Does Dapagliflozin Augment The Favorable Adaptation To Endurance Exercise Training?

19 mars 2019 uppdaterad av: Christopher Bell
Exercise is frequently prescribed as a favorable lifestyle intervention to prevent/reverse type 2 diabetes. It is also prescribed in addition to concurrent pharmacological treatment, such as metformin. Recent data (animal and human) suggest that metformin may attenuate the favorable benefits of exercise training. In light of the physiological mechanism of Dapagliflozin (sodium-glucose co-transporter 2 (SGLT2) inhibition), one might speculate that rather than inhibit, it will augment the favorable adaptations to exercise training.

Detaljerad beskrivning

This is a randomized, placebo-controlled, double blind, repeated measures study. 30 sedentary adults will be recruited for participation and randomly assigned to one of two 12-week treatments: 1) supervised endurance exercise training 4 days per week plus daily oral administration of Dapagliflozin; 2) supervised endurance exercise training 4 days per week plus daily oral administration of placebo. Prior to and following completion of the treatment the following dependent variables will be quantified: a) maximal aerobic capacity; b) substrate utilization during standardized low-moderate intensity exercise; c) skeletal muscle aerobic enzyme activity; d) body composition; and, e) oral glucose tolerance, fasting glucose and insulin resistance.

The dose of Dapagliflozin will begin as 5 mg/day for the first 14-days. In the absence of complications, side effects, or unfavorable reactions, the dose will then increase to 10 mg/day for the remainder of the study.

  4. Sedentary (maximum of 2/week regularly scheduled activity sessions of < 20 minutes during the previous 2 years).
  5. Completion of a screening visit consisting of medical history, physical examination, and 12-lead electrocardiogram and blood pressure assessment at rest and during incremental exercise to volitional exhaustion (Note: Subjects with abnormal screening values may be eligible if the results are not clinically significant, as judged by the investigator or medical monitor).
  6. Agree to abide by the study schedule and to return for the required assessments.
  7. Be willing and able to repeatedly perform exercise.
  8. Women of childbearing potential must have negative pregnancy test and be using acceptable contraception.

Exclusion Criteria:

Subjects should not enter the study if any of the following exclusion criteria are fulfilled:

  1. Evidence of clinically significant cardiovascular, respiratory, renal, hepatic, pulmonary, gastrointestinal, hematological, neurological, psychiatric, or other disease that may interfere with the objectives of the study or the safety of the subject, as judged by the investigator in agreement with the sponsor or medical monitor, have been hospitalized in the past 2 years as a result of these conditions, or are receiving pharmacological treatment for these conditions.
  2. Use of prescription drugs (see exceptions listed below) or herbal preparations in the 4 weeks before study commencement.

    Permitted Prescription Drugs

    • Birth Control
    • Less than 7 days, short course antibiotics. Note: Rifampin is not permitted.
    • Other medicines, for gastroesophageal reflux disease (GERD), depression, seasonal allergies and over-the-counter analgesics, may be allowed, but will be approved on a case-by-case basis.
  3. Is currently enrolled in another clinical study for another investigational drug or has taken any other investigational drug within 30 days before the screening visit.
  4. Habitual and/or recent use (within 2 years) of tobacco.
  5. Being considered unsuitable for participation in this trial for any reason, as judged by the investigator or medical monitor.
  6. History of serious hypersensitivity reaction to Dapagliflozin.
  7. Severe renal impairment, end-stage renal disease, or dialysis.
  8. Pregnant or breastfeeding patients.
  9. Severe hepatic insufficiency and/or significant abnormal liver function defined as aspartate aminotransferase (AST) >3x upper limit of normal and/or alanine aminotransferase (ALT) >3x upper limit of normal.
  10. Total bilirubin >2.0 mg/dL (34.2 umol/L).
  11. Positive serologic evidence of current infectious liver disease including Hepatitis B viral antibody Immunoglobulin M, Hepatitis B surface antigen and Hepatitis C virus antibody.
  12. Estimated Glomerular Filtration Rate <60 mL/min/1.73 m^2 (calculated by Cockcroft-Gault formula).
  13. History of bladder cancer.
  14. Recent cardiovascular events in a patient, including any of the following: acute coronary syndrome within 2 months prior to enrollment; hospitalization for unstable angina or acute myocardial infarction within 2 months prior to enrolment; acute stroke or trans-ischemic attack within two months prior to enrollment; less than two months post coronary artery re-vascularization; congestive heart failure defined as New York Heart Association class IV, unstable or acute congestive heart failure. Note: eligible patients with congestive heart failure,especially those who are on diuretic therapy, should have careful monitoring of their volume status throughout the study.
  15. Blood pressure at enrollment: Systolic blood pressure ≥165 mmHg and/or diastolic blood pressure ≥100 mmHg.
  16. Blood pressure at randomization: Systolic blood pressure ≥165 mmHg and/or diastolic blood pressure ≥100 mmHg

Change From Baseline of Insulin Sensitivity at Week 12
Tidsram: Baseline, 12 weeks
Insulin Sensitivity was estimated by measuring circulating glucose and insulin concentrations after a 12-hour fast and after ingestion of 75 g of glucose. Glucose was measured 5, 10, 15, 20, 30, 45, 60, 75, 90, 105 and 120 minutes after glucose ingestion. Insulin was measured 15, 30, 45, 60, 90 and 120 minutes after glucose ingestion. Insulin sensitivity was estimated using the Matsuda Index, represented by the formula: Matsuda index = 10,000/SQRT [fasting glucose*fasting insulin* (mean glucose from time 5, 10, 15, 20, 30, 45, 60, 75, 90, 105 and 120 minutes) * (mean insulin from time 15, 30, 45, 60, 90 and 120 minutes)], with higher numbers indicating better insulin sensitivity.
