Study Summary

This is a multicenter, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of 3 dose levels of oral CR845 compared to placebo in reducing the intensity of itch in chronic kidney disease (CKD) patients with moderate-to-severe pruritus. This study will consist of a Screening Period, a 7-day Run-in Period, a 12 week Treatment Period, and a Follow-up Visit (approximately 7 days after the last dose of study drug).

Primary Outcome

Intensity of itch will be measured using an NRS used to indicate the intensity of the worst itching over the past 24 hours using a 0 to 10 numeric rating scale, where "0" represents "no itching" and "10" represents "worst itching imaginable". Higher scores meant worse itch intensity.
