Evaluation of the Glucoregulatory Effects of Glucagon-like Peptide-1 Receptor (GLP-1 Receptor) Activation in Participants With Type 2 Diabetes Mellitus (MK-0000-222)
September 1, 2015 updated by: Merck Sharp & Dohme LLC
Evaluation of the Glucoregulatory Effects of GLP-1 Receptor Activation in Patients With Type 2 Diabetes Mellitus
This was a four-period crossover study to assess the glycemic effects of a single dose of oxyntomodulin (OXM) on the glucose levels in participants with Type 2 diabetes mellitus (T2DM).
Participants were randomly assigned to 1 of 6 treatment sequences consisting of 4 treatment periods, with a 7-day wash-out between each treatment period.
The primary hypothesis was that during graded glucose infusion (GGI) oxyntomodulin (OXM) is neutral or better than placebo (Pbo) at lowering ambient plasma glucose levels, and at significantly enhancing insulin secretion.

Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Time-weighted Average of Glucose Measured by Area Under the Curve (AUC) After a Single Dose of Oxyntomodulin (OXM)
Time Frame: Baseline and during GGI at time points 0, 20, 40, 60, 80, 100, 120, 140, 160 and 165 minutes
|
Participants received on Day (-1) an overnight intravenous (IV) infusion of insulin titrated to achieve baseline fasting plasma glucose on Day 1 of between 90 and 130 mg/dL.
Participants also received on Day (-1) a single dose of liraglutide (Lg) or placebo for Lg, after which insulin infusion was discontinued.
Following overnight fast, participants received on Day 1 OXM or placebo for OXM, accompanied by up to 160 minutes of graded glucose infusion (GGI).
During GGI glucose (20% D/W) was gradually infused at rates of 2,4,6 and 10 mg/kg/min, with each rate lasting approximately 40 minutes.
Glucose levels were measured from blood collected at baseline and during GGI at the following minutes: 0, 20, 40, 60, 80, 100, 120, 140, 160 and 165 in order to calculate the time-weighted average change from baseline in glucose AUC from 0-160 minutes.

Baseline and during GGI at time points 0, 20, 40, 60, 80, 100, 120, 140, 160 and 165 minutes
|
Change From Baseline in Maximum Ambient Glucose Concentration (Gmax) After a Single Dose of OXM
Time Frame: Baseline and up to 160 minutes after start of GGI
|
Participants received on Day (-1) an overnight IV infusion of insulin titrated to achieve baseline fasting plasma glucose on Day 1 of between 90 and 130 mg/dL.
Participants also received on Day (-1) a single dose of Lg or placebo for Lg, after which insulin infusion was discontinued.
Following overnight fast, participants received on Day 1 OXM or placebo for OXM, accompanied by up to 160 minutes of GGI.
During GGI glucose (20% D/W) was gradually infused at rates of 2,4,6 and 10 mg/kg/min, with each rate lasting approximately 40 minutes.
Glucose levels were measured from blood collected at baseline and during GGI to determine the maximum ambient glucose concentration above baseline.

Baseline and up to 160 minutes after start of GGI
|
Change From Baseline in Beta Cell Sensitivity to Glucose (Φ) After a Single Dose of OXM
Time Frame: Baseline and up to160 minutes after start of GGI
|
Beta cell sensitivity measures the ability to mount an insulin secretory response relative to the level of ambient plasma glucose.
Participants received on Day (-1) an overnight IV infusion of insulin titrated to achieve baseline fasting plasma glucose on Day 1 of between 90 and 130 mg/dL.
Participants also received on Day (-1) a single dose of Lg or placebo for Lg, after which insulin infusion was discontinued.
Following overnight fast, participants received on Day 1 a single dose of OXM or placebo for OXM, accompanied by up to 160 minutes of GGI.
During GGI glucose (20% D/W) was gradually infused at rates of 2,4,6 and 10 mg/kg/min, with each rate lasting 40 minutes.
Glucose (G), insulin and C-peptide levels were measured from blood collected at baseline and during GGI, with the decay in C-peptide concentration used to indirectly estimate the Insulin Secretion Rate (ISR).
Beta Cell Sensitivity (Φ) was determined from the regression of the ISR on ambient plasma glucose (G).

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Insulinotrophic Effect (ISR/G) at the Highest Glucose Infusion Rate After Two Periods of Placebo Treatment
Time Frame: Baseline and 160 minutes after start of GGI at each placebo treatment period
|
The reproducibility of insulinotrophic effects was compared after two separate placebo treatment periods within the same treatment sequence.
Participants received on Day (-1) an overnight IV infusion of insulin titrated to achieve baseline fasting plasma glucose on Day 1 of between 90 and 130 mg/dL.
Participants also received on Day (-1) a single subcutaneous dose of placebo for Lg, after which insulin infusion was discontinued.
Following overnight fast, participants received on Day 1 placebo for OXM, accompanied by up to 160 minutes of GGI.
During GGI glucose (20% D/W) was gradually infused at rates of 2,4,6 and 10 mg/kg/min, with each rate lasting approximately 40 minutes.
Over these two treatment periods glucose (G), insulin and C-peptide levels were measured from blood collected at the highest glucose infusion rate; with the decay in C-peptide concentration used to indirectly estimate the Insulin Secretion Rate (ISR), and hence to determine the insulinotrophic effect, ISR/G.
