Trevi Therapeutics Announces First Quarter 2021 Financial Results and Business Update

Fast Track Designation Granted by FDA for Moderate to Severe Pruritus in Prurigo Nodularis (PN)

New Haven, Conn., May 13, 2021 – Trevi Therapeutics, Inc. (Nasdaq: TRVI), a clinical-stage biopharmaceutical company focused on the development and commercialization of the investigational therapy Haduvio™ (nalbuphine ER) to treat serious neurologically mediated conditions, today announced financial results for the quarter ended March 31, 2021, as well as business updates.

“We continue to make progress in our clinical development programs for the treatment of chronic pruritus in patients with PN and chronic cough in patients with Idiopathic Pulmonary Fibrosis (IPF),” said Jennifer L. Good, President and CEO of Trevi Therapeutics. “Our PRISM trial is over 70% enrolled and we expect to complete enrollment in the second half of this year. We also recently received FDA Fast Track designation for moderate to severe pruritus in PN, evidencing the seriousness of this condition. In addition, our CANAL trial has resumed screening subjects since the COVID-19 shelter in place directive was lifted at the end of March in the UK and we are very pleased to see screening activity resume. We remain focused on completing enrollment in both trials and planning for the next steps in clinical development,” concluded Ms. Good.

The U.S. Food and Drug Administration (FDA) has granted Fast Track designation to nalbuphine ER for the proposed indication of reduction of moderate to severe pruritus in patients with prurigo nodularis. 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.

Cash position: As of March 31, 2021, the Company had total cash and cash equivalents of $41.6 million, compared to $45.0 million as of December 31, 2020. The Company expects its current cash position will fund operations into the second quarter of 2022.

Research and development (R&D) expenses: R&D expenses for the first quarter of 2021 were $5.6 million compared to $6.0 million in the same period in 2020. The decrease was primarily due to a decrease in clinical development expenses related to decreased purchases of clinical trial supplies and decreased expenses reflecting the completion of our Phase 1b clinical trial in patients with chronic liver disease in the first half of 2020. These decreased clinical development expenses were partially offset by increased costs associated with higher activity and enrollment in the Company’s ongoing Phase 2b/3 PRISM trial, an increase in personnel-related expenses and higher consulting and professional fees.

General and administrative (G&A) expenses: G&A expenses for the first quarter of 2021 were $2.5 million compared to $2.6 million in the same period in 2020. The decrease was primarily due to a decrease in stock-based compensation expense.

Net loss: For the first quarter of 2021, the Company reported a net loss of $8.4 million, compared to a net loss of $8.5 million in the same period in 2020.

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.

About Haduvio
Haduvio, an investigational therapy, 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 may also mitigate the risk of abuse associated with µ-opioid agonists because it antagonizes, or blocks, µ-opioid receptors. Nalbuphine is not currently classified as a controlled substance by the DEA in the United States and 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 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.
