Study summary

DUS1 and DUS2 are descriptive drug utilisation studies in new users of aclidinium bromide in Europe.

The objectives of DUS1 and DUS2 are to describe the characteristics and patterns of use of new users of aclidinium bromide (monotherapy or in combination) and new users of other medications for chronic obstructive pulmonary disease (COPD); to evaluate the potential off-label use of aclidinium bromide; to describe users of aclidinium bromide in subgroups of patients for whom there is missing information in the risk management plan (RMP); and to establish a core cohort of new users of aclidinium bromide for the future evaluation of safety concerns described in the RMP.

The data source for these studies will be the CRPD in the UK, the GePaRD in Germany, and national health databases in Denmark.

Read the detailed description

DUS1 will be conducted when the target number of new users of aclidinium monotherapy is reached, and DUS2 when the target number of new users of aclidinium fixed-dose combination with formoterol is reached.

As this was a descriptive study no primary or secondary endpoints were specified.

Study population

New users of aclidinium bromide (on monotherapy or with concomitant use of formoterol) and new users of other COPD medications will be identified and included in the specific exposure cohort of interest.

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

  • Patients in the study will be required to meet the following criteria, as ascertained from each of the automated databases:
  • To have at least 1 year of enrolment in the database (DUS1 and DUS2).
  • To have not been prescribed aclidinium bromide as monotherapy or with concomitant use of formoterol during the 6 months before the date of first prescription of aclidinium bromide (index date) in DUS1
  • To have not been prescribed aclidinium bromide as monotherapy, with concomitant use of formoterol, or as aclidinium/formoterol during the 6 months before the date of first prescription of aclidinium bromide (index date) in DUS2

The same inclusion criteria will be applied for each of the comparator drugs.

Exclusion criteria

Exclusion Criteria:

  • No age restrictions or exclusion criteria will be applied. This will allow for the characterisation of all users of aclidinium bromide and comparator drugs irrespective of the indication for which these medications are used. Identification of potential off-label use of aclidinium bromide in the paediatric and adult populations is one of the specific objectives of this DUS.

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 Jul 2015 to primary completion in Feb 2017, 19 months.

Of 120 industry-sponsored observational studies under Pulmonary Disease, Chronic Obstructive, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 37. This study's 19 months is close to that.

Counting every sponsor, half of 587 studies reached it within 26 months; a quarter within 14 and three quarters within 58.

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 22, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
