Net profit was $11.1 million for the third quarter ended September 30, 2021 (Q3 2020: net loss $18.9 million) and the net cash generated by operating activities for the quarter was $22.8 million.

The Company is evaluating nebulized ensifentrine in its Phase 3 clinical program ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) for COPD maintenance treatment. Two additional formulations of ensifentrine are in Phase 2 development 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.

COVID-19 Impact

Verona Pharma is closely monitoring the potential impact of the COVID-19 pandemic on its operations and clinical trials, in particular the timelines and costs of its Phase 3 ENHANCE clinical program. The pandemic and government and other measures in response continue to impact a number of clinical trial activities and the Company will provide an update if it becomes aware of any meaningful disruption caused by the pandemic to its clinical trials.

To help protect the health and safety of the patients, caregivers and healthcare professionals involved in its clinical trials, as well as its employees and independent contractors, the Company continues to follow guidance from the FDA and other health regulatory authorities regarding the conduct of clinical trials during the COVID-19 pandemic to ensure the safety of study participants, minimize risks to study integrity, and maintain compliance with good clinical practice (GCP).

The COVID-19 pandemic is disrupting supply chains, and employee retention and recruitment, globally and the Company is closely monitoring this situation and will provide an update if it becomes aware of any meaningful disruption caused by the pandemic to the supply of ensifentrine and drug-related products, equipment and services for its clinical trials.
