The Effects of RPL554 on Top of Standard COPD Reliever Medications
- Conditions
- Chronic Obstructive Pulmonary Disease
- Interventions
- Drug: RPL554 matched placebo
- Registration Number
- NCT02542254
- Lead Sponsor
- Verona Pharma plc
- Brief Summary
This study evaluates the addition of RPL554 to standard reliever medications for chronic obstructive pulmonary disorder (COPD). All patients will receive the same six treatments in a randomised sequence:
1. salbutamol,
2. ipratropium,
3. salbutamol + RPL554,
4. ipratropium + RPL554,
5. RPL554
6. Placebo
- Detailed Description
The purpose of this study is to investigate if RPL554 has an additive bronchodilator effect when administered in combination with standard of care bronchodilators in patients with COPD.This study investigates the pharmacodynamic effect of RPL554 using spirometry and whole body plethysmography compared to placebo, when administered in addition to a beta2 agonist (salbutamol), a muscarinic antagonist (ipratropium) or placebo.
