Aclidinium Bromide Post-Authorisation Safety Study to Evaluate the Risk of Cardiovascular Endpoints

Aclidinium Bromide Post-Authorisation Safety Study to Evaluate the Risk of Cardiovascular Endpoints: Common Study Protocol

The purpose of this study is to evaluate the potential cardiovascular safety concerns and all-cause mortality described in the risk management plan for aclidinium bromide, through sequential, nested case-control studies for each endpoint of interest

This is a post-authorisation safety study (PASS) of new users of aclidinium bromide, fixed dose aclidinium bromide/formoterol fumarate dihydrate, and other inhaled medications frequently used by patients with COPD

The plan is for the PASS study to be conducted on one population-based automated health database; the initial candidate database is the CRPD in the United Kingdom.

Inclusion Criteria:

1. Have at least 1 year of enrolment in the electronic database. In the CPRD, only patients with permanent registration status in "up to standard" participant general practices will be included in the cohort.
2. Be aged 40 years or older.
3. Have a recorded diagnosis of COPD.
4. Have not been prescribed a study medication of interest during the 6 months before the date of the first prescription for that specific study medication.

Exclusion Criteria:

1. Patients with cancer or other serious, non-cardiovascular, life-threatening conditions or indicators of severe comorbidity will be excluded from the study cohort.
2. Subjects who will be potentially excluded are those with the following conditions recorded in the database at any time before the date of cohort entry: cancer, HIV, respiratory failure, end-stage renal disease or dialysis, organ transplantation, drug or alcohol abuse, coma, congenital abnormalities of the heart or great arteries.
