Brief Summary

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

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.

Detailed Description

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

This will be a single-dose study to assess the pulmonary deposition of Radiolabelled BGF MDI following administration in male and female patients with moderate to severe/very severe COPD. Serious Adverse Events (SAEs) will be recorded from the time of signing of informed consent form to Post-study Follow-up phone call. Non-serious Adverse Events (AEs) will be collected from the first dose on Day 1 to Post-study Follow-up phone call. Study drug will be administered by inhalation.

The study will comprise of a Screening Visit, followed by a single Treatment Period and a Post-study Follow-up phone call. The Treatment Period will be from the afternoon before (Day 1) until 4 hours (h) post dose (Day 1). Patients will arrive at the Clinical Unit on Day 1. Patients will withhold their regular COPD medication in the morning of Day 1 and instead be given short-acting Ventolin Hydrofluoroalkane (HFA) and Atrovent HFA which may be used up to (but not within) 6 h prior to dosing. Investigational Product (IP) will be administered on the afternoon of Day 1 fasted (after a fast of at least 2 h) and patients will be discharged 4 h post dose (Day 1), provided there are no ongoing safety concerns. During the treatment period, patients will also undergo a Krypton-81m (81mKr) gas ventilation imaging scan and a Cobalt-57 (57Co) transmission scan. SAEs will be evaluated from the time of signing the informed consent form and up to the Post-study Follow-up phone call, non-serious AEs will be evaluated from Day 1 following IP dose and up to the Post-study Follow-up phone call. Approximately 20 patients (10 per cohort) will be enrolled for at least 16 to complete the study:

* Approximately 10 patients with moderate COPD (Forced Expiratory Volume in 1 Second (FEV1) ≥50-\<80% of predicted normal), for at least 8 completed patients.
* Approximately 10 patients with severe/very severe COPD (FEV1 \<50% of predicted normal), for at least 8 completed patients.

At the time of dosing, patients will be required to perform 2 inhalations (after priming) under the supervision of an Investigator. Immediately following each inhalation, patients will perform a maximal breath-hold, up to 10 s, prior to exhaling into an exhalation filter. Once the second breath hold and exhalation has been performed, patients will rinse their mouth with water and expel the washings for collection. Patients will then swallow bread and water.

Thereafter, posterior and anterior views of the lungs and stomach, and a lateral head and neck view will be recorded using a gamma camera. All images will be of a maximum of 200 s in duration. Images will also be acquired of the exhalation filter and collected mouth washings. Mass balance calculations will be undertaken to determine the fraction of the emitted dose delivered to the lungs of the patients. The distribution pattern of radiolabel within the lungs will be described in terms of a ratio of radioactive counts in different lung regions, after accounting for differences in regional lung volumes.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Males and females at least 40 years of age and no older than 80 years.
* Patients with diagnosis of COPD as defined by the American Thoracic Society (ATS)/European Respiratory Society (ERS) \[1\].

* Post bronchodilator (BD) FEV1 / Forced Vital Capacity (FVC) ratio must be \< 0.70.
* Post BD FEV1 must be \< 80% predicted.

Other Respiratory Disorders: known active tuberculosis, lung cancer, cystic fibrosis, significant bronchiectasis (high resolution computerised tomography \[CT\] evidence of bronchiectasis that causes repeated acute exacerbations), immune deficiency disorders, severe neurological disorders affecting control of the upper airway, sarcoidosis, idiopathic interstitial pulmonary fibrosis, primary pulmonary hypertension, or pulmonary thromboembolic disease. Note: allergic rhinitis is not exclusionary.
