Second Quarter 2021 Financial Highlights

Cash position: As of June 30, 2021, the Company had total cash and cash equivalents of $36.4 million, compared to $45.0 million as of December 31, 2020.

Research and development (R&D) expenses: R&D expenses for the second quarter of 2021 were $6.5 million compared to $4.9 million in the same period in 2020. The increase was primarily due to an increase in personnel-related expenses due to increased employee headcount, increased costs associated with higher activity and enrollment in the Company's ongoing Phase 2b/3 PRISM trial, increased purchases of clinical trial supplies and an increase in consulting and professional fees. These increases were partially offset by decreased expenses relating to the Company's Phase 1b clinical trial in patients with chronic liver disease which was completed in the first half of 2020.

General and administrative (G&A) expenses: G&A expenses for the second quarter of 2021 were $2.7 million compared to $2.5 million in the same period in 2020. The increase was primarily due to increased legal and professional fees partially offset by a reduction in personnel-related expenses.

Net loss: For the second quarter of 2021, the Company reported a net loss of $9.8 million, compared to a net loss of $7.4 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.

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 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 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.
