LONDON, UNITED KINGDOM and SOUTH SAN FRANCISCO, CA--(Marketwired - April 22, 2014) - GlaxoSmithKline (LSE: GSK) (NYSE: GSK) and Theravance, Inc. (NASDAQ: THRX) today announced the start of a Phase III efficacy and safety study of a combination treatment of the inhaled corticosteroid (ICS), fluticasone furoate and long-acting beta2 agonist (LABA), vilanterol (FF/VI). The study will evaluate the contribution of the ICS component on lung function, in patients with Chronic Obstructive Pulmonary Disease (COPD). Positive results from this study will help support a potential filing of FF/VI for the treatment of patients with COPD in Japan.

The study is a 12 week, multicentre, randomised, double-blind, parallel-group study to evaluate the efficacy and safety of FF/VI 100/25mcg once daily compared with VI 25mcg once daily, administered via the Ellipta inhaler. Patients included in the study will have a history of COPD with at least one exacerbation in the year prior to screening and will demonstrate current symptoms of COPD. The study seeks to enrol approximately 1580 patients from across 250 study centres worldwide, including approximately 350 patients from centres in Japan.

About the FF/VI clinical development programme in Japanese patients
The FF/VI phase III clinical development programme in patients with COPD contained data from six studies in over 6,000 COPD patients. Specific Japanese patient efficacy data were only available from two 6-month efficacy studies. In these studies the contribution of FF 100mcg to the combination, on lung function, did not achieve statistical significance.

GSK chose to withdraw the COPD file in Japan while designing an additional study, as there were insufficient data to support the efficacy of the combination and its components in this specific patient group. Demonstration of a statistically significant contribution of FF 100mcg to the combination on lung function needs to be shown in this study, with a trend demonstrating a positive benefit in the Japanese patients sub-group, being pivotal for the approval of FF/VI 100/25mcg for treatment of COPD in Japan

FF/VI Regulatory Activity in Japan
FF/VI strengths of 100/25 mcg and 200/25 mcg were licensed by the Japanese Ministry of Health Labour and Welfare for the treatment of asthma under the trade name Relvar® Ellipta® in September 2013. Japanese Drug Information is available at http://glaxosmithkline.co.jp/healthcare/.

FF/VI is not licensed in Japan for the treatment of patients with COPD.

Important Safety Information for asthma patients in Japan receiving Relvar Ellipta
FF/VI is contraindicated in patients with hypersensitivity to fluticasone furoate, vilanterol, or any of the excipients and in patients with infections or deep mycosis against which there is no effective anti-bacterial agent (symptoms may be exacerbated due to steroid effects).

Because FF/VI is not intended for immediate relief of symptoms that have occurred, the product should not be used to relieve acute symptoms. Any other appropriate drug such as short-acting inhaled beta2 agonist (e.g. inhaled salbutamol sulphate) should be used for relief of acute symptoms.

FF/VI should be administered with caution in patients with tuberculosis or infections, patients with severe cardiac disease, and patients with hepatic impairment.

Patients should be cautioned to visit a medical institution as soon as possible to seek medical treatment if they notice increasing use or insufficient effect of the short-acting inhaled beta2 agonist because asthma management may be inadequate.

Patients should be instructed not to stop inhaling FF/VI on their own since symptoms may be exacerbated after discontinuation of the product.

As with other inhaled drugs, paradoxical bronchospasm may occur with an increase in wheezing after inhalation of FF/VI. In such a case, FF/VI should be discontinued immediately, and treatment with a short-acting inhaled bronchodilator should be given. The patient should be assessed and alternative therapy should be considered if necessary.

Asthma-related events and asthma exacerbations may occur during treatment with FF/VI. Patients should be instructed not to stop inhaling FF/VI on their own but to seek medical advice if asthma symptoms remain uncontrolled or are exacerbated after initiation of treatment with the product.

Systemic effects (including Cushing's syndrome, Cushingoid symptoms, adrenal suppression, growth retardation in children, decrease in bone mineral density, cataract, and glaucoma) may occur with inhaled steroids although these effects are less likely than with systemic steroids. Therefore, inhaled steroids should be used at the lowest dose to effectively control asthma for each patient. Particularly, patients who are treated at high doses for long periods should be monitored with regular examinations; in case systemic effects occur, appropriate measures should be taken while monitoring the patient's asthmatic symptoms.

It has been reported in a global clinical study and overseas clinical studies in patients with chronic obstructive pulmonary disease that the incidence of pneumonia showed a fluticasone furoate/vilanterol dose-dependent increase. Caution should be exercised when FF/VI is administered to patients who are generally at potentially high risk for developing pneumonia.

Caution should be exercised when considering the coadministration of FF/VI with long-term ketoconazole and other known strong CYP3A4 inhibitors because increased systemic corticosteroid and cardiovascular adverse effects may occur. Caution should also be exercised when considering the coadministration of FF/VI with beta-blockers which may weaken the effect of FF/VI.

In three global phase III clinical studies, adverse reactions including laboratory abnormalities were reported in 100 (7.1%) of a total of 1,407 patients (including 61 Japanese patients) treated with FF/VI. The common adverse reactions were dysphonia and oral candidiasis reported in 19 (1.4%) and 12 (0.9%) patients, respectively. Of 61 Japanese patients, adverse reactions including laboratory abnormalities were reported in 7 patients (11.5%). The common adverse reactions were dysphonia and oral candidiasis reported in 3 (4.9%) and 2 (3.3%) patients, respectively (at the time of approval).

In a Japanese long-term administration study, adverse reactions including laboratory abnormalities were reported in 40 (26.1%) of a total of 153 patients treated with FF/VI. The common adverse reactions were oral candidiasis and dysphonia reported in 16 (10.5%) and 10 (6.5%) patients, respectively (at the time of approval).

An anaphylactic reaction may occur (incidence unknown). Patients treated with Relvar Ellipta should be monitored closely, and if an abnormality is observed, the treatment should be discontinued and appropriate measures should be taken.
