Announced Positive Outcome of Sample Size Re-Estimation Analysis for PRISM Trial

Strong Enrollment in PRISM Trial After Lifting of COVID-19 Restrictions

Announces $14 Million Term Loan - Cash Position Expected to Fund Operations into the First Half of 2022 

NEW HAVEN, Conn., Aug. 13, 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 June 30, 2020, as well as recent business updates.

“We are pleased with how the Trevi team was able to manage the continued execution of the PRISM trial in the face of the COVID-19 pandemic restrictions. The Company announced the positive outcome of the sample size re-estimation analysis and continued to activate clinical sites virtually,” said Jennifer L. Good, President and CEO of Trevi Therapeutics. “Once the screening and enrollment restrictions were lifted in the PRISM trial, we were able to rapidly restart screening and enrollment in most of our sites. We now have approximately 80% of our sites screening patients and have had our strongest two months of enrollment thus far in the trial. In addition, we are pleased to announce the execution of a non-dilutive $14 million term loan which we expect will extend our cash runway into the first half of 2022, past the anticipated top-line results from the PRISM trial which are expected in the fourth quarter of 2021.”

Key Business Updates

• Phase 2b/3 PRISM trial of Haduvio for severe pruritus in patients with prurigo nodularis: The Company completed the pre-specified sample size re-estimation (SSRE) analysis in July and based on the recommendation of the independent Data Monitoring Committee, we increased the trial size from the initial target enrollment of 240 to 360 subjects to maintain statistical power for the primary endpoint. The pace of enrollment has accelerated since the removal of most COVID-19 screening and enrollment restrictions and approximately 155 subjects have been enrolled in the study. We expect to complete enrollment in the third quarter of 2021 and 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 is amending the study protocol to reduce the number of in-person visits to facilitate this study being completed in an at-risk patient population for COVID-19.  The Company is planning for a restart of this trial in the second half of 2020.
• Entered into $14 million term loan with Silicon Valley Bank: The Company entered into a $14 million term loan with Silicon Valley Bank on August 13, 2020 which will bolster our balance sheet and extends our cash runway into the first half of 2022. The term loan requires monthly interest-only payments through February 28, 2022, followed by monthly payments of principal and interest until February 1, 2024. Interest on the term loan initially accrues at a floating per annum rate of the greater of (i) the prime rate plus 1.0% and (ii) 4.25%. Other material terms related to the term loan can be found in the Company’s Form 10-Q.

Second Quarter 2020 Financial Highlights

Cash position: As of June 30, 2020, the Company had total cash and cash equivalents of $44.2 million, compared to $57.3 million as of December 31, 2019.

Research and development (R&D) expenses: R&D expenses for the second quarter of 2020 were $4.9 million compared to $5.5 million in the same period in 2019. The decrease was primarily due to decreased activity in our Phase 2 trial in chronic cough in patients with IPF due to the halting of enrollment and treatment of patients as a result of the COVID-19 pandemic.   

General and administrative (G&A) expenses: G&A expenses for the second quarter of 2020 were $2.5 million compared to $1.9 million in the same period in 2019. The increase was primarily due to an increase in stock-based compensation expenses and an increase in expenses related to being a public company.

Net loss: For the second quarter of 2020, the Company reported a net loss of $7.4 million, compared to a net loss of $7.3 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.
