DUBLIN, Oct. 18, 2024 /PRNewswire/ -- Theravance Biopharma, Inc. ("Theravance Biopharma" or the "Company") (NASDAQ: TBPH) today announced the publication of a sub-study of the pivotal 12-week, randomized, registrational revefenacin Phase 3 trials (Trials 0126 [NCT02459080] and 0127 [NCT02512510]) for YUPELRI, the first and only FDA approved once-daily nebulized long-acting muscarinic antagonist (LAMA), evaluating the area under the curve (AUC) lung function effects in moderate-to-very-severe chronic obstructive pulmonary disease (COPD) patients. These data and analyses, published in the International Journal of Chronic Obstructive Pulmonary Disease, reinforce that YUPELRI provides consistent and durable improvements in lung function, as compared with placebo, over a full 24-hours. "Where previous data showed that revefenacin significantly improved peak and trough FEV1 at Day 85 compared with placebo in patients with moderate-to-very-severe COPD, this subset post-hoc analysis depicts a more comprehensive view of 24-hour bronchodilation as assessed by examining AUC over multiple time periods," said Dr. Donald A. Mahler, Emeritus Professor of Medicine at Geisel School of Medicine at Dartmouth in Hanover, NH and Pulmonologist and Respiratory Director at Valley Regional Hospital in Claremont, NH. "It provides additional valuable clinical insight into the duration and consistency of revefenacin over the entire dosing interval." Dr. Blake LeMaster, Assistant Professor of Medicine, Division of Allergy, Pulmonary and Critical Care Medicine, Vanderbilt University Medical Center, commented, "Importantly, this drug also exhibits a substantial peak response as well as bronchodilation over the initial 2-hour period as exhibited by FEV1 AUC 0-2H." He added, "Clinically meaningful bronchodilation was seen within the first 15 minutes of administration, persisting over the 24-hour duration during which patients underwent serial spirometry. These data demonstrate that revefenacin can provide rapid and prolonged bronchodilation with just a single dose." Key Study Findings: Analysis of a retrospective, pooled sub-study from Phase 3 Studies 0126 and 0127 demonstrated that revefenacin (n = 50) improved bronchodilation versus placebo (n = 47) in patients with moderate-to-very-severe COPD when assessed by FEV1 AUC. Rapid onset of bronchodilation was observed, with a mean FEV1 difference of 145 mL achieved at 15 minutes, exceeding the accepted Minimal Clinically Important Difference (MCID) of 100 mL with approximately 97.5% confidence. Day 84 bronchodilation improvements were sustained over 24 hours vs. placebo, with mean differences of 282 mL, 220 mL, 205 mL and 212 mL for FEV1 AUC0–2h, AUC0–12h, AUC12–24h and AUC0–24h, respectively, (p<0.001 for all). Trough FEV1 is an important endpoint often used in COPD trials and provides the magnitude of lung function benefit at the end of a given dosing interval. FEV1 AUC measurements provide additional information on the magnitude and consistency of bronchodilation throughout the dosing interval, including both daytime and nighttime effects. As patients depend on the magnitude of sustained bronchodilation to address COPD symptoms, combined use of both trough FEV1 and FEV1 AUC may allow for a more comprehensive assessment of bronchodilator efficacy to support clinical decision-making. About Studies 0126 and 0127 Studies 0126 (placebo, n = 209; 88 mcg revefenacin, n = 212; and 175 mcg revefenacin, n = 198), and 0127 (placebo, n = 208; 88 mcg revefenacin, n = 205; and 175 mcg revefenacin, n = 197) were replicate Phase 3 studies which included adults ≥40 years old with documented moderate-to-very-severe COPD, and a current or past smoking history of ≥10 pack-years. Subjects were randomized 1:1:1 to receive revefenacin 88 mcg, revefenacin 175 mcg, or placebo administered once-daily in the morning by a standard jet nebulizer (PARI LC Sprint) for 12 weeks. The prespecified primary efficacy endpoint was change from baseline in trough FEV1 on Day 85. Peak FEV1 on Day 1 was a secondary endpoint and FEV1 AUC from 0 to 2 hours (FEV1 AUC0–2h) on Days 1, 15, 29, 57, and 84 was a prespecified exploratory endpoint1. While both revefenacin 88 mcg and 175 mcg doses were investigated in these trials, the post hoc analysis reported herein focused only on the 175 mcg dose as this is the dose approved by the FDA2. About YUPELRI YUPELRI® (revefenacin) inhalation solution is the first and only once-daily nebulized long-acting muscarinic antagonist (LAMA) approved for the maintenance treatment of COPD in the U.S. LAMAs are recognized by international COPD treatment guidelines as a cornerstone of maintenance therapy for COPD.

Data support Ohtuvayre™ (ensifentrine), as a first-in-class, selective, dual inhibitor of PDE3 and PDE4 in a broad COPD populationLONDON and RALEIGH, N.C., Sept. 30, 2024 (GLOBE NEWSWIRE) -- Verona Pharma plc (Nasdaq: VRNA) (“Verona Pharma” or the “Company”) announces four oral presentations and two posters on analyses from its successful Phase 3 ENHANCE studies with Ohtuvayre (ensifentrine) for the treatment of chronic obstructive pulmonary disease (“COPD”) will be presented at CHEST Annual Meeting (“CHEST”) 2024. The analyses are published in the CHEST Annual Meeting on-line supplement. Ohtuvayre (ensifentrine) is a first-in-class selective dual inhibitor of the enzymes phosphodiesterase three and phosphodiesterase 4 (“PDE3 and PDE4”) that combines bronchodilator and non-steroidal anti-inflammatory effects in one molecule. Ohtuvayre is the first novel inhaled mechanism for the maintenance treatment of COPD in more than 20 years. The analyses will summarize the efficacy and safety of Ohtuvayre in subgroups of COPD patients including data supporting improvements in lung function, symptoms and quality of life, as well as reductions in the rate of exacerbations, regardless of COPD severity (moderate or severe), smoking status (current or former), and chronic bronchitis (with or without). Furthermore, an analysis of ensifentrine’s impact on reducing exacerbation rates and COPD-related healthcare resource utilization over 48 weeks will also be presented. “Ensifentrine is a remarkable addition to COPD therapy,” said William Stringer, MD, FCCP, Professor of Medicine in the David Geffen School of Medicine at UCLA. “It has the capacity to bronchodilate, reduce inflammation, augment mucociliary clearance, and reduce exacerbations in smokers and former smokers.” Details of Verona Pharma’s presentations and posters are listed below and linked to the CHEST website. In addition, the Company will present five presentations that will highlight the unmet need in COPD based on real world claims data.

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.
