This trial is conducted in Europe. The aim of this trial is to investigate the effectiveness of Tresiba® (insulin degludec) after switching basal insulin in a population with type 1 or type 2 diabetes mellitus.
EU-TREAT (EUropean TREsiba AudiT)
Condition or disease | Intervention/treatment |
---|---|
Diabetes Diabetes Mellitus, Type 1 Diabetes Mellitus, Type 2 | Other: No treatment given |
Study Type : | Observational |
Actual Enrollment : | 2302 participants |
Observational Model: | Cohort |
Time Perspective: | Retrospective |
Official Title: | A European Multi-centre, Retrospective, Non-interventional Study of the Effectiveness of Tresiba® (Insulin Degludec) After Switching Basal Insulin in a Population With Type 1 or Type 2 Diabetes Mellitus |
Actual Study Start Date : | December 8, 2015 |
Actual Primary Completion Date : | August 12, 2016 |
Actual Study Completion Date : | August 12, 2016 |

Group/Cohort | Intervention/treatment |
---|---|
Tresiba® |
Other: No treatment given
Information will be collected from the medical records (paper/electronic) of each patient at several outpatient clinics to describe the two periods of medical history: before and after the initiation date of Tresiba®. For each patient, data will be collected, to describe a minimum of 6 months to a maximum of 12 months in each period; thus, the study will collect information on 12 to 24 months of medical history for each patient. |
