Study summary

The overall objective of this study was to assess the efficacy and safety of GP MDI relative to placebo in Japanese subjects with moderate to severe COPD. Each subject received the 4 separate study treatments, scheduled as four, 7-day, treatment periods for a total treatment duration of 28 days.

Read the detailed description

This was a randomized, double-blind, chronic-dosing (7-day), four-period, four-treatment, placebo-controlled, crossover, multi-center study to assess the efficacy and safety of 3 doses of GP MDI (28.8, 14.4, and 7.2 μg ex-actuator, BID) in Japanese subjects with moderate to severe COPD.

Subjects who met the entry criteria had their maintenance therapy for COPD adjusted, as specified in the protocol. To allow for an adequate washout of previous maintenance medications, subjects underwent a washout period of at least 7 days, but not greater than 28 days duration prior to returning to the clinic for Visit 2 (Randomization Visit; Day 1 of Treatment Period 1).

The 4 study treatments were GP MDI 28.8, 14.4, and 7.2 μg ex-actuator, and Placebo MDI BID. Subjects were randomly assigned to 1 of the following 4 treatment sequences (ABCD, BDAC, CADB, DCBA) in a 1:1:1:1 ratio using an Interactive Web Response System where each letter represented 1 of the 4 treatments included in the study by random assignment.

Subjects were to complete 7 days of dosing in each of the 4 Treatment Periods, with each Treatment Period separated by a washout period of 5 to 21 days.

  • Current and former smokers with a history of at least 10 pack-years of cigarette smoking.

-Post-bronchodilator must be ≥30% and \<80% predicted normal value-

Exclusion criteria

Exclusion Criteria:

  • Pregnancy
  • Primary asthma diagnosis; Poorly controlled defined as acute worsening of COPD that required treatment with or antibiotics in the 6-week interval prior to Screening or between Screening and Visit 2;
  • abnormal
  • Other active pulmonary disease such as active tuberculosis, lung cancer, bronchiectasis, sarcoidosis, lung fibrosis, primary pulmonary hypertension, interstitial lung disease, and uncontrolled sleep apnea; Cancer that was not in complete remission for at least 5 years;

Terms in these criteria, in plain language(5)

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.

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.

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.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

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 Jan 2015 to primary completion in Sep 2015, 7 months.

Results were first posted in Jan 2018, 2 years 4 months after primary completion.

Of 118 industry-sponsored phase 2 interventional studies under Pulmonary Disease, Chronic Obstructive, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 20. This study's 7 months is below that.

Counting every sponsor, half of 165 studies reached it within 17 months; a quarter within 10 and three quarters within 31.

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 Jan 23, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
