Masking: Open Label
Primary Purpose: Treatment
Official Title: A Single-Dose, Fixed-Sequence, Two-Period, Two−Treatment Study to Evaluate the Absorption, Distribution, Metabolism, and Excretion of TD−1211 Following an Intravenous Infusion and an Oral Dose of [14C]TD−1211 in Healthy Male Subjects

  • Peak plasma concentration (Cmax) [ Time Frame: 0 to 168 hours postdose ]
  • Time to peak plasma concentration (Tmax) [ Time Frame: 0 to 168 hours postdose ]
  • Half-life (T 1/2) [ Time Frame: 0 to 168 hours postdose ]
  • Percent total recovery of radioactivity in blood, urine, and feces [ Time Frame: 0 to 312 hours postdose ]

Secondary Outcome Measures:
  • Number of participants with adverse events [ Time Frame: Baseline to 14 days ]

Detailed Description:
This study will provide information regarding the metabolic pathway of TD 1211, the need for evaluation of potential drug-drug interactions, the need for studies in special populations and the absolute oral bioavailability of TD-1211. The administration of radiolabeled drug is necessary to fully characterize the rates and routes of elimination of TD 1211, providing further quantitative information on the disposition of TD 1211. The results from this study will allow a more comprehensive comparison between animal and human routes of elimination and metabolic profiles of TD 1211.
