Description of intervention(s) / exposure
This is a Phase I study to assess the safety and efficacy of DCB-DM101 add-on therapy in subjects with Type 2 Diabetes Mellitus who are inadequately controlled on Metformin and Sitagliptin or Metformin and Empagliflozin.

Evaluable Type 2 Diabetes Mellitus subjects will be recruited and allocated to one of the following three treatment arms whereby the add-on therapy will be once daily (taken in the morning) for 7 consecutive days in total:

Treatment Arm 1)
8 participants currently taking metformin (greater than or equal to 850 mg/day) + sitagliptin (greater than or equal to 100 mg/day) will add the study drug (DCB-DM101: 2x 165 mg tablets taken orally once per day) to their treatments.

Treatment Arm 2)
8 participants currently taking metformin (greater than or equal to 850 mg/day) + empagliflozin (greater than or equal to 10 mg/day) will add the study drug (DCB-DM101: 2x 165 mg tablets taken orally once per day) to their treatments.

Treatment Arm 3)
8 participants who are currently taking metformin (greater than or equal to 850 mg/day) + sitagliptin (greater than or equal to 100 mg/day) will add oral (tablet) empagliflozin (1x 10 mg tablet once per day) to their treatments.

Participants will record daily dosing in a participant dairy and all study drug dispensed will be returned at the end of the study. Study drug accountability will be monitored.

Comparator / control treatment
The comparator treatment in this study is Jardiance (empagliflozin),

Summary
Brief summary
Type 2 diabetes mellitus (T2DM) is a progressive multisystem disease. Despite the large amount of oral antidiabetic agents available, current therapy is not optimal. More than 60% of people with T2DM have inadequately controlled glucose levels.

DCB-DM101 is a new botanical investigational drug which has been developed by Development Centre for Biotechnology (DCB) in Taiwan. DCB-DM101 is hoped to offer an alternate approach to the management of many aspects of T2DM.

The aim of this Phase I study is to assess the safety and efficacy profile of DCB-DM101 (the "study drug") when given in combination with existing antidiabetic treatments (metformin and Januvia (sitagliptin) or metformin and Jardiance (empagliflozin)) to participants who have inadequately controlled T2DM. Two groups of participants will be recruited and take a daily oral dose of DCB-DM101 (330 mg/day) for 7 consecutive days in addition to their standard antidiabetic treatment (metformin and sitagliptin or metformin and empagliflozin). A third comparative group of participants will be administered empagliflozin (instead of DCB-DM101) in addition to their standard antidiabetic treatment of metformin and sitagliptin.
