Phase 2
Completed
Conditions
Type 2 Diabetes Mellitus
Interventions
Registration Number
NCT02526524
Lead Sponsor
Elcelyx Therapeutics, Inc.
Brief Summary

The purpose of the study is to compare the glycemic effects of delayed-release metformin (Met DR) to placebo in subjects with type 2 diabetes mellitus (T2DM) over 16 weeks. The study is designed to evaluate several doses of Met DR (600 to 1500 mg once daily in the morning \[qAM\]) compared to placebo. A single-blind reference treatment of 2000 mg metformin immediate-release (Met IR) per day administered as equal divided doses (1000 mg Met IR BID) will also be included.
