NEW HAVEN, Conn., Nov. 9, 2023  /PRNewswire/ -- Trevi Therapeutics, Inc. (Nasdaq: TRVI), a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio™ (oral nalbuphine ER) for the treatment of chronic cough in idiopathic pulmonary fibrosis (IPF), refractory chronic cough (RCC), and prurigo nodularis, today announced financial results for the quarter ended September 30, 2023, as well as provided business updates.

"We are thrilled to have initiated our Phase 2a RIVER trial of Haduvio in patients with refractory chronic cough, which builds on the strength of the clinical data seen with Haduvio in IPF chronic cough," said Jennifer Good, President and CEO of Trevi Therapeutics. "Refractory chronic cough impacts up to 10% of the adult population globally. We believe Haduvio is well-positioned in IPF chronic cough, as well as in RCC, based on its ability to target cough centrally and peripherally which potentially supports the ability to work across a wide range of cough conditions."

Key Business Updates

• Initiated the Phase 2a RIVER trial in patients with refractory chronic cough and expect topline data in the second half of 2024. The RIVER trial is a double-blind, randomized, placebo-controlled, 2-period crossover study evaluating the safety and efficacy of Haduvio in reducing chronic cough in RCC subjects. Approximately 60 RCC subjects are expected to be randomized with a 1:1 stratification between those with 10-19 coughs/hour (moderate 24-hour cough frequency) and those with ≥ 20 coughs/hour (high 24-hour cough frequency).
• Expect to initiate the Phase 2b dose-ranging trial of Haduvio for the treatment of chronic cough in IPF in the fourth quarter of 2023 and the Phase 1b trial to evaluate the effect of Haduvio on respiratory physiology in patients with IPF in the first quarter of 2024.
• Secured IV butorphanol supply for the human abuse potential study and expect to initiate dosing in the first quarter of 2024, with topline data expected in the second half of 2024.
• Announced preliminary results from the open-label extension portion of the Phase 2b/3 PRISM trial in prurigo nodularis in which 151 subjects completed the open label extension portion of the trial. The safety data over 52 weeks of treatment demonstrated that Haduvio was well-tolerated and consistent with the 14-week blinded safety data. In addition, there was a continued reduction in Worst Itch Numerical Rating Scale, or WI-NRS, scores observed among participants who remained in the study through 52 weeks of treatment.
• Ended the third quarter of 2023 with $88.9 million in cash, cash equivalents and marketable securities.

Third Quarter 2023 Financial Highlights

Research and development (R&D) expenses: R&D expenses for the third quarter of 2023 increased to $6.3 million from $5.8 million in the same period in 2022. The increase was primarily due to higher startup costs and consultant services associated with our chronic cough programs as well as an increase in personnel-related expenses. These increases were partially offset by a decline in clinical development expenses related to our completed Phase 2b/3 PRISM trial and our Phase 2 CANAL trial as well as decreased purchases of clinical trial supplies, among other factors.

General and administrative (G&A) expenses: G&A expenses were $2.7 million in the third quarter of 2023 compared to $2.6 million in the same period in 2022.

Other income, net: Other income, net was $1.3 million in the third quarter of 2023 compared to other income, net of $0.1 million in the same period in 2022. The change was primarily due to an increase in interest income and reduced interest expense due to the payoff of the SVB Term Loan in May 2023.

Net loss: For the third quarter of 2023, the Company reported a net loss of $7.7 million, compared to a net loss of $8.3 million in the same period in 2022.

About Trevi Therapeutics, Inc.
Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio™ (oral nalbuphine ER) for patients with chronic cough in idiopathic pulmonary fibrosis (IPF), refractory chronic cough (RCC), and prurigo nodularis. Haduvio is a dual ĸ-opioid receptor agonist and µ-opioid receptor antagonist that works both centrally in the brain as well as peripherally in the lungs and has the potential for a synergistic antitussive effect to treat chronic cough.

The impact of chronic cough is significant and often leads to a decline in patients' social, physical, and psychological quality of life. In IPF, chronic cough may lead to worsening disease and may be associated with a higher risk of progression, death, or need for lung transplant. There are no approved therapies for the treatment of chronic cough in IPF and current treatment options provide minimal relief to patients. RCC affects up to 10% of the adult population and Haduvio's expansion into RCC has the potential to reach patients suffering from moderate to severe chronic cough. There are also no approved therapies for RCC in the US or Europe.

Parenteral nalbuphine is not scheduled by the U.S. Drug Enforcement Agency. Trevi intends to propose Haduvio as the trade name for oral nalbuphine ER. Its safety and efficacy have not been evaluated by any regulatory authority.
