  Purpose

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.

Primary Outcome Measures:
  • Safety and tolerability of SB-751689 doses determined from clinical safety and tolerability data from all adverse event reporting, 12-lead ECGs, vital signs, nursing/physician observation, and safety laboratory tests [ Time Frame: throughout the study ]

Secondary Outcome Measures:
  • PK and of SB-751689 as determined by AUC, Cmax, tmax, and half-life. PD effects (PTH, serum Ca) as determined by AUC, Emax, tmax, maximum change and % change from baseline, duration of effect, duration above ULN for PTH. [ Time Frame: throughout the study ]
