Brief Summary:

Specific Aim 1.To examine whether the combination of liraglutide plus canagliflozin can prevent the increase in Hepatic Glucose Production (HGP) following institution of canagliflozin therapy and produce an additive or even synergistic effect to lower the plasma glucose concentration and A1c.

Specific Aim 2: To examine whether combination therapy with liraglutide plus canagliflozin can produce an additive, or even synergistic, effect to promote weight loss and reduction in hepatic and visceral fat content.

Specific Aim 3. To examine whether combination therapy with liraglutide plus canagliflozin can produce an additive or even synergistic effect to reduce systolic/diastolic blood pressure and 24-hour integrated blood pressure.

Detailed Description:

Specific Aim 1.To examine whether the combination of liraglutide plus canagliflozin can prevent the increase in HGP following institution of canagliflozin therapy and produce an additive or even synergistic effect to lower the plasma glucose concentration and A1c. We will examine this hypothesis by comparing the effect of administration of liraglutide alone, canagliflozin alone, and the combination of liraglutide plus canagliflozin on:(i) the rate of HGP; (ii) decrease in fasting plasma glucose concentration; (iii) counter-regulatory hormone response and (iv) A1c. We anticipate that the addition of liraglutide to canagliflozin will prevent the increase in plasma glucagon concentration, augment insulin secretion, and blunt/block the increase in HGP in response to canagliflozin, resulting in a greater decrease in fasting plasma glucose concentration and A1c than observed with each therapy alone.

Specific Aim 2: To examine whether combination therapy with liraglutide plus canagliflozin can produce an additive, or even synergistic, effect to promote weight loss and reduction in hepatic and visceral fat content.

Specific Aim 3. To examine whether combination therapy with liraglutide plus canagliflozin can produce an additive or even synergistic effect to reduce systolic/diastolic blood pressure and 24-hour integrated blood pressure.

Arm Intervention/treatment
Active Comparator: Canagliflozin
canagliflozin (film-coated tablet), 100 mg/day, increased to 300 mg/day after week two if tolerated without side effects
Drug: Canagliflozin
Canagliflozin is a sodium-glucose co-transporter 2 (SGLT2) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus (1)
Other Name: Invokana

Active Comparator: liraglutide
liraglutide, 1.2 mg/day, increased to 1.8 mg/day after week two if tolerated without side effects
Drug: Liraglutide
Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.
Other Name: Victoza

Active Comparator: canagliflozin plus liraglutide
canagliflozin, 100 mg/day, plus liraglutide, 1.2 mg/day, increased to 300 mg/day and 1.8 mg/day, respectively at week two, if tolerated without side effects
Drug: Canagliflozin
Canagliflozin is a sodium-glucose co-transporter 2 (SGLT2) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus (1)
Other Name: Invokana

Drug: Liraglutide
Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.
Other Name: Victoza




Primary Outcome Measures :
  1. HbA1c at 4 Months [ Time Frame: Approximately 4 months ]
    Primary end point of the study is the HbA1c level in response to canagliflozin alone, liraglutide or canagliflozin with liraglutide.

  2. Fasting Plasma Glucose (FPG) at 4 Months [ Time Frame: Baseline to Approximately 4 months ]
    Values will be presented as the mean + (Standard Deviation) SD. The difference in HGP and all secondary endpoints at study end versus baseline will be calculated and compared between each active treatment group with ANOVA.


Secondary Outcome Measures :
  1. Body Mass Index (BMI) at 4 Months [ Time Frame: Approximately 4 months ]
    A measure of BMI at 4 months to examine effects of combination therapy with liraglutide plus canagliflozin.


Other Outcome Measures:
  1. Change in Matsuda Index of Insulin Sensitivity, Insulin Secretion, and Beta Cell Function During Oral Glucose Tolerance Test (OGTT) [ Time Frame: Change from Baseline to Approximately 4 months ]
    Values will be presented as the mean + SD. The Matsuda Index is a novel assessment of insulin sensitivity that is simple to calculate and provides a reasonable approximation of whole-body insulin sensitivity from the OGTT. The index is calculated from plasma glucose (mg/dl) and insulin (mIU/l) concentrations in both fasting state and post-OGTT. The index value obtained is compared to normal physiologic values to assess insulin sensitivity or resistance. The higher the number, the more insulin sensitive and the lower the number the more insulin resistant the subjects are. Insulin secretion will be measured from plasma C-peptide concentration during the OGTT and the Mari Model will be used to measure beta cell glucose sensitivity

  2. Change in Free Plasma Insulin at the End of the Study From Baseline Value [ Time Frame: At Approximately 4 months ]
    Values will be presented as the mean + SD. The difference in HGP and all secondary endpoints at study end versus baseline will be calculated and compared between each active treatment group with ANOVA.

  3. Change in Plasma Glucagon Concentration at the End of the Study Compared to Baseline [ Time Frame: Approximately 4 months ]
    Values will be presented as the mean + SD. The difference in HGP and all secondary endpoints at study end versus baseline will be calculated and compared between each active treatment group with ANOVA.

  4. Change in Total Body Weight at Study End Compared to Baseline [ Time Frame: Approximately 4 months ]
    Values will be presented as the mean + SD. The difference in HGP and all secondary endpoints at study end versus baseline will be calculated and compared between each active treatment group with ANOVA. The difference between baseline and study end will represent the change in body weight due to change in hepatic, visceral and abdominal subcutaneous fat.

  5. Change in 24-hour Blood Pressure at Study End Compared to Baseline. [ Time Frame: Approximately 4 months ]
    Values will be presented as the mean + SD. The difference in HGP and all secondary endpoints at study end versus baseline will be calculated and compared between each active treatment group with ANOVA.
