CR845-CLIN3103: A Global Study to Evaluate the Safety and Efficacy of CR845 in Hemodialysis Patients With Moderate-to-Severe Pruritus


Brief description of study

This is a multicenter, international study to evaluate the safety and efficacy of intravenous (IV) CR845 at a dose of 0.5 mcg/kg administered after each dialysis session. The study includes a 12-week randomized, double-blind, placebo-controlled Phase and a 52-week Open-label Extension Phase.

Detailed Study Description

Double-blind Phase: The Double-blind Phase of the study will consist of a Screening Visit, a 7-day Run-in Period, and a 12-week Double-blind Treatment Period. Informed consent will be obtained prior to performing any study-specific procedures. The Screening Visit will occur within 7 to 28 days prior to randomization to assess eligibility.

Open-label Extension Phase: Patients who received at least 30 doses of study drug (either active or placebo) during the 12-week Double-blind Treatment Period and continue to meet other eligibility criteria will have the option to receive open label CR845 for an additional 52 weeks.

The last dose of open-label study drug will be administered at the last dialysis visit on Week 52, or Early Termination.

Follow-up Period: A final safety Follow up Visit will be conducted 7-10 days after the End of Treatment/Early Termination Visit.

Clinical Study Identifier: NCT03636269
