A Study to Compare the Pharmacokinetics of Budesonide Delivered by PT027 Compared With Pulmicort Flexhaler (ELBRUS)

Completed · Phase 1

Conditions studied: Relative Bioavailability

In brief

This study is to compare the systemic exposure of budesonide delivered by the combination inhaler (budesonide/albuterol sulfate pressurized inhalation suspension \[BDA metered dose inhaler {BDA MDI}\]) with Pulmicort Flexhaler dry-powder inhaler (DPI).

Who can join

Age: 18 and older, up to 55. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Provision of signed and dated, written informed consent prior to any study specific procedures.
• Healthy male and female participants aged 18 to 55 years with suitable veins for cannulation or repeated venipuncture.
• Females must have a negative pregnancy test at the Screening Visit and on admission to the Clinical Unit, must not be lactating.
• Have a body mass index (BMI) between 18 and 30 kg/m2 inclusive and weigh at least 50 kg and no more than 100 kg inclusive.
• Must be able to demonstrate proper inhalation technique using the Vitalograph Aerosol Inhalation Monitor (AIM) device 3 repeated times as well as be able to use the BDA MDI and Pulmicort Flexhaler devices according to instructions.
• Forced expiratory volume in 1 second in liters (FEV1) ≥80% of predicted value and FEV1/forced vital capacity in liters (FVC) ratio ≥70%.

You may not qualify if…

• Pregnant or nursing female participants or participants who are trying to conceive
• For female participants, a positive serum human chorionic gonadotropin (hCG) test at the Screening Visit or a positive urine hCG at admission for any of the 2 Treatment Periods.
• History of any clinically significant disease or disorder which, in the opinion of the PI, may either put the volunteer at risk because of participation in the study, or influence the results or the volunteer's ability to participate in the study.
• History or presence of gastrointestinal, hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
• Participants who have cancer that has not been in complete remission for at least 5 years.
• Any history of asthma or Chronic obstructive pulmonary disease (COPD).
• Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of IMP.
• Any clinically significant abnormalities in clinical chemistry, hematology, or urinalysis results at the Screening Visit, as judged by the PI.
• Any clinically significant abnormal findings in vital signs at the Screening Visit, as judged by the PI.
• Any clinically significant abnormalities on 12-lead electrocardiogram (ECG) at the Screening Visit, as judged by the PI.
• Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody, and human immunodeficiency virus (HIV) antibody.
• Known or suspected history of alcohol or drug abuse, or excessive intake of alcohol, in past 2 years, as judged by the PI.
• Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the first administration of IMP in this study. The period of exclusion begins 3 months after the final dose or one month after the last visit whichever is the longest.
• Plasma donation within 1 month of screening or any blood donation/loss more than 500 mL during the 3 months prior to the Screening Visit.
• History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the PI or history of hypersensitivity to drugs with a similar chemical structure or class to budesonide, albuterol sulfate and any component of the MDI and DPI.
• Current smokers or those who have smoked or used nicotine products (including e-cigarettes) within the 3 months prior to screening.
• Positive screen for drugs of abuse, cotinine or alcohol at the Screening Visit or on each admission to the Clinical Unit.
• Use of drugs with enzyme-inducing properties such as St John's Wort within 3 weeks prior to the first administration of IMP.
• Use of any prescribed or non-prescribed medication including antacids, analgesics (other than paracetamol/acetaminophen), herbal remedies, megadose vitamins (intake of 20 to 600 times the recommended daily dose) and minerals during the 2 weeks prior to the first administration of IMP or longer if the medication has a long half-life.
• Involvement of any AstraZeneca, PAREXEL or study site employee or their close relatives.
• Judgment by the PI that the participant should not participate in the study if they have any ongoing or recent (i.e., during the screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions, and requirements.
• Vulnerable participants, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
