Participants are eligible to be included in the study only if all of the following criteria apply:
Capable of giving signed informed consent as described in the protocol which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
Healthy non-smoking male and/or female participants aged 18 to 60 years inclusive at the time of signing the informed consent, without respiratory comorbidities.
Participant must have a forced expiratory volume in 1 second (FEV1) ≥ 80% of the predicted value for age, height, and ethnicity at screening, and FEV1/forced vital capacity (FVC) ratio of > 70%.
Participant must demonstrate acceptable MDI administration using empty training MDI.
Participant willing to comply with study IP administration requirements, defined as ≥ 80% participant medication adherence during the Treatment Periods.
Body mass index (BMI) within the range 18 to 35 kg/m2 (inclusive), and weight within the range 50 to 120 kg (inclusive).
Female participants must be not of childbearing potential or must use a form of highly effective birth control as defined below:
(a) Women not of childbearing potential are defined as women who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Women will be considered postmenopausal if they have been amenorrheic for 12 months prior to the planned date of randomization without an alternative medical cause. The following age-specific requirements apply:
Women < 50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment and follicle stimulating hormone (FSH) levels in the postmenopausal range.
Women ≥ 50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatment.
Female participants of childbearing potential must use one highly effective form of birth control. A highly effective method of contraception is defined as one that can achieve a failure rate of less than 1% per year when used consistently and correctly. At enrollment, women of childbearing potential who are sexually active with a non-sterilized male partner should be stable on their chosen method of highly effective birth control, as defined below, and willing to remain on the birth control until at least 14 days after last dose of study intervention. Cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhea method are not acceptable methods of contraception. Female condom and male condom should not be used together.
All women of childbearing potential must have a negative serum pregnancy test result at Visit 1.
Females <50 years of age with amenorrhea for 12 months without an alternative medical cause must have a serum FSH test at Visit 1.
Highly effective birth control methods are listed below:
Total sexual abstinence is an acceptable method provided it is the usual lifestyle of the participant (defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments).
Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation:
Oral
Intravaginal
Transdermal
Progestogen-only hormonal contraception associated with inhibition of ovulation:
Oral
Injectable
Implantable
Intrauterine device or intrauterine hormone-releasing system

You may not qualify if…

Participants are excluded from the study if any of the following criteria apply:
History of smoking > 10 pack-years, or participant quit smoking < 6 months prior to screening.
Acute or chronic upper or lower respiratory illness within 30 days of screening.
Respiratory medication or medication impacting ciliary clearance for any indication within 30 days of screening.
History of more than 2 chest CTs or equivalent (> 10 mSv) within the past year.
History of any clinically significant disease or disorder which, in the opinion of the investigator, may either put the participant at risk because of participation in the study, or influence the results or the participant's ability to participate in the study.
Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of the IP.
History of any cancer except squamous cell and basal cell carcinomas of the skin.
Any clinically significant abnormalities in clinical chemistry, hematology, or urinalysis results, at screening as judged by the investigator.
Any clinically significant abnormal findings in vital signs at screening, as judged by the investigator.
Any clinically significant abnormalities on 12-lead ECG at screening, as judged by the investigator. Note: Participants with ECG QT interval corrected for heart rate using Fridericia's formula (QTcF) > 480 msec will be excluded.
A SARS-CoV-2 infection in the 8 weeks prior to Visit 1, or during the Screening Period, or that required hospitalization at any time prior to Visit 1 or during the Screening Period.
Participant has clinical signs and symptoms consistent with SARS-CoV-2 infection; eg, fever, dry cough, dyspnea, sore throat, fatigue, or laboratory-confirmed acute infection with SARS-CoV-2.
Participant who had severe course of COVID-19 (extracorporeal membrane oxygenation, mechanically ventilated, Intensive Care Unit stay).
History of any respiratory disorders such as asthma, chronic obstructive pulmonary disease, or idiopathic pulmonary fibrosis, alpha-1 antitrypsin, primary ciliary dyskinesia, cystic fibrosis.
Known or suspected history of drug abuse, as judged by the investigator.
Current smokers or those who have smoked or used nicotine products (including electronic cigarettes) marijuana, vaping, etc, within the 6 months prior to screening.
Positive screen for drugs of abuse or cotinine at screening.
Use of any prescribed or non-prescribed medication including antacids, analgesics (other than paracetamol/acetaminophen), herbal remedies, megadose of vitamins (intake of 20 to 600 times the recommended daily dose), and minerals within 14 days or 5 half-lives (whichever is longer) prior to the first administration of IP.
Excessive intake of caffeine-containing drinks or food (eg, coffee, tea, chocolate) as judged by the investigator. Excessive intake of caffeine defined as the regular consumption of more than 600 mg of caffeine per day (eg, > 5 cups of coffee) or would likely be unable to refrain from the use of caffeine-containing beverages.
Using any herbal products either by inhalation or by nebulizer within 2 weeks of Visit 1, and does not agree to stop for the duration of the study.
Participation in another clinical study with an IP administered in the last 30 days or 5 half-lives, whichever is longer.
Involvement of any AstraZeneca, Fortrea, or study site employee or their close relatives.
Participants who have previously received HFO via inhalation (eg, BGF [also known as PT010, Breztri, Trixeo] HFO).
Judgment by the investigator that the participant should not participate in the study if they have any ongoing or recent (ie, 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.
