Primary Outcome Measures
NameTimeMethod
Safety and tolerability as assessed by the incidence and severity of adverse eventsFrom Day 1 (first dose) to Day 169 (last follow-up visit)

Safety and tolerability of multiple dose levels of CDX-0159 as determined by drug related adverse events

Secondary Outcome Measures
NameTimeMethod
Pharmacokinetic evaluationFrom Day 1 (before first dose) to Day 169 (last follow-up visit)

CDX-0159 serum concentrations will be measured at specified visits

Clinical effect of CDX-0159 on pruritusFrom Day 1 (first dose) to Day 57 (week 8)

The mean percent change from baseline to Week 8 in the weekly average score of worst intensity itch per a numeric rating scale. The Worst Itch-Numerical Rating Scale (WI-NRS) ranges from 0 = "no itch" to 10 ="worst imaginable itch" for their worst intensity prurigo nodularis itch in the preceding 24-hr period.
