NEW HAVEN, Conn., Feb. 1, 2022 /PRNewswire/ -- Trevi Therapeutics, Inc. (Nasdaq: TRVI) is a clinical-stage biopharmaceutical company developing an investigational therapy Haduvio™ (nalbuphine ER) to treat serious neurologically mediated conditions. Today, Trevi announced that it has completed enrollment in its Phase 2b/3 PRISM trial for pruritus associated with prurigo nodularis (PN) and expects to report top-line data in the second quarter of 2022.
"We are pleased to have completed enrollment in our Phase 2b/3 PRISM trial and look forward to reporting top-line data in the second quarter of this year," said Jennifer Good, President and CEO. "This is an important milestone in the development of Haduvio which is the lead oral compound in clinical development for pruritus in PN and which we believe may offer an important treatment option to these seriously impacted patients. By targeting the pruritus associated with prurigo nodularis, Haduvio is designed to break the itch-scratch cycle which has a significant impact on patients' quality of life. We look forward to seeing these results and advancing the development of Haduvio to address the unmet need of patients with pruritus across conditions."
The PRISM trial is a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of Haduvio for severe pruritus in patients with PN. In the trial, subjects are randomized equally across two treatment groups (oral Haduvio 162 mg or placebo, twice daily including an initial 2-week blinded titration period). The primary endpoint of the trial is the proportion of subjects achieving a greater than or equal to 4-point improvement in the weekly mean Worst Itch Numerical Rating Scale (WI-NRS) score at Week 14 compared to baseline. The planned enrollment for the trial was approximately 360 subjects.
The Company previously announced that the U.S. Food and Drug Administration (FDA) granted Fast Track designation of nalbuphine ER for the proposed indication of reduction of moderate to severe pruritus in patients with PN. Fast Track designation is intended to facilitate development and expedite review of drugs to treat serious and life-threatening conditions so that an approved product can reach the market expeditiously.
About Trevi Therapeutics, Inc.
Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on the development and commercialization of the investigational therapy Haduvio to treat serious neurologically mediated conditions. Trevi is conducting a Phase 2b/3 clinical trial of Haduvio for the treatment of chronic pruritus associated with prurigo nodularis (PN) and a Phase 2 trial for chronic cough in patients with idiopathic pulmonary fibrosis (IPF). Trevi is also developing Haduvio for the treatment of levodopa-induced dyskinesia (LID) in patients with Parkinson's disease. These conditions share a common pathophysiology that is mediated through opioid receptors in the central and peripheral nervous systems.
Founded in 2011, Trevi Therapeutics is headquartered in New Haven, CT.
Haduvio, an investigational therapy, is an oral extended-release (ER) formulation of nalbuphine. Nalbuphine is a mixed ĸ-opioid receptor agonist and µ-opioid receptor antagonist that has been approved and marketed as an injectable for pain indications for more than 20 years in the United States and Europe. The ĸ- and µ-opioid receptors are known to be critical mediators of itch, cough and certain movement disorders. Nalbuphine's mechanism of action may also mitigate the risk of abuse associated with µ-opioid agonists because it antagonizes, or blocks, µ-opioid receptors. Parenteral nalbuphine is not currently classified as a controlled substance by the DEA in the United States or by regulatory authorities in most of Europe. Trevi intends to propose Haduvio as the trade name for nalbuphine ER. Nalbuphine ER (Haduvio) is an investigational therapy that has been granted Fast Track designation by the FDA for the proposed indication of reduction of moderate to severe pruritus in patients with prurigo nodularis. Its safety and efficacy have not been evaluated by any regulatory authority.
