Outcome Measures

Primary Outcomes (9)

  • Safety and tolerability as determined by number of subjects with adverse events

    up to 3 months

  • Determination of pharmacokinetics parameters

    \- maximum concentration (Cmax)

    up to 3 months

  • Determination of pharmacokinetics parameters

    \- time of the maximum measured concentration (Tmax)

    up to 3 months

  • Determination of pharmacokinetics parameters

    \- area under the concentration-time curve from time zero to the last quantifiable concentration time-point (AUClast)

    up to 3 months

  • Determination of pharmacokinetics parameters

    \- area under the concentration-time curve from time zero extrapolated to infinity (AUCinf)

    up to 3 months

  • Determination of pharmacokinetics parameters

    \- elimination rate constant

    up to 3 months

  • Determination of pharmacokinetics parameters

    \- terminal elimination half life (t½)

    up to 3 months

  • Determination of pharmacokinetics parameters

    \- clearance (CL)
