NEW HAVEN, Conn., Jan. 5, 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 expects to perform an interim statistical update in the first quarter of 2022 for its ongoing Phase 2 CANAL trial of Haduvio in patients suffering from chronic cough due to idiopathic pulmonary fibrosis (IPF). Trevi also announced that it expects to end enrollment in its Phase 2b/3 PRISM trial for pruritus associated with prurigo nodularis (PN) by January 31, 2022.

Trevi intends to conduct the interim statistical update for the CANAL trial based on a conditional power assessment. The CANAL trial is a randomized, double-blind, placebo controlled, two-treatment, two-period, crossover study. An independent statistician will review the pre-planned analysis on the primary endpoint of change in daytime cough frequency for oral nalbuphine ER compared to placebo. The information from the statistical update will be used to determine whether proof-of-concept can be established prior to the full enrollment of the study. The Company expects to complete the statistical update in the 1Q 2022.

Trevi continues progress in its PRISM Ph2b/3 trial in pruritus with prurigo nodularis and expects to end enrollment by the end of January. The Company continues to expect top-line data from the 14-week blinded portion of the trial in the 1H 2022.

"We are looking forward to the planned interim statistical update for the CANAL trial and the end of enrollment for the PRISM trial. Both clinical trials are incredibly important to patients and providers as there are currently no therapies approved for either of these indications," said Dr. Bill Forbes, Chief Development Officer. "Up to 85% of IPF patients experience chronic cough. IPF patients consider cough one of their most bothersome symptoms, and one that has a significant impact on their quality of life. We are excited to include this interim statistical update in our CANAL trial with the goal of potentially accelerating further development in this area."

"The majority of IPF patients suffer from chronic cough. For many people, it involves a series of coughing fits throughout the day, leaving them feeling breathless and physically tired. IPF patients often have to withdraw from social activities and give up work, due to their cough, which increases their isolation. We urgently need new treatments for this debilitating condition," said Steve Jones, Chair of Trustees at Action for Pulmonary Fibrosis, UK. "We do not currently have effective treatments for cough associated with IPF," said Liam Galvin, CEO of the European Pulmonary Fibrosis Federation (EU-IPFF). "There is an urgent need for more research into cough related to IPF to help improve overall quality of life of those diagnosed with this life-threatening disease. Patient advocacy has a key role to play in strengthening the IPF patient's voice and raising awareness in an area of high unmet need."

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.

About Haduvio
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. 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.
