STAMFORD, Conn. — Cara Therapeutics, Inc. today announced it will focus its resources on the oral difelikefalin Phase 2/3 clinical program in notalgia paresthetica (NP) and significantly reduce its operating expenses. These measures will extend the Company’s cash runway into 2026, enabling the expected completion of the NP clinical program.
“We are sharpening our clinical focus on the rapidly progressing Phase 2/3 study in NP, which we believe is the therapeutic indication with the greatest commercial potential for oral difelikefalin,” said Christopher Posner, President and Chief Executive Officer of Cara Therapeutics. “Following careful consideration, we have decided to discontinue our work in advanced chronic kidney disease (CKD). I would like to thank the patients and investigators who have participated in our advanced CKD clinical program, as well as our employees for their commitment to transforming the lives of CKD patients suffering from pruritus.”
Mr. Posner continued, “Unfortunately, as a result of the difficult decision to restructure the Company, many of our talented team members will depart the organization. I am deeply grateful for their dedicated service and support of our mission. We expect the changes we are making to extend our cash runway into 2026, allowing us to reach all expected key value-inflection milestones in the NP clinical program.”
Focus on Late-Stage Notalgia Paresthetica Clinical Program
Enrollment in the Phase 2/3 clinical program evaluating oral difelikefalin for the treatment of moderate-to-severe pruritus in patients with NP, known as KOURAGE, is progressing ahead of the Company’s projections. A data readout from the dose-finding portion of the program is expected in the third quarter of 2024. Final topline results from the first pivotal study are expected by the end of 2025 with the second pivotal study results in early 2026.
NP is a common but under-recognized neuropathic disorder characterized by chronic pruritus affecting the upper back. NP is challenging to manage, as there are currently no FDA-approved therapies to treat the disorder. Oral difelikefalin is the only therapy in development for NP. NP represents a sizable, underserved patient population with an estimated addressable market of 650,000 patients in the U.S. who are under the care of a healthcare provider, not accounting for those who are undiagnosed.
Leadership Update
Frédérique Menzaghi, Ph.D., Chief Scientific Officer and SVP of Research & Development, will depart the Company, effective February 2, 2024.
“On behalf of the entire Cara team, I would like to express our sincere gratitude to Fred for all her contributions and dedication to the organization over the past 20 years. As one of Cara’s founders, her scientific leadership helped shape the trajectory of the company from start-up to a publicly traded company,” said Mr. Posner.
About the KOURAGE Phase 2/3 Clinical Program in Notalgia Paresthetica
KOURAGE is a Phase 2/3 clinical program evaluating oral difelikefalin for the treatment of moderate-to-severe pruritus in patients with notalgia paresthetica (NP). The program is comprised of two studies – KOURAGE 1 and KOURAGE 2 – which are double-blind, placebo-controlled, 8-week studies with patients allowed to roll-over into open-label 52-week extensions.
KOURAGE 1 is composed of two parts. The dose-finding portion of KOURAGE 1 (Part A) is expected to include 200 patients who will be randomized equally to four arms (0.25 mg BID, 1.0 mg BID, 2.0 mg BID, placebo BID). The Company expects a data readout from the dose-finding portion of KOURAGE 1 in the third quarter of 2024. This readout will provide key information, specifically the dose and sample size to initiate the Phase 3 portions of the program – Part B of KOURAGE 1 and the second pivotal study KOURAGE 2.
Part B and KOURAGE 2 will be double-blind, placebo-controlled, 8-week studies with patients randomized 1:1 to either difelikefalin or matching placebo. The primary endpoint will be the proportion of patients with a ≥4-point improvement at Week 8 from baseline in the worst itch numeric rating scale. The Company expects final topline results from the first pivotal study by the end of 2025 with the second study by early 2026.
