Clinical Trial Summary

The purpose of this study is to demonstrate that the lung function effect from orally inhaled BGF delivered via HFO propellant is equivalent to the lung function effect from orally inhaled BGF delivered via HFA propellant in participants with COPD. The study duration for each participant will be approximately 15 to 16 weeks and consist of: 1. A screening and placebo run-in period of approximately 2 weeks prior to first dosing 2. Three treatment periods of approximately 4 weeks each (one period for each of 3 study interventions) 3. A final safety follow-up visit via telephone contact approximately 1 to 2 weeks after the final dose administration Participants will be provided with rescue SABA (albuterol or salbutamol) to be used as needed throughout the study. Participants will attend in-clinic study visits approximately weekly during the screening/run-in period (Visits 1, 2, and 3), then every 4 weeks (Visits 4, 5, and 6) to receive take-home study treatment, measure their lung function, and assess their health and safety

Description:

This is a phase III, randomised, placebo-controlled, double-blind, multi-centre, 4-week, 3-way crossover pharmacodynamic study to assess the equivalence of BGF MDI HFO compared with BGF MDI HFA in participants with COPD. To demonstrate assay sensitivity, BGF MDI HFA will be compared to placebo MDI HFA for superiority in lung function, both pre- and post-dose. Eligible participants are between 40 and 80 years of age, inclusive, who have an established clinical history of COPD as defined by the ATS/ERS. Participants are required to have an FEV1/FVC ratio of < 0.70, have a post-bronchodilator FEV1 ≥ 40% and < 80% predicted normal value, have a blood eosinophil count < 300 cells/μL, and be current or former cigarette smokers with a history of at least 10 pack-years. Participants must not have had a COPD exacerbation treated with oral corticosteroids or antibiotics within 4 months prior to initiation of screening, and must not have had a COPD exacerbation that required hospitalisation within 12 months prior to initiation of screening. Eligible participants are those on treatment with LABA, LAMA, LAMA/LABA (open or fixed-dose combination), ICS/LABA (open or fixed-dose combination) inhaled maintenance therapies, or SABA, SAMA, or SAMA/SABA scheduled or as-needed inhaled therapies, or who are naïve to COPD therapy. This study will be conducted at approximately 95 sites globally. After screening, participants will be randomised 1:1:1:1:1:1 to receive study interventions in one of 6 possible treatment sequences.

Sex and Contraceptive/Barrier Requirements 10 Females must not be of childbearing potential or must use a form of highly effective birth control

as defined below:

• Females not of childbearing potential are defined as females who are either permanently sterilised (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy) or postmenopausal. Females will be considered postmenopausal if they have been amenorrhoeic for 52 weeks (12 months) prior to the planned date of randomisation without an alternative medical cause. The following age-specific

requirements apply:

• Females < 50 years old would be considered postmenopausal if they have been amenorrhoeic for 52 weeks (12 months) or more following cessation of exogenous hormonal treatment with FSH levels in the postmenopausal range.
• Females = 50 years old would be considered postmenopausal if they have been amenorrhoeic for 52 weeks (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. All FOCBP who are sexually active with a non-sterilised male partner must agree to use one highly effective method of birth control, as defined below, from enrolment throughout the study and until at least 14 days after the 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 [15:32] Lubian, Dominika amenorrhoea method are not acceptable methods of contraception. Female condom and male condom should not be used together.
• All FOCBP must have a negative serum pregnancy test result at Visit 1.
• Females < 50 years of age with amenorrhoea for at least 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 preferred and usual lifestyle of the participant (defined as refraining from heterosexual intercourse during the entire period of risk associated with the study interventions).
• Combined (oestrogen and progestogen-containing) hormonal contraception associated with inhibition of ovulation: o Oral o Intravaginal o Transdermal
• Progestogen-only hormonal contraception associated with inhibition of ovulation: o Oral o Injectable
• Implantable
