Rpl554
Here's some info on it from the Veronapharma site. It's interesting that it will be a nasal inhalation medication.

Verona Pharma's lead drug, RPL554, is a "first-in-class" inhaled drug under development for chronic obstructive pulmonary disease (COPD), asthma and cystic fibrosis. The drug is an inhibitor of the phosphodiesterase 3 (PDE3) and phosphodiesterase 4 (PDE4) enzymes, two enzymes known to be of importance in the development and progression of immunological respiratory diseases. The drug has the potential to act as both a bronchodilator and an anti-inflammatory which would significantly differentiate it from existing drugs.
RPL554 was selected from a class of compounds co-invented by Sir David Jack, the former Director of Research at Glaxo who led the team that discovered many of the commercially successful drugs in the respiratory market.
Verona Pharma has successfully completed two double-blind placebo controlled randomised Phase 2b studies of RPL554: one in mild to moderate asthma and another in mild to moderate COPD. The drug was found to be well tolerated, free from drug-related adverse effects (especially cardiovascular and gastro-intestinal effects) and generated significant bronchodilation. Additionally, double-blind placebo controlled exploratory studies in healthy volunteers challenged with an inhaled irritant also generated consistent, clinically meaningful anti-inflammatory effects.
Verona Pharma is also carrying out exploratory studies to investigate the potential of RPL554 as a novel treatement for cystic fibrosis. In November 2014, the Company received a Venture and Innovation Award from the UK Cystic Fibrosis Trust to further such studies.
For further information on the potential of RPL554 for the treatment of respiratory diseases, refer to the peer-reviewed paper available on-line in the highly-respected medication journal, The Lancet Respiratory Medicine, entitled “Efficacy and safety of RPL554, a dual PDE3 and PDE4 inhibitor, in healthy volunteers and in patients with asthma or chronic obstructive pulmonary disease: findings from four clinical trials".
The competitive advantages of RPL554 include the following:
combining bronchodilator (PDE 3) and anti-inflammatory actions (PDE 4) in a single drug, something that is currently only achieved with a combination LABA and glucocorticosteroid inhaler,
unique in not using steroids or beta agonists, which have known side effects,
planned to be administered by nasal inhalation, thereby reducing the unwanted gastrointestinal side effects of many orally administered drugs.
History of Clinical Trials
Following completion in May 2008 of toxicological studies of RPL554, the Company commenced in February 2009 a Phase I/IIa clinical trial of the drug at the Centre for Human Drug Research (CHDR) at Leiden in the Netherlands. In September 2009, the Company announced that it had successfully completed the trial, demonstrating that RPL554 has a good safety profile and has beneficial effects in terms of bronchodilation and bronchoprotection in asthmatics and a reduction in the numbers of inflammatory cells in the nasal passages of allergic rhinitis patients.
In November 2010, the Company successfully completed a further trial that examined the safety and bronchodilator effectiveness of the drug administered at higher doses.
In August 2011, the Company demonstrated that bronchodilation is maintained over a period of 6 days with daily dosing of RPL554 in asthmatics.
In November 2011, the Company successfully demonstrated safety and bronchodilation of RPL554 in patients with mild to moderate forms of COPD.
In March 2013, the Company demonstrated positive airway anti-inflammatory activity with respect to COPD at a clinical trial carried out at the Medicines Evaluation Unit (MEU) in Manchester, UK.
