Enteris BioPharma's "Feasibility-to-Licensing" Partner, Cara Therapeutics, Initiates Phase 2 Trial of Peptelligence®-Engineered Oral KORSUVA™ for Pruritus in Patients with Atopic Dermatitis
BOONTON, N.J., July 11, 2019 /PRNewswire/ -- Enteris BioPharma, Inc., a biotechnology company developing innovative drug products built around its proprietary delivery technologies, congratulates Cara Therapeutics (Nasdaq: CARA) on the successful initiation of its Phase 2 clinical trial of Oral KORSUVA™ (CR845/difelikefalin) for the treatment of pruritus in patients with atopic dermatitis (AD). The tablet formulation of Oral KORSUVA, which was engineered using Enteris' proprietary oral peptide delivery technology, Peptelligence®, is now the subject of three separate, pruritus-focused Phase 2 clinical trials.
The Oral KORSUVA Phase 2 clinical trial in pruritus associated with AD is a multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of Oral KORSUVA for moderate-to-severe pruritus in approximately 240 adult subjects with AD. Subjects will be randomized to three tablet strengths of Oral KORSUVA: 0.25 mg, 0.5 mg and 1 mg taken twice daily (BID) vs. placebo for 12 weeks followed by a 4-week active extension phase. The primary efficacy endpoint is the change from baseline in the weekly mean of the daily 24-hour Itch Numeric Rating Scale (I-NRS) score at Week 12 of the treatment period. Cara is also investigating Oral KORSUVA in two additional Phase 2 clinical trials for the treatment of pruritus in patients with hepatic impairment due to primary biliary cholangitis (PBC) and pruritus in patients with stage III-V chronic kidney disease (CKD).
"We commend Cara Therapeutics on the continued expansion of its Oral KORSUVA pipeline, which now boasts three ongoing Phase 2 clinical trials in separate pruritus indications. There is much to be excited about in the potential of Oral KORSUVA, and we welcome the opportunity to continue our successful work with Cara to advance these important studies," said Joel Tune, chief executive officer and executive chairman of Enteris BioPharma. "Given the convenience and marketability of an orally administered tablet in comparison to an injection, the ability of our Peptelligence® platform to enable the oral delivery of peptide therapeutics, such as CR845/difelikefalin, is a potential game-changer for numerous drugs in development and on the market. Cara's recent successes, alongside the advancement of our internal pipeline, highlighted by Ovarest®, epitomize this vast potential."
The oral tablet formulation of CR845/difelikefalin was developed in accordance with a Manufacturing and Clinical Supply Agreement whereby Enteris utilized its Peptelligence technology to enable the active ingredient, which was initially formulated for I.V. or injection administration, to be delivered orally. Under the terms of the "Feasibility-to-Licensing" program, Enteris will continue to manufacture the oral tablet formulation of CR845/difelikefalin for current and potential future studies through Phase 2 as needed by Cara's development plans. Cara Therapeutics has the opportunity to negotiate a Phase 3/commercial license to the Peptelligence technology for oral CR845/difelikefalin from Enteris at any time.
"We are excited to initiate this latest Phase 2 trial of Oral KORSUVA and the opportunity to extend our work with Enteris to the development of a potential novel oral therapeutic option for the treatment of pruritus in patients with AD," stated Derek Chalmers, Ph.D., D.Sc., president and chief executive officer of Cara Therapeutics. "Pruritus affects nearly all atopic dermatitis patients, significantly impacting patients' quality of life, including sleep disruption, altered eating habits, anxiety and depression. Like our other pruritus programs, we believe that Oral KORSUVA may provide a potential new, first-in-class therapeutic approach to treat this unmet clinical need."
