Management to host a conference call and webcast today at 4:30 p.m. ET 

NEW HAVEN, Conn., May 8, 2025 /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 patients with idiopathic pulmonary fibrosis (IPF) and in patients with refractory chronic cough (RCC), today announced financial results for the quarter ended March 31, 2025, and provided business updates. 

"The RIVER data in patients with RCC demonstrated the clinical significance of Haduvio's centrally and peripherally acting mechanism and its potential across a broad range of chronic cough patients and cough counts," said Jennifer Good, President and CEO of Trevi Therapeutics. "Building on that positive momentum, we look forward to the topline results from the Phase 2b CORAL trial expected this quarter for the treatment of IPF patients with chronic cough. Chronic cough is a significant burden to IPF patients and there are no approved therapies. Trevi is at a pivotal moment with promising data, a dedicated development team advancing trials, and a strong balance sheet to support the continued development of Haduvio."

First Quarter 2025 Financial Results and Recent Business Highlights 

• Enrollment was completed in February 2025 in the Phase 2b CORAL trial of Haduvio in chronic cough patients with IPF and the last patient last visit was completed in April 2025. Topline results for the CORAL trial remain on track for the second quarter of 2025.
• In March, Trevi announced positive topline results from its Phase 2a RIVER trial of Haduvio in patients with RCC (N=66). Haduvio met the primary endpoint with a statistically significant reduction in objective 24-hour cough frequency of 67% from baseline and 57% on a placebo-adjusted basis (p<0.0001). Planned analyses of all pre-specified secondary endpoints at the end of treatment were also statistically significant. The Company is now reviewing the full data set and is in the process of designing the next planned trial of Haduvio in patients with RCC.
• Ended the first quarter of 2025 with $103.3 million in cash, cash equivalents and marketable securities, with expected cash runway into the fourth quarter of 2026.

First Quarter 2025 Financial Highlights 

Research and development (R&D) expenses: R&D expenses for the first quarter of 2025 decreased to $7.8 million from $8.8 million in the same period in 2024, primarily due to decreased clinical development expenses for the Company's Human Abuse Potential study, which was actively enrolling patients in the prior year, partially offset by an increase in personnel related expenses due to increased headcount.  

General and administrative (G&A) expenses: G&A expenses for the first quarter of 2025 increased to $3.7 million from $3.1 million in the same period in 2024, primarily due to an increase in personnel-related expenses.

Net loss: For the first quarter of 2025, the Company reported a net loss of $10.3 million, compared to a net loss of $10.9 million in the same period in 2024.

About Trevi Therapeutics, Inc.   

Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio™ (oral nalbuphine extended-release) for the treatment of chronic cough in patients with idiopathic pulmonary fibrosis (IPF) and in patients with refractory chronic cough (RCC). Haduvio is the first and only investigational therapy to show a statistically significant reduction in cough frequency in clinical trials with IPF chronic cough patients and RCC patients. Haduvio acts on the cough reflex arc both centrally and peripherally as a kappa agonist and a mu antagonist (KAMA), targeting opioid receptors that play a key role in controlling chronic cough. Nalbuphine is not currently scheduled by the U.S. Drug Enforcement Agency. 

Chronic cough is a highly prevalent condition in IPF patients, impacting up to 85% of the IPF population. There are ~150,000 U.S. IPF patients and the impact of chronic cough is significant with patients coughing up to 1,500 times per day. This consistent cough and any associated damage may lead to worsening disease, a higher risk of progression, death, or need for lung transplant. Chronic cough also often leads to a decline in patients' social, physical, and psychological quality of life. There are no approved therapies for the treatment of chronic cough in patients with IPF and current off-label treatment options provide minimal benefit to patients. 

Refractory chronic cough has no approved therapies in the U.S. and is defined as a persistent cough lasting >8 weeks despite treatment for an underlying condition (i.e., asthma, gastroesophageal reflux disease, non-asthmatic eosinophilic bronchitis, and upper airway cough syndrome or post-nasal drip) and includes unexplained chronic cough. RCC affects ~2-3 million patients in the U.S. and is caused by cough reflex hypersensitivity in both the central and peripheral nerves. It is a highly debilitating disease and accompanied by a wide range of complications, ranging from urinary incontinence in females to sleep disruption and social embarrassment that causes significant social and economic burdens for patients and those around them.

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.
