The FDA has approved Korsuva (difelikefalin) from Cara Therapeutics Inc. for pruritis in patients undergoing hemodialysis, following a fast review. Korsuva is the first therapy approved by the FDA in the indication and is the first ever approval for the Stamford, Conn.-based company.
Despite stock-denting phase II data with the oral version of Korsuva (difelikefalin) for moderate to severe pruritis in patients with moderate to severe atopic dermatitis (AD), Cara Therapeutics Inc. CEO Derek Chalmers said the outcome “prioritizes moving forward. We got what we needed from the phase II trial,” which identified the patients most sensitive to the drug, nailed down a dose spectrum, and equipped the company to power a registrational effort, he said.
Despite the higher placebo response than a previous, identically designed experiment turned up, Cara Therapeutics Inc.’s Kalm-2 phase III study Korsuva (CR-845/difelikefalin) for injection handily reached its primary endpoint in hemodialysis patients with moderate to severe chronic kidney disease-associated pruritus (CKD-aP).
