Effect of Gemigliptin on Metabolic Endotoxemia and Lipemia - Full Text View

Purpose

This is an exploratory study on the metabolic endotoxemia associated with type 2 diabetes. The investigators will measure systemic endotoxin level and lipid level after ingestion of high fat diet to evaluate the effect of gemigliptin, a DPP-4 inhibitor, on metabolic endotoxemia and lipemia induced by high fat diet.

Primary Outcome Measures:

Difference between baseline and peak serum LPS [ Time Frame: serum LPS before high fat diet and 15 min, 30 min, 1 hr, 2 hr, 3 hr, 4 hr after high fat diet ]
The increment of serum LPS after ingestion of high fat diet

Secondary Outcome Measures:

Fasting serum LPS level [ Time Frame: After 10 hrs of fasting ]
Compare fasting LPS level between treatment group
Incremental AUC of serum LPS during oral fat tolerance test [ Time Frame: serum LPS before high fat diet and 15 min, 30 min, 1 hr, 2 hr, 3 hr, 4 hr after high fat diet ]
Calculated incremental AUC of serum LPS
Difference between baseline and peak serum triglyceride level [ Time Frame: serum TG before high fat diet and 15 min, 30 min, 1 hr, 2 hr, 3 hr, 4 hr after high fat diet ]
The increment of serum TG after ingestion of high fat diet
Incremental AUC of serum triglyceride level during oral fat tolerance test [ Time Frame: serum TG before high fat diet and 15 min, 30 min, 1 hr, 2 hr, 3 hr, 4 hr after high fat diet ]
Calculated incremental AUC of serum TG
Difference between baseline and peak serum apolipoprotein-B48 [ Time Frame: serum apolipoprotein-B48 before high fat diet and 15 min, 30 min, 1 hr, 2 hr, 3 hr, 4 hr after high fat diet ]
The increment of serum apolipoprotein-B48 after ingestion of high fat diet
Incremental AUC of serum apolipoprotein-B48 during oral fat tolerance test [ Time Frame: serum apolipoprotein-B48 before high fat diet and 15 min, 30 min, 1 hr, 2 hr, 3 hr, 4 hr after high fat diet ]
Calculated incremental AUC of serum apolipoprotein-B48
Serum level of inflammatory markers (CRP, TNF-alpha, IL-6) [ Time Frame: After 10 hr of fasting ]
Compare serum level of inflammatory markers between treatment groups
mRNA expression level of inflammatory markers in the adipose tissue [ Time Frame: After high fat diet ingestion ]
Compare mRNA expression level of inflammatory markers

Study Completion Date:	July 2015
Primary Completion Date:	July 2015 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Gemigliptin Gemigliptin 50mg qd added to subjects current diabetes treatment	Drug: Gemigliptin Other Name: Zemiglo
Placebo Comparator: Placebo Placebo (identical in appearance to gemigliptin)	Drug: Placebo

Detailed Description:

Study subjects will be allocated to either gemigliptin or placebo. After 4 weeks of treatment and 2 weeks of wash out period, all subjects will be switched to the opposite arm.

The subjects will be tested oral fat tolerance test and adipose tissue needle biopsy(only for the subjects who agreed to participate donate adipose tissue) at 3 time points: the start of 1st treatment, end of 1st treatment and end of 2nd treatment.
