FDA Approves Trelegy Ellipta (fluticasone furoate/umeclidinium/vilanterol) for the Treatment of Asthma

London UK 9 September 2020 — GlaxoSmithKline plc (LSE/NYSE: GSK) and Innoviva, Inc. (NASDAQ: INVA) announced the US Food and Drug Administration (FDA) has approved a new indication for Trelegy Ellipta (fluticasone furoate / umeclidinium / vilanterol ‘FF/UMEC/VI’) for the treatment of asthma in patients aged 18 years and older adding to its current license for use in patients with chronic obstructive pulmonary disease (COPD). Trelegy Ellipta is not indicated for relief of acute bronchospasm.

The FDA-approved strength for both COPD and asthma is fluticasone furoate / umeclidinium / vilanterol 100/62.5/25mcg. There is an additional strength for asthma alone which is fluticasone furoate / umeclidinium / vilanterol 200/62.5/25mcg.

The approval means Trelegy is the first single inhaler triple therapy approved for the maintenance treatment of both asthma and COPD and is the only single inhaler triple therapy available for patients in a convenient once-daily inhalation in the US. Today’s announcement marks GSK’s sixth major medicine approval in 2020 across areas of significant unmet medical need including cancer, HIV, respiratory and chronic kidney disease.

Dr Hal Barron, Chief Scientific Officer and President R&D, GSK, said: “Millions of asthma patients in the US rely on multiple inhalers to help control their condition and manage their symptoms. Today’s approval is an important advance for these patients as it allows them to benefit from triple therapy by using one inhaler, once-a-day.”

Trelegy’s approval for the maintenance treatment of asthma in patients aged 18 years and older introduces a new paradigm for managing the approximately 30% of adult asthma patients who still experience symptoms despite being adherent to inhaled corticosteroids/ long-acting beta agonist (ICS/LABA) combination therapy.

Tonya Winders, President, Global Allergy and Airways Patient Platform (GAAPP) commented: “In the US there are almost 20 million adults[i] living with asthma and we know that many of those continue to live with and adapt their lives around ongoing symptoms, despite taking medication as prescribed by their physician. We welcome the news that for appropriate patients, Trelegy Ellipta will now be available as a new treatment option.”

Today’s approval was based on a supplemental New Drug Application which included data from the CAPTAIN study showing that in patients uncontrolled on ICS/LABA, the additional bronchodilation provided by Trelegy demonstrated significant improvements in lung function compared with FF/VI, in a single daily dose in an easy-to-use inhaler. The results from CAPTAIN were presented at the European Respiratory Society (ERS) Congress this week, reinforcing the potential of once-daily single inhaler triple therapy in asthma management.

Pavel Raifeld, Chief Executive Officer of Innoviva, said: “In 2017, Trelegy Ellipta was approved in the US as the first once-daily single inhaler triple therapy for the treatment of COPD, and it remains the market leader with strong continued growth. Today’s approval in asthma is another successful outcome for our long-standing partnership with GSK and a testament to our commitment to make innovative medicines accessible to patients with respiratory diseases.”

About Asthma

Asthma is a chronic lung disease that inflames and narrows the airways. Asthma affects 358 million people worldwide. Despite medical advances, more than half of patients continue to experience poor control and significant symptoms impacting their daily lives.

The causes of asthma are not completely understood but likely involve an interaction between a person’s genetic make-up and the environment. Key risk factors are inhaled substances that provoke allergic reactions or irritate the airways.

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) in the US

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 US under the brand name Trelegy Ellipta in September 2017 for the long-term, once-daily maintenance treatment of patients with COPD. Trelegy Ellipta was approved in the US on 9 September 2020 for the maintenance treatment of asthma in patients aged 18 years and older. Trelegy Ellipta is not indicated for relief of acute bronchospasm.
