Verona Pharma Reports First Quarter 2022 Financial Results and Provides Corporate Update

Phase 3 ENHANCE-2 trial on target to report top-line COPD data in Q3 2022

James Brady joined the Board as Non-Executive Director

Conference call today at 9:00 a.m. EDT / 2:00 p.m. BST

LONDON and RALEIGH, N.C., May 03, 2022 (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 March 31, 2022, and provides a corporate update.

“During the first quarter, enrollment in our Phase 3 ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) clinical program continued and we are now close to completing recruitment for this program,” said David Zaccardelli, Pharm. D., President and Chief Executive Officer. “As of May 2, 2022, approximately 90% of subjects were randomized into ENHANCE-1.

“We are on track to report top-line data from ENHANCE-2 in the third quarter of 2022 and from ENHANCE-1 around the end of the year. The top-line data from both ENHANCE trials will include the primary endpoint, improvement in lung function as measured by average forced expiratory volume in one second (FEV₁) area under the curve (AUC) 0-12 hours post dose at week 12, as well as key secondary endpoints comprising measurements of COPD symptoms and health-related quality of life, including ER-S and SGRQ endpoints, as well as overall safety data.

“The design of the ENHANCE program was based on analysis of our Phase 2b clinical trials in subjects with moderate to severe COPD including similar entry and exclusion parameters as well as key study endpoints. To date, overall population attributes including demographics and baseline COPD characteristics including smoking history, lung function, symptoms and quality of life for subjects in the ENHANCE program are similar to those seen in the Phase 2b trials.

“Alongside our clinical progress, James Brady, former Chief Financial Officer of MedImmune, joined our board as a Non-Executive Director. James brings a wealth of leadership, strategic and commercial expertise, which will be key as we prepare to submit our planned New Drug Application (“NDA”) in the U.S. for ensifentrine and progress our commercialization and licensing strategy.”

Program Updates and Key Milestones

Based on current models of forecasted recruitment and study progression, the Company’s near-term milestones include:

• Completing enrollment of ENHANCE-1 in the second quarter of 2022. This would conclude enrollment in the Phase 3 ENHANCE program. The Company projects approximately 55-65% of subjects will be receiving background therapy in each study.
• Reporting top-line data from ENHANCE-2 in the third quarter of 2022 and from ENHANCE-1 around the end of 2022.
• Conditional upon positive results, the Company expects to submit an NDA to the US Food and Drug Administration (“FDA”) in the first half of 2023.

With the recent sanctions and other government restrictions resulting from the Russia-Ukraine conflict and the COVID-19 pandemic continuing to impact a number of clinical trial activities, the Company continues to closely monitor these timelines.

First Quarter and Recent Highlights

Clinical

• In January 2022, the Company completed enrollment in ENHANCE-2 with more than 800 subjects randomized.

Corporate

• In March 2022, Mr. James Brady joined the board as a Non-Executive Director. Mr. Brady has 30-plus-years of experience in the biopharmaceutical industry, serving in multiple leadership roles across the U.S., Europe and China during his career at AstraZeneca. Most recently, he served as Chief Financial Officer of MedImmune, the biologics discovery and development division of AstraZeneca.

First Quarter 2022 Financial Results

• Cash position: Cash and cash equivalents at March 31, 2022, were $132.8 million (December 31, 2021: $148.4 million). The Company believes cash and cash equivalents at March 31, 2022, expected cash receipts from the U.K. tax credit program and funding expected to become available under the $30.0 million debt facility, will enable Verona Pharma to fund planned operating expenses and capital expenditure requirements through at least the end of 2023.
• R&D Expenses: Research and development (“R&D”) expenses were $17.6 million for the first quarter ended March 31, 2022 (Q1 2021: $13.6 million). The increase of $4.0 million was primarily due to a $5.6 million increase in costs associated with the Phase 3 ENHANCE program partially offset by a $2.0 million reduction in share-based compensation charges.
• SG&A Expenses: Selling general and administrative expenses (“SG&A”) were $7.4 million for the first quarter ended March 31, 2022 (Q1 2021: $9.3 million). The decrease of $1.9 million was primarily driven by a decrease in share-based compensation charges of $3.1 million and a $0.6 million decrease in professional fees, partially offset by the $2.0 million charge related to the modification of the Ligand Agreement.
• Net loss: Net loss was $24.8 million for the first quarter ended March 31, 2022 (Q1 2021: net loss $21.3 million).

About Verona Pharma

Verona Pharma is a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapies for the treatment of 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 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 continues to monitor the impact of the COVID-19 pandemic on its operations and clinical trials, in particular the timelines and costs of its Phase 3 clinical program ENHANCE. 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 subjects, 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.

Russia-Ukraine Conflict

Verona Pharma is conducting its ENHANCE-1 program at a number of clinical trial sites in Russia and Europe (but not including Ukraine). The sanctions and other restrictions imposed by the U.S. and other countries as a result of the current conflict between Russia and Ukraine may impact our outsourced clinical research vendor’s ability to pay the clinical trial sites in Russia, to supply ensifentrine and equipment to the sites, or validate their trial data. If the conflict extends into other countries in Europe where our clinical trials are being conducted, our clinical trial activities in those countries may also be impacted. The Company is closely monitoring the Russia-Ukraine conflict and will provide an update if it becomes aware of any meaningful disruption to the cost and timelines of our Phase 3 program or our plans to submit an NDA for ensifentrine.
