Study Details

Study Description

Brief Summary

The primary objectives of this study are to assess, in patients with Type 2 diabetes mellitus (DM) and presumed nonalcoholic fatty liver disease (NAFLD), the following:

  • The safety and tolerability of multiple doses of INT 747;

  • The effects of 2 dose levels (25 mg and 50 mg) of INT 747 on insulin resistance and glucose homeostasis;

  • Effects of INT-747 on hepatocellular function as measured by assessment of liver enzymes and biochemical markers of hepatic and metabolic function and inflammation, and;

  • Trough concentrations of INT-747 and its metabolites, glyco 6-ethyl chenodeoxycholic acid (6-EDCA) and tauro 6-ECDCA.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

This is a multi-center, double-blind, randomized, placebo-controlled, multiple-dose, parallel-group study. Three (3) cohorts of 12 patients each will receive either placebo, 25 mg INT-747, or 50 mg INT-747 by mouth daily for 6 weeks.

The primary objective of assessing changes in insulin resistance and glucose homeostasis will be attained by performing a euglycemic clamp procedure at baseline (Day 0) and at the end of 6 weeks of treatment (Day 43). Other endpoints will be evaluated by monitoring adverse experiences; vital signs; clinical laboratory values; plasma drug and metabolite concentrations; and general health and well-being.

Study Results

Participant Flow

Recruitment Details Sixty four subjects were enrolled in the study at 4 sites. Of the randomized subjects, 20 were randomized to INT-747 25 mg, 21 subjects to INT-747 50 mg, and 23 subjects to placebo. Study enrollment by center ranged from 4 to 31 subjects.
Pre-assignment Detail A protocol amendment allowed for the enrollment of 14 replacement subjects (to enroll up to 56 subjects meeting eligibility requirements). The amendment pre-specified that the original 14 subjects being replaced would not be included in the efficacy analysis since they did not meet the protocol requirements.

Statistical Analysis 1
Statistical Analysis Overview Comparison Group Selection 25 mg INT-747, Placebo
Comments The primary endpoints are calculated as the change (post minus pre treatment) during low dose and high dose insulin infusion periods. These are compared between placebo and INT-747 25 mg using t-tests for independent samples. These tests will be made without correction for multiple comparisons using 0.05 as the alpha criterion for significance. Results will be described with the corresponding means and standard deviations.
