A Study to Investigate the Exposure of Budesonide, Glycopyrronium, and Formoterol (BGF) Delivered by Hydrofluoroolefin (HFO) Propellant Metered Dose Inhaler (MDI) Compared to a Hydrofluoroalkane (HFA) Propellant MDI in Healthy Adults

Phase 1

Active, not recruiting

• Conditions: Healthy Participants

• Registration Number: NCT06723756
• Lead Sponsor: AstraZeneca

Brief Summary

This study aims to assess the bioequivalence of the total systemic exposure and safety of budesonide, glycopyrronium, and formoterol (160/14.4/4.8 µg/actuation) when administered as BGF MDI HFO compared with BGF MDI HFA in healthy participants.

Detailed Description

This is a Phase I, randomized, double-blind, single-dose, single-site, three way cross-over study to assess the pharmacokinetic (PK) and safety of BGF MDI with HFO propellant compared with BGF MDI with HFA propellant in healthy participants (male or female).

The study will comprise of:

* A Screening period of up to 27 days;

* Three Treatment periods: Participants will receive a single dose of the study intervention on three separate occasions (Period 1, Period 2 and Period 3), with the final dose on Day 2 of Treatment Period 3, and a washout period of 5 to 7 days between administration of each dose;

* A final Safety Follow-up within 5 to 7 days after the last administration of the study intervention in Treatment Period 3.

Participants will receive all the treatments as a single dose (2 inhalations) (Treatment A \[BGF MDI HFO - test formulation\], and Treatment B \[BGF MDI HFA - reference formulation\]) in one of the 3 possible treatment sequences: ABB, BAB, or BBA. Each participant will be involved in the study for up to 52 days.

Recruitment & Eligibility

• Status: ACTIVE_NOT_RECRUITING
• Sex: All
• Target Recruitment: 105

Inclusion Criteria

• Healthy participants with suitable veins for cannulation or repeated venipuncture.
• All females must have a negative pregnancy test at the Screening Visit and on admission to the Clinical Unit.
• Females of childbearing potential must not be lactating and if heterosexually active must agree to use an approved method of highly effective contraception.
• Females of non-childbearing potential must be confirmed at the Screening Visit.
• Have a body mass index (BMI) between 18 and 30 kg/m2 inclusive and weigh at least 50 kg and no more than 120 kg inclusive.
• Participants must have a forced expiratory volume in the first second (FEV1) ≥ 80% of the predicted normal value (based on age, height, ethnicity and gender at birth) and an FEV1/forced vital capacity (FEV1/FVC) > 70% at the Screening Visit. FEV1/FVC can be reported as ratio ie, 0.7 or a percentage ie, 70%.

• Unresectable cancer that has not been in complete remission for at least 5 years.
• Any clinically significant abnormal findings in physical examination, clinical chemistry, hematology, urinalysis results, or vital signs at Screening.
• Any clinically significant abnormalities on 12-lead electrocardiogram (ECG) at Screening.
• Any positive result on Screening for serum hepatitis B surface antigen, hepatitis C antibody, or human immunodeficiency virus (HIV) antibodies.
• History of any respiratory disorders such as asthma, COPD, or idiopathic pulmonary fibrosis.
• History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity.
• Known or suspected history of alcohol or drug abuse as judged by the Investigator.
