Chronic kidney disease associated itching (CKD-aP) is a refractory systemic itching disease that occurs frequently and with high intensity in patients with chronic kidney disease undergoing dialysis. There have also been reports of itching in stage III-V CKD patients without dialysis. Comprehensive, longitudinal, and multinational studies estimate that the weighted prevalence of CKD-aP in end-stage renal disease (ESRD) patients is approximately 40%, with approximately 25% of patients reporting severe itching.


On August 23, 2021, Cara Therapeutics and Vifor Pharma announced that the Food and Drug Administration (FDA) approved Korsuva (difelikefalin) injection for the treatment of moderate to severe itching related to chronic kidney disease in adults undergoing hemodialysis. Korsuva injection is a first in class κ Opioid receptor (KOR) agonists act on the peripheral nervous system of the human body.

Cara Therapeutics has requested the FDA to prioritize the review of new drug applications (NDAs).
