Completion of patient enrolment in
two RPL554 Phase IIa studies, ahead of expected
timeline
Headline data
expected in Q1 2016 and Q2 2016
5 November 2015, Cardiff –
Verona Pharma plc (AIM: VRP.L), the drug development company
focused on first-in-class medicines to treat respiratory diseases,
today announces it has completed patient enrolment for the Phase
IIa dose-finding study of RPL554 in asthma and the Phase IIa
combination study of RPL554 in chronic obstructive pulmonary
disease (COPD), in which the drug is being administered in addition
to standard of care bronchodilators. Headline data is
expected Q1 2016 for the asthma study and Q2 2016 for the COPD
combination study.
RPL554 is a novel inhaled PDE3/PDE4 inhibitor with
anti-inflammatory as well as bronchodilatory properties, currently
in development as a nebulised treatment for acute exacerbations in
COPD patients in a hospital or home-care setting. The
nebulised bronchodilator market was worth approximately
$1 billion in 2014 in the
US.1
As reported on 29 September 2015,
Phase IIa results from a prior study using nebulised RPL554 alone
in stable COPD patients with moderate severity of disease, showed
that, in addition to good tolerability and safety profile, RPL554
caused a pronounced improvement in lung function, as measured by
peak FEV1, suggesting the drug produced a clinically meaningful
bronchodilator effect.
Dr Jan-Anders Karlsson, the CEO
of Verona Pharma, said:
“We are very pleased to have
completed recruitment in both of these studies ahead of our plan.
We believe the results will continue to build on the positive data
recently announced from our Phase I/IIa study, which
demonstrated that the new commercially scalable, suspension
formulation of RPL554 is well tolerated and that the extent of the
bronchodilation exceeded that seen in earlier studies with the
prior formulation. We believe RPL554 has the potential to
become an important new treatment option for both COPD and asthma
patients and look forward to reporting headline data from both
studies in the first half of next year.”
About the studies
Phase IIa study of RPL554 asthma patients
In this study 29 patients with mild to moderate persistent
asthma will each receive single doses of nebulised RPL554, from the
very low dose to the highest dose previously tested in the Phase Ib
single ascending and multiple ascending dose (SAD and MAD) studies
of the same drug in healthy subjects. In this double-blind,
placebo-controlled, crossover study, each patient will also receive
two different doses of nebulised salbutamol, a commonly used
bronchodilator in these patients, and placebo. The primary
objective of the trial is to establish the dose-dependency of the
bronchodilator effect and the duration of action of RPL554 in
asthma patients. The study is being performed at Celerion
(Belfast, Ireland) and Skane
University Hospital (Lund,
Sweden).
Phase IIa combination study of RPL554 in COPD
patients
The primary objective of this study is to evaluate whether
RPL554 has an additive bronchodilator effect and is well tolerated
in COPD patients, when administered in addition to standard of care
bronchodilators. Thirty patients have been enrolled in this
double-blind, placebo-controlled, six way crossover study, which
will investigate the pharmacodynamic effect of nebulised RPL554 in
a commercially scalable suspension formulation. This trial
will use spirometry2 and whole body
plethysmography3 to compare RPL554 to placebo, when
administered with a beta2 agonist (salbutamol), and with a
muscarinic antagonist (ipratropium). The trial is being
performed at the Medicines Evaluation Unit in Manchester by lead
investigator Professor Dave
Singh.

Notes to Editors
About Verona Pharma plc
Verona Pharma plc is a UK-based clinical stage biopharmaceutical
company focused on the development of innovative prescription
medicines to treat respiratory diseases with significant unmet
medical needs, such as chronic obstructive pulmonary disease
(COPD), asthma and cystic fibrosis.
Verona Pharma's lead drug, RPL554, is a first-in-class drug
currently in Phase IIa trials as a nebulised treatment for acute
exacerbations of COPD in the hospital setting. The drug is a
dual phosphodiesterase (PDE) 3/4 inhibitor and therefore has both
bronchodilator and anti-inflammatory effects, which are essential
to the improvement of patients with COPD and asthma.
Verona Pharma is also building a broader portfolio of
RPL554-containing products to maximise its benefit to patients and
its value. This includes the very significant markets for
COPD and asthma maintenance therapy. The Company is also
exploring the potential of the drug in different diseases, such as
cystic fibrosis, where it is in pre-clinical testing and has
received a Venture and Innovation Award from the Cystic Fibrosis
Trust.
About Chronic Obstructive Pulmonary
Disease (COPD)
Sixty-five million people worldwide suffer from moderate to
severe COPD and the World Health Organisation (WHO) expects COPD to
be the third leading cause of death globally by 2020. It is
the only major chronic disease with increasing mortality.
Currently available drugs are aimed at long-term maintenance
therapy, with the market dominated by large pharma. Despite
the wide availability of these therapies, COPD patients suffer
acute periods of worsening symptoms (exacerbations), which cause,
in the US alone, some 1.5 million A&E visits, 726,000
hospitalisations and 120,000 deaths per annum.
