Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Non-child bearing potential (ie, physiologically incapable of becoming pregnant, including any female who is 2 years ); or Child bearing potential, has a negative serum pregnancy test at Visit 1, and agrees to acceptable methods used consistently and correctly for the duration of the study.
  • Subjects with an established clinical history of as defined by the American Thoracic Society (ATS)/European Respiratory Society (ERS),
  • Current or former smokers with a history of at least 10 pack-years of cigarette smoking.
  • (FEV1)/Forced vital capacity (FVC) ratio must be \<0.70 and FEV1 must be \<65% predicted normal value calculated using NHANES III reference equations (or reference norms applicable to other regions).
  • Subjects with history of exacerbations.

Please refer to the study protocol for the complete inclusion criteria list.

Exclusion criteria

Exclusion Criteria

  • Significant diseases or conditions other than , which, in the opinion of the Investigator, may put the subject at risk because of participation in the study or may influence either the results of the study or the subject's ability to participate in the study.
  • Women who are pregnant or lactating, or are planning to become pregnant during the course of the study, or women of who are not using an acceptable method of .
  • Subjects, who in the opinion of the Investigator, have a current diagnosis of asthma.
  • Subjects who have been hospitalized due to poorly controlled COPD within 3 months prior to Visit 1 (Screening)
  • Subjects who have poorly controlled COPD, defined as acute worsening of COPD that requires treatment with oral or antibiotics within 6 weeks prior to Visit 1 (Screening)
  • Immune suppression or severe neurological disorders affecting control of the upper airway or other risk factors that in the opinion of the Investigator would put the subject at substantial risk of pneumonia.
  • Subjects with a diagnosis of narrow angle glaucoma, who, in the opinion of the Investigator, have not been adequately treated.
  • Subjects who have a history of to β2-agonists, budesonide or any other corticosteroid components, glycopyrronium or other muscarinic anticholinergics, or any other component of the IMPs.

Please refer to the study protocol for the complete inclusion criteria list.

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2015 to primary completion in Jul 2019, 48 months.

Results were first posted in Feb 2021, 1 year 6 months after primary completion. A results delay was requested in May 2020.

Of 108 industry-sponsored phase 3 interventional studies under Pulmonary Disease, Chronic Obstructive, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 36. This study's 48 months is above that.

Counting every sponsor, half of 141 studies reached it within 23 months; a quarter within 14 and three quarters within 44.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 2, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
