Theravance Biopharma Entitled to Receive 85% Economic Interest in Trelegy Ellipta Royalties Paid by GlaxoSmithKline as Part of Agreement with Innoviva
DUBLIN, Sept. 20, 2017 /PRNewswire/ -- Theravance Biopharma, Inc. (NASDAQ: TBPH) ("Theravance Biopharma") today highlighted that GlaxoSmithKline plc (GSK) and Innoviva, Inc. (Innoviva) have reported positive headline results from the landmark Phase 3 IMPACT study of Trelegy Ellipta, the first and only FDA approved once-daily single inhaler triple therapy comprising an inhaled corticosteroid (ICS), long-acting muscarinic antagonist (LAMA) and long-acting beta agonist (LABA). Trelegy Ellipta is a drug development program for which Theravance Biopharma has an economic interest in future payments that may be made by 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%. Theravance Biopharma is not responsible for any costs related to Trelegy Ellipta.
Trelegy Ellipta (fluticasone furoate/umeclidinium/vilanterol, FF/UMEC/VI) is approved in the US for the long-term, once-daily, maintenance treatment of patients with chronic obstructive pulmonary disease (COPD) who are receiving Breo (fluticasone furoate/vilanterol, FF/ VI) and require additional bronchodilation or who are receiving Breo and Incruse (umeclidinium, UMEC).
In an announcement dated September 20, 2017, GSK and Innoviva stated the IMPACT study, which involved 10,355 patients, met its primary endpoint demonstrating statistically significant reductions in the annual rate of on-treatment moderate/severe exacerbations for FF/UMEC/VI (100/62.5/25mcg) when compared with two, once-daily dual COPD therapies from GSK's existing portfolio. The study showed a:
- 15% reduction for FF/UMEC/VI compared with Relvar/Breo Ellipta (FF/VI,100/25mcg); 0.91 vs 1.07 per year; p<0.001
- 25% reduction for FF/UMEC/VI compared with Anoro Ellipta (UMEC/VI, 62.5/25mcg); 0.91 vs 1.21 per year; p<0.001
In addition, statistically significant improvements were observed across all pre-specified key secondary endpoints and associated treatment comparisons:
- Change from baseline trough FEV1 at week 52 for FF/UMEC/VI compared with FF/VI was 97mL; p<0.001 and for FF/UMEC/VI compared with UMEC/VI was 54mL; p<0.001
- Change from baseline St. George's Respiratory Questionnaire at week 52 for FF/UMEC/VI compared with FF/VI was -1.8 units; p<0.001 and for FF/UMEC/VI compared with UMEC/VI was -1.8 units; p<0.001
- Analysis of time to first on-treatment moderate/severe COPD exacerbation demonstrated a 14.8% reduction in risk for FF/UMEC/VI compared with FF/VI; p<0.001, and a 16.0% reduction in risk for FF/UMEC/VI compared with UMEC/VI; p<0.001
GSK and Innoviva also noted that based on review of the headline data, the safety profile of FF/UMEC/VI was consistent with the known profile of the individual medicines and their dual combinations. 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. The incidences of the most frequent serious adverse events were worsening of COPD: 11%, 11% and 13% for FF/UMEC/VI, FF/VI and UMEC/VI, respectively; and pneumonia: 4%, 4% and 3% for FF/UMEC/VI, FF/VI and UMEC/VI, respectively. According to GSK and Innoviva, full results from the IMPACT study will be presented at upcoming scientific meetings and in peer-reviewed publications.
The InforMing the PAthway of COPD Treatment (IMPACT) study was a randomized, double-blind, 3-arm parallel group, multicenter study evaluating FF/UMEC/VI (100mcg/62.5mcg/25mcg) versus FF/VI (100mcg/25mcg) and UMEC/VI (62.5mcg/25mcg), all given once daily via the Ellipta dry powder inhaler. The total duration of the study was approximately 55 weeks consisting of a 2-week run-in period, 52-week treatment period and a 1-week safety follow-up period. Patients had moderate to very severe symptomatic COPD with a history of exacerbation in the prior 12 months. In the study, 10,355 patients were treated in over 1,035 study centers globally.
The primary efficacy endpoint was the annual rate of on-treatment moderate and severe exacerbations. This was compared for FF/UMEC/VI versus FF/VI and, FF/UMEC/VI versus UMEC/VI. Other endpoints included lung function and patient reported outcomes, including health related quality of life measures.
