A Phase 3 Study of BMS-477118 in Combination With Metformin in Subjects With Type 2 Diabetes Who Are Not Controlled With Diet and Exercise

Phase 3

Completed

• Conditions: Diabetes
• Interventions: Drug: Saxagliptin; Drug: Placebo; Drug: Metformin; Drug: pioglitazone

• Registration Number: NCT00327015
• Lead Sponsor: AstraZeneca

Brief Summary

The purpose of this trial is to understand if adding saxagliptin to metformin therapy is safe and works better than taking either saxagliptin or metformin alone

Detailed Description

All subjects will participate in a lead-in period, and qualifying subjects will continue into a short-term randomized treatment period. Subjects who complete the short-term period will be eligible to enter the long term extension period. Also, subjects in the short-term period who have an elevated blood sugar that requires additional medication for blood sugar control will be eligible to enter the long-term treatment extension period where they will receive pioglitazone (rescue medication) added onto their blinded study medication
