Expanded savings programs build on company’s longstanding commitment to addressing barriers to access and affordability for patients WILMINGTON, Del.--(BUSINESS WIRE)-- AstraZeneca announced it will expand the savings programs for its entire US inhaled respiratory portfolio, helping eligible patients pay no more than $35 per month for their medicine.* Expanding the savings programs will help make its inhalers more affordable to the most vulnerable patients living with asthma and chronic obstructive pulmonary disease (COPD), including those who are uninsured and underinsured. Pascal Soriot, Chief Executive Officer, AstraZeneca, said: “AstraZeneca’s expanded savings programs build on our longstanding commitment to addressing barriers to access and affordability for patients living with respiratory diseases to ultimately help patients lead healthier lives. We remain dedicated to addressing the need for affordability of our medicines, but the system is complex and we cannot do it alone. It is critical that Congress bring together key stakeholders to help reform the healthcare system so patients can afford the medicines they need, not just today, but for the future.” Starting June 1, 2024, eligible patients will pay no more than $35 per month for all AstraZeneca US inhaled respiratory medicines, including: AIRSUPRA® (albuterol and budesonide) BEVESPI AEROSPHERE® (glycopyrrolate and formoterol fumarate) Inhalation Aerosol BREZTRI AEROSPHERE® (budesonide, glycopyrrolate, and formoterol fumarate) Inhalation Aerosol SYMBICORT® (budesonide and formoterol fumarate dihydrate) Inhalation Aerosol In addition, AstraZeneca substantially reduced the list price of SYMBICORT on January 1, 2024. The Company will continue to provide discounts and rebates off the list price to help patients afford its inhaled respiratory medicines. For more than 50 years, AstraZeneca has served respiratory patients by investing in the research and development of new drug-device combinations, as well as next-generation biologics and novel mechanisms to address the vast unmet needs of these chronic, often debilitating diseases. AstraZeneca remains dedicated to transforming patient outcomes, while ensuring access and affordability of our innovative medicines. *Terms and conditions apply. Government restrictions exclude people enrolled in federal government insurance programs from co-pay support. IMPORTANT SAFETY INFORMATION AIRSUPRA® (albuterol and budesonide) Contraindications: Hypersensitivity to albuterol, budesonide, or to any of the excipients Deterioration of Asthma: Asthma may deteriorate acutely over a period of hours or chronically over several days or longer. If the patient continues to experience symptoms after using AIRSUPRA or requires more doses of AIRSUPRA than usual, it may be a marker of destabilization of asthma and requires evaluation of the patient and their treatment regimen Paradoxical Bronchospasm: AIRSUPRA can produce paradoxical bronchospasm, which may be life threatening. Discontinue AIRSUPRA immediately and institute alternative therapy if paradoxical bronchospasm occurs. It should be recognized that paradoxical bronchospasm, when associated with inhaled formulations, frequently occurs with the first use of a new canister Cardiovascular Effects: AIRSUPRA, like other drugs containing beta2-adrenergic agonists, can produce clinically significant cardiovascular effects in some patients, as measured by pulse rate, blood pressure, and/or other symptoms. If such effects occur, AIRSUPRA may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the T wave, prolongation of the QTc interval, and ST-segment depression. Therefore, AIRSUPRA, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension Do Not Exceed Recommended Dose: Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs Hypersensitivity Reactions, Including Anaphylaxis: Can occur after administration of albuterol sulfate and budesonide, components of AIRSUPRA, as demonstrated by cases of anaphylaxis, angioedema, bronchospasm, oropharyngeal edema, rash, and urticaria. Discontinue AIRSUPRA if such reactions occur Risk of Sympathomimetic Amines with Certain Coexisting Conditions: AIRSUPRA, like all therapies containing sympathomimetic amines, should be used with caution in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus and in patients who are unusually responsive to sympathomimetic amines Hypokalemia: Beta-adrenergic agonist medicines may produce significant hypokalemia in some patients. The decrease in serum potassium is usually transient, not requiring supplementation Immunosuppression and Risk of Infections: Due to possible immunosuppression from the use of inhaled corticosteroids (ICS), potential worsening of infections could occur. Use with caution. A more serious or fatal course of chickenpox or measles can occur in susceptible patients Oropharyngeal Candidiasis: Has occurred in patients treated with ICS agents. Monitor patients periodically. Advise patients to rinse his/her mouth with water, if available, without swallowing after inhalation Hypercorticism and Adrenal Suppression: May occur with very high doses in susceptible individuals. If such changes occur, consider appropriate therapy Reduction in Bone Mineral Density: Decreases in bone mineral density have been observed with long-term administration of ICS. For patients at high risk for decreased bone mineral density, assess initially and periodically thereafter Glaucoma and Cataracts: Have been reported following the long-term administration of ICS, including budesonide, a component of AIRSUPRA Effects on Growth: Orally inhaled corticosteroids, including budesonide, may cause a reduction in growth velocity when administered to pediatric patients. The safety and effectiveness of AIRSUPRA have not been established in pediatric patients, and AIRSUPRA is not indicated for use in this population Most common adverse reactions (incidence ≥ 1%) are headache, oral candidiasis, cough, and dysphonia Drug Interactions: AIRSUPRA should be administered with caution to patients being treated with: Strong cytochrome P450 3A4 inhibitors (may cause systemic corticosteroid effects) Short-acting bronchodilators (concomitant use of additional beta-agonists with AIRSUPRA should be used judiciously to prevent beta-agonist overdose) Beta-blockers (may block pulmonary effects of beta-agonists and produce severe bronchospasm) Diuretics or non-potassium-sparing diuretics (may potentiate hypokalemia or ECG changes). Consider monitoring potassium levels Digoxin (may decrease serum digoxin levels). Consider monitoring digoxin levels Monoamine oxidase inhibitors (MAOI) or tricyclic antidepressants (Use AIRSUPRA with extreme caution; may potentiate effect of albuterol on the cardiovascular system) Use AIRSUPRA with caution in patients with hepatic impairment, as budesonide systemic exposure may increase. Monitor patients with hepatic disease Please see full Prescribing Information, including Patient Information. You may report side effects related to AstraZeneca products. BEVESPI AEROSPHERE® (glycopyrrolate and formoterol fumarate) Inhalation Aerosol CONTRAINDICATIONS All long-acting beta2-adrenergic agonists (LABAs), including formoterol fumarate, are contraindicated in patients with asthma without use of an inhaled corticosteroid. BEVESPI is not indicated for the treatment of asthma. BEVESPI is contraindicated in patients with hypersensitivity to glycopyrrolate, formoterol fumarate, or to any component of the product. WARNINGS AND PRECAUTIONS The safety and efficacy of BEVESPI AEROSPHERE in patients with asthma have not been established. BEVESPI AEROSPHERE is not indicated for the treatment of asthma Use of LABAs as monotherapy (without inhaled corticosteroids [ICS]) for asthma is associated with an increased risk of asthma-related death. These findings are considered a class effect of LABA monotherapy. When LABAs are used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared to ICS alone. Available data do not suggest an increased risk of death with use of LABAs in patients with chronic obstructive pulmonary disease (COPD) BEVESPI should not be initiated in patients with acutely deteriorating COPD, which may be a life-threatening condition BEVESPI should not be used for the relief of acute symptoms (ie, as rescue therapy for the treatment of acute episodes of bronchospasm). Acute symptoms should be treated with an inhaled short-acting beta2-agonist (SABA) BEVESPI should not be used more often or at higher doses than recommended, or with other LABAs, as an overdose may result If paradoxical bronchospasm occurs, discontinue BEVESPI immediately and institute alternative therapy If immediate hypersensitivity reactions occur, in particular, angioedema, urticaria, or skin rash, discontinue BEVESPI at once and consider alternative treatment BEVESPI can produce a clinically significant cardiovascular effect in some patients, as measured by increases in pulse rate, blood pressure, or symptoms. If such effects occur, BEVESPI may need to be discontinued Use with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, ketoacidosis, and in patients who are unusually responsive to sympathomimetic amines Be alert to hypokalemia and hyperglycemia Worsening of narrow-angle glaucoma or urinary retention may occur. Use with caution in patients with narrow-angle glaucoma, prostatic hyperplasia, or bladder-neck obstruction, and instruct patients to contact a physician immediately if symptoms occur ADVERSE REACTIONS The most common adverse reactions with BEVESPI (≥2% and more common than placebo) were cough, 4.0% (2.7%) and urinary tract infection, 2.6% (2.3%). DRUG INTERACTIONS Use caution if administering additional adrenergic drugs because the sympathetic effects of formoterol may be potentiated Concomitant treatment with xanthine derivatives, steroids, or diuretics may potentiate any hypokalemic effect of formoterol Use with caution in patients taking non-potassium-sparing diuretics, as the ECG changes and/or hypokalemia may worsen with concomitant beta2-agonists The action of adrenergic agonists on the cardiovascular system may be potentiated by monoamine oxidase inhibitors, tricyclic antidepressants, or other drugs known to prolong the QTc interval. Therefore, BEVESPI should be used with extreme caution in patients being treated with these agents Use beta-blockers with caution as they not only block the therapeutic effects of beta-agonists, but may produce severe bronchospasm in patients with COPD Avoid co-administration of BEVESPI with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic adverse effects INDICATION BEVESPI AEROSPHERE is a combination of glycopyrrolate, an anticholinergic, and formoterol fumarate, a long-acting beta2-adrenergic agonist (LABA), indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema. LIMITATION OF USE Not indicated for the relief of acute bronchospasm or for the treatment of asthma. Please read full Prescribing Information, including Patient Information. You may report side effects related to AstraZeneca products. BREZTRI AEROSPHERE® (budesonide, glycopyrrolate, and formoterol fumarate) Inhalation Aerosol BREZTRI is contraindicated in patients who have a hypersensitivity to budesonide, glycopyrrolate, formoterol fumarate, or product excipients BREZTRI is not indicated for treatment of asthma. Long-acting beta2-adrenergic agonist (LABA) monotherapy for asthma is associated with an increased risk of asthma-related death. These findings are considered a class effect of LABA monotherapy. When a LABA is used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone. Available data do not suggest an increased risk of death with use of LABA in patients with COPD BREZTRI should not be initiated in patients with acutely deteriorating COPD, which may be a life-threatening condition BREZTRI is NOT a rescue inhaler. Do NOT use to relieve acute symptoms; treat with an inhaled short-acting beta2-agonist BREZTRI should not be used more often than recommended; at higher doses than recommended; or in combination with LABA-containing medicines, due to risk of overdose. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs Oropharyngeal candidiasis has occurred in patients treated with orally inhaled drug products containing budesonide. Advise patients to rinse their mouths with water without swallowing after inhalation Lower respiratory tract infections, including pneumonia, have been reported following ICS. Physicians should remain vigilant for the possible development of pneumonia in patients with COPD as the clinical features of pneumonia and exacerbations frequently overlap Due to possible immunosuppression, potential worsening of infections could occur. Use with caution. A more serious or fatal course of chickenpox or measles can occur in susceptible patients Particular care is needed for patients transferred from systemic corticosteroids to ICS because deaths due to adrenal insufficiency have occurred in patients during and after transfer. Taper patients slowly from systemic corticosteroids if transferring to BREZTRI Hypercorticism and adrenal suppression may occur with regular or very high dosage in susceptible individuals. If such changes occur, consider appropriate therapy Caution should be exercised when considering the coadministration of BREZTRI with long-term ketoconazole and other known strong CYP3A4 Inhibitors. Adverse effects related to increased systemic exposure to budesonide may occur If paradoxical bronchospasm occurs, discontinue BREZTRI immediately and institute alternative therapy Anaphylaxis and other hypersensitivity reactions (eg, angioedema, urticaria or rash) have been reported. Discontinue and consider alternative therapy Use caution in patients with cardiovascular disorders, especially coronary insufficiency, as formoterol fumarate can produce a clinically significant cardiovascular effect in some patients as measured by increases in pulse rate, systolic or diastolic blood pressure, and also cardiac arrhythmias, such as supraventricular tachycardia and extrasystoles Decreases in bone mineral density have been observed with long-term administration of ICS. Assess initially and periodically thereafter in patients at high risk for decreased bone mineral content Glaucoma and cataracts may occur with long-term use of ICS. Worsening of narrow-angle glaucoma may occur, so use with caution. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use BREZTRI long term. Instruct patients to contact a healthcare provider immediately if symptoms occur Worsening of urinary retention may occur. Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction. Instruct patients to contact a healthcare provider immediately if symptoms occur Use caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, and ketoacidosis or unusually responsive to sympathomimetic amines Be alert to hypokalemia or hyperglycemia Most common adverse reactions in a 52-week trial (incidence ≥ 2%) were upper respiratory tract infection (5.7%), pneumonia (4.6%), back pain (3.1%), oral candidiasis (3.0%), influenza (2.9%), muscle spasms (2.8%), urinary tract infection (2.7%), cough (2.7%), sinusitis (2.6%), and diarrhea (2.1%). In a 24-week trial, adverse reactions (incidence ≥ 2%) were dysphonia (3.3%) and muscle spasms (3.3%) BREZTRI should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors and tricyclic antidepressants, as these may potentiate the effect of formoterol fumarate on the cardiovascular system BREZTRI should be administered with caution to patients being treated with: Strong cytochrome P450 3A4 inhibitors (may cause systemic corticosteroid effects) Adrenergic drugs (may potentiate effects of formoterol fumarate) Xanthine derivatives, steroids, or non-potassium sparing diuretics (may potentiate hypokalemia and/or ECG changes) Beta-blockers (may block bronchodilatory effects of beta-agonists and produce severe bronchospasm) Anticholinergic-containing drugs (may interact additively). Avoid use with BREZTRI Use BREZTRI with caution in patients with hepatic impairment, as budesonide and formoterol fumarate systemic exposure may increase. Patients with severe hepatic disease should be closely monitored INDICATION BREZTRI AEROSPHERE is indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). LIMITATIONS OF USE Not indicated for the relief of acute bronchospasm or for the treatment of asthma. Please see full BREZTRI Prescribing Information, including Patient Information. You may report side effects related to AstraZeneca products. SYMBICORT® (budesonide and formoterol fumarate dihydrate) Inhalation Aerosol Use of long-acting beta2-adrenergic agonists (LABA) as monotherapy (without inhaled corticosteroids [ICS]) for asthma is associated with an increased risk of asthma-related death. Available data from controlled clinical trials also suggest that use of LABA as monotherapy increases the risk of asthma-related hospitalization in pediatric and adolescent patients. These findings are considered a class effect of LABA. When LABA are used in fixed dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared to ICS alone SYMBICORT is NOT a rescue medication and does NOT replace fast-acting inhalers to treat acute symptoms SYMBICORT should not be initiated in patients during rapidly deteriorating episodes of asthma or COPD Patients who are receiving SYMBICORT should not use additional formoterol or other LABA for any reason Localized infections of the mouth and pharynx with Candida albicans has occurred in patients treated with SYMBICORT. Patients should rinse the mouth after inhalation of SYMBICORT Lower respiratory tract infections, including pneumonia, have been reported following the administration of ICS Due to possible immunosuppression, potential worsening of infections could occur. A more serious or even fatal course of chickenpox or measles can occur in susceptible patients It is possible that systemic corticosteroid effects such as hypercorticism and adrenal suppression may occur, particularly at higher doses. Particular care is needed for patients who are transferred from systemically active corticosteroids to ICS. Deaths due to adrenal insufficiency have occurred in asthmatic patients during and after transfer from systemic corticosteroids to less systemically available ICS Caution should be exercised when considering administration of SYMBICORT in patients on long-term ketoconazole and other known potent CYP3A4 inhibitors As with other inhaled medications, paradoxical bronchospasm may occur with SYMBICORT Immediate hypersensitivity reactions may occur, as demonstrated by cases of urticaria, angioedema, rash, and bronchospasm Excessive beta-adrenergic stimulation has been associated with central nervous system and cardiovascular effects. SYMBICORT should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension Long-term use of ICS may result in a decrease in bone mineral density (BMD). Since patients with COPD often have multiple risk factors for reduced BMD, assessment of BMD is recommended prior to initiating SYMBICORT and periodically thereafter ICS may result in a reduction in growth velocity when administered to pediatric patients Glaucoma, increased intraocular pressure, and cataracts have been reported following the administration of ICS, including budesonide, a component of SYMBICORT. Close monitoring is warranted in patients with a change in vision or history of increased intraocular pressure, glaucoma, or cataracts In rare cases, patients on ICS may present with systemic eosinophilic conditions SYMBICORT should be used with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, ketoacidosis, and in patients who are unusually responsive to sympathomimetic amines Beta-adrenergic agonist medications may produce hypokalemia and hyperglycemia in some patients The most common adverse reactions ≥3% reported in asthma clinical trials included nasopharyngitis, headache, upper respiratory tract infection, pharyngolaryngeal pain, sinusitis, pharyngitis, rhinitis, influenza, back pain, nasal congestion, stomach discomfort, vomiting, and oral candidiasis The most common adverse reactions ≥3% reported in COPD clinical trials included nasopharyngitis, oral candidiasis, bronchitis, sinusitis, and upper respiratory tract infection SYMBICORT should be administered with caution to patients being treated with MAO inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents Beta-blockers may not only block the pulmonary effect of beta-agonists, such as formoterol, but may produce severe bronchospasm in patients with asthma ECG changes and/or hypokalemia associated with nonpotassium-sparing diuretics may worsen with concomitant beta-agonists. Use caution with the coadministration of SYMBICORT INDICATIONS SYMBICORT is indicated for the treatment of asthma in patients 6 years and older not adequately controlled on a long-term asthma-control medication such as an ICS or whose disease warrants initiation of treatment with both an ICS and LABA (also see DOSAGE AND ADMINISTRATION). SYMBICORT 160/4.5 is indicated for the maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema, and to reduce COPD exacerbations. SYMBICORT is NOT indicated for the relief of acute bronchospasm. Please see full Prescribing Information, including Patient Information. You may report side effects related to AstraZeneca products. Notes About Asthma Asthma is a chronic, inflammatory respiratory disease with variable symptoms that affects as many as 262 million people worldwide,1 including approximately 25 million in the US.2 Patients with asthma experience recurrent breathlessness and wheezing, which varies over time, and in severity and frequency.3 These patients are at risk of severe exacerbations regardless of their disease severity, adherence to treatment or level of control.4-5 There are an estimated 136 million asthma exacerbations globally per year,6 including approximately 10 million in the US2; these are physically threatening and emotionally significant for many patients7 and can be fatal.3,8 Inflammation is central to both asthma symptoms4 and exacerbations.9 Many patients experiencing asthma symptoms use a SABA (e.g., albuterol) as a rescue medicine10-12; however, taking a SABA alone does not address inflammation, leaving patients at risk of severe exacerbations,13 which can result in impaired quality of life,14 hospitalization15 and frequent oral corticosteroid (OCS) use.15 Treatment of exacerbations with as few as 1-3 short courses of OCS are associated with an increased risk of adverse health conditions including type 2 diabetes, depression/anxiety, renal impairment, cataracts, cardiovascular disease, pneumonia and fracture.16 International recommendations from the GINA no longer recommend SABA alone as the preferred rescue therapy.3 About COPD COPD refers to a group of lung diseases, including chronic bronchitis and emphysema, that cause airflow blockage and breathing-related problems.17 Affecting an estimated 16 million Americans, COPD is the third leading cause of death due to chronic disease and the sixth overall leading cause of death in the US.18-19 About AIRSUPRA® AIRSUPRA (albuterol and budesonide), formerly known as PT027, is a first-in-class SABA/ICS rescue treatment for asthma in the US, to be taken as needed. It is an inhaled, fixed-dose combination rescue medication containing albuterol (also known as salbutamol), a SABA, and budesonide, a corticosteroid, and has been developed in a pMDI using AstraZeneca’s Aerosphere delivery technology. The FDA approval of AIRSUPRA was based on MANDALA and DENALI Phase III trials (Approval press release). In MANDALA, AIRSUPRA significantly reduced the risk of severe exacerbations compared to albuterol in patients with moderate-to-severe asthma when used as an as-needed rescue medication in response to symptoms. For patients treated with AIRSUPRA 180 mcg/160 mcg the annualized total systemic corticosteroids dose when compared with albuterol 180 mcg was statistically significantly different, with a reduction in mean annualized dose of 40 mg per patient. In DENALI, AIRSUPRA significantly improved lung function compared to the individual components albuterol and budesonide in patients with mild to moderate asthma. About BEVESPI AEROSPHERE® BEVESPI AEROSPHERE (glycopyrronium and formoterol fumarate) is a fixed-dose dual bronchodilator in a pMDI, combining glycopyrronium, a long-acting muscarinic antagonist (LAMA), and formoterol fumarate, a long-acting beta2-agonist (LABA). PMDIs are an important choice for COPD patients where limited lung function, advanced age and reduced dexterity or cognition are significant considerations for patients to achieve therapeutic benefits from their medicines. BEVESPI AEROSPHERE is the only LABA/LAMA with Aerosphere delivery technology. Results from an imaging trial have shown that BEVESPI AEROSPHERE effectively delivers medicine to both the large and small airways. About BREZTRI AEROSPHERE® BREZTRI AEROSPHERE (budesonide, glycopyrrolate, and formoterol fumarate) is a single-inhaler, fixed-dose triple-combination of formoterol fumarate, a LABA, glycopyrronium bromide, a LAMA, with budesonide, an ICS, and delivered in a pressurized metered-dose inhaler. BREZTRI AEROSPHERE is approved to treat COPD in more than 50 countries worldwide including the US, EU, China and Japan, and is currently being studied in Phase III trials for asthma. About SYMBICORT® Symbicort (budesonide and formoterol fumarate dihydrate) is the number one ICS/LABA combination therapy in asthma and chronic obstructive pulmonary disease (COPD) in China. It is a combination formulation containing budesonide, an ICS that treats underlying inflammation, and formoterol, a LABA with a fast onset of action, in a single inhaler. Symbicort was launched in 2000 and is approved in approximately 120 countries to treat asthma and/or COPD either as Symbicort Turbuhaler or Symbicort pMDI (pressurised metered-dose inhaler).

THARROS is the first-ever prospective trial to investigate the potential of an inhaled triple therapy to reduce cardiopulmonary events, a key driver of mortality, in COPD First patients dosed in ATHLOS Phase III trial assessing impact of BREZTRI on integrated cardiopulmonary parameters associated with health status and survival in patients with COPD WILMINGTON, Del.--(BUSINESS WIRE)--AstraZeneca today announced the initiation of a Phase III trial to investigate the potential effect of triple-combination inhaled therapy BREZTRI AEROSPHERE® (budesonide/glycopyrronium/formoterol fumarate, or BGF) on severe cardiopulmonary outcomes, including death*, in people with chronic obstructive pulmonary disease (COPD) who also have elevated cardiopulmonary risk, irrespective of their exacerbation history.1 Also, the first participants have been dosed in ATHLOS, a Phase III trial investigating AstraZeneca’s triple therapy BGF vs. ICS/LABA budesonide/formoterol fumarate (BFF) or placebo on cardiopulmonary parameters including hyperinflation and exercise endurance time, which are associated with health status and survival.2 COPD impacts 391 million people globally.3 The disease’s mechanisms elevate the risk of both pulmonary and cardiac events, including severe or fatal COPD exacerbations and cardiac events, which is termed cardiopulmonary risk.4-8 This underlying risk is further increased after a COPD exacerbation and may remain elevated for up to a year following an exacerbation.9-11 Just one COPD exacerbation doubles the risk of a heart attack and increases risk of hospitalization and cardiopulmonary-related death.5,12-14 Cardiopulmonary causes are the most common reasons for death in patients with COPD.15,16 Fernando Martinez, MD, MS, Chief of the Division of Pulmonary and Critical Care Medicine at Weill Cornell Medicine and New York-Presbyterian Hospital, and International Co-ordinating Investigator in the THARROS trial said, “The 2024 GOLD Report highlights the treatment effect of non-pharmacologic interventions and inhaled triple combination therapies on mortality. The Report calls for a more proactive therapeutic approach to improve outcomes in COPD. If positive, the THARROS trial will provide critical evidence about the potential of single inhaler, triple combination therapy to reduce severe cardiopulmonary events and further advance treatment goals in COPD, including for patients with no history of exacerbations, for whom no evidence currently exists.” David Berg MD, MPH, Associate Physician in Cardiovascular and Critical Care Medicine, Brigham and Women’s Hospital, Harvard Medical School, US added: “Large outcomes trials have transformed the management of cardiovascular diseases by enhancing our understanding of the potentially broad impact of therapies targeting those diseases. Current evidence already supports a proactive treatment approach in COPD. Now THARROS is seeking to provide first-of-its-kind evidence to support a strategy of comprehensive cardiopulmonary risk reduction with a triple therapy.” Sharon Barr, Executive Vice President, BioPharmaceuticals R&D, AstraZeneca, said: “We have an important and urgent mission to eliminate COPD as a leading cause of death. Even moderate COPD exacerbations are associated with increased risks of further lung events, severe cardiovascular complications and have been shown to contribute to patients dying. With the first-of-its-kind THARROS study, we aim to demonstrate the potential of triple therapy to address cardiopulmonary risk.” BGF is approved to treat COPD in 75 countries worldwide including the US, EU, China and Japan. * The severe cardiopulmonary outcome measures investigated in THARROS include death from respiratory and cardiac causes. BREZTRI AEROSPHERE® (budesonide/glycopyrronium/formoterol fumarate) Important Safety Information BREZTRI is contraindicated in patients who have a hypersensitivity to budesonide, glycopyrrolate, formoterol fumarate, or product excipients BREZTRI is not indicated for treatment of asthma. Long-acting beta2-adrenergic agonist (LABA) monotherapy for asthma is associated with an increased risk of asthma-related death. These findings are considered a class effect of LABA monotherapy. When a LABA is used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone. Available data do not suggest an increased risk of death with use of LABA in patients with COPD BREZTRI should not be initiated in patients with acutely deteriorating COPD, which may be a life-threatening condition BREZTRI is NOT a rescue inhaler. Do NOT use to relieve acute symptoms; treat with an inhaled short-acting beta2-agonist BREZTRI should not be used more often than recommended; at higher doses than recommended; or in combination with LABA-containing medicines, due to risk of overdose. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs Oropharyngeal candidiasis has occurred in patients treated with orally inhaled drug products containing budesonide. Advise patients to rinse their mouths with water without swallowing after inhalation Lower respiratory tract infections, including pneumonia, have been reported following ICS. Physicians should remain vigilant for the possible development of pneumonia in patients with COPD as the clinical features of pneumonia and exacerbations frequently overlap Due to possible immunosuppression, potential worsening of infections could occur. Use with caution. A more serious or fatal course of chickenpox or measles can occur in susceptible patients Particular care is needed for patients transferred from systemic corticosteroids to ICS because deaths due to adrenal insufficiency have occurred in patients during and after transfer. Taper patients slowly from systemic corticosteroids if transferring to BREZTRI Hypercorticism and adrenal suppression may occur with regular or very high dosage in susceptible individuals. If such changes occur, consider appropriate therapy Caution should be exercised when considering the coadministration of BREZTRI with long-term ketoconazole and other known strong CYP3A4 Inhibitors. Adverse effects related to increased systemic exposure to budesonide may occur If paradoxical bronchospasm occurs, discontinue BREZTRI immediately and institute alternative therapy Anaphylaxis and other hypersensitivity reactions (eg, angioedema, urticaria or rash) have been reported. Discontinue and consider alternative therapy Use caution in patients with cardiovascular disorders, especially coronary insufficiency, as formoterol fumarate can produce a clinically significant cardiovascular effect in some patients as measured by increases in pulse rate, systolic or diastolic blood pressure, and also cardiac arrhythmias, such as supraventricular tachycardia and extrasystoles Decreases in bone mineral density have been observed with long-term administration of ICS. Assess initially and periodically thereafter in patients at high risk for decreased bone mineral content Glaucoma and cataracts may occur with long-term use of ICS. Worsening of narrow-angle glaucoma may occur, so use with caution. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use BREZTRI long term. Instruct patients to contact a healthcare provider immediately if symptoms occur Worsening of urinary retention may occur. Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction. Instruct patients to contact a healthcare provider immediately if symptoms occur Use caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, and ketoacidosis or unusually responsive to sympathomimetic amines Be alert to hypokalemia or hyperglycemia Most common adverse reactions in a 52-week trial (incidence ≥ 2%) were upper respiratory tract infection (5.7%), pneumonia (4.6%), back pain (3.1%), oral candidiasis (3.0%), influenza (2.9%), muscle spasms (2.8%), urinary tract infection (2.7%), cough (2.7%), sinusitis (2.6%), and diarrhea (2.1%). In a 24-week trial, adverse reactions (incidence ≥ 2%) were dysphonia (3.3%) and muscle spasms (3.3%) BREZTRI should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors and tricyclic antidepressants, as these may potentiate the effect of formoterol fumarate on the cardiovascular system BREZTRI should be administered with caution to patients being treated with: Strong cytochrome P450 3A4 inhibitors (may cause systemic corticosteroid effects) Adrenergic drugs (may potentiate effects of formoterol fumarate) Xanthine derivatives, steroids, or non-potassium sparing diuretics (may potentiate hypokalemia and/or ECG changes) Beta-blockers (may block bronchodilatory effects of beta-agonists and produce severe bronchospasm) Anticholinergic-containing drugs (may interact additively). Avoid use with BREZTRI Use BREZTRI with caution in patients with hepatic impairment, as budesonide and formoterol fumarate systemic exposure may increase. Patients with severe hepatic disease should be closely monitored INDICATION BREZTRI AEROSPHERE is indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). LIMITATIONS OF USE Not indicated for the relief of acute bronchospasm or for the treatment of asthma. Please see full BREZTRI Prescribing Information, including Patient Information.

PKP2 Mutations Are the Leading Cause of ARVC, a Dangerous Condition Linked to Sudden Cardiac Arrest in Young People Estimated to Affect 70,000 People in the US TN-401 Preclinical Studies Demonstrated Robust Reduction of Ventricular Arrhythmias and Extended Survival in Knockout Models of Disease After a Single Dose SOUTH SAN FRANCISCO, Calif., Oct. 26, 2023 (GLOBE NEWSWIRE) -- Tenaya Therapeutics, Inc. (NASDAQ: TNYA), a clinical-stage biotechnology company with a mission to discover, develop and deliver potentially curative therapies that address the underlying causes of heart disease, announced today that the U.S. Food and Drug Administration (FDA) has provided clearance of the company’s Investigational New Drug (IND) application to initiate clinical testing of TN-401. TN-401 is Tenaya’s adeno-associated virus serotype 9 (AAV9)-based investigational gene therapy product candidate for the treatment of arrhythmogenic right ventricular cardiomyopathy (ARVC) caused by mutations in the plakophilin-2 (PKP2) gene. Based on this IND clearance, the company plans to initiate the RIDGE-1™ Phase 1b clinical trial of TN-401, a multi-center, open-label study to assess the safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-401. Tenaya is currently conducting the RIDGE™ global non-interventional natural history and serotype study of PKP2-associated ARVC. ARVC, also known as arrhythmogenic cardiomyopathy (ACM), is a chronic, progressive, familial disease that typically presents before age 40. People with ARVC experience symptoms related to ventricular arrhythmias, including palpitations, lightheadedness and fainting, and are at increased risk of sudden cardiac death. PKP2 mutations are the most common genetic cause of ARVC and result in a loss of key proteins needed to maintain the structural integrity and cell-to-cell signaling of heart muscle cells. TN-401 is designed to address the underlying cause of disease by delivering a fully functional PKP2 gene to restore normal PKP2 protein levels and thereby slow disease progression and reverse the course of disease after a single dose. “People with arrhythmogenic cardiomyopathy report high levels of fear and stress and must withstand burdensome physical and lifestyle restrictions in an effort to manage the frequent abnormal heart rhythms and constant risk of sudden cardiac arrest associated with their disease,” said Whit Tingley, M.D., Ph.D., Tenaya’s Chief Medical Officer. “TN-401 is intended to address the genetic mutation most frequently underlying ARVC. The initial dose for TN-401 in the RIDGE-1 study was associated with near maximal efficacy in our preclinical studies. With clinical site and patient community engagement well underway, we look forward to rapidly advancing TN-401 into the clinic.” In preclinical studies in a knock-out mouse model of disease, Tenaya’s PKP2 gene therapy administered at a dose of 3E13 vg/kg restored normal levels of PKP2 protein expression and demonstrated durable efficacy in preventing disease development and slowing or reversing disease progression after onset leading to long-term survival. AAV9 was selected as the vector for delivery of Tenaya’s PKP2 gene therapy based on its extensive clinical and commercial safety record in thousands of patients globally and its demonstrated ability in clinical studies to broadly distribute around the human heart and robustly express in heart muscle cells. Tenaya has completed cGMP drug product manufacturing at the 1000-liter scale for TN-401 at the company’s Genetic Medicines Manufacturing Center, with sufficient drug product produced to support the entire Phase 1b study. TN-401 RIDGE-1 Phase 1b Protocol Tenaya’s RIDGE-1 Phase 1b clinical trial of TN-401 is a multi-center, open-label study to assess the safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-401. The RIDGE-1 clinical trial will seek to enroll up to fifteen adults who have been diagnosed with PKP2-associated ARVC. Trial participants must have an implantable cardioverter defibrillator (ICD) and be at increased risk for arrhythmias as determined during screening by premature ventricular contraction (PVC) count. The trial will be conducted in two stages, with dose administration and outpatient assessments through 52-weeks and a long-term follow-up segment for four-years thereafter. Enrollment will be divided into two dose cohorts, starting at a dose of 3E13 vg/kg, a dose associated with near-maximal efficacy in preclinical studies. Following dosing of the first three patients, a panel of independent safety reviewers will advise on plans to dose escalate and expand enrollment of the initial cohort. The trial protocol includes assessments of safety, markers of cardiac transduction and transgene expression in right ventricular biopsy samples, changes in PVC, sustained or non-sustained ventricular tachycardia (VT or NSVT) occurrences, circulating plasma biomarkers, imaging biomarkers of disease as measured by echocardiogram and patient-reported outcomes. About PKP2-Associated ARVC Plakophilin-2 (PKP2) mutations are the most common genetic cause of arrhythmogenic right ventricular cardiomyopathy (ARVC), estimated to represent approximately 40 percent of the overall ARVC population. The prevalence of PKP2-associated ARVC is estimated at more than 70,000 people in the U.S. alone, though it frequently goes undiagnosed as sudden cardiac death is the first sign of disease in nearly one quarter of known cases. In PKP2-associated ARVC, mutations of the PKP2 gene results in insufficient expression of a protein needed for the proper functioning of the desmosomal complex that maintains physical connections and electrical signaling between heart muscle cells. As the desmosome structure degrades, cardiac muscle cells are replaced by fibrofatty tissue and electrical pulses in the heart become unstable, resulting in adverse remodeling and irregular heart rhythms. ARVC symptoms include arrhythmias, palpitations, lightheadedness, dizziness and fainting. It is typically diagnosed before age 40, and sudden cardiac arrest due to life-threatening ventricular arrhythmias is frequently the first manifestation of disease. Current treatments include anti-arrhythmic medications, implantable cardioverter-defibrillators (ICDs) and ablation procedures, which do not address the underlying genetic cause of disease. About TN-401 Gene Therapy and the RIDGE Clinical Program TN-401 is an investigational adeno-associated virus serotype 9 (AAV9)-based gene therapy being developed for the treatment of ARVC due to disease causing variants in the PKP2 gene. AAV9 was selected as the vector for delivery of Tenaya’s PKP2 gene therapy based on its extensive clinical and commercial safety record and demonstrated ability to target heart muscle cells. In preclinical studies, Tenaya has shown that a single dose of TN-401 restored normal levels of PKP2, normalized heart rhythms, improved right and left ventricular size and function and extended survival. Tenaya has received clearance from the FDA to initiate its first-in-human RIDGE-1TM Phase 1b clinical trial of TN-401 in patients with PKP2-associated ARVC. To support TN-401’s clinical development, the company is currently enrolling the RIDGETM global non-interventional study to collect natural history and AAV9 antibody (seroprevalence) data among PKP2 gene mutation carriers with ARVC. TN-401 has received Orphan Drug Designation from the FDA.
