GlaxoSmithKline plc (LSE/NYSE: GSK) and Innoviva, Inc. (NASDAQ: INVA) today announced that the European Commission has authorised an expanded label for once-daily Trelegy Ellipta (fluticasone furoate/umeclidinium/vilanterol ?FF/UMEC/VI?), recognising its effect on exacerbations and making it the first single inhaler triple therapy indicated for patients with moderate to severe chronic obstructive pulmonary disease (COPD) not adequately treated with dual bronchodilation or with an inhaled corticosteroid (ICS) and a long-acting ?2-agonist (LABA). Dr. Hal Barron, Chief Scientific Officer and President, R&D, GSK, said, ?We are pleased that the European Commission has approved the expanded use of Trelegy Ellipta as this will enable even more COPD patients to benefit from this important medicine.? While bronchodilation is recognised as the foundation of COPD therapy, many patients may continue to struggle with symptoms and exacerbations over time. The expanded indication for Trelegy Ellipta reflects the evidence supporting its potential benefits in a broader group of patients than originally indicated, giving them the option of taking a once-daily single inhaler triple therapy for the first time. Dr. Paul Meunier, VP, Respiratory Medicine at Innoviva, added, ?We are delighted that once-daily single inhaler triple therapy will now be available for COPD patients requiring a step up from dual bronchodilation, giving them a new option to help manage their disease.? The label update is based on data from the landmark InforMing the PAthway of COPD Treatment (IMPACT) study which showed Trelegy Ellipta was superior to both the ICS/LABA Relvar/Breo Ellipta (FF/VI) and long-acting muscarinic receptor antagonist (LAMA)/LABA Anoro Ellipta (UMEC/VI) in patients with moderate to severe COPD on multiple clinically important endpoints, including reducing exacerbations and improving lung function and health related quality of life. The new indication for Trelegy Ellipta is as a maintenance treatment in adult patients with moderate to severe COPD who are not adequately treated by a combination of an ICS and a LABA or a combination of a LABA and a LAMA (for effects on symptom control and prevention of exacerbations see section 5.1). It was originally approved in the European Union (EU) in November 2017 as a maintenance treatment in adult patients with moderate to severe COPD who are not adequately treated by a combination of an ICS and a LABA (for effects on symptom control see section 5.1).

About IMPACT

The landmark 10,355-patient InforMing the PAthway of COPD Treatment (IMPACT) study is the first study to directly compare three commonly-used COPD combination treatment classes delivered using the same dose and inhaler. It is the second of two Phase III studies designed to investigate the efficacy and safety of FF/UMEC/VI in a single inhaler compared to other commonly-used COPD combination treatments.[1] IMPACT evaluated as its primary endpoint the annual rate of on-treatment moderate/severe exacerbations for FF/UMEC/VI (100/62.5/25mcg) compared with its components, FF/VI (100/25mcg) and UMEC/VI (62.5/25mcg), two once-daily dual COPD therapies from GSK?s existing portfolio. Results from IMPACT were published in the New England Journal of Medicine.[2]

About Trelegy Ellipta (FF/UMEC/VI)

FF/UMEC/VI is the first COPD treatment to provide a combination of three molecules in a single inhaler that is taken in a single inhalation, once a day. It contains fluticasone furoate, an inhaled corticosteroid, umeclidinium, a long-acting muscarinic antagonist; and vilanterol, a long-acting beta2-adrenergic agonist, delivered in GSK?s Ellipta dry powder inhaler, which is used across the entire new portfolio of inhaled COPD medicines. Data from across multiple clinical programmes have demonstrated the benefit/risk of the molecules in FF/UMEC/VI alone and in combination for the treatment of COPD and it has been approved for use in appropriate patients with COPD in both the US and the EU. FF/UMEC/VI is approved in Europe as a maintenance treatment in adult patients with moderate to severe COPD who are not adequately treated by a combination of an ICS and a LABA or a combination of a LABA and a LAMA (for effects on symptom control and prevention of exacerbations see section 5.1). The European Summary of Product Characteristics is available at: https://www.medicines.org.uk/emc/medicine/34357 FF/UMEC/VI is approved in the US for the long-term, once-daily, maintenance treatment of airflow obstruction in patients with COPD, including chronic bronchitis and/or emphysema. It is also indicated to reduce exacerbations of COPD in patients with a history of exacerbations. It is not indicated for relief of acute bronchospasm or for the treatment of asthma. Full US Prescribing Information, including Patient Information is available here. FF/UMEC/VI has been approved in a number of other countries with further regulatory applications ongoing.

About COPD

COPD is a progressive lung disease that is thought to affect around 384 million people worldwide.[3] For people living with COPD, the inability to breathe normally can consume their daily lives and make simple activities, like walking upstairs, an everyday struggle. Patients with COPD suffer from symptoms of breathlessness and many have a significant risk of exacerbations. Managing these aspects of the disease drives physician treatment choice. Long-term exposure to inhaled irritants that damage the lungs and the airways are usually the cause of COPD. Cigarette smoke, breathing in second hand smoke, air pollution, chemical fumes or dust from the environment or workplace can all contribute to COPD. Most people who have COPD are at least 40 years old when symptoms begin.[4] Every person with COPD is different, with different needs, different challenges and different goals. Understanding this and providing support to help meet these needs is the foundation of GSK?s work.

GSK?s commitment to respiratory disease

GSK has led the way in developing innovative medicines to advance the management of asthma and COPD for nearly 50 years. Over the last five years we have launched six innovative medicines responding to continued unmet patient need, despite existing therapies. This is an industry-leading portfolio in breadth, depth and innovation, developed to reach the right patients, with the right treatment. We remain at the cutting-edge of scientific research into respiratory medicine, working in collaboration with patients and the scientific community to offer innovative medicines aimed at helping to treat patients? symptoms and reduce the risk of their disease worsening. While respiratory diseases are clinically distinct, there are important pathophysiological features that span them, and our ambition is to have the most comprehensive portfolio of medicines to address a diverse range of respiratory diseases. To achieve this, we are focusing on targeting the underlying disease-driving biological processes to develop medicines with applicability across multiple respiratory diseases. This approach requires extensive bioinformatics, data analytic capabilities, careful patient selection and stratification by phenotype in our clinical trials.

Important Safety Information for FF/UMEC/VI in the EU

The following Important Safety Information is based on a summary of the Summary of Product Characteristics for Trelegy Ellipta (FF/UMEC/VI).?Please consult the full Summary of Product Characteristics for all the safety information. FF/UMEC/VI is contraindicated in patients with hypersensitivity to either fluticasone furoate (FF), umeclidinium (UMEC), vilanterol (VI) or any of the excipients. FF/UMEC/VI should not be used in patients with asthma since it has not been studied in this patient population. FF/UMEC/VI is not indicated for the treatment of acute episodes of bronchospasm. In the event of deterioration of COPD during treatment with FF/UMEC/VI, a re-evaluation of the patient and of the COPD treatment regimen should be undertaken. Administration of FF/UMEC/VI may produce paradoxical bronchospasm that may be life-threatening. Cardiovascular effects, such as cardiac arrhythmias e.g. atrial fibrillation and tachycardia, may be seen after the administration of muscarinic receptor antagonists and sympathomimetics, including FF/UMEC/VI. Therefore, FF/UMEC/VI should be used with caution in patients with unstable or life-threatening cardiovascular disease. Systemic steroid effects may occur with any inhaled corticosteroid (ICS), particularly at high doses prescribed for long periods.? These effects are much less likely to occur than with oral corticosteroids. Patients with moderate to severe hepatic impairment receiving FF/UMEC/VI should be monitored for systemic corticosteroid-related adverse reactions. If a patient presents with symptoms such as blurred vision or other visual disturbances, the patient should be considered for referral to an ophthalmologist for evaluation of possible causes which may include cataract, glaucoma or rare diseases such as central serous chorioretinopathy (CSCR) which have been reported after use of systemic and topical corticosteroids. FF/UMEC/VI should be used with caution in patients with convulsive disorders or thyrotoxicosis, in patients who are unusually responsive to beta₂-adrenergic agonists and in patients with pulmonary tuberculosis or in patients with chronic or untreated infection. Consistent with its antimuscarinic activity, FF/UMEC/VI should be used with caution in patients with urinary retention or with narrow-angle glaucoma. An increase in the incidence of pneumonia, including pneumonia requiring hospitalisation, has been observed in patients with COPD receiving ICS. There is some evidence of an increased risk of pneumonia with increasing steroid dose but this has not been demonstrated conclusively across all studies. There is no conclusive clinical evidence for intra-class differences in the magnitude of the pneumonia risk among ICS products. Beta₂-adrenergic agonists may produce significant hypokalaemia in some patients, which has the potential to produce adverse cardiovascular effects. The decrease in serum potassium is usually transient, not requiring supplementation. No clinically relevant effects of hypokalaemia were observed in clinical studies with FF/UMEC/VI at the recommended therapeutic dose. Caution should be exercised when FF/UMEC/VI is used with other medicinal products that also have the potential to cause hypokalaemia. Beta₂-adrenergic agonists may produce transient hyperglycemia in some patients. No clinically relevant effects on plasma glucose were observed in clinical studies with FF/UMEC/VI at the recommended therapeutic dose. Upon initiation of treatment with FF/UMEC/VI, plasma glucose should be monitored more closely in diabetic patients. There have been reports of increases in blood glucose levels in diabetic patients treated with fluticasone furoate/umeclidinium/vilanterol and this should be considered when prescribing to patients with a history of diabetes mellitus. This medicinal product contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take FF/UMEC/VI. The most frequently reported adverse reactions with FF/UMEC/VI were nasopharyngitis (7%), headache (5%) and upper respiratory tract infection (2%). Other common adverse reactions (reported with a frequency of =1/100 to <1/10) include: pneumonia, pharyngitis, rhinitis, influenza, cough, arthralgia and back pain.
