GSK filing accepted by European Medicines Agency for Trelegy Ellipta use in adult patients with asthma

Issued: London, UK

GlaxoSmithKline plc (GSK) and Innoviva, Inc. (INVA) today announced the acceptance of a regulatory submission seeking an additional indication for the use of once-daily, single-inhaler triple therapy, Trelegy Ellipta (fluticasone furoate/umeclidinium/vilanterol or FF/UMEC/VI) for the treatment of asthma in adults by the European Medicines Agency (EMA).

The submission is supported by the pivotal Phase III clinical study (CAPTAIN), conducted in 2,436 adult asthma patients across 15 countries whose disease remained inadequately controlled despite treatment with a combination of an inhaled corticosteroid and a long-acting β2-agonist (ICS/LABA). The study met its primary endpoint, demonstrating a statistically significant improvement in lung function compared with the ICS/LABA, Relvar/Breo Ellipta.

There is currently no single inhaled triple therapy available for the treatment of asthma in Europe. Asthma, a chronic lung disease that inflames and narrows the airways, affects 358 million people worldwide^[1]. Even when adherent to ICS/LABA treatment, at least 30% of asthma patients continue to experience symptoms^[2], indicating that they require further treatment.

Trelegy Ellipta was approved in the European Union in November 2017 for the treatment of patients with Chronic Obstructive Pulmonary Disease (COPD) who are not adequately treated by an ICS/LABA combination, or a combination of LABA and long-acting muscarinic antagonist (LAMA). If approved this would be the first once-daily single inhaler triple therapy available for asthma and COPD.

Regulatory applications have also been submitted for the Trelegy duplicate licences, Elebrato Ellipta and Temybric Ellipta. Submissions for the use of Trelegy Ellipta for the treatment of adult asthma patients were accepted for filing in the US by the FDA in December 2019 and in Japan by the Ministry of Health, Labour and Welfare in November 2019, and these regulatory review processes are ongoing.

About the CAPTAIN Study

CAPTAIN (Clinical study of Asthma Patients receiving Triple therapy through A single INhaler) was a randomised, double-blind, active controlled, six-arm parallel group, global multicentre study evaluating FF/UMEC/VI (100/62.5/25 mcg, 200/62.5/25 mcg, 100/31.25/25 mcg, and 200/31.25/25 mcg) versus FF/VI (100/25 mcg and 200/25 mcg) given once-daily to patients whose asthma was inadequately controlled despite treatment with ICS/LABA (>250 mcg/day fluticasone propionate, or equivalent) maintenance asthma medication.

About Trelegy Ellipta (FF/UMEC/VI)

FF/UMEC/VI is a combination of three molecules in a single inhaler that only needs to be 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.

FF/UMEC/VI was approved in the EU under the brand name Trelegy Ellipta in November 2017 for the long-term, once-daily maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). Trelegy Ellipta is not indicated for relief of acute bronchospasm or for the treatment of asthma.

Important Safety Information (ISI) for Trelegy Ellipta

The following ISI is based on the Highlights section of the US Prescribing Information for Trelegy Ellipta. Please consult the full Prescribing Information for all the labelled safety information.

Trelegy Ellipta is NOT indicated for the relief of acute bronchospasm or for the treatment of asthma

Trelegy Ellipta is contraindicated in patients with severe hypersensitivity to milk proteins or any of the ingredients.

LABA monotherapy increases the risk of serious asthma-related events.

Trelegy Ellipta should not be initiated in patients experiencing episodes of acutely deteriorating COPD. Do not use Trelegy Ellipta to treat acute symptoms.

Trelegy Ellipta should not be used in combination with other medicines containing LABA because of risk of overdose.

Candida albicans infection of the mouth and pharynx has occurred in patients treated with fluticasone furoate, a component of Trelegy Ellipta. Monitor patients periodically. Advise the patient to rinse his/her mouth with water without swallowing after inhalation to help reduce the risk.

There is an increased risk of pneumonia in patients with COPD taking Trelegy Ellipta. Monitor patients for signs and symptoms of pneumonia.

Patients who use corticosteroids are at risk for potential worsening of infections (e.g. existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex). Use Trelegy Ellipta with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients.

There is a risk of impaired adrenal function when transferring from systemic corticosteroids. Taper patients slowly from systemic corticosteroids if transferring to Trelegy Ellipta.

Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage of Trelegy Ellipta in susceptible individuals. If such changes occur, consider appropriate therapy.

If paradoxical bronchospasm occurs, discontinue Trelegy Ellipta and institute alternative therapy.

Use Trelegy Ellipta with caution in patients with cardiovascular disorders because of beta-adrenergic stimulation.

Assess patients for decrease in bone mineral density initially and periodically thereafter after prescribing Trelegy Ellipta.

Consider referral to an ophthalmologist in patients who develop ocular symptoms or use TRELEGY ELLIPTA long term. Worsening of narrow-angle glaucoma may occur. Use with caution in patients with narrow-angle glaucoma and instruct patients to contact a healthcare provider immediately if symptoms occur.

Worsening of urinary retention may occur in patients taking Trelegy Ellipta. Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction and instruct patients to contact a healthcare provider immediately if symptoms occur.

Use Trelegy Ellipta with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, and ketoacidosis.

Be alert to hypokalemia and hyperglycemia in patients taking Trelegy Ellipta.

The most common adverse reactions reported for Trelegy Ellipta (incidence ≥1%) are upper respiratory tract infection, pneumonia, bronchitis, oral candidiasis, headache, back pain, arthralgia, influenza, sinusitis, pharyngitis, rhinitis, dysgeusia, constipation, urinary tract infection, diarrhea, gastroenteritis, oropharyngeal pain, cough, and dysphonia.
