About CANAL
Interim analysis results from the Phase 2 Cough And NALbuphine (CANAL) trial were statistically significant on the primary efficacy endpoint with a 77% reduction in daytime cough frequency from study baseline for Haduvio, demonstrating a 52% placebo-adjusted reduction in the geometric mean percent change (p<0.0001) (N=26). The secondary endpoints supported the benefit seen in the primary endpoint. Based on the strength and consistency of the efficacy data, Trevi stopped recruitment and expects top-line data for the full set of subjects in the third quarter of 2022. This interim analysis was specifically to assess efficacy. There have been no reported deaths in the CANAL trial and 1 reported Serious Adverse Event (pneumonia) which was not considered treatment related. The CANAL trial is a double-blind, randomized, placebo-controlled, 2-treatment, 2-period crossover efficacy and safety study of nalbuphine ER for chronic cough in patients with IPF taking place in the United Kingdom. The study consists of 2 treatment periods of 3 weeks, with a washout period of 2 weeks after each treatment period. The primary efficacy endpoint is to evaluate the effect of nalbuphine ER tablets on the mean daytime cough frequency at day 22 compared to placebo as measured by an objective cough monitor. More information about the CANAL trial is available at www.clinicaltrials.gov: NCT04030026

About PRISM
The Phase 2b/3 Pruritus Relief through Itch Scratch Modulation (PRISM) trial is a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of Haduvio for severe pruritus in patients with PN. In the trial, subjects are randomized equally across two treatment groups (oral Haduvio 162 mg or placebo, twice daily including an initial 2-week blinded titration period). The primary endpoint of the trial is the proportion of subjects achieving a greater than or equal to 4-point improvement in the weekly mean Worst Itch Numerical Rating Scale (WI-NRS) score at Week 14 compared to baseline. The planned enrollment for the trial was approximately 360 subjects. Top-line data is expected in the second quarter of 2022. More information about the PRISM trial is available at www.clinicaltrials.gov: NCT03497975

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). 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 κ- 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. 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.
