Persistent cough

Topline results are expected in the first quarter of 2025 NEW HAVEN, Conn., Oct. 21, 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 that it has completed enrollment in its Phase 2a trial for the treatment of RCC ("RIVER") and expects to report topline data in the first quarter of 2025. "We are happy to have completed enrollment for our Phase 2a RIVER trial for the treatment of RCC," said Jennifer Good, President and CEO of Trevi Therapeutics. "RCC impacts approximately 2-3 million adults in the U.S. and with no approved treatment options, there is a large unmet need for new therapies that address cough hypersensitivity. We look forward to reporting the topline results for RIVER early next year and building on the positive results we have seen in studying chronic cough in IPF." Phase 2a Trial Design: Refractory Chronic Cough Improvement Via Nal ER (RIVER) The Phase 2a RIVER trial is a randomized, double-blind, placebo-controlled, two-treatment, two-period, crossover study designed to evaluate the efficacy, safety, tolerability and dosing of Haduvio for the treatment of RCC. The trial is being conducted at multiple sites in the United Kingdom and Canada. The primary endpoint of the trial is a mean change in 24-hour cough frequency in the overall population as determined using an objective cough monitor. Based on the screening results, the study will enroll patients into one of two subgroups: 10-19 coughs/hour (moderate 24-hour cough frequency) and ≥20 coughs/hour (high 24-hour cough frequency). The trial will also explore secondary endpoints, including patient-reported outcome measures for cough frequency and severity. The trial was designed to enroll approximately 60 adult patients. About Refractory Chronic Cough (RCC) 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) or where no underlying condition exists. 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 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. 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 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 scheduled by the U.S. Drug Enforcement Agency. 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 benefit to patients. Chronic cough 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 refractory chronic cough. 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. For more information, visit and follow Trevi on X (formerly Twitter) and LinkedIn.

Sanofi and Regeneron’s Dupixent (dupilumab) has been approved by the US Food and Drug Administration (FDA) as an add-on maintenance treatment for chronic obstructive pulmonary disease (COPD). The regulator’s decision, which makes Dupixent the first biologic medicines approved in the US for COPD, specifically applies to adults with inadequately controlled cases of the condition and an eosinophilic phenotype. COPD is a chronic respiratory disease that causes progressive lung function decline and results in symptoms such as persistent cough, excessive mucus production and a shortness of breath. Sanofi and Regeneron have outlined that there are approximately 300,000 patients in the US who will be eligible for treatment with Dupixent, a fully human monoclonal antibody that inhibits the signalling of the interleukin-4 and interleukin-13 pathways shown to be central drivers of the type 2 inflammation that plays a major role in multiple related diseases. The approval was based on positive results from the late-stage BOREAS and NOTUS trials of the therapy in adults with uncontrolled COPD and blood eosinophils of at least 300 cells per μL. All patients were on maximal standard-of-care inhaled therapy and nearly all were receiving triple therapy. The primary endpoint was met in both studies, with Dupixent demonstrating a 30% and 34% reduction in annualised moderate or severe COPD exacerbations compared to placebo over 52 weeks in BOREAS and NOTUS, respectively. Improvements in lung function in Dupixent-treated patients were sustained at 52 weeks, and the therapy was also associated with greater improvements in health-related quality of life compared to placebo at one year, as assessed by a four-point improvement on the St George’s Respiratory Questionnaire. Dupixent was recently approved in the UK, EU and China for uncontrolled COPD, with submissions currently under review with other regulatory authorities globally. Rippon Ubhi, country lead, Sanofi UK and Ireland, said: “This approval represents a significant shift in the longstanding treatment landscape for COPD patients. It marks the first time in more than a decade that we’ve seen a meaningful change in the treatments available to physicians to combat this devastating disease. Respiratory illnesses are the third biggest cause of death in the UK behind cancer and cardiovascular disease. Over 20,000 people with COPD die every year in the UK. “[Dupixent] has been clinically shown to reduce COPD exacerbations and improve lung function, and it is our priority to work with regulatory bodies to ensure patients in the UK can access this important treatment option as soon as possible.”

PARIS, France and TARRYTOWN, NY, USA I September 27, 2024 I The US Food and Drug Administration (FDA) has approved Dupixent (dupilumab) as an add-on maintenance treatment of adults with inadequately controlled chronic obstructive pulmonary disease (COPD) and an eosinophilic phenotype. Dupixent is the first biologic medicine approved in the US to treat these patients. Jean Wright, M.D. Chief Executive Officer at The COPD Foundation “People living with inadequately controlled COPD have long awaited new medicines to help manage the daily suffering they experience from breathlessness, coughing, wheezing, exhaustion and unpredictable hospitalization. These patients often struggle with everyday activities many people take for granted such as taking a walk or running errands outside the home. We welcome the approval of this new therapeutic option to offer patients a new way to help gain better control of their disease.” Paul Hudson Chief Executive Officer at Sanofi “Dupixent has already shown it can revolutionize the treatment paradigm of many diseases driven in part by type 2 inflammation with high unmet medical needs, with one million patients being treated globally across all currently approved indications. With today’s approval, Dupixent once again paves the way and becomes the first and only approved add-on biologic medicine for inadequately controlled COPD, giving patients living with this devastating disease the chance to look forward to the potential of improved breathing and a life with fewer exacerbations.” The FDA approval is based on data from two landmark pivotal phase 3 studies ( BOREAS and NOTUS ) that evaluated the efficacy and safety of Dupixent compared to placebo in adults currently on maximal standard-of-care inhaled therapy (nearly all on triple therapy) with inadequately controlled COPD and blood eosinophils ≥300 cells per μL. Patients who received Dupixent in BOREAS (n=468) and NOTUS (n=470) experienced the following outcomes, respectively, compared to placebo (BOREAS n=471; NOTUS n=465): Safety results in both studies were generally consistent with the known safety profile of Dupixent in its approved indications. In pooled BOREAS and NOTUS data, the most common adverse events (>2%) more frequently observed in patients on Dupixent compared to placebo were viral infection, headache, nasopharyngitis, back pain, diarrhea, arthralgia, urinary tract infection, local administration reaction, rhinitis, eosinophilia, toothache, and gastritis. While less common, cholecystitis was reported in 0.6% of patients on Dupixent compared to 0.1% of patients on placebo. George D. Yancopoulos, M.D., Ph.D. Board Co-Chair, President and Chief Scientific Officer at Regeneron “This latest FDA approval for Dupixent represents new hope for the hundreds of thousands of COPD patients in the US who can sometimes struggle just to breathe during their everyday lives. Dupixent has a proven track record as a first-in-class medicine, providing benefit to the many patients suffering from type 2 inflammatory related diseases such as asthma and atopic dermatitis. This latest approval represents an important next chapter for Dupixent, giving those with COPD a novel option that has demonstrated the unprecedented ability to help patients experience fewer exacerbations, while also helping them breathe better and improve quality of life in phase 3 studies.” The FDA evaluated Dupixent under Priority Review, which is reserved for medicines that represent potentially significant improvements in efficacy or safety in treating serious conditions. In July 2024, Sanofi and Regeneron announced that the European Medicines Agency approved Dupixent as an add-on maintenance treatment for adults with uncontrolled COPD characterized by raised blood eosinophils. Submissions are currently under review with other regulatory authorities around the world, including in Japan. About COPD COPD is a respiratory disease that damages the lungs and causes progressive lung function decline and is the fourth leading cause of death worldwide. Symptoms include persistent cough, excessive mucus production and shortness of breath that may impair the ability to perform routine daily activities, which may lead to sleep disturbances, anxiety, and depression. COPD is also associated with a significant health and economic burden due to recurrent acute exacerbations that require systemic corticosteroid medicine and/or antibiotics. Smoking and exposure to noxious particles are key risk factors for COPD, but even individuals who quit smoking can still have progressive lung disease. About half of COPD patients continue to experience exacerbations despite being on triple inhaled therapy. In the US, approximately 300,000 people live with inadequately controlled COPD and an eosinophilic phenotype. Patients with an eosinophilic phenotype contribute to an ~30% increase in exacerbations and an increased risk of COPD-related re-hospitalizations within a year. About the Dupixent COPD phase 3 study program BOREAS and NOTUS were replicate, randomized, phase 3, double-blind, placebo-controlled studies that evaluated the efficacy and safety of Dupixent in adults who were current or former smokers with moderate-to-severe COPD with an eosinophilic phenotype, as defined by blood eosinophils ≥300 cells per µL. The studies included adults with COPD across a broad range of clinical presentations, including those with chronic bronchitis and emphysema. The studies enrolled 1,874 patients who were aged 40 to 80 years in BOREAS and 40 to 85 years in NOTUS. During the 52-week treatment period, patients in BOREAS and NOTUS received Dupixent or placebo every two weeks added to a maximal standard-of-care inhaled triple therapy of ICS, LABA and LAMA. Double maintenance therapy, which included LABA and LAMA, was allowed if ICS was not appropriate. The primary endpoint for BOREAS and NOTUS evaluated the annualized rate of acute moderate or severe COPD exacerbations. Key secondary endpoints included change from baseline in lung function (assessed by pre-bronchodilator forced expiratory volume [FEV 1 ]) at 12 and 52 weeks, change from baseline at 52 weeks in SGRQ total score compared to placebo, and safety. The results of both BOREAS and NOTUS were separately published in The New England Journal of Medicine . About Sanofi and Regeneron’s COPD Clinical Research Program Sanofi and Regeneron are motivated to transform the treatment paradigm of COPD by examining the role different types of inflammation play in the disease progression through Dupixent, a first-in-class biologic, and the investigation of itepekimab. Dupixent inhibits the signaling of the interleukin-4 (IL4) and interleukin-13 (IL13) pathways and the program focuses on a specific population of people with evidence of type 2 inflammation. Itepekimab is a fully human monoclonal antibody that binds to and inhibits interleukin-33 (IL33), an initiator and amplifier of broad inflammation in COPD. Itepekimab is currently under clinical investigation for COPD in two phase 3 studies and its safety and efficacy have not been evaluated by any regulatory authority. About Dupixent Dupixent is a fully human monoclonal antibody that inhibits the signaling of the IL4 and IL13 pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in phase 3 studies, establishing that IL4 and IL13 are two of the key and central drivers of type 2 inflammation that play a major role in multiple related and often co-morbid diseases. Sanofi and Regeneron are committed to helping patients in the US who are prescribed Dupixent gain access to the medicine and receive the support they may need with the DUPIXENT MyWay ® program. For more information, please call 1-844-DUPIXENT (1-844-387-4936) or visit www.DUPIXENT.com . Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, prurigo nodularis, chronic spontaneous urticaria, and COPD in different age populations. More than 1,000,000 patients are being treated with Dupixent globally. Dupilumab Development Program Dupilumab is being jointly developed by Sanofi and Regeneron under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical studies involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation. In addition to the currently approved indications, Sanofi and Regeneron are studying dupilumab in a broad range of diseases driven in part by type 2 inflammation or other allergic processes in phase 3 studies, including chronic pruritus of unknown origin and bullous pemphigoid. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority.
