Verona Pharma Initiates Phase 3 Clinical Trials with Nebulized Ensifentrine for the Maintenance Trea

LONDON and RALEIGH, N.C., Sept. 23, 2020 (GLOBE NEWSWIRE) -- Verona Pharma plc (AIM: VRP) (Nasdaq: VRNA) (“Verona Pharma”), a clinical-stage biopharmaceutical company focused on respiratory diseases, announces the initiation of its ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) Phase 3 trials to evaluate the efficacy and safety of nebulized ensifentrine in patients with moderate to severe chronic obstructive pulmonary disease (“COPD”).

David Zaccardelli, Pharm. D., President and CEO of Verona Pharma, said: “We are excited to start our pivotal ENHANCE Phase 3 studies. If successful, the data will support the submission of a New Drug Application in the U.S. for nebulized ensifentrine for the maintenance treatment of COPD. This is an important milestone for Verona Pharma and we look forward to addressing the urgent need for a novel therapy for the treatment of COPD.”

Ensifentrine is a first-in-class product candidate that combines bronchodilator and anti-inflammatory activities in one compound. In prior clinical studies in COPD, ensifentrine has shown significant and clinically meaningful improvements in lung function, symptoms and quality of life as a monotherapy or added onto a maintenance bronchodilator. Ensifentrine has been well tolerated in clinical trials involving more than 1,300 subjects to date.

About the ENHANCE program

The two randomized, double-blind, placebo-controlled studies (ENHANCE-1 and ENHANCE-2) will evaluate the efficacy and safety of nebulized ensifentrine as monotherapy and added onto a single bronchodilator, either a LAMA (“long acting muscarinic antagonist”) or a LABA (“long acting beta-agonist”), compared to placebo. The two study designs will replicate measurements of efficacy and safety data over 24 weeks and ENHANCE-1 will also evaluate longer-term safety over 48 weeks.

  • Patient Population: Each study will enroll approximately 800 moderate to severe, symptomatic, COPD patients at sites primarily in the U.S. and Europe.

  • Dose/Duration: Patients will be randomized to receive a 3 mg nebulized dose of ensifentrine or nebulized placebo twice daily for 24 weeks in ENHANCE-2 or 48 weeks in ENHANCE-1.

  • Primary Endpoint: Improvement in lung function as measured by forced expiratory volume* in one second (“FEV1”) over 12 hours with ensifentrine after 12 weeks of treatment.

  • Key Secondary Endpoints: COPD symptoms and health-related quality of life through 24 weeks via the validated patient reported outcome tools, SGRQ and E-RS: COPD. Additional lung function endpoints including peak and morning trough FEV1 will also be assessed.

  • Safety: Assessed over 24 weeks in both studies and over 48 weeks in approximately 400 patients in ENHANCE-1.

Further information about this study can be found at www.clinicaltrials.gov, NCT04535986 (ENHANCE-1) and NCT04542057 (ENHANCE-2).

* FEV1: Forced Expiratory Volume in one second, a standard measure of lung function

About COPD

COPD is a progressive and life-threatening respiratory disease without a cure. It is the third leading cause of death globally, according to the World Health Organization. The condition damages the airways and the lungs, leading to debilitating breathlessness that has a devastating impact on performing basic daily activities such as getting out of bed, showering, eating and walking. U.S. sales of medicines used for chronic maintenance therapy of COPD were $9.6 billion in 2019. About 1.2 million U.S. COPD patients on dual/triple inhaled therapy, long-acting beta-agonist (“LABA”)/long-acting muscarinic antagonist (“LAMA”) +/- inhaled corticosteroid (“ICS”) remain uncontrolled, experiencing symptoms that impair quality of life. These patients urgently need better treatments.

About Ensifentrine

Ensifentrine (RPL554) is an investigational, first-in-class, inhaled, dual inhibitor of the enzymes phosphodiesterase 3 and 4 (“PDE3” and “PDE4”). This dual inhibition enables it to combine both bronchodilator and anti-inflammatory effects in one compound. Ensifentrine also activates the Cystic Fibrosis Transmembrane Conductance Regulator (“CFTR”), which is beneficial in reducing mucous viscosity and improving mucociliary clearance. Ensifentrine’s mechanism of action has the potential to alleviate respiratory symptoms such as breathlessness and cough and work against inflammation associated with COPD or inflammation triggered by viruses.

Ensifentrine has demonstrated significant and clinically meaningful improvements in both lung function and symptoms, including breathlessness, in Verona Pharma’s Phase 2 clinical studies in patients with moderate to severe Chronic Obstructive Pulmonary Disease (“COPD”). In addition, nebulized ensifentrine showed further improved lung function and reduced lung volumes in COPD patients taking standard short- and long-acting bronchodilator therapy, including maximum bronchodilator treatment with dual/triple therapy. Ensifentrine has been well tolerated in clinical trials involving more than 1,300 subjects to date.

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. The Company raised gross proceeds of $200 million through a private placement in July 2020 and expects the funds to support its operations and Phase 3 clinical program into 2023. Two additional formulations of ensifentrine are currently in Phase 2 development for the treatment of COPD: dry powder inhaler (“DPI”) and pressurized metered-dose inhaler (“pMDI”). Ensifentrine is in a pilot clinical study in patients hospitalized with COVID-19 and has potential applications in cystic fibrosis, asthma and other respiratory diseases.
