  • CKD-associated pruritus, often known as uremic pruritus or CKD-associated itch, is defined as relentless itching directly related to CKD, without another explainable cause.3,4
  • The condition impacts a patient's quality of life, often causing sleep disturbances, depression and decreased mental and physical functioning.4,5,6
  • In Australia, it is estimated that up to 43% of patients undergoing haemodialysis are moderately to extremely affected by CKD-associated itch.5


MELBOURNE, 13 May 2024


CSL Seqirus welcomes the announcement that Korsuva (difelikefalin) will be available on the Pharmaceutical Benefits Scheme (PBS) from 1 May 2024. Korsuva is the first approved and reimbursed treatment for moderate-to-severe pruritus associated with chronic kidney disease (CKD) in adults undergoing haemodialysis.1,2


CKD-associated pruritus, also referred to as CKD-associated itch, is a persistent itch related to chronic kidney disease – a common condition that results in the loss of normal kidney function over time.3 It particularly impacts those undergoing haemodialysis, a treatment for managing kidney disease that filters out toxins, wastes and extra fluid.4,8


Australians living with CKD-associated itch often experience negative impacts on their quality of life. The condition often leads to sleep disturbances, depression and decreased mental and physical functioning.4,5,6 It has also been associated with an increase in missed haemodialysis sessions, higher rates of hospitalisation and an increase in mortality.4,5


More than two thirds (67%) of haemodialysis patients suffer with itch, however, it is estimated that 43% of patients undergoing haemodialysis are moderately to extremely affected by CKD-associated itch.5 With over 12,000 Australians living with chronic kidney disease currently undergoing haemodialysis, the burden of associated conditions remains high.7


Professor Carol Pollock AO – Nephrologist and Chair of Kidney Health Australia, said the availability of a reimbursed option for CKD–associated pruritus will help clinicians to better manage this condition in their haemodialysis patients and may improve quality of life for those with moderate-to-severe symptoms.


“CKD-associated pruritis is a relentless itch, and up until this point we have had very few options to help manage this condition. The PBS listing of Korsuva is welcome news as it means people whose quality of life is impacted by moderate-to-severe symptoms have a specific and accessible option to help reduce the burden of this condition,” said Professor Pollock.


“CKD-associated itch is often underdiagnosed and undertreated. With the burden of chronic kidney disease remaining high in Australia, it is important we do what we can to improve quality of life for people living with associated conditions.”


Chris Forbes, CEO of Kidney Health Australia – the peak body for kidney health in Australia – welcomed the availability of Australia’s first approved treatment option for CKD-associated itch.


“When we talk about CKD, we don’t often think about the associated conditions, like CKD-associated itch, that can severely impact a person’s life. Experiencing consistent itching because of CKD can affect all facets of a person’s work and social life, including sleep and overall mood. Having a specifically designed treatment option for haemodialysis patients experiencing CKD-associated itch is a significant step forward to reduce the burden of these symptoms in patients with the greatest need,” said Mr Forbes.


Claire Morgan, CSL Seqirus Medical Director for Pharmaceuticals, said the PBS listing is an important milestone for the treatment of CKD-associated itch, and CSL Seqirus is proud to bring to market Australia’s first approved treatment option for this condition.


“This reimbursement provides haemodialysis patients living with moderate-to-severe itch associated with CKD, access to a first-of-its-kind treatment to help manage a condition which can further burden the lives of people living with significant chronic disease. We are committed to improving quality of life for patients living with chronic kidney disease and this listing is evidence of that,” said Ms Morgan.



Korsuva is a medicine used to treat itchy skin in adults with chronic kidney disease who need haemodialysis to clean their blood. Korsuva is given as an injection and works by activating kappa-opioid receptors outside of the brain.
