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

NEW HAVEN, Conn., May 05, 2026 (GLOBE NEWSWIRE) -- 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), non-IPF interstitial lung disease (non-IPF ILD), and refractory chronic cough (RCC), today announced financial results for the quarter ended March 31, 2026, and provided business updates. 

“We are entering an important phase of execution for Trevi, with study initiations anticipated across our chronic cough programs,” said Jennifer Good, President and CEO of Trevi Therapeutics. “Following a very productive End-of-Phase 2 meeting with the FDA on our lead program in IPF-related chronic cough, we are excited to initiate multiple clinical trials this quarter, including our first Phase 3 in IPF-related chronic cough and our Phase 2b in RCC. With an expected cash runway into 2030, we are well-positioned to execute on our development strategy and advance towards a potential FDA submission in IPF-related chronic cough. We believe successful execution of our strategy would establish Trevi as the leader in providing best-in-class therapy in chronic cough indications with significant unmet needs and no FDA-approved therapies.”

Recent Business Highlights

IPF-Related Chronic Cough

• Completed an End-of-Phase 2 meeting with the FDA and gained overall alignment on the clinical development plan for the treatment of IPF-related chronic cough. Execution plans remain on track to conduct two Phase 3 trials in parallel with the first trial expected to initiate in the second quarter of 2026 and the second trial in the second half of 2026. The Company expects to have topline results from the first Phase 3 trial in the first half of 2028 and from the second Phase 3 trial in the second half of 2027.
• The Company received a notice to grant a European patent covering nalbuphine ER for the treatment of IPF-related chronic cough, with expected expiration in 2039, further strengthening its global intellectual property portfolio.
  
  

Non-IPF ILD-Related Chronic Cough

• The Company plans to initiate an adaptive design Phase 2b clinical trial for the treatment of patients with non-IPF ILD-related chronic cough in the second half of 2026, subject to a meeting with the FDA which includes review of the trial protocol. If the trial is initiated when anticipated, the Company would expect topline results from the Phase 2b trial in the second half of 2027.
  
  

Refractory Chronic Cough

• The Company plans to initiate a Phase 2b trial in patients with RCC in the second quarter of 2026, subject to final protocol review by regulatory authorities. The protocol will provide for a sample size re-estimation, or SSRE, analysis, which is expected to occur in the fourth quarter of 2026. The Company expects topline results from the trial in the second half of 2027.
  
  

Corporate

• In April 2026, the Company completed an underwritten common stock offering, resulting in net proceeds of approximately $162 million, after deducting underwriting discounts and commissions and estimated offering expenses.

First Quarter 2026 Financial Highlights   

Cash, cash equivalents and marketable securities: The Company ended the first quarter of 2026 with $171.8 million. After completion of its underwritten common stock offering in April 2026, the Company expects current cash resources to extend its cash runway into 2030.

The Company expects its current cash, cash equivalents and marketable securities to fund the development of Haduvio for the treatment of patients with IPF-related chronic cough, potentially through FDA approval. The Company also expects these cash resources will enable the Company to fund and report topline data from the planned Phase 2b clinical trial and potentially a subsequent Phase 3 trial for the treatment of patients with non-IPF ILD-related chronic cough, and the planned Phase 2b trial for the treatment of patients with RCC. The planned spending of these resources does not include any commercial expenses related to the commercial launch of Haduvio or any other clinical trials.

Research and development (R&D) expenses: R&D expenses for the first quarter of 2026 increased to $9.9 million from $7.8 million in the same period in 2025, primarily due to increased clinical development expenses for the Company's Phase 1 NDA supportive studies, Phase 3 IPF-related chronic cough trials and Phase 2b RCC trial, partially offset by a decrease in clinical development expenses for the Company's Phase 2b CORAL trial and Phase 2a RIVER trial.

General and administrative (G&A) expenses: G&A expenses for the first quarter of 2026 increased to $5.0 million from $3.7 million in the same period in 2025, primarily due to higher legal fees associated with intellectual property filings as well as an increase in non-cash stock option expense and other personnel-related expenses.

Other Income, net: Other Income, net for the first quarter of 2026 increased to $1.7 million from $1.1 million in the same period in 2025, primarily due to an increase in interest income from higher invested cash equivalent and marketable securities balances.

Net loss: For the first quarter of 2026, the Company reported a net loss of $13.2 million, compared to a net loss of $10.3 million in the same period in 2025.

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), non-IPF interstitial lung disease (non-IPF ILD), and refractory chronic cough (RCC). Haduvio is the first and only investigational therapy to show a statistically-significant reduction in cough frequency in clinical trials across both patients with IPF-related chronic cough and in patients with RCC. 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 in patients with IPF and non-IPF ILD is a condition with high unmet need and no FDA-approved therapies. There are ~140,000 U.S. patients with IPF, and two-thirds of these patients are faced with uncontrolled chronic cough. Additionally, there are ~228,000 U.S. patients with non-IPF ILD, with 50-60% having uncontrolled chronic cough. 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 a higher risk of morbidity and mortality, including worsening disease, a higher risk of progression, increased respiratory hospitalizations, and a decline in patients' quality of life.      
   
RCC is a condition with high unmet need and no FDA-approved therapies. RCC 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, upper airway cough syndrome, or post-nasal drip) and includes unexplained chronic cough. There are ~2-3 million U.S. patients with RCC, and it is believed to be associated with cough reflex hypersensitivity involving both the central and peripheral nervous systems. RCC is highly debilitating and may impact patients physically, psychologically, and socially.     

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.
