Study objectives are as follows: Primary objectives: Quantify the frequency of off-label use of olodaterol among new users of these medications (i.e., the proportion of new users who do not have COPD) Describe the baseline characteristics of new users of olodaterol Secondary objective: Quantify the frequency of off-label use of indacaterol (a LABA approved for COPD but not for asthma) among new users of these medications (i.e., the proportion of new users who do not have COPD), in order to put into perspective the results for olodaterol initiators Describe the baseline characteristics of new users of indacaterol Country(-ies) of study: The Netherlands, Denmark, and Sweden Author: Marketing authorisation holder(s): MAH contact person: EU-QPPV: Signature of EU-QPPV: The signature of the EU-QPPV is provided electronically Boehringer Ingelheim Page 3 of 65 Protocol for observational studies based on existing data BI Study Number 1222.53 c02329987-02 Proprietary confidential information © 2014 Boehringer Ingelheim International GmbH or one or more of its affiliated companies 1.
