Study summary

This is an intermediate-size patient population expanded access protocol for the use of intravenous (IV) difelikefalin for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adult patients undergoing hemodialysis.

Read the detailed description

Visits during the expanded access program will consist of a Baseline Visit to confirm eligibility and an End of Treatment visit. Patients will receive IV difelikefalin at a dose of 0.5 mcg/kg after each dialysis session, generally 3 times per week. The End of Treatment visit will be defined as the first dialysis visit following the last dose of IV difelikefalin under the intermediate-size patient population expanded access protocol.
