About

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.

Full 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.

Enrollment: 22,155 patients

Sex: All

Volunteers: No Healthy Volunteers

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

• 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.

Trial design

22,155 participants in 3 patient groups

Aclidinium bromide monotherapy

Description:

In DUS1, all new users of aclidinium either on monotherapy or with concomitant formoterol will be included. In addition, in DUS2, all new users of the fixed-dose combination of aclidinium/formoterol and any other new fixed-dose combinations of LAMAs and LABAs that become available during the study and that are captured in each database will be included.

Treatment:

Drug: Aclidinium bromide

Aclidinium bromide and formoterol

Description:

In DUS1, all new users of aclidinium either on monotherapy or with concomitant formoterol will be included. In addition, in DUS2, all new users of the fixed-dose combination of aclidinium/formoterol and any other new fixed-dose combinations of LAMAs and LABAs that become available during the study and that are captured in each database will be included.

Treatment:

Drug: Aclidinium bromide/formoterol

New users of other COPD medication

Description:

New users of other COPD medications (tiotropium, other LAMAs, LABA, LABA/ICS, LAMA/LABA), prescribed as recorded in the database.

Treatment:

Drug: Other COPD medication
