- If approved, KORSUVA™ injection would be first therapy for treatment of pruritus in hemodialysis patients
The FDA grants Priority Review to drug applications for potential therapies that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. The NDA filing is supported by positive data from two pivotal Phase 3 trials – KALM-1, conducted in the
“The FDA acceptance for filing and granting of Priority Review for the KORSUVA NDA marks a significant milestone for Cara and for the substantial number of hemodialysis patients with chronic intractable pruritus,” said
“We are delighted that the FDA accepted and granted Priority Review for this breakthrough therapy. Pruritus in hemodialysis patients is a debilitating condition with a significant impact on quality of life and increased risk for hospitalization and mortality. It impacts up to 40% of dialysis patients around the world. If KORSUVA is approved, we will be able to offer a medicine that is in line with our aim to deliver innovative therapies to patients with high unmet medical needs. We are highly committed to bringing this important new treatment to patients in the
About Chronic Kidney Disease-associated Pruritus (CKD-aP)
CKD-aP is an intractable systemic itch condition that occurs with high frequency and intensity in patients with chronic kidney disease undergoing dialysis. Pruritus has also been reported in patients with stage III-V CKD who are not on dialysis. Aggregate, longitudinal, multi-country studies estimate the weighted prevalence of CKD-aP to be approximately 40% in patients with end-stage renal disease (ESRD), with approximately 25% of patients reporting severe pruritus. The majority of dialysis patients (approximately 60 to 70%) report pruritus, with 30 to 40% reporting moderate or severe pruritus.1,2,3 Recent data from the ITCH National Registry Study showed that among those with pruritus, approximately 59% experienced symptoms daily or nearly daily for more than a year. Given its association with CKD/ESRD, most afflicted patients will continue to have symptoms for months or years, with currently employed antipruritic treatments, such as antihistamines and corticosteroids, unable to provide consistent, adequate relief. Moderate-to-severe chronic pruritus has repeatedly been shown to directly decrease quality of life, contribute to symptoms that impair quality of life (such as poor sleep quality), and is associated with depression.4 CKD-aP is also an independent predictor of mortality among hemodialysis patients, mainly related to increased risk of inflammation and infections.
