KORSUVA™ Injection Phase 3 Program Update
KALM-1 Phase 3 Trial
KALM-1 is a multicenter, randomized, double-blind, placebo-controlled 12-week treatment trial in the U.S. with a 52-week open label extension phase that is designed to evaluate the safety and efficacy of 0.5 mcg/kg KORSUVA CR845/difelikefalin injection in 350 hemodialysis patients with moderate-to-severe pruritus.
The primary efficacy endpoint is the proportion of patients achieving at least a 3‑point improvement from baseline in the weekly mean of the daily 24‑hour Worst Itch Numeric Rating Scale (NRS) score at week 12. In a completed Phase 2 trial, the proportion of patients with an improvement from baseline in the weekly mean Worst Itch NRS score of ≥3 points at week 8 was statistically significantly higher in the CR845/difelikefalin 0.5 mcg/kg group compared to the placebo group (64% vs. 29%; p<0.01). 1
Secondary endpoints include assessment of itch-related quality of life changes measured using the validated self-assessment 5-D itch and Skindex-10 scales, as well as the proportion of patients achieving > 4-point improvement from baseline in weekly mean of the daily 24-hour Worst Itch NRS score at week 12.
KALM-2 Phase 3 Trial
Phase 3 Safety Trial
In 2017, the Company initiated a 52-week Phase 3 safety trial that is designed to enroll up to 240 hemodialysis patients with CKD-aP. This open-label trial is evaluating the long-term safety of KORSUVA (CR845/ difelikefalin) Injection at the dose of 0.5mcg/kg and has enrolled more than 200 patients. Thus far, over 100 patients have completed at least six months of treatment, with approximately 40 percent of these through the one-year treatment period. To date, the safety and tolerability have been consistent with data reported in Phase 2 trials of KORSUVA Injection in hemodialysis patients with CKD-aP. Additionally, based on a recent Independent Data Safety Monitoring Board evaluation, no new safety signals have been observed.
