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.
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.
