Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study investigates the effect of 4 weeks of twice daily treatment of four different doses of RPL554 (a phosphodiesterase \[PDE\]3/4 inhibitor) or placebo in patients with moderate to severe chronic obstructive pulmonary disease (COPD). Patients will be equally allocated to one of the five treatment options.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

RPL554 is a dual inhibitor of PDE3 and PDE4 which are known to have a role in modulating the inflammatory airway response in respiratory diseases, including COPD. PDE3 inhibitors act as bronchodilators whilst PDE4 inhibitors have anti-inflammatory properties and there is also evidence to suggest that combined inhibition of PDE3 and PDE4 can have additive or synergistic anti-inflammatory and bronchodilator effects. PDE4 inhibitors (administered orally) have, however been associated with unfavorable gastrointestinal side effects such as nausea, emesis, diarrhea, abdominal pain, loss of appetite and weight loss. Dual PDE3/PDE4 inhibitors (administered by inhalation) have exhibited both bronchodilator and anti-inflammatory actions, with a more favorable side effect profile. It is plausible that increased efficacy with reduced side effects may be achievable with administration of a dual PDE3/4 inhibitor by the inhaled route compared to orally administered PDE3 or PDE4 inhibitors.

The purpose of this study is to investigate the dose response of RPL554 in patients with COPD over 4 weeks. This length of time should allow for study of the bronchodilator response, measured predominantly by the peak forced expiratory volume in one second (FEV1), and the anti-inflammatory response, as measured predominantly by trough FEV1.

* Chest X-ray (posterior-anterior) at screening, or chest X-ray, magnetic resonance imaging (MRI) or computed tomography (CT) scan in the last 12 months, showing no abnormalities which are both clinically significant and unrelated to COPD.
* Meet the concomitant medication restrictions and be expected to do so for the rest of the study.
* Current and former smokers with a smoking history of ≥10 pack years.
* Capable of withdrawing long acting bronchodilators until the end of the treatment period, and short acting bronchodilators for 8 hours prior to administration of study medication.

Exclusion Criteria

* A history of life-threatening COPD including Intensive Care Unit admission and requiring intubation.
* COPD exacerbation requiring oral steroids in the previous 3 months
* A history of one or more hospitalizations for COPD in the previous 6 months
* Lower respiratory tract infection treated with antibiotics in the previous 3 months

* Previous lung resection or lung reduction surgery.
* Oral therapies for COPD (e.g. oral steroids, theophylline, and roflumilast) in the previous 3 months and throughout the study.
* Pulmonary rehabilitation, unless such treatment has been stable from 4 weeks prior to Visit 1) and remains stable during the trial.
* A history of, or reason to believe a subject has, drug or alcohol abuse in the previous 3 years.
* Received an experimental drug within 30 days or five half-lives of the first dose
* Prior exposure to RPL554.

* Requirement for oxygen therapy, even on an occasional basis.
* Known hypersensitivity to RPL554 or its excipients/components.
* Abnormal clinically significant 12 lead Holter findings,
