Official TitleA Phase 1, Open-label, Single Cohort, Two-Period Fixed Sequence Study to Assess the Pharmacokinetics of Metformin Alone and in Combination With Ranolazine 500 mg Twice Daily in Subjects With Type 2 Diabetes Mellitus
Brief Summary
The purpose of this study is to evaluate the effect of steady-state ranolazine 500 mg bid on
the steady state pharmacokinetics (PK) of metformin in subjects with type 2 diabetes
mellitus (T2DM).
Detailed Description
The primary objective of this study is as follows:

• To evaluate the effect of steady-state ranolazine 500 mg twice daily (bid) on the steady
state pharmacokinetics (PK) of metformin in subjects with T2DM.

The secondary objectives of this study are as follows:

- To examine the safety and tolerability of metformin when co administered with
ranolazine 500 mg bid at steady-state in subjects with T2DM.

- To determine the steady-state PK of ranolazine 500 mg bid in subjects with T2DM
receiving metformin.
