Ensifentrine met primary and secondary endpoints of evaluating lung function in Phase 3 ENHANCE-2 trial for COPD

Top-line Phase 3 ENHANCE-1 data expected around the end of 2022

Conference call today at 8:30 a.m. EDT / 1:30 p.m. BST

LONDON and RALEIGH, N.C., Aug. 09, 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 June 30, 2022, and provides a corporate update.

In a separate press release issued earlier today, Verona Pharma announced positive top-line results from its Phase 3 ENHANCE-2 ("Ensifentrine as a Novel inHAled Nebulized COPD thErapy") trial evaluating nebulized ensifentrine for the maintenance treatment of chronic obstructive pulmonary disease ("COPD"). The ENHANCE-2 trial has successfully met its primary endpoint, as well as secondary endpoints demonstrating improvements in lung function, and significantly reduced the rate and risk of COPD exacerbations. Ensifentrine was well tolerated with safety results similar to placebo.

David Zaccardelli, Pharm. D., President and Chief Executive Officer, said: "We are very pleased by the successful outcome of our ENHANCE-2 study and remain committed to bringing ensifentrine to COPD patients as quickly as possible. These data, along with results from our ongoing Phase 3 trial, ENHANCE-1, which are on track to be reported around the end of 2022, if similarly positive, are expected to support the submission of a New Drug Application to the US Food and Drug Administration in the first half of 2023. We want to thank all the patients and investigators for their participation in the trial to advance ensifentrine as a potential new therapy for the treatment of COPD."

Program Updates and Key Milestones

Based on current models of study progression, the Company's near-term milestones include:

Reporting top-line data from ENHANCE-1 around the end of 2022.
Conditional upon positive results, the Company expects to submit a New Drug Application ("NDA") to the US Food and Drug Administration ("FDA") in the first half of 2023 for inhaled ensifentrine for the maintenance treatment of COPD.

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.

Second Quarter and Recent Highlights

Clinical

In August 2022, the Company reported positive top-line Phase 3 data from ENHANCE-2. The trial successfully met its primary endpoint and secondary endpoints evaluating lung function. Ensifentrine also significantly reduced the rate and risk of COPD exacerbations. Ensifentrine was well tolerated with safety results similar to placebo.
In May 2022, the Company presented a successful thorough QT analysis demonstrating ensifentrine had no clinically relevant effect on the QT interval or cardiac conduction at the American Thoracic Society International Conference ("ATS") 2022. The abstract is published on the ATS website and in the peer reviewed publication, American Journal of Respiratory and Critical Care Medicine.
In June 2022, the Company completed enrollment in ENHANCE-1 with more than 800 subjects randomized.

Second Quarter 2022 Financial Results

Cash position: Cash and cash equivalents at June 30, 2022, were $111.5 million (March 31, 2022: $132.8 million). The Company believes cash and cash equivalents at June 30, 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 $15.0 million for the second quarter ended June 30, 2022 (Q2 2021: $20.6 million). The decrease of $5.6 million was primarily due to a $4.2 million decrease in clinical trial and other development costs as we progressed to the later stages of our Phase 3 ENHANCE program and a $1.9 million decrease in share-based compensation.
SG&A Expenses: Selling general and administrative expenses ("SG&A") were $5.5 million for the second quarter ended June 30, 2022 (Q2 2021: $8.0 million). The decrease of $2.5 million was primarily due to a decrease in share-based compensation.
Net loss: Net loss was $17.8 million for the second quarter ended June 30, 2022 (Q2 2021: net loss $22.1 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. Ensifentrine met the primary endpoint in ENHANCE-2 demonstrating a statistically significant and clinically meaningful improvement in lung function. In addition, ensifentrine significantly reduced the rate of COPD exacerbations. 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 in an effort to ensure the safety of study participants, minimize risks to study integrity, and maintain compliance with good clinical practice.

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 ENHANCE-1 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 are impacting, and may continue to impact, the Company's outsourced clinical research vendor's ability to pay the clinical trial sites and investigators in Russia and may impact the vendor's ability to supply ensifentrine and equipment to the sites and validate their trial data. If the conflict extends into other countries in Europe where the Company's clinical trials are being conducted, its 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 its plans to submit an NDA for ensifentrine.
