Study to Compare Properties of Epratuzumab When Given as an Injection Under the Skin or Directly Into the Blood

Overview

To assess how the absolute bioavailability, dose proportionality, pharmacokinetics, safety and tolerability of epratuzumab compared when given as a subcutaneous (sc) injection as to when given as an intravenous (iv) infusion in Caucasian and Japanese healthy volunteers.

    • Time Frame: From Baseline (Day 1 pre-dose) to Day 85 (End of study)

Secondary Measures

  • Time of observed Cmax (tmax)
    • Time Frame: From Baseline (Day 1 pre-dose) to Day 85 (End of study)
  • Apparent terminal half-life (t½)
    • Time Frame: From Baseline (Day 1 pre-dose) to Day 85 (End of study)
