Cara Therapeutics, Inc. (CARA) Reports Clinical Updates

Cara Therapeutics, Inc. (CARA), a biopharmaceutical company focused on developing and commercializing new chemical entities designed to alleviate pruritus by selectively targeting peripheral kappa opioid receptors, or KORs, today announced that it is on track to report topline data in the second quarter of 2020 from its ongoing pivotal KALM-2 Phase 3 global trial of KORSUVA™ Injection in hemodialysis patients with moderate-to-severe chronic kidney disease-associated pruritus (CKD-aP). The Company also plans to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for KORSUVA Injection in the second half of 2020.

“Despite the ongoing situation with COVID-19, and in accordance with the FDA’s updated guidance for conducting clinical trials, we are pleased that we remain in-line with our timetable to report topline data from KALM-2 in the second quarter,” said Derek Chalmers, Ph.D., D.Sc., President and Chief Executive Officer of Cara Therapeutics. “We continue to make significant progress across our entire Phase 3 program for KORSUVA Injection, including supportive safety studies, and still expect to submit our NDA in the second half of this year.”

Cara is also currently evaluating Oral KORSUVA in two ongoing Phase 2 trials for atopic dermatitis (AD) patients with moderate-to-severe pruritus and patients with pruritus and hepatic impairment due to primary biliary cholangitis (PBC), respectively. As previously announced, the Company expects to complete an interim statistical analysis for the ongoing Phase 2 trial in AD patients in the second quarter of this year. In addition, data from the previously reported positive Phase 2 dose-ranging trial of Oral KORSUVA for the treatment of pruritus in patients with moderate-to-severe CKD will be presented as a late-breaker oral virtual presentation at the National Kidney Foundation Spring Clinical Meeting on March 26, 2020.

About the KALM-2 Phase 3 Trial
KALM-2 is a Phase 3, global, multicenter, randomized, double-blind, placebo-controlled, 12-week trial (with a 52-week open-label extension phase) designed to evaluate the safety and efficacy of 0.5 mcg/kg KORSUVA (CR845/difelikefalin) Injection in 430 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 Itching Intensity Numeric Rating Scale (WI-NRS) score at week 12. Secondary endpoints include assessment of the proportion of patients achieving >4-point improvement from baseline in weekly mean of the daily 24-hour WI-NRS score at week 12 as well as itch-related quality of life changes measured using the validated self-assessment 5-D itch and Skindex-10 scales.

The pivotal KALM-1 Phase 3 US trial is complete and topline data were reported in May 2019. The trial met the primary endpoint, with a statistically significant improvement in the proportion of patients on KORSUVA Injection achieving a 3-point or greater improvement in the mean WI-NRS score versus placebo (p=0.000019). The trial also met all secondary endpoints and KORSUVA Injection was generally well-tolerated through 12 weeks of treatment with a safety profile consistent with prior clinical trials.

About Cara Therapeutics

Cara Therapeutics is a clinical-stage biopharmaceutical company focused on developing and commercializing new chemical entities designed to alleviate pruritus by selectively targeting peripheral KORs. Cara is developing a novel and proprietary class of product candidates, led by KORSUVA (CR845/difelikefalin), a first-in-class KOR agonist that targets KORs located in the peripheral nervous system and on immune cells. In the Company’s KALM-1 Phase 3 trial and two Phase 2 trials, KORSUVA (CR845/difelikefalin) Injection has demonstrated statistically significant reductions in itch intensity and concomitant improvement in pruritus-related quality of life measures in hemodialysis patients with moderate-to-severe CKD-aP and is currently being investigated in Phase 3 trials in hemodialysis patients with CKD-aP. Oral KORSUVA is in Phase 2 trials for the treatment of pruritus in patients with CKD, AD and PBC.
