Cara Therapeutics Announces CMS Grants TDAPA to KORSUVA™ (difelikefalin) Injection
KORSUVA receives TDAPA reimbursement beginning April 2022
U.S. commercial launch on track for early second quarter 2022
STAMFORD, Conn., Dec. 20, 2021 (GLOBE NEWSWIRE) -- Cara Therapeutics, Inc. (Nasdaq: CARA) today announced that the U.S. Centers for Medicare & Medicaid Services (CMS) has granted Transitional Drug Add-On Payment Adjustment (TDAPA) to KORSUVA™ (difelikefalin) injection in the anti-pruritic functional category. TDAPA will apply to KORSUVA injection beginning April 4, 2022, for two years. KORSUVA injection was approved by the U.S. Food and Drug Administration (FDA) in August 2021 for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adults undergoing hemodialysis.
TDAPA enables payment for new injectable end-stage renal disease (ESRD)-related therapies to be reimbursed outside of the ESRD Prospective Payment System (PPS) bundle.
As KORSUVA injection is just the second product to be approved for TDAPA, CMS expressed in its written communication to Cara and Vifor Pharma, Cara’s U.S. commercial partner for KORSUVA injection, a continuing interest in engaging with the companies regarding potential post-TDAPA support to ensure all beneficiaries with ESRD have access to innovative products such as KORSUVA injection.
“Receiving TDAPA from CMS is a crucial step toward the commercial launch of KORSUVA injection, which we believe will benefit thousands of chronic kidney disease patients undergoing dialysis who suffer from pruritus,” said Christopher Posner, President and Chief Executive Officer of Cara Therapeutics. “We are pleased to have secured TDAPA reimbursement for KORSUVA injection and are encouraged by the willingness of CMS leadership to engage with Cara and Vifor Pharma regarding potential post-TDAPA support.”
“We are pleased to have secured TDAPA reimbursement in the United States for KORSUVA injection effective April 2022, and we look forward to bringing this important treatment option to the people who need it,” said Molly Painter, President USA, Vifor Pharma.

About KORSUVA™ Injection
KORSUVA is a kappa opioid receptor agonist developed in Cara laboratories and indicated for the treatment of moderate-to-severe pruritus associated with chronic kidney disease (CKD-aP) in adults undergoing hemodialysis (HD). KORSUVA Injection is not a federally controlled substance.
Breakthrough Therapy Designation was received from the FDA for KORSUVA Injection for the treatment of CKD-aP in HD patients and the New Drug Application was evaluated by the FDA with Priority Review.
Important Safety Information
Warnings and Precautions
Dizziness, Somnolence, Mental Status Changes, and Gait Disturbances: These adverse reactions, including falls, have occurred in patients taking KORSUVA and may subside with continued treatment. Concomitant use of centrally acting depressant medications, sedating antihistamines, and opioid analgesics may increase the likelihood of these adverse reactions and should be used with caution during treatment with KORSUVA.
Risk of Driving and Operating Machinery: Dizziness, somnolence, and mental status changes have occurred in patients taking KORSUVA. KORSUVA may impair the mental or physical abilities needed to perform potentially hazardous activities such as driving a car and operating machinery. Advise patients not to drive or operate dangerous machinery until the effect of KORSUVA on their ability to do so is known.
The most common adverse reactions (incidence ≥2% and ≥1% higher than placebo) were diarrhea (9.0%), dizziness (6.8%), nausea (6.6%), gait disturbances, including falls (6.6%), hyperkalemia (4.7%), headache (4.5%), somnolence (4.2%), and mental status changes (3.3%).
Use in Specific Populations
Severe Hepatic Impairment: The influence of severe hepatic impairment on the pharmacokinetics of KORSUVA in subjects undergoing hemodialysis (HD) has not been evaluated; therefore, use of KORSUVA in this population is not recommended.
Geriatric Use: The incidence of somnolence was higher in KORSUVA-treated subjects aged 65 years and older (7.0%) than in KORSUVA-treated subjects less than 65 years of age (2.8%). The incidence was comparable in both placebo age groups (3.0% and 2.1%, respectively).
KORSUVA is indicated for the treatment of moderate to severe pruritus associated with chronic kidney disease (CKD-aP) in adults undergoing hemodialysis (HD).
Limitation of Use: KORSUVA has not been studied in patients on peritoneal dialysis and is not recommended for use in this population.

About Chronic Kidney Disease-associated Pruritus
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 anti-pruritic 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.
