GSK and Theravance announce start of phase III lung function study with ‘closed’ triple combination treatment FF/UMEC/VI for COPD

GlaxoSmithKline plc (LSE/NYSE: GSK) and Theravance, Inc. (NASDAQ: THRX) today announced the start of a second global phase III study

Issued: London UK and South San Francisco, CA

GlaxoSmithKline plc (LSE/NYSE: GSK) and Theravance, Inc. (NASDAQ: THRX) today announced the start of a second global phase III study to evaluate the effects of the investigational once-daily closed triple combination of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) in patients with chronic obstructive pulmonary disease (COPD).

Enrolling approximately 1,800 patients, the FULFIL study will assess whether the inhaled corticosteroid, long-acting muscarinic antagonist and long-acting beta2-adrenergic agonist (ICS/LAMA/LABA) combination, all delivered in GSK’s Ellipta® inhaler, can improve lung function and health-related quality of life compared with budesonide/formoterol, a twice-daily ICS/LABA combination delivered via the Turbohaler® dry powder inhaler. Secondary objectives include investigating the effect on the rate of exacerbations with FF/UMEC/VI compared with budesonide/formoterol, and the safety profile of FF/UMEC/VI compared with budesonide/formoterol. Adverse events of particular interest include pneumonia and cardiovascular risk. Patient perspectives of efficacy and physical activity will also be evaluated versus budesonide/formoterol.

The first, larger study in the phase III programme, known as IMPACT, started in July 2014 to assess whether FF/UMEC/VI can reduce the rate of moderate and severe exacerbations compared with two approved once-daily COPD treatments, Relvar/Breo Ellipta (FF/VI), an ICS/LABA combination, and Anoro Ellipta (UMEC/VI), a LAMA/LABA combination.

Dave Allen, Head, GSK Respiratory Therapy Area Unit, R&D, said: “Triple combination therapy is already a reality for one in three patients with COPD and is often dispensed in different inhalers with differing doses. By providing all three medicine components in a single inhaler we hope to offer more convenient dosing to patients, reduce the risk of exacerbation compared to dual therapy and, as a result, contribute to the improved management of their disease. 

Michael W. Aguiar, Chief Executive Officer of Theravance, added: “With FULFIL, we hope to demonstrate that a once-daily triple combination can reduce exacerbations in patients with COPD and deliver meaningful improvements in lung function and health related quality of life. If successful, a once-daily triple combination would be an important addition to our portfolio of combination respiratory products partnered with GSK including Relvar®/Breo® Ellipta® and Anoro® Ellipta®.”

About the FULFIL study

FULFIL (Lung FUnction and quality of LiFe assessment in COPD with closed trIpLe therapy) is a randomised, double-blind, double-dummy, parallel group multicentre study evaluating once-daily FF/UMEC/VI (100mcg/62.5mcg/25mcg) inhalation powder versus twice-daily budesonide/formoterol (400mcg/12mcg). The study aims to enrol 1,800 patients across approximately 180 study centres globally. 

The co-primary endpoints are: to evaluate the effects of FF/UMEC/VI on lung function and health related quality of life compared with budesonide/formoterol after 24 weeks of treatment. Other endpoints include the effect of FF/UMEC/VI on the annual rate of exacerbations compared with budesonide/formoterol, and the safety profile of FF/UMEC/VI compared with budesonide/formoterol over 24 weeks and 52 weeks of treatment. To provide additional longer term safety data, a sub-set of approximately 400 patients will remain on blinded study treatment for up to a total of 52 weeks.

The closed triple combination of FF/UMEC/VI is not approved for use anywhere in the world.

About COPD

Chronic obstructive pulmonary disease, or 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. COPD-related exacerbations are typically defined as a worsening of symptoms that require medical intervention.1

Long-term exposure to lung irritants that damage the lungs and the airways are usually the cause of COPD1. Cigarette smoke, breathing in second-hand smoke, air pollution, chemical fumes or dust from the environment or workplace can all contribute to COPD1. Most people who have COPD are at least 40 years old when symptoms begin.

Despite improvements in the way COPD is managed it continues to pose a burden to patients and healthcare systems. The World Health Organisation estimates that currently 210 million people in the world have COPD and this number is increasing. It is estimated that over 20% of COPD patients are already prescribed triple combination therapy however no medication is currently available that combines all three components in one device.
