At the meeting, the Company gained overall alignment on the plan for the remaining development program. The Company plans to conduct two pivotal Phase 3 clinical trials and obtained agreement on the remaining Phase 1 clinical studies that the Company expects to conduct to support the New Drug Application (NDA) submission. The Company plans to conduct the Phase 3 trials in parallel with each other and is on track to initiate the first Phase 3 trial in the second quarter of 2026 and the second Phase 3 trial in the second half of 2026.<\/p>\n<p>\u201cWe very much appreciate the FDA\u2019s careful review of our IPF-related chronic cough program to date and the highly collaborative discussions we had during the meeting,\u201d said\u00a0James Cassella, PhD, Chief Development Officer of Trevi Therapeutics. \u201cWe clarified the path forward for our Phase 3 program and received useful guidance on the remaining Phase 1 studies to be conducted. We are well positioned to initiate pivotal parallel Phase 3 trials beginning in the second quarter of 2026 and to execute on the remaining development program.\u201d<\/p>\n<p>Jennifer Good, President and CEO of Trevi Therapeutics, added, \u201cThe End-of-Phase 2 meeting was an important milestone for the Company, and we are grateful for the guidance from the FDA. With no FDA-approved therapies for IPF-related chronic cough, it remains highly burdensome for patients living with IPF and is a condition which has historically had limited options. Our team is focused on advancing Haduvio for these patients and potentially addressing this urgent unmet need.\u201d<\/p>\n<p>The Phase 3 trials will both be randomized, double-blind, placebo-controlled, multicenter, global trials evaluating the safety and efficacy of nalbuphine ER tablets, with 54 mg twice-a-day (BID) dosing, for the treatment of patients with IPF-related chronic cough. Patients enrolled in the trials will be randomized 2:1 to either nalbuphine ER or placebo. The first of the two Phase 3 trials is planned to enroll approximately 300 patients with IPF-related chronic cough and have 52 weeks of fixed dosing, with the primary endpoint at 24 weeks of fixed dosing. The other Phase 3 trial is planned to enroll approximately 130 patients with IPF-related chronic cough and have 12 weeks of fixed dosing. The primary efficacy endpoint for both trials will be the relative change from Baseline in 24-hour cough frequency (coughs per hour), as determined by an objective cough monitor, for nalbuphine ER compared with placebo. These trial designs are subject to final review of the protocols by the FDA.<\/p>\n<p>\n        <strong>About Idiopathic Pulmonary Fibrosis (IPF)-Related Chronic Cough<\/strong><br \/>\n        <br \/>Chronic cough in patients with IPF is a condition with high unmet need and no FDA-approved therapies. There are ~150,000 U.S. patients with IPF, and two-thirds of these patients are faced with 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&#8217; quality of life.<\/p>\n<p>\n        <strong>About Trevi Therapeutics, Inc.<\/strong><br \/>\n        <br \/>Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio\u2122 (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 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.<\/p>\n<p>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.\u00a0<\/p>\n<p>For more information, visit\u00a0<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=H6PthOTs7W_fmDI8nYuXBNW0hsl7j7HbsnEWBXad5CBqTzy7N9ZHsTa2rYebo9v0-mUcbaOVxhckmpg09NLSQHKMBdveLoCiuXk_T_kp0M9XfFG2yBTpBu83zlv6bf0g\" rel=\"nofollow\" target=\"_blank\">www.TreviTherapeutics.com<\/a> and follow Trevi on\u00a0<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=xzjnQ7TvOA1tsZIFexazaobc4mYTcI2Isjdt4eMf7Al-zL6mTO7kFbtumOv0JsUtaTb6X-XIpqSOVEXlXG9gfA==\" rel=\"nofollow\" target=\"_blank\">X<\/a>\u00a0(formerly Twitter) and\u00a0<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=44ZrRGDBnFYHebiwu2M8wut26NKpfGVrJjKvyJk87Ebp_9XE_VK_paSlL7bbQhs1DkPcQhmPRHH3NyXji-sWCxig0zxR4sAKdZWDupyFFGQ-yhVZ4xhqAxaOKg6M8tDY\" rel=\"nofollow\" target=\"_blank\">LinkedIn<\/a>.\u00a0<\/p>\n<p>\n        <strong>Forward-Looking Statements<\/strong><br \/>\n        <br \/>Statements contained in this press release regarding matters that are not historical facts are &#8220;forward-looking statements&#8221; within the meaning of the Private Securities Litigation Reform Act of 1995.
