Bioavailability of 3 Different Formulations of BI 207127 in Healthy Male Volunteers

Relative Bioavailability of BI 207127 FF Tablets, BI 207127 FF Modified Tablets and BI 207127 TFII Tablets Administered Orally as Three Tablets (Single Dose) to Healthy Male Volunteers, an Open-label, Randomised Three-way Crossover Study

The primary objective of the current study is to investigate the relative bioavailability of three trial formulations of BI 207127, the trial formulation 2 (TFII), the final formulation (FF), and a FF modified formulation. All formulations are supplied as film-coated Tablets and administered as single dose treatments of BI 207127 (3 film-coated Tablets) in healthy volunteers, with the aim to compare the bioavailability of the three formulations. All treatments will be applied fed, 30 minutes after start of the intake of a standard normal breakfast.
