- Conditions
- Type 2 Diabetes Mellitus

- Brief Summary
This study evaluates the metabolomics changes associated with dapagliflozin treatment in patients with type 2 diabetes mellitus (T2DM). The participants in the study will be randomized to receive 10 mg dapagliflozin or placebo once daily for 12 weeks.
- Detailed Description
In this study, we hypothesize that metabolomics changes that occur in patients with T2DM after initiating SGLT2i (sodium-glucose cotransporter 2 inhibitors) treatment may be responsible for the beneficial cardiovascular and kidney effects observed in clinical trials with SGLT2i. Also, we propose that the study of the specific metabolome associated with the treatment with SGLT2i could help identify the possible metabolites and molecules that reduce CVD (cardiovascular disease) and renal disease in patients with T2DM.
The participants in the study will be randomized to receive 10 mg dapagliflozin or placebo once daily of for 12 weeks. Besides, all participants will be advised to engage in 150 min or more of moderate-to vigorous intensity physical activity per week, spread over at least 3 days/week, with no more than 2 consecutive days without activity and to engage in 2-3 sessions/week of resistance exercise on nonconsecutive days. Moreover, these patients will be advised to follow a lifestyle program that achieve a 500-750 kcal/day energy deficit or provide≈1,200-1,500 kcal/day for women and 1,500-1,800 kcal/day for men, adjusted for the individual's baseline body weight.

- 60
- Age 18-75.
- BMI 27-39.9 kg/m2.
- T2DM on treatment with metformin and inadequate metabolic control (defined as HbA1c≥6.5 -7%).
- Pregnancy (all women of child-bearing age, unless on treatment with contraceptive methods, will undergo a pregnancy test)
- Breastfeeding
- Intolerance/allergy to dapagliflozin.
- Treatment with antidiabetic drug other than metformin.
- Impaired kidney function: Estimated glomerular filtration rate (eGFR) <60 ml/min/1.73m2 (calculated using the CKD-EPI formula).
- Patients with established cardiovascular disease.
- Previous or current history of cancer of any kind.
- Uncontrolled hypertension (systolic blood pressure≥160 mmHg or diastolic blood pressure≥110 mmHg, despite adequate antihypertensive treatment).
- History of liver tumour or acute or chronic liver disease with impaired liver function: total bilirubin levels> 2.0 mg / dl or GOT/GPT levels three times higher than normal upper limit.
- Known HIV infection or active HBV or HCV infection.
- Other serious underlying diseases, which could affect the patient's ability to participate in the study.
- Reduced life expectancy (<12 months) due to advanced or terminal concomitant diseases.
In addition, female patients of child-bearing age will be advised to use contraceptive methods during the study period, given the contraindication of dapagliflozin and metformin during pregnancy as per normal clinical practice.

- Primary Outcome Measures
Name Time Method Metabolomics changes in blood From baseline to week 12 Targeted and quantitative analysis by ultra-high-resolution liquid chromatography coupled to triple quadrupole mass spectrometry (UHPL-QqQ/MS). Analysis of specific families of metabolites selected from hypotheses generated by previous exploratory studies: changes in acylcarnitines and other intermediates of mitochondrial β-oxidation and the urea cycle, branched-chain amino acids and biogenic amines
Metabolomics changes in urine From baseline to week 12 Targeted and quantitative analysis by ultra-high-resolution liquid chromatography coupled to triple quadrupole mass spectrometry (UHPL-QqQ/MS). Analysis of specific families of metabolites selected from hypotheses generated by previous exploratory studies: changes in acylcarnitines and other intermediates of mitochondrial β-oxidation and the urea cycle, branched-chain amino acids and biogenic amines
- Secondary Outcome Measures
Name Time Method BMI (body mass index) changes From baseline to to week 12 Measured by body composition analysis
Changes in insulin resistance From baseline to to week 12 Measured as HOMA-IR (homeostatic model assessment of insulin resistance)
Changes in Quality of Life: 36-Item Short Form Health Survey (SF-36) questionnaire From baseline to to week 12 The SF-36 has eight scaled scores: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health. The scores are weighted sums of the questions in each section. Scores range from 0 - 100, lower scores indicate more disability, and higher scores indicate less disability
Changes in albuminuria From baseline to to week 12 Modifications in albuminuria, measured as albumin excretion rate (AER)
Changes in metabolic control From baseline to to week 12 Measured as HbA1c (glycated hemoglobin)
