“The approval of Kapruvia^® in Switzerland is the next step on our journey to bring this breakthrough treatment to hemodialysis patients living with CKD-associated pruritus around the world,” said Dr. Klaus Henning Jensen, Chief Medical Officer of CSL Vifor. “There is a high unmet medical need for a targeted therapy to treat moderate-to-severe pruritus, and we are convinced that Kapruvia^® can provide relief to many suffering from this heavy burden. We are very committed to making this therapy available to patients as soon as possible.”

“We are pleased that Kapruvia^® is now approved in Switzerland for hemodialysis patients who are suffering from CKD-associated pruritus,” said Christopher Posner, President and Chief Executive Officer of Cara Therapeutics. “As Cara Therapeutics continues on the path toward becoming the leader in the treatment of chronic pruritus, we are working with our partner VFMCRP to ensure this first-of-its-kind therapy is available to healthcare providers and patients across the globe who greatly need a treatment option.”

Swissmedic approval was supported by positive data from two pivotal phase-III trials – KALM-1, conducted in the U.S. (New England Journal of Medicine 2020; 382:222-232), and the global KALM-2, as well as supportive data from an additional 32 clinical studies.

Kapruvia^® has been submitted in Switzerland as part of an Access Consortium procedure together with Canada (approved in August 2022), as well as Australia and Singapore. Regulatory decisions in these two markets are expected in the second half of 2022.

About Chronic Kidney Disease-associated Pruritus

CKD-associated pruritus 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. 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-associated pruritus is also an independent predictor of mortality and the risk for hospitalization among hemodialysis patients.
