Brief summary

This is a 12-week (with an extension to 52 weeks in a subset of participants) study comparing the safety of BGF MDI HFO twice daily (BID) with BGF MDI HFA BID in participants with moderate to very severe COPD.

Detailed description

This is a Phase 3 randomized, double-blind, 12-week (with an extension to 52 weeks in a subset of participants) study comparing the safety of BGF MDI HFO 320/14.4/9.6 μg twice daily (BID) with BGF MDI HFA 320/14.4/9.6 μg BID in participants with moderate to very severe COPD. For the 12-week study, 542 participants will be randomized to treatments BGF MDI HFO and BGF MDI HFA in a 1:1 ratio. Randomization will be stratified by region (Americas, Europe) and COPD disease severity (percent predicted FEV1 ≥ 50%, percent predicted FEV1 \< 50%). Subsequently, the 120 participants per treatment arm who were randomized to the extended study will continue and remain on the randomized treatment to 52 weeks.

Inclusion criteria

1. Participant must be 40 to 80 years of age inclusive, at the time of signing the ICF; 2. Participants who have a documented history of physician-diagnosed COPD as defined by the ATS/ERS (Celli et al 2004) or by locally applicable guidelines; 3. Participants who have been regularly using dual ICS/LABA, LAMA/LABA, or ICS/LAMA/LABA (open or fixed-dose combinations) inhaled maintenance therapies for the management of their COPD for at least 6 weeks prior to Screening; 4. Participants who have pre-bronchodilator FEV1 of \< 80% predicted normal at Visit 1; 5. Participants who have post-bronchodilator FEV1/FVC ratio of \< 0.70 and post-bronchodilator FEV1 of ≥ 25% to \< 80% predicted normal at Visit 2; 6. Participants who have CAT score ≥ 10 at Visit 1; 7. Participants who are current/former smokers with a history of at least 10 pack-years of tobacco smoking (1 pack year = 20 cigarettes smoked per day for 1 year); 8. Participants who are willing and, in the opinion of the Investigator, able to adjust current COPD therapy, as required by the protocol; 9. Participants must be able to demonstrate acceptable MDI administration and spirometry technique; 10. Participants who are willing to remain at the study center as required per protocol to complete all visit assessments; 11. Females must either be not of childbearing potential, or using a form of highly effective birth control as defined below: * 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 amenorrhoeic for 52 weeks (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 amenorrhoeic for 52 weeks (12 months) or more following cessation of exogenous hormonal treatment and follicle stimulating hormone levels in the postmenopausal range. * Women ≥ 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. 12. 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 * Women \<50 years of age with amenorrhea for 12 months without an alternative medical cause must have a serum LH and FSH test (within 21-28 days before Visit 3) for study eligibility Highly effective birth control methods are listed below: * Sexual abstinence defined as complete abstinence from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the participant * 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 * Male partner sterilization/vasectomy with documentation of azoospermia prior to the female participant's entry into the study, and this male is the sole partner for that participant. The documentation on male sterility can come from the site personnel's review of participant's medical records, medical examination and/or semen analysis or medical history interview provided by her or her partner. * Bilateral tubal ligation 13. Capable of giving signed informed consent as described in Appendix A which includes compliance with the requirements and restrictions listed in the ICF and in this protocol

Pre-assignment details

All participants randomized were enrolled in the 12-week study. Of these, 120 participants in each arm were assigned (on first-in-study basis) to continue in the extended 52-week study. This is why the number who Started the 52-week treatment period is less than the Protocol Enrollment number.
