About
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.
Full 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.

Inclusion criteria

- Male subject willing to wear a condom and whose partner of child bearing potential uses a highly effective method of contraception (e.g. partner use of intrauterine device (IUD)) or an effective method of contraception, i.e., established method of contraception + condom, if applicable (unless anatomically sterile or where abstaining from sexual intercourse is in line with the preferred and usual lifestyle of the subject) from first dose until 3 months after last dose of IMP;
- Subjects who have a body weight ≥50 kg at the Screening Visit and Subjects with a body mass index (BMI) of 18-30; BMI = body weight (kg) / [height (m)]2.
- Subject with no clinically significant history of previous allergy / sensitivity to Budesonide, Glycopyrronium and Formoterol Fumarate or any of the excipients contained within the IMP;
- Subject with no clinically significant abnormal serum biochemistry, haematology and urine examination values within 28 days before the first dose of IMP;
- Subject with a negative urinary drugs of abuse screen, determined within 28 days before the first dose of IMP (N.B. a positive alcohol result may be repeated at Investigator's discretion);
- Subject with negative human immunodeficiency virus (HIV) and hepatitis B surface antigen (Hep B) and hepatitis C virus antibody (Hep C) results;
- Subject with no clinically significant abnormalities in 12-lead electrocardiogram (ECG) determined within 28 days before first dose of IMP;
- Subject with no clinically significant abnormalities in vital signs (e.g., blood pressure/pulse, respiration rate, oral temperature) determined within 28 days before first dose of IMP (Supine BP <140/90 mmHg or resting HR<100 beats per minute);
- Subject must be available to complete the study (including all follow up contact);
- Subject must satisfy a medical examiner about their fitness to participate in the study;
- Subject must provide written informed consent to participate in the study.
Exclusion criteria
- Subjects with clinically significant neurologic, cardiovascular, hepatic, renal, endocrinologic, pulmonary, haematological, psychiatric, or other medical illness that would interfere with participation in this study;
- Subjects with a history of ECG abnormalities including PR>220 msec; QRS complex >120 msec; QT Corrected Using Fridericia's Formula (QTcF) >450 ms; or any significant morphological changes other than non-specific T wave changes;
- A history of additional risk factors for Torsades de Pointes (e.g., heart failure, family history of Long QT Syndrome);
- Subjects who have cancer that has not been in complete remission for at least 5 years;
- Subjects with a FEV1 < 80% of predicted value and/or a FEV1/FVC ratio < 0.7 at screening. Subjects must be able to perform reliable, reproducible pulmonary function test manoeuvres per American Thoracic Society / European Respiratory Society (ATS/ERS) guidelines;
- Subjects with symptomatic prostatic hypertrophy / prostrate resection within 6 months of screening / bladder neck obstruction or urinary retention that is clinically significant in the opinion of the Investigator;
- Subjects with a family history of glaucoma or a diagnosis of glaucoma;
- History of substance-related disorders (with the exception of caffeine-related and nicotine-related disorders) as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM), fourth edition, text revision within 1 year of Screening;
- History of smoking or the use of nicotine containing products or electronic cigarettes within 3 months of Screening by self-reporting;
- A positive alcohol or urine drug screen including cotinine for drugs of abuse at the Screening Visit or at the beginning of each treatment period;
- Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements within 28 days or 5 half-lives (whichever is longer) prior to the first dose of IMP, unless in the opinion of the Investigator and Sponsor's Responsible Physician the medication will not interfere with the study procedures or compromise subject safety. Paracetamol will be permitted at doses of ≤4 grams/day;
- Subjects with a history of an allergic reaction or hypersensitivity to the study drugs, or who develop allergic reaction or hypersensitivity to any component of the formulation(s) used in this study including 99mTc;
