The drug is a dual phosphodiesterase (PDE) 3 and 4 inhibitor and therefore has both bronchodilator and antiinflammatory effects, which are essential to the improvement of patients with COPD and asthma.

Seek and development Undertake pre-clinical and clinical development to the highest standard up to at least proof-of-concept in patients. Optimising value by focusing on “speed to market” Concentrate on drug candidates with a clear development path to commercialisation, high expected commercial value and the potential for wider use via novel formulations and new indications. Target patients with high unmet medical need to accelerate access to multi-billion dollar markets Initially target subsets of patients with high unmet medical need to increase the likelihood of obtaining an approvable, marketable and reimbursable drug. Potential to out-license Seek to partner broader indications with larger, later stage trial requirements and for commercialisation.

WHO expects COPD to be the third leading cause of disease globally by 2020. COPD is most commonly characterised by fixed airflow obstruction and chronic airways inflammation resulting from exposure to irritants like tobacco smoke. Across all COPD patients in the US, hospital admissions account for the majority (>50%) of direct health care costs. About Asthma Asthma, which remains one of the most common chronic diseases in the world, is characterised by recurrent breathing problems and symptoms such as breathlessness, wheezing, chest tightness, and coughing. In the U.S. asthma accounts for approx. 1.9 million annual emergency room visits and approx. 500,000 annual hospitalisations. The market for COPD and asthma drugs is currently estimated to be GBP20 billion. About Cystic Fibrosis Cystic fibrosis is an orphan disease with about 70,000 people afflicted worldwide. It is one of the most common life-threatening genetic conditions affecting humans. There is currently no cure and therefore significant demand for novel treatments.
