Cara Therapeutics Presents Results of Oral Difelikefalin In Painful Itching Disorder

  • Cara Therapeutics Inc CARA announced results from the KOMFORT Phase 2 clinical trial of oral difelikefalin for moderate-to-severe pruritus in notalgia paresthetica (NP). 
  • Notalgia paresthetica (NP) is a nerve disorder that causes intense and sometimes painful itching in the back impacting quality of life.
  • The data will be presented at the European Academy of Dermatology and Venereology (EADV) Congress.
  • The presentation includes data from 125 patients with NP and moderate-to-severe pruritus who were randomized to receive oral difelikefalin 2 mg twice daily or a placebo over an 8-week treatment period.
  • The primary efficacy endpoint of change from baseline in the weekly mean of the itch score was achieved (-4.0 difelikefalin vs. -2.4 placebo). A statistically significant reduction in itch intensity was observed with oral difelikefalin at Day 1 compared to placebo, and the effect was maintained through Week 8.
  • A significantly greater proportion of patients achieved a ≥4-point improvement in the itch score at Week 8 with oral difelikefalin vs. placebo (41% difelikefalin vs. 18% placebo, p=0.007). 
  • A higher proportion of patients receiving oral difelikefalin vs. placebo achieved a complete response (22% difelikefalin vs. 5% placebo)
  • Oral difelikefalin was generally well tolerated, with all adverse events in difelikefalin-treated patients reported as mild or moderate in severity. 
  • Price Action: CARA shares are down 0.27% at $10.93 on the last check Thursday.
