PRISM Trial of Haduvio™ for Severe Pruritus in Patients with Prurigo Nodularis 

Exceeds Halfway Enrollment Milestone

Phase 2 Chronic Cough Trial in Patients with IPF Enrolled First New Subject Post-COVID-19 Restrictions

Cash Position Expected to Fund Operations into the First Half of 2022

NEW HAVEN, Conn., Nov. 11, 2020 (GLOBE NEWSWIRE) -- Trevi Therapeutics, Inc. (Nasdaq: TRVI), a clinical-stage biopharmaceutical company focused on the development and commercialization of Haduvio™ (nalbuphine ER) to treat serious neurologically mediated conditions, today announced financial results for the quarter ended September 30, 2020, as well as business updates.

“We are pleased with the continued progress of our clinical development programs,” said Jennifer L. Good, President and CEO of Trevi Therapeutics. “We recently announced significant developments in both of our ongoing clinical trials by surpassing halfway enrollment in our PRISM trial and enrolling the first new subject in our chronic cough trial in IPF since the study resumed after pausing due to COVID restrictions. We are focused on completing enrollment in both trials and preparing for the next steps in the development of Haduvio.”

Key Business Updates

• Phase 2b/3 PRISM trial of Haduvio for severe pruritus in patients with prurigo nodularis: The Company has enrolled approximately 190 subjects in the trial and reaffirms its guidance that it expects to complete enrollment in the third quarter of 2021 and to report top-line data in the fourth quarter of 2021.
   
• Phase 2 trial of Haduvio for chronic cough in patients with idiopathic pulmonary fibrosis (IPF): The Company resumed screening and enrolling patients in the trial following the pause in the trial due to COVID-19. The Company amended the study protocol to require fewer in-person visits by subjects as well as fewer procedures in order to facilitate the completion of the trial in an at-risk patient population for COVID-19. Additionally, the Company is assessing additional study sites in Germany which could potentially accelerate enrollment and reduce the risks inherent with single-country recruitment during the COVID-19 pandemic.

Third Quarter 2020 Financial Highlights

Cash position: As of September 30, 2020, the Company had total cash and cash equivalents of $53.3 million, compared to $57.3 million as of December 31, 2019. During the third quarter of 2020, the Company received $14.0 million in proceeds from a term loan with Silicon Valley Bank and sold approximately $2.5 million of common stock under the Company’s ATM program. The Company expects its cash position will fund operations into the first half of 2022.

Research and development (R&D) expenses: R&D expenses for the third quarter of 2020 were $4.8 million compared to $5.7 million in the same period in 2019. The decrease was primarily due to decreased activity in the Company’s Phase 2 trial in chronic cough in patients with IPF due to the pausing of enrollment and treatment of patients as a result of the COVID-19 pandemic as well as decreased activity with the completion of the Company’s Phase 1b trial in patients with chronic liver disease.

General and administrative (G&A) expenses: G&A expenses for the third quarter of 2020 were $2.4 million compared to $2.0 million in the same period in 2019. The increase was primarily due to an increase in stock-based compensation expenses and an increase in consulting fees.

Net loss: For the third quarter of 2020, the Company reported a net loss of $7.4 million, compared to a net loss of $7.4 million in the same period in 2019.

About Trevi Therapeutics, Inc.
Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on the development and commercialization of Haduvio to treat serious neurologically mediated conditions. Trevi is currently developing Haduvio for the treatment of chronic pruritus, chronic cough in patients with idiopathic pulmonary fibrosis (IPF) and 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. Trevi is currently conducting a Phase 2b/3 clinical trial of Haduvio, referred to as the PRISM trial, in patients with severe pruritus associated with prurigo nodularis.

Founded in 2011, Trevi Therapeutics is headquartered in New Haven, CT.

About HADUVIO
Haduvio is an oral extended release 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 also mitigates the risk of abuse associated with µ-opioid agonists because it antagonizes, or blocks, µ-opioid receptors. Nalbuphine is currently the only opioid approved for marketing that is not classified as a controlled substance in the United States and most of Europe. Trevi intends to propose Haduvio as the trade name for the nalbuphine ER investigational product. Haduvio is an investigational drug product and its safety and efficacy have not been fully evaluated by any regulatory authority.
