Relative Bioavailability of BI 44847 in Different Ethnic Groups and Evaluation of Effect of Diet and Acarbose Coadministration on Bioavailability Following Oral Administration of 200 mg BI 44847 in Healthy Male Volunteers
- Registration Number
- NCT02211950
- Lead Sponsor
- Boehringer Ingelheim
- Brief Summary
The objectives were to investigate the relative bioavailability of BI 44847 in different racial groups (white, Asian, and African subjects) and to investigate the effect of different types of diet and acarbose coadministration on the bioavailability of BI 44847 in white subjects.
