Outcome Measures

Primary Outcomes (2)

  • Determination of the effect of dexpramipexole on the pharmacokinetics (PK) parameters of the CYP2C9 probe substrate warfarin including: AUC: area under the plasma-concentration time curve over a specified time period and Cmax: Maximum observed plasma c

    pre-dose and at 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96 and 144 hours after warfarin administration in each dosing period

  • PK parameters of dexpramipexole including but not limited to AUC: area under the plasma-concentration time curve over a specified time period and Cmax: Maximum observed plasma concentration

    pre-dose and at 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8 and 12 hours after administration of the morning dexpramipexole dose on Day 1 and Day 12 of Period 2
