Narrative objectives1 The objective is to compare the QOL outcomes in patients with type 2 diabetes following the use of either a DPP-4 inhibitor, linagliptin or metformin by using QOL questionnaires. The effects of linagliptin on blood biomarkers, such as HbA1c, are also examined for the treatment effects and safety.

Primary outcomes Change from baseline in OHA-Q score (total score) at the observation point of week 24
Key secondary outcomes The following outcomes from baseline to week 24 are evaluated:
1) OHA-Q, changed values of each domain score

2) Changed value of DTR-QOL (total score, each domain score)

3) Changed value of HbA1c

4) Prevalence of the patients (%) achieved the target HbA1c level (HbA1c< 6.0%, HbA1c< 7.0%, or HbA1c improved 0.5% or more)

5) Changed value of glucose level at fasting state

6) Prevalence of the patients (%) achieved HbA1c< 7.0% and improved their QOL scores

7) Incidence rate of hypoglycemia

8) Incidence rate of adverse events found in digestive system (diarrhea, nausea, vomiting)

9) Hospitalization (%) due to heart failure

10) Incidence rate of other adverse events

Type of intervention
Interventions/Control_1 Group A: Administer linagliptin
After randomization, patients in this group start linagliptin from 5 mg once a day for 24 weeks.
Interventions/Control_2 Group B: Administer metformin
After randomization, patients in this group start with metformin twice or three times per day of total 500 mg, and adjust the amount during the 24 week period, aiming for HbA1c below 7%.
