Board strengthened with NED appointment of Lisa Deschamps

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

LONDON and RALEIGH, N.C., April 29, 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 March 31, 2021, and provides a corporate update.

"The first quarter of 2021 set a positive tone for what we expect to be another exciting year of substantial progress for Verona Pharma," said David Zaccardelli, Pharm. D., President and Chief Executive Officer. "Patient recruitment is ongoing in our Phase 3 ENHANCE ("Ensifentrine as a Novel inHAled Nebulized COPD thErapy") clinical program. Based on our projections, we continue to expect to complete enrollment in both studies in the second half of 2021 and to report top-line data from ENHANCE-2 in the first half of 2022 and from ENHANCE-1 in the second half of 2022.

"We have already reported results from two clinical studies this year. In February, we reported positive Phase 2 results with the pressurized metered-dose inhaler ("pMDI") formulation of ensifentrine in moderate to severe COPD patients, and, last week, we reported that data from a pilot study with pMDI ensifentrine showed that ensifentrine added on to standard of care was well tolerated in patients hospitalized with COVID-19. The study was not powered to identify statistically significant efficacy outcomes and no benefit with ensifentrine added on to standard of care was observed.

"In addition to this clinical progress, we strengthened our board with the Non-Executive Director appointment of Lisa Deschamps, Senior Vice President, Chief Business Officer, Novartis Gene Therapies. Lisa's strategic and commercial expertise will be valuable as we progress ensifentrine through Phase 3 trials and prepare for commercialization."

First Quarter and Recent Highlights

Clinical

• In April 2021, Verona Pharma reported that results from the pilot study with pMDI ensifentrine showed ensifentrine added on to standard of care was well tolerated in patients hospitalized with COVID-19. The study was not powered to identify statistically significant efficacy outcomes and no clinical efficacy benefit with ensifentrine added on to standard of care was observed. The Company does not currently plan to conduct further studies of ensifentrine in the treatment of COVID-19.
• In February 2021, Verona Pharma announced positive Phase 2 efficacy and safety data with pMDI ensifentrine in patients with moderate to severe COPD. The primary and secondary lung function endpoints were achieved and the data support further evaluation of twice-daily dosing. All three inhaled formulations have demonstrated statistically significant improvements in lung function in COPD patients, supporting the broad potential of ensifentrine delivered via nebulizers and handheld inhalers.

Corporate

• In March 2021, Ms. Lisa Deschamps joined the board as a Non-Executive Director. Ms. Deschamps is Senior Vice President, Chief Business Officer, of Novartis Gene Therapies. She has significant global and US experience in bringing respiratory and other specialized therapeutic area products to the market.
  
  

Upcoming Key Milestones

The Company's near-term milestones include:

• Presenting three abstracts demonstrating positive safety, symptom and quality of life data from Phase 2b clinical studies with nebulized ensifentrine in COPD at the American Thoracic Society International Conference ("ATS") here in May 2021.

• Based on recruitment projections, the Company expects to complete enrollment in both Phase 3 trials, ENHANCE-1 and ENHANCE-2, with the nebulized formulation of ensifentrine for the maintenance treatment of COPD in the second half of 2021. With the pandemic and government and other measures in response impacting a number of clinical trial activities, the Company continues to monitor these timelines.
• Longer term, based on forecasted recruitment and study progress, the Company expects to announce top-line data from ENHANCE-2 in the first half of 2022 and from ENHANCE-1 in the second half of 2022.
  
  

First Quarter 2021 Financial Results

• Cash position: Cash and cash equivalents at March 31, 2021, were $169.6 million (December 31, 2020: $188.0 million). The Company believes our cash and cash equivalents at March 31, 2021, together with funding expected to become available under the $30.0 million debt financing facility secured in November 2020 and from cash receipts from U.K. tax credits, will enable us to fund our planned operating expenses and capital expenditure requirements into 2023.
• R&D Expenses: Research and development ("R&D") expenses were $13.6 million for the first quarter ended March 31, 2021 (Q1 2020: R&D expenses $7.6 million). The increase was primarily due to costs associated with the Phase 3 ENHANCE program as well an increase in share-based compensation charges.
• G&A Expenses: General and administrative expenses ("G&A") were $9.3 million for the first quarter ended March 31, 2021 (Q1 2020: G&A expenses $6.9 million). This increase was driven by an increase in share-based compensation charges, partially offset by executive change costs in the prior period.
• Net loss: Net loss was $21.3 million for the first quarter ended March 31, 2021 (Q1 2020: net loss $12.3 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 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 are impacting 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).

Verona Pharma is closely monitoring activities at the Company's contract manufacturers associated with clinical supply for the ongoing clinical trials, and is satisfied that appropriate plans and procedures are in place to ensure uninterrupted future supply of ensifentrine to the clinical trial sites, subject to potential limitations on their operations and on the supply chain due to the COVID-19 pandemic. The Company is continuing to monitor this situation and will provide an update if it becomes aware of any meaningful disruption caused by the pandemic to the clinical supply of ensifentrine for its clinical trials.

Verona Pharma has also implemented measures to help keep the Company's employees, families, and local communities healthy and safe. All employees are working remotely and all business travel has been restricted.
