However, to date, no studies have investigated the direct switch from LABA/ICS to LAMA/LABA therapy—instead of switching to triple therapy—in a prospective, real-world, non-interventional setting.Methods: EVELUT® (NCT03954132) is an ongoing, prospective, open-label, multicenter, non-interventional study comparing the once-daily fixed-dose combination of tiotropium and olodaterol (tio/olo) versus any triple therapy (LAMA/LABA/ICS) in patients with COPD who are symptomatic despite LABA/ICS maintenance therapy. Patients with acute or frequent COPD exacerbations are excluded from the study. Participants will receive LABA/ICS maintenance treatment until Visit 1, followed by switching of treatment to tio/olo or LAMA/LABA/ICS. The primary endpoints are changes in modified Medical Research Council (mMRC) and COPD Assessment Test (CAT®) scores after approximately 12 weeks of treatment. Secondary endpoints are change in the patients’ general condition according to the Physician’s Global Evaluation score, the proportion of responders with a change in mMRC score of ≥ 1 and in CAT® score of ≥ 2, and patient satisfaction with the inhaler and therapy. The study is expected to enroll approximately 900 patients.Conclusion: EVELUT results are expected to add to the current real-world evidence informing therapeutic decisions for COPD in everyday clinical practice.Trial Registration: The European Union electronic Register of Post-authorisation Studies (EU PAS Register): EUPAS29784; the Federal Institute for Drugs and Medical Devices (BfArM): NIS Study No 7305; Clinicaltrials.gov: NCT03954132.Keywords: COPD, tiotropium/olodaterol, Spiolto® Respimat®, triple therapy, LAMA/LABA/ICS
