NCT02871882

Brief Summary

To study the effect of an ileocolonic formulation of ox bile extract on insulin sensitivity, postprandial glycemia and incretin levels, gastric emptying, body weight and fasting serum FGF-19 (fibroblast growth factor) levels in overweight or obese type 2 diabetic subjects on therapy with DPP4 (dipeptidyl peptidase-4) inhibitors (e.g. sitagliptin) alone or in combination with metformin.

Outcome Measures

Primary Outcomes (1)

  • Change in Postprandial Glucose

    Measurement of the glucose concentration in the bloodstream 6 hours after eating a meal

    baseline to 1 month

Study Arms (2)

Ox bile extract

ACTIVE COMPARATOR

Ox bile extract 500 mg tablets taken orally twice daily for 28 (+/- 4) days Gastric Emptying test, Waist and hip measurements, Mixed oral glucose tolerance test, Blood tests

Radiation: Gastric Emptying testOther: Mixed Oral Glucose Tolerance testDrug: Conjugated bile acids sodium

Placebo

PLACEBO COMPARATOR

Matching placebo tablets taken orally twice daily for 28 (+/- 4) days Gastric Emptying test, Waist and hip measurements, Mixed oral glucose tolerance test, Blood tests

Radiation: Gastric Emptying testOther: Mixed Oral Glucose Tolerance testOther: Placebo

Interventions

participants eat a standardized meal labeled with radioactive markers (99mTc DTPA \[diethylenetriaminepentaacetic acid\] and In111 Chloride). They have scans taken at specific times after the meal to document the rate of gastric emptying.

Ox bile extractPlacebo

Participants eat a meal containing 63g glucose in 240mL (milliliters) of skim milk, 2 scrambled eggs, 50g Canadian bacon and one slice of bread. Blood samples are taken prior to and for 6 hours after the meal at specific time points.
