Phase 4

Recruiting

• Conditions: Diabetes Mellitus, Type 2
• Interventions: Drug: Vildagliptin; Drug: Metformin; Drug: Imeglimin

• Registration Number: NCT05366868
• Lead Sponsor: National Center for Global Health and Medicine, Japan

Brief Summary

Study subjects will be randomly assigned to the three groups and receive the study drug for maximum of 156 weeks and undergo blood samplings and other diabetes mellitus-related tests.
