New inhaler for COPD patients put to the test in safety trial

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tested a new inhaler (BGF MDI HFO) delivering a triple-drug combination (budesonide, glycopyrronium, formoterol fumarate) against the current inhaler (BGF MDI HFA) in 559 people with moderate to very severe COPD. The main goal was to compare safety over 12 weeks, with some participants followed for up to a year. Researchers tracked serious and common side effects, especially breathing-related issues like cough or wheezing.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: budesonide, glycopyrronium, and formoterol fumarate (BGF)
What this could lead to: If successful, this could show that a new inhaler delivering BGF is as safe as the current one, offering an alternative for COPD patients.
What could go wrong: This is a safety-focused trial, not designed to prove better symptom control. The new inhaler may not be safer or could have unexpected side effects.

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 Exclusion Criteria: 1.

Participants who have COPD due to α1-Antitrypsin Deficiency; 3. Participants with historical or current evidence of a clinically significant disease including, but not limited to: cardiovascular, hepatic, renal, hematological, neurological, endocrine, gastrointestinal, or pulmonary.

Any clinically relevant abnormal findings in physical examination, clinical chemistry, hematology, vital signs, or ECG, which in the opinion of the Investigator, may put the participant at risk because of his/her participation in the study; Note: Participants with ECG QTcF interval (corrected for heart rate using Fridericia's formula \[QTcF\]) \> 480 msec will be excluded. Participants with high degree atrioventricular block II or III, or with sinus node dysfunction with clinically significant pauses who are not treated with pacemaker will also be excluded. 24.
