Regulatory update: GSK and Theravance announce intention to file Relvar® Ellipta® for COPD in Japan
Issued: London UK and South San Francisco, CA, USA – LSE Announcement
GlaxoSmithKline (LSE/NYSE: GSK) and Theravance, Inc. (NASDAQ: THRX) today announced the intention to file a supplemental Japanese New Drug Application (sJNDA) for Relvar® Ellipta® (fluticasone furoate “FF”/vilanterol “VI” or “FF/VI”) for the treatment of chronic obstructive pulmonary disease (COPD) with the Japanese regulatory authority during the first quarter of 2016. This decision follows results from an additional global phase III efficacy and safety study.
As previously announced, Study 200820 was designed to provide additional data for the combination, FF/VI, compared with its component, VI, in Japanese patients with COPD, as there were insufficient efficacy data in this specific COPD patient group within the FF/VI phase III clinical development programme.
The study which included 1620 patients with COPD, of whom 370 were from Japan, showed that patients who received FF/VI 100/25mcg achieved a statistically significant improvement in lung function (as measured by change from baseline in trough FEV1) compared with VI 25mcg at 12 weeks (p=0.001).
The most frequently reported adverse events in the study (greater than or equal to 3% in any group) were nasopharyngitis (6% VI, 6% FF/VI), COPD exacerbation (4% VI, 2% FF/VI) and headache (2% VI, 4% FF/VI).
Pneumonia as an adverse event of special interest was reported in 7 subjects in each treatment group (<1% VI, <1% FF/VI).
The full results from the study will be the subject of a future publication / presentation.
The 12-week, phase IIIa, multi-centre, randomised, stratified (reversibility status), double-blind, parallel-group study evaluated the contribution of FF 100mcg to FF/VI 100/25mcg once daily to lung function (as measured by trough FEV1) by comparison with VI 25mcg, in patients with moderate to severe COPD. Patients enrolled in the study were required to have had at least one COPD exacerbation that required systemic/oral corticosteroids and/or antibiotics and/or hospitalisation in the 12 months prior to screening and current symptoms of COPD, defined as a combined symptom score (combination of breathlessness, cough, sputum, and night-time awakenings requiring treatment with albuterol [salbutamol]) of ≥4 on at least 5 of the 7 days immediately preceding the Randomisation Visit.
Patients in the study were randomised 1:1 to receive FF/VI 100/25 mcg or VI 25 mcg. All treatments were administered once daily in the dry powder inhaler (DPI) Ellipta®. The study was conducted in 11 countries, with 23% of patients from Japan. The study is listed on www.clinicaltrials.gov (NCT02105974).
FF/VI is not currently indicated for the treatment of COPD in Japan. FF/VI was approved by the Japanese Ministry of Health, Labour and Welfare (MHLW) for the regular treatment of asthma in patients aged 15 years and older in September 2013.
Relvar Ellipta, or FF/VI, is also known as Breo Ellipta in some other markets, including the US.
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.
Orally inhaled corticosteroids may cause a reduction in growth velocity when administered in children and adolescents.
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.
For asthma, the most common adverse reactions in a 12-week trial (incidence ≥2% and more common than placebo) reported with Breo Ellipta 100/25 (and placebo) were nasopharyngitis 10% (7%), headache 5% (4%), oropharyngeal pain 2% (1%), oral candidiasis 2% (0%), and dysphonia 2% (0%). In a separate 12-week trial the most common adverse reactions (≥2% incidence) reported with Breo Ellipta 100/25 or 200/25 were headache, nasopharyngitis, influenza, upper respiratory tract infection, oropharyngeal pain, sinusitis, bronchitis, and cough. In addition to adverse reactions reported in the 12 week studies, adverse reactions (≥2% incidence) reported with Breo Ellipta 200/25 in a 24-week trial included viral respiratory tract infection, pharyngitis, pyrexia, and arthralgia, and with Breo Ellipta 100/25 or 200/25 in a 12-month trial included pyrexia, back pain, extrasystoles, upper abdominal pain, respiratory tract infection, allergic rhinitis, pharyngitis, rhinitis, arthralgia, supraventricular extrasystoles, ventricular extrasystoles, acute sinusitis, and pneumonia.
