Theravance Biopharma’s Trelegy Ellipta Significantly Benefits COPD Patients in Landmark IMPACT Study

DUBLIN, April 19, 2018 /PRNewswire/ — Theravance Biopharma, Inc. (NASDAQ: TBPH) (“Theravance Biopharma”) today highlighted the publication in the New England Journal of Medicine (NEJM) of the landmark IMPACT study of Trelegy Ellipta in patients with chronic obstructive pulmonary disease (COPD). The IMPACT study is one of the largest trials ever conducted in COPD patients with a history of exacerbation.1 Trelegy Ellipta is the triple combination therapy of fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI) in a single ELLIPTA® inhaler.

Trelegy Ellipta is a product in which Theravance Biopharma has an economic interest in future payments that may be made by GlaxoSmithKline (GSK) or one of its affiliates pursuant to its agreements with Innoviva (formerly Theravance, Inc.). Theravance Biopharma is entitled to receive an 85% economic interest in the royalties paid by GSK on worldwide net sales. Those royalties are upward-tiering from 6.5% to 10%, resulting in cash flows to Theravance Biopharma of approximately 5.5% to 8.5% of worldwide net sales of Trelegy Ellipta.

Trelegy Ellipta is the first treatment to provide a combination of three molecules in a single inhaler that only needs to be taken once a day. The unique combination treatment includes: FF, an inhaled corticosteroid; UMEC, a long-acting muscarinic antagonist (LAMA); and VI, a long-acting beta2-adrenergic agonist (LABA). This combination has been formulated to be delivered once-daily in GSK’s ELLIPTA® dry powder inhaler.

In a press release dated April 18, 2018, GSK and Innoviva announced the publication of the landmark IMPACT study in the NEJM. In the IMPACT study, Trelegy Ellipta achieved superiority to members of two different classes of dual combination therapy, Relvar/Breo (FF/VI) and Anoro (UMEC/VI), on the primary endpoint of reduction in the annual rate of on-treatment moderate/severe exacerbations (p<0.001) and a range of other clinically important outcomes, including lung function and health related quality of life.

Results from additional secondary and other endpoints published in the NEJM include:

  • A statistically significant 34% reduction in COPD hospitalizations (severe exacerbations) for Trelegy compared to Anoro (0.13 vs. 0.19 per year; p<0.001) and a reduction of 13% compared to Relvar/Breo which was not statistically significant (0.13 vs. 0.15; p=0.064).
  • A significant reduction in the risk of on-treatment all-cause mortality was observed for both inhaled corticosteroid containing arms compared to Anoro.
  • A 42.1% reduction in the risk of on-treatment all-cause mortality was observed for Trelegy compared to Anoro (20% vs. 1.88%; p=0.011).

The safety profile of single inhaler triple therapy was consistent with the safety profile of the individual components. The most common adverse events across the treatment groups were viral upper respiratory tract infection, worsening of COPD, upper respiratory tract infection, pneumonia and headache. Consistent with previous studies, the incidence of pneumonia as a serious adverse event was 4%, 4%, and 3% for FF/UMEC/VI, FF/VI and UMEC/VI, respectively.

Trelegy Ellipta is approved in Europe as a maintenance treatment in adult patients with moderate to severe COPD who are not adequately treated by a combination of an ICS and a LABA. The product is also approved for use in the US for the long-term, once-daily, maintenance treatment of COPD patients who are receiving Breo (FF/VI) and require additional bronchodilation or who are receiving Breo and Incruse (UMEC). Regulatory applications for Trelegy Ellipta have been submitted and are undergoing assessments in a number of other countries.

Our research efforts are focused in the areas of inflammation and immunology. Our research goal is to design localized medicines that target diseased tissues, without systemic exposure, in order to maximize patient benefit and minimize risk. These efforts leverage years of experience in developing localized medicines for the lungs to treat respiratory disease. The first potential medicine to emerge from our research focus on immunology and localized treatments is an oral, intestinally restricted pan-Janus kinase (JAK) inhibitor, currently in development to treat a range of inflammatory intestinal diseases. Our pipeline of internally discovered product candidates will continue to evolve with the goal of creating transformational medicines to address the significant needs of patients.
