A Phase I, Single-Dose, Gamma Scintigraphy Study to Assess the Pulmonary Deposition of Technetium-99m Radiolabelled Budesonide, Glycopyrronium and Formoterol Fumarate MDI in Patients With Moderate to Severe/Very Severe COPD.

This study is a single treatment period, single dose gamma scintigraphy study investigating the deposition in the lungs of a Budesonide, Glycopyrronium and Formoterol Fumarate Metered Dose Inhaler (BGF-MDI). This study will be investigating how the drug (known as PT010) is distributed in the lungs of Chronic Obstructive Pulmonary Disease (COPD) patients (with moderate to very severe COPD) following a maximal 10 second breath hold. This inhaler is intended to be used in the treatment of COPD, which is a group of diseases which cause lung problems and difficulty breathing. PT010 is a new combination product of 3 marketed drugs called Glycopyrronium, Formoterol Fumarate and Budesonide.
