About this study
Official title: A Phase I, Randomised, Two-Period, Single-Dose, Single-Centre, Crossover Gamma Scintigraphy Study to Assess the Pulmonary Deposition of Technetium-99m Radiolabelled Budesonide, Glycopyrronium and Formoterol Fumarate MDI, Following 3 s and 10 s Breath-Hold, in Healthy Male Subjects
This study is a 2 treatment period, single dose crossover, gamma scintigraphy study investigating the deposition in the lungs of a Budesonide, Glycopyrronium and Formoterol Fumarate Metered Dose Inhaler.
This study will be investigating how the drug (known as PT010) is distributed in the lungs following a 10 second or 3 second breath hold.
The study will involve the following visits: 1 screening visits, 2 treatment visits, each separated by around 7 days (each with 1 overnight stay; from the evening before dosing until a minimum of 4 hours post-dose on the morning of Day 1) and a post-study follow up phone call.
The study population will be 10 healthy males, aged between 28 and 50 years of age.
Read the detailed description
This study is a 2 treatment period, single dose crossover, gamma scintigraphy study investigating the deposition in the lungs of a Budesonide, Glycopyrronium and Formoterol Fumarate Metered Dose Inhaler.
This study will be investigating how the drug (known as PT010) is distributed in the lungs following a 10 second or 3 second breath hold.
This inhaler is intended to be used in the treatment of Chronic Obstructive Pulmonary Disease (COPD), which is a group of diseases which cause lung problems and difficulty breathing.
PT010 contains a combination of 3 marketed drugs called Glycopyrronium, Formoterol Fumarate and Budesonide.
Budesonide is a corticosteroid that works by preventing inflammation and thus can aid in respiratory diseases such as chronic obstructive pulmonary disease. Glycopyrronium \& Formoterol Fumarate are bronchodilators which act by relaxing the smooth muscle cells in the trachea and bronchi, allowing greater airflow into the lungs.
To enable us to determine how much of the drug gets into the lungs following different lengths of breath hold, a technique called gamma scintigraphy will be used. Gamma scintigraphy is a technique used to track the movement of a radiolabelled tracer inside the body.
By assessing the amount of PT010 in the lungs following different lengths of breath hold, it is intended that this information will provide guidance as to the most effective way of taking the inhaler.
The study will involve the following visits: 1 screening visits, 2 treatment visits, each separated by around 7 days (each with 1 overnight stay; from the evening before dosing until a minimum of 4 hours post-dose on the morning of Day 1) and a post-study follow up phone call.
The study population will be 10 healthy males, aged between 28 and 50 years of age.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing BGF MDI (budesonide, glycopyrronium and formoterol fumarate) with 10 s breath hold and BGF MDI ((budesonide, glycopyrronium and formoterol fumarate) with 3 s breath hold in people with Pulmonary Disease, Chronic Obstructive, run by AstraZeneca at 1 site in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage lung deposition following 10 s breath hold (time frame: Day 1 (of either Treatment Period 1 or 2)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Nov 2018.
