NEW HAVEN, Conn., Nov. 6, 2024 /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) and refractory chronic cough (RCC), today announced financial results for the quarter ended September 30, 2024, as well as provided business updates.

"Our team has made excellent progress advancing our clinical programs this year, and we are eagerly anticipating the upcoming clinical results starting in December," said Jennifer Good, President and CEO of Trevi Therapeutics. "Positive results over the upcoming months would bring us closer to potentially addressing the significant unmet need and market opportunity in both chronic cough in IPF and RCC through Haduvio's unique mechanism."

Haduvio acts on the cough reflex arc both centrally and peripherally as a kappa agonist and a mu antagonist (KAMA), which are opioid receptors that play a key role in controlling cough hypersensitivity.

 Third Quarter and Recent Business Highlights

• Completed enrollment in the Phase 2a RIVER trial for the treatment of RCC in October 2024. The Company expects topline data in the first quarter of 2025.
• Enrolled 50% of the planned 160 patients in the Phase 2b CORAL trial for the treatment of chronic cough in patients with IPF as of October 2024. The Company expects to release the sample size re-estimation (SSRE) outcome in December 2024. Topline results are expected in the first half of 2025, assuming no adjustments are made to the sample size as a result of the SSRE.
• Completed dosing in the Human Abuse Potential (HAP) study in the third quarter of 2024, with topline results expected in December 2024.
• Announced during the third quarter the appointment of James V. Cassella, Ph.D., as Chief Development Officer.

Third Quarter 2024 Financial Highlights 

Research and development (R&D) expenses: R&D expenses for the third quarter of 2024 increased to $11.2 million from $6.3 million in the same period in 2023, primarily due to increased clinical development expenses for the Phase 2b CORAL trial, the Phase 2a RIVER trial, and the HAP study, as well as an increase in personnel related expenses.

General and administrative (G&A) expenses: G&A expenses for the third quarter of 2024 increased to $2.9 million from $2.7 million in the same period in 2023, primarily due to an increase in stock-based compensation expense.

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

Chronic cough is highly prevalent among approximately 140,000 IPF patients in the U.S., with up to 85% of IPF patients experiencing chronic cough. The impact of chronic cough is significant with IPF patients coughing up to 1,500 times per day and 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 IPF and current treatment options provide minimal benefit to patients.

Refractory chronic cough affects approximately 2-3 million adults in the U.S. and is caused by cough reflex hypersensitivity in both the central and peripheral nerves. It is highly disruptive 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. Haduvio is being developed for the treatment of moderate to severe RCC. There are also no approved therapies for RCC in the U.S. 

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.
