Primary Outcome Measures:
  • Number of adverse events including type and severity [ Time Frame: Date of randomization up to Day 43 ]
    Number, type and severity of adverse events, vital signs, electrocardiogram (ECGs), laboratory tests, and physical examinations will be reported during the study from randomization up to Day 43

  • Number of adverse events including type and severity of a priming IV dose followed by an escalating second IV dose [ Time Frame: Date of randomization up to Day 36 ]
    Number, type and severity of adverse events, vital signs, electrocardiogram (ECGs), laboratory tests, and physical examinations will be reported during the study from randomization up to Day 36


Secondary Outcome Measures:
  • Blood concentration of XmAb7195 and blood levels of human anti-human antibodies after single-dose IV administration of XmAb7195 [ Time Frame: Time of dosing up to Day 43 ]
    Pharmocokinetic (PK) analysis for levels of XmAb7195 will be determined in subjects blood from time of initial dosing up to Day 43

  • Blood concentration of XmAb7195 and blood levels of human anti-human antibodies after a priming IV dose followed by an escalating second IV dose of XmAb7195 [ Time Frame: Time of dosing up to Day 36 ]
    Presence of human anti-human antibodies will be assessed from time of dosing up to Day 36
