Evaluation Of SB-751689 Administered At Supratherapeutic Dose Levels In Healthy Adult Subjects.
A Two-Part Dose-Rising Study to Evaluate the Safety, Tolerability and Pharmacokinetics of SB-751689 When Administered as an Oral Formulation at Supratherapeutic Dose Levels in Healthy Adult Subjects.
This study will evaluate the safety, tolerability and exposure of SB-751689 when administered alone at supratherapeutic doses and when SB-751689 is co administered with ketoconazole, a PGP/CYP3A4 inhibitor that increases exposure of SB-751689. Data from this study will enable the planning and conduct of a QTc study for SB-751689.
