DOORS: A Research Study to Understand How Oral Semaglutide Works in People With Type 2 Diabetes Who Change From Dipeptidyl Peptidase-4 Inhibitor (DPP4i) Treatment to Oral Semaglutide in Italy (DOORS)
March 19, 2024 updated by: Novo Nordisk A/S
A Multicentre, Prospective, Non-Interventional, Single-Arm Study Investigating Glycaemic Control and Patient-Reported Outcomes in Type 2 Diabetes Patients, Uncontrolled on DPP4i Treatment and Who Switch to Oral Semaglutide in a Real-World Setting in Italy
The purpose of the study is to look at the change in blood sugar levels in people with type 2 diabetes who change their treatment from DPP4i to oral semaglutide.
Participant will get oral semaglutide as prescribed by the study doctor.
The study will last for about 5-6 months.
Participants will be asked to complete two questionnaires.
One will be about eating behaviour and the other one will be diabetes related.
Participant will complete this questionnaire during the normal scheduled visit with study doctor.
Participants will be asked questions about their health and diabetes treatment and lab tests as part of their normal doctor's appointment.

DEBQ is a 33-item self-reported questionnaire to assess three distinct eating behaviours in adults: emotional eating, external eating, and restrained eating.
For all 33 items participants will provide response in terms of: never, seldom, sometimes, often, very often.
Absolute change in DEBQ (total score) calculated as the absolute difference between the DEBQ scores (total score) at baseline and post baseline measurements of DEBQ scores (total score) up to and including end of study visit.

|
DDS is a self-administered 17-item scale that captures four critical dimensions of diabetes-related distress: emotional burden, regimen distress, interpersonal distress, and physician distress.
Each item was scored in the range of 1 to 6: 1) not a problem; 2) a slight problem; 3) a moderate problem; 4) somewhat serious problem; 5) a serious problem; 6) a very serious problem.
Participants will rate each item item indicating the degree to which each of the 17 items may have distressed or bothered them during the past month.
High score indicated high distress.
