Outcome Measures

Primary Outcomes (2)

  • Pharmacodynamic variable: Individual subject cell surface antigen (CD40) occupancy levels over time

    binding of ASKP1240-biotin to B cells

    Days 1-3, 5, 8,15, 22, 29, 43, 60, 75, and 90

  • Pharmacokinetics profile: AUCinf and Cmax

    Area under the plasma concentration-time curve from time 0 extrapolated to infinity (AUCinf) and Maximum concentration of study drug (Cmax)

    Days 1-8,15, 22, 29, 43 and 60

Secondary Outcomes (4)

  • Pharmacokinetics profile: AUClast, tmax, t1/2, Vz, and CLtot

    Days 1-8,15, 22, 29, 43 and 60

  • Total lymphocyte count

    Day -1, Days 1-3, 5, 8,15, 22, 29, 43, and 60

  • Peripheral lymphocyte subset quantification

    Day -1, Days 1-3, 5, 8,15, 22, 29, 43, and 60

  • Safety assessed by recording adverse events, laboratory assessments, vital signs, electrocardiograms (ECGs), physical examination, pulse oximetry, and incidence of anti-ASKP1240 antibody formation

    Up to day 90
