Study of the QOL Evaluation of Trelagliptin in Patients With Type 2 Diabetes Mellitus
- Registration Number
- NCT03014479
- Lead Sponsor
- Takeda
- Brief Summary
The purpose of this study is to assess the reduction in treatment burden during 12 weeks of trelagliptin administration in patients with type 2 diabetes on diet and exercise therapy only.
- Detailed Description
The purpose of this study is to assess the reduction in treatment burden during 12 weeks of trelagliptin administration in patients with type 2 diabetes on diet and exercise therapy only. Eligible participants will be randomized to either the study drug (trelagliptin) group or the comparative drug (daily DPP-4 inhibitor) group. Treatment burden will be assessed using Diabetes Therapy Related -QOL (DTR-QOL) questionnaire and Diabetes Treatment Satisfaction Questionnaire (DTSQ).

- Primary Outcome Measures
Name Time Method Change From Baseline in Total Score for All Question Items in the Diabetes Therapy Related -QOL (DTR-QOL) Questionnaire at the End of Study Baseline (Week 0), up to the end of study (Week 12) DTR-QOL Questionnaire is a self-reported instrument assessing impact of diabetes treatment on health-related QOL. It includes 29 items across 4 subscales; Factor 1: Burden on social activities and daily activities (13 questions), Factor 2: Anxiety and dissatisfaction with treatment (8 questions), Factor 3: Hypoglycemia (4 questions) and Factor 4: Treatment satisfaction (4 questions). Each item is scored ranging from 1 to 7. Every score of the questions in Factor 1-3 and the score in Factor 4 converted into reverse (1-7 will be converted to 7-1) will be simply added up, and scores of each factor and the total figure will be subsequently converted from 0 to 100 (the best and worst scores will be equivalent to 100 and 0). Higher scores reflect better QOL and positive changes relative to baseline indicate improvement of QOL.
- Secondary Outcome Measures

Number of Participants Reporting One or More Treatment-emergent Adverse Events Up to 12 weeks An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A treatment-emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug.
