GSK Study Demonstrates Superiority of Anoro Ellipta to Stiolto Respimat in Improving Lung Function in Chronic Obstructive Pulmonary Disease

LONDON--(BUSINESS WIRE)-- GlaxoSmithKline (LSE/NYSE: GSK) and Innoviva, Inc. (NASDAQ: INVA) today announced positive data from a study comparing a once-daily long-acting muscarinic antagonist (LAMA) and a long-acting beta agonist (LABA) fixed-dose combination, Anoro Ellipta (umeclidinium/vilanterol 62.5mcg/25mcg; UMEC/VI) and Stiolto Respimat (tiotropium/olodaterol 5mcg/5mcg; TIO/OLO), for symptomatic patients with chronic obstructive pulmonary disease (COPD). These data have been published today in Advances in Therapy¹ and are being presented today at the CHEST annual meeting of the American College of Chest Physicians in Toronto, Canada.

The primary endpoint for this eight-week, open-label, cross-over study of 236 patients with COPD was the demonstration of non-inferiority of UMEC/VI compared to TIO/OLO in improving lung function, as measured by trough FEV1 (Forced Expiratory Volume in 1 second) at week eight. This endpoint was met, and furthermore UMEC/VI demonstrated superiority to TIO/OLO, with a difference in treatment effect of 52mL on trough FEV1 at week eight (UMEC/VI 180mL vs. TIO/OLO 128mL; 95% CI: 28, 77; p<0.001).

Both treatments demonstrated a comparable tolerability and safety profile with an overall incidence of on-treatment adverse events of 25% in the UMEC/VI group and 31% in the TIO/OLO group. The most frequently-reported adverse events were upper respiratory tract infections (UMEC/VI 8%; TIO/OLO 9%), cough (UMEC/VI 1%; TIO/OLO 1%) and diarrhoea (UMEC/VI 1%; TIO/OLO 1%).

Eric Dube, SVP, Head Global Respiratory, GSK said, “Improving lung function is a clear goal in patients with COPD.² The challenge for healthcare professionals to date has been the lack of differentiation within the LAMA/LABA class. That is why we have conducted this study, as the first in-class head-to-head comparison of two fixed-dose once-daily LAMA/LABAs. These data demonstrate that UMEC/VI (Anoro) provides superior lung function improvements to the comparator TIO/OLO.”

Michael Aguiar, CEO of Innoviva said, “COPD is a progressive, chronic disease, affecting over 300 million people worldwide. We believe that these data clearly demonstrate the benefit of Anoro Ellipta versus Stiolto Respimat for symptomatic, moderate COPD patients whose primary therapeutic need is additional bronchodilatation and we are very pleased with these results.”

About COPD

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. 384 million people have COPD² and it is estimated to become the 3rd leading cause of death worldwide by 2030.³ Long-term exposure to lung 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.

About the Head-to-Head Study

The Anoro Ellipta (umeclidinium/vilanterol 62.5mcg/25mcg; UMEC/VI) versus Stiolto Respimat (tiotropium/olodaterol 5mcg/5mcg; TIO/OLO) head-to-head study is the first direct comparison of two fixed-dose once-daily LAMA/LABA combination therapies for COPD.

The study involved 236 adult symptomatic (MMRC >/= 2) patients with moderate COPD (post bronchodilator FEV1 ≤50 and ≥70% of predicted value), not receiving inhaled corticosteroid therapy at inclusion in the study, from 34 centres across Germany, Spain, UK and US. The primary objective of the study was to demonstrate that UMEC/VI was non-inferior to TIO/OLO in lung function at week eight, as measured by trough FEV1 (Forced Expiratory Volume in 1 second) with a non-inferiority margin of -50mL in the per protocol (PP) population. If non-inferiority was established, which was the case, superiority was then tested in the intent-to-treat (ITT) population.

The study was an 8-week, multicentre, randomised, open-label, two-period cross-over design. After an initial two week run-in period, eligible patients were randomised to receive UMEC/VI (62.5/25 mcg one inhalation once-daily) via the Ellipta inhaler followed by TIO/OLO 5/5 mcg (2 puffs of TIO/OLO 2.5/2.5 mcg once-daily) via the Respimat inhaler (each for 8 weeks with an interim 3-week washout), or vice versa. Treatments were administered open-label, since the inhalers were potentially identifiable, but spirometry was conducted in assessor-blind conditions.

About Anoro Ellipta

Anoro Ellipta (umeclidinium and vilanterol inhalation powder) is a combination of two bronchodilators in a single dry powder inhaler, the Ellipta. It contains umeclidinium (UMEC), a long-acting muscarinic antagonist (LAMA) and vilanterol (VI), a long-acting beta₂ agonist (LABA). The dose of UMEC/VI is labelled as 55/22mcg in Europe (delivered dose) and 62.5/25mcg in the US (dispensed dose) and is delivered in the Ellipta inhaler.

Important Safety Information for Anoro Ellipta in the US

The following Important Safety Information (ISI) is based on the Highlights section of the Prescribing Information for Anoro Ellipta. Please consult the full Prescribing Information for all the labeled safety information for Anoro Ellipta.

Long-acting beta₂-adrenergic agonists (LABA), such as vilanterol, 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. The safety and efficacy of Anoro in patients with asthma have not been established. Anoro is not indicated for the treatment of asthma.

Anoro is contraindicated in patients with severe hypersensitivity to milk proteins or any ingredients.

Anoro should not be initiated in patients during rapidly deteriorating or potentially life-threatening episodes of COPD, or as rescue therapy for the treatment of acute episodes of bronchospasm, which should be treated with an inhaled, short-acting beta₂-agonist.

Anoro should not be used more often than recommended, at higher doses than recommended, or in conjunction with additional medicine containing a LABA, as an overdose may result.

Anoro should be used with caution when considering coadministration with long-term ketoconazole and other known strong cytochrome P450 3A4 inhibitors because increased cardiovascular adverse effects may occur.

Anoro can produce paradoxical bronchospasm, which may be life-threatening.

Anoro should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.

Anoro should be used with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, ketoacidosis, and in patients who are unusually responsive to sympathomimetic amines.

Anoro should be used with caution in patients with narrow-angle glaucoma. Instruct patients to contact a physician immediately should any signs or symptoms of narrow-angle glaucoma occur.

Anoro should be used with caution in patients with urinary retention, especially in patients with prostatic hyperplasia or bladder neck obstruction. Instruct patients to contact a physician immediately should any signs or symptoms of urinary retention occur.

Beta-adrenergic agonist medicines may produce significant hypokalemia and transient hyperglycemia in some patients.

The most common adverse reactions (incidence ≥1% and more common than placebo) with Anoro were pharyngitis, sinusitis, lower respiratory tract infection, constipation, diarrhea, pain in extremity, muscle spasms, neck pain, and chest pain.

Beta₂-agonists, such as vilanterol should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors, tricyclic antidepressants, or drugs known to prolong the QTc interval or within 2 weeks of discontinuation of such agents, because the effect of adrenergic agonists on the cardiovascular system may be potentiated.

Use beta‐blockers with caution as they not only block the pulmonary effect of beta‐agonists, such as vilanterol, but may produce severe bronchospasm in patients with COPD.

Use with caution in patients taking non–potassium-sparing diuretics, as electrocardiographic changes and/or hypokalemia associated with non–potassium-sparing diuretics may worsen with concomitant beta-agonists.

Avoid co-administration of Anoro with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic adverse effects such as cardiovascular effects, worsening of narrow-angle glaucoma, and worsening of urinary retention.
