Positive Results from the COPD Salford Lung Study
Issued: Sunday 4th September 2016
GSK announce positive results from the COPD Salford Lung Study published in the NEJM and presented at European Respiratory Congress
GlaxoSmithKline plc (LSE/NYSE: GSK) and Innoviva, Inc. (NASDAQ: INVA) today announced that the results from the pioneering Salford Lung Study (SLS) have been published in the New England Journal of Medicine (NEJM). This unique study, which reported headline results in May 2016, was designed to evaluate the effectiveness and safety of Relvar® Ellipta® in patients with chronic obstructive pulmonary disease (COPD), compared with their 'usual care' administered in an everyday clinical practice setting. Data from the study are being presented at the European Respiratory Society (ERS) International Congress on Sunday 4th September in London, (abstract number OA249).
For the primary endpoint in patients, who had exacerbated in the year before the study, treated with Relvar Ellipta 100/25mcg (fluticasone furoate 'FF'/vilanterol 'VI' or 'FF/VI') there was a statistically significant reduction of 8.4% (p=0.025; 95% CI 1.1 to 15.2) in the rate of moderate or severe exacerbations compared with patients receiving 'usual care'. The majority of these patients in the study on usual care were taking an inhaled corticosteroid (ICS) containing regimen (88%). A similar reduction in exacerbations with FF/VI was seen in those patients on an ICS/long-acting beta2-agonist (LABA) at baseline (8.0%; 95% CI 0.11 to 15.4, p=0.047).
For the intent to treat (ITT) population there were no differences observed between FF/VI and usual care on secondary outcomes measured including the time to first moderate or severe exacerbation and rate of severe exacerbations, the rate of secondary care healthcare contacts and COPD related primary care contacts. There were more primary care contacts overall on FF/VI (12.3% increase, 95% CI 5.4 to19.6). The COPD Assessment Test (CAT), which measures the impact of disease on health status, demonstrated 45% of patients receiving FF/VI improved their CAT score by 2 or more, a clinically relevant improvement, compared to 36% in the usual care group (odds ratio 1.51, 95% CI, 1.28 to 1.77).
The incidence of serious adverse events (SAE) was similar between the groups (29% FF/VI, 27% usual care). For pneumonia, an SAE of special interest, FF/VI demonstrated non-inferiority (7% FF/VI vs 6% usual care). This endpoint was a post-authorisation measure requested by the European Medicines Agency (EMA).
Neil Barnes, Global Medical Head, Respiratory Franchise at GSK said: "In the SLS study we included a broad spectrum of patients who had minimal interventions to see if this would allow us to observe a difference between treatments. The results from SLS provide robust evidence that will enable the healthcare community to begin to understand how the choice of COPD treatment can significantly influence patient outcomes. We are continuing to analyse the data from the study as we know there is so much more we will learn and we look forward to sharing our findings in future publications. I want to thank all of the patients who participated and the partners who collaborated with GSK to make this unique study possible."
Michael W. Aguiar, President and Chief Executive Officer of Innoviva said: "The data being presented at ERS and published in NEJM confirm the effectiveness of Relvar Ellipta compared with not only usual care, but also with those patients who were taking a different medicine in the same ICS/LABA class. These are important data to share with physicians, from a unique study carried out in conditions closely reflecting everyday clinical practice."
The study was made possible through collaboration between GSK, North West e-Health (NWEH), The University of Manchester, Salford Royal NHS Foundation Trust, University Hospital of South Manchester (UHSM), NHS Salford and GPs and community pharmacists in Salford, Trafford and South Manchester.
A second Salford Lung Study is currently being conducted in patients with asthma, with results expected in 2017.
Study Design
The Salford Lung Study is a Phase IIIb multi-centre, open label randomised controlled trial (RCT). The objective of the SLS COPD study was to compare the effectiveness and safety profile of FF/VI 100/25mcg with existing COPD usual care. All suitable patients with COPD at 80 primary care sites in and around Salford and South Manchester were identified from practice databases, and invited to participate in the study by their own GP.
In total, 2802 patients with COPD were randomised 1:1 to receive FF/VI 100/25mcg, with or without a long-acting muscarinic antagonists (LAMA), or to continue to receive usual care. FF/VI was administered once daily via the Ellipta inhaler. Patients who were taking a LAMA in addition to ICS/LABA therapy (triple therapy) who were randomised to the FF/VI group were able to continue to use LAMA therapy in addition to FF/VI. Usual care was taken as advised by the prescribing clinician, and could include single or dual long-acting bronchodilator therapy, inhaled corticosteroid either alone or in combination with a long acting bronchodilator or triple therapy of a LAMA, a LABA and an inhaled corticosteroid.
The Salford Lung Study had minimal exclusion criteria and involved a broad demographic of patients. Patients were followed for a period of 12 months in a normal clinical practice setting using a single electronic medical record (EMR), linking primary care (patients seen by their general practitioner), secondary care (patients seen in a hospital setting) and pharmacy data. Throughout the duration of the study physicians were allowed to modify or switch treatment at any point in the study, as would happen in normal clinical practice, the only exception being a switch from usual care to FF/VI.
The study team was able to monitor all hospital admissions, outpatient and emergency department visits, as well as data from primary care (including all healthcare contacts, out-of-hours activity and prescriptions of antibiotics or oral steroids) via the electronic health-records.
The primary effectiveness endpoint is the mean annual rate of moderate or severe exacerbations, where a moderate exacerbation is defined as the subject receiving an exacerbation-related prescription (given to treat an acute worsening of COPD symptoms) of oral corticosteroid and/or antibiotic with or without NHS contact, not requiring hospitalisation. A severe exacerbation is defined as an exacerbation-related hospitalisation - a direct result of an acute worsening of symptoms of COPD or a prolonged hospitalization as a result of a COPD exacerbation.
What is COPD?
Chronic obstructive pulmonary disease (COPD) is a disease of the lungs that includes chronic bronchitis, emphysema or both. COPD is characterised by obstruction to airflow that interferes with normal breathing. Cigarette smoke, breathing in second-hand smoke, air pollution including biomass fuels, chemical fumes and dust from the environment or workplace can all contribute to COPD.
People with COPD can experience a sudden worsening in symptoms, known as an exacerbation. Symptoms of an exacerbation can include an increase in breathlessness, coughing and mucus production, as well as fever. In these cases, the patient may need to change their medication or even, in some cases, be admitted to hospital. Exacerbations are common; one in three patients with severe COPD and almost half of patients with very severe COPD had frequent exacerbations (two or more in the first year following diagnosis). Every exacerbation can cause permanent lung damage and repeated exacerbations can accelerate the progression of the disease. People with frequent exacerbations have a poorer quality of life and may have an increased risk of death.

Important Safety Information (ISI) for FF/VI (Breo Ellipta) in the US
The following ISI is based on the Highlights section of the US Prescribing Information for Breo Ellipta. Please consult the full Prescribing Information for all the labelled safety information for Breo Ellipta.
Long-acting beta2-adrenergic agonists (LABA), such as vilanterol, one of the active ingredients in BREO ELLIPTA, increase the risk of asthma-related death. A placebo-controlled trial with another LABA (salmeterol) showed an increase in asthma-related deaths. This finding with salmeterol is considered a class effect of all LABA. Currently available data are inadequate to determine whether concurrent use of inhaled corticosteroids (ICS) or other long-term asthma control drugs mitigates the increased risk of asthma-related death from LABA.
Breo Ellipta is contraindicated for primary treatment of status asthmaticus or other acute episodes of COPD or asthma where intensive measures are required and in patients with severe hypersensitivity to milk proteins or who have demonstrated hypersensitivity to either fluticasone furoate, vilanterol, or any of the excipients.
Breo Ellipta should not be initiated in patients during rapidly deteriorating or potentially life-threatening episodes of COPD or asthma, or used for the relief of acute symptoms, i.e., as rescue therapy for the treatment of acute episodes of bronchospasm. Acute symptoms should be treated with an inhaled, short-acting beta2-agonist.
Breo Ellipta should not be used more often than recommended, at higher doses than recommended, or in conjunction with other medications containing LABAs, as an overdose may result.
Oropharyngeal candidiasis has occurred in patients treated with Breo Ellipta. Patients should be advised to rinse their mouth with water without swallowing after inhalation to help reduce this risk.
An increase in the incidence of pneumonia has been observed in subjects with COPD receiving the fluticasone furoate/vilanterol combination, including Breo Ellipta 100 mcg/25 mcg, in clinical trials. There was also an increased incidence of pneumonias resulting in hospitalisation. In some incidences these pneumonia events were fatal.
Patients who use corticosteroids are at risk for potential worsening of existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex. A more serious or even fatal course of chickenpox or measles may occur in susceptible patients.
Particular care is needed for patients who have been transferred from systemically active corticosteroids to inhaled corticosteroids because deaths due to adrenal insufficiency have occurred in patients with asthma during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids.
Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage of inhaled corticosteroids in susceptible individuals.
Caution should be exercised when considering the coadministration of Breo Ellipta with long‐term ketoconazole and other known strong CYP3A4 inhibitors because increased systemic corticosteroid and cardiovascular adverse effects may occur.
Breo Ellipta can produce paradoxical bronchospasm which may be life-threatening.
Hypersensitivity reactions such as anaphylaxis, angioedema, rash, and urticaria may occur after administration of Breo Ellipta.
Vilanterol, the LABA in Breo Ellipta, can produce clinically significant cardiovascular effects in some patients as measured by increases in pulse rate, systolic or diastolic blood pressure, and also cardiac arrhythmias. Breo Ellipta should be used with caution in patients with cardiovascular disorders.
Decreases in bone mineral density have been observed with long-term administration of products containing inhaled corticosteroids, as have glaucoma, increased intraocular pressure, and cataracts.
Breo Ellipta 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 medicines may produce significant hypokalemia in some patients. Beta-adrenergic agonist medicines may produce transient hyperglycemia in some patients.
For COPD, the most common adverse reactions (≥3% and more common than in placebo) reported in two 6-month clinical trials with Breo Ellipta 100/25 (and placebo) were nasopharyngitis, 9% (8%); upper respiratory tract infection, 7% (3%); headache, 7% (5%); and oral candidiasis, 5% (2%). In addition to the reactions reported in the 6-month studies, adverse reactions occurring in ≥3% of the subjects treated with Breo Ellipta 100/25 in two 1-year studies included back pain, pneumonia, bronchitis, sinusitis, cough, oropharyngeal pain, arthralgia, influenza, pharyngitis, and pyrexia.
