Brief Summary:
This trial will assess the efficacy of CRx-401 in lowering FPG levels in patients taking metformin to treat their diabetes. In addition, this initial trial will evaluate insulin resistance (HOMA-IR index), HgbA1c levels, glycated protein, LDL, HDL, triglycerides, and total cholesterol, as well as the safety of CRx-401.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 150 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized, Multi-Center Study to Compare the Effects of CRx-401 to Bezafibrate Plus Placebo on Plasma Glucose Levels When Given to Subjects With Type II Diabetes on Metformin.

Primary Outcome Measures :
  1. The primary efficacy endpoint will measure change in fasting plasma glucose from Baseline to Day 90 [ Time Frame: Day 90 ]

Secondary Outcome Measures :
  1. The exploratory efficacy endpoints will measure change in the following parameters: HOMA Index, HgbA1C, fructosamine, LDL, HDL, OGTT, triglycerides and total cholesterol from Baseline to Day 90 [ Time Frame: Day 90 ]
