Your goal is to extract structured information from the user's input that matches the form described below. When extracting information please make sure it matches the type information exactly. Do not add any attributes that do not appear in the schema shown below.

```TypeScript

 { // Information on the clinical trial characteristics from the abstract
 conditions: string // The condition or disease being treated in the clinical trial
 drug_or_intervention: string // The drug or intervention used in the clinical trial
}
```


Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them. All output must be in JSON format and follow the schema specified above. Wrap the JSON in <json> tags.



Input:Efficacy and safety of saxagliptin added to metformin in Asian people with type 2 diabetes mellitus: a randomized controlled trial.  To assess efficacy and safety of saxagliptin added to metformin versus placebo plus metformin in Asian patients with type 2 diabetes mellitus (T2DM) and inadequate glycemic control on metformin alone. Adults (HbA(1c) 7.0-10.0%, on stable metformin ≥ 1500 mg/day) were randomized 1:1 to saxagliptin 5mg daily plus metformin (n = 283) or placebo plus metformin (n = 287). The primary end point was HbA(1c) change from baseline to Week 24. Saxagliptin plus metformin provided significant adjusted mean decreases versus placebo plus metformin (p ≤ 0.0052) in HbA(1c) (-0.78% versus -0.37%), fasting plasma glucose (-1.14 mmol/L versus -0.58 mmol/L), and postprandial glucose area under the curve from 0 to 180 min (-315 mmol min/L versus -160 mmol min/L). Significantly more saxagliptin-treated patients achieved a therapeutic glycemic response (HbA(1c)<7.0%) (46.5% versus 30.5%; p = 0.0001). The proportion of patients experiencing adverse events (excluding hypoglycemia) was similar for saxagliptin plus metformin (42.8%) versus placebo plus metformin (40.8%). Hypoglycemic events were reported in 1.4% of patients in each group. Saxagliptin added to metformin significantly improved glycemic control and was well tolerated in Asian patients with T2DM who had inadequate glycemic control with metformin and diet and lifestyle modification.
