DUBLIN and HERTFORDSHIRE, England and PITTSBURGH, Oct. 11, 2018 /PRNewswire/ -- Theravance Biopharma, Inc. (NASDAQ: TBPH) ("Theravance Biopharma") and Mylan N.V. (NASDAQ: MYL) ("Mylan") today announced that positive new data from multiple studies of YUPELRI^™ (revefenacin) inhalation solution were presented at the 2018 CHEST annual meeting, which was held in San Antonio, Texas on October 6-10, 2018. YUPELRI is an investigational long-acting muscarinic antagonist (LAMA) currently under review by the U.S. Food and Drug Administration (FDA) for the treatment of chronic obstructive pulmonary disease (COPD). The Prescription Drug User Fee Act (PDUFA) date for YUPELRI is November 13, 2018. If approved, YUPELRI would be the first and only once-daily, long-acting nebulized bronchodilator for the treatment of COPD. YUPELRI is designed to be compatible with any standard jet nebulizer.

Details from the three CHEST presentations are as follows:

Efficacy in COPD Patients with Suboptimal PIFR – YUPELRI vs. Tiotropium

Researchers presented new data from a randomized, double-blinded study comparing the efficacy of YUPELRI to tiotropium in patients with moderate to very severe COPD and suboptimal peak inspiratory flow rates (PIFR) (< 60 L/min). 207 subjects were enrolled and randomized to receive either YUPELRI (175 mcg once daily) or tiotropium once daily for 28 days. Efficacy assessments included forced expiratory volume in one second (FEV₁) and forced vital capacity (FVC).

In the intent-to-treat population, the YUPELRI group showed improvements in trough FEV₁ and trough FVC on day 29 compared with tiotropium group; however, these differences did not reach statistical significance.  In the prespecified analysis of subjects with severe to very severe COPD (FEV₁ < 50% predicted), which represented approximately 80% of the study population, YUPELRI demonstrated statistically significant improvements in trough FEV₁ (p = 0.025) and FVC (p = 0.034) as compared to tiotropium. No new adverse events (AEs) were noted for either YUPELRI or tiotropium, and there were numerically fewer AEs observed in patients receiving YUPELRI (11.7%) compared to patients receiving tiotropium (37.5%).

"These results are noteworthy as this represents the first head-to-head study conducted between tiotropium dry powder via Handihaler and a nebulized treatment, such as YUPELRI. Furthermore, by focusing on COPD patients with suboptimal PIFR, the study provides important context around a patient group believed to be well positioned to benefit from once-daily, long-acting nebulized therapy," said Donald A. Mahler, M.D., emeritus professor of medicine at the Geisel School of Medicine at Dartmouth College and lead author of the study. "The statistically significant improvements in trough FEV₁ and FVC shown for YUPELRI as compared to tiotropium in the severe to very severe subpopulation of patients with FEV₁ < 50% predicted suggest that these individuals may be best suited for nebulized therapy. Further confirmation incorporating the learnings from this study is recommended."

Efficacy in COPD Patients with Markers of More Severe Disease – Phase 3 Program Data Analysis

Researchers presented prespecified analyses of data from the YUPELRI Phase 3 program, highlighted by the demonstration of efficacy advantages for YUPELRI dosed at 175 mcg once daily compared to YUPELRI dosed at 88 mcg once daily in four subgroups of patients categorized as being at risk of COPD exacerbations based on markers of more severe COPD. The subgroups included patients on concomitant long-acting beta agonists (LABA), patients on inhaled corticosteroids (ICS), elderly patients (aged > 65 years in the 12-week efficacy trials, aged ≥ 65 in the 12-month safety trial) and patients classified as Global Initiative for Chronic Obstructive Lung Disease Category D (GOLD D).

Pooled data from the two replicate 12-week pivotal Phase 3 efficacy trials demonstrated that YUPELRI dosed at 175 mcg once daily produced greater improvements in trough FEV₁ than YUPELRI dosed at 88 mcg once daily in each of the four analyzed subgroups. These efficacy trends favoring the 175 mcg once daily dose in the subgroups are consistent with those reported for the entire intent-to-treat population in the two Phase 3 efficacy trials.

Additionally, data from the 12-month Phase 3 safety trial demonstrated that YUPELRI dosed at 175 mcg once daily produced greater improvements in trough FEV₁ than YUPELRI dosed at 88 mcg once daily in the LABA subgroup. The YUPELRI doses were equally effective at improving trough FEV₁ in the ICS and elderly subgroups in the 12-month safety study.

Cardiovascular Safety: Review of Randomized, Controlled Trial Data, Including Phase 3 Program

Researchers conducted a review of cardiovascular (CV) safety data from four clinical studies of YUPELRI including the two replicate 12-week pivotal Phase 3 efficacy trials, the 12-month Phase 3 safety trial and a Phase 1 QT study in healthy subjects. The data analysis demonstrated that once-daily YUPELRI dosed for up to 52 weeks did not prolong QT interval or increase risk of major adverse cardiac events (MACE). Detailed findings include:

• Single YUPELRI doses of up 700 mcg did not have a clinically meaningful effect on cardiac repolarization (QTcF) in healthy patients.
• In the two Phase 3 efficacy studies in patients with moderate to very severe COPD, incidences of prolonged QTcF interval (> 450 msec in males, > 470 msec in females) were similar for placebo and YUPELRI dosed at 88 mcg once daily and 175 mcg once daily.
• In the Phase 3 safety trial in patients with moderate to very severe COPD, incidences of prolonged QTcF interval were similar for YUPELRI dosed at 175 mcg once daily and tiotropium, and slightly lower for YUPELRI dosed at 88 mcg once daily.
• There was no observed increased risk of MACE identified for either YUPELRI dose compared to tiotropium or placebo in the three Phase 3 clinical trials. Only one MACE seen in the Phase 3 program was considered possibly/probably related to YUPELRI.

Theravance Biopharma and Mylan previously reported that in two replicate pivotal Phase 3 efficacy studies, YUPELRI demonstrated statistically significant and clinically meaningful improvements as compared to placebo in trough FEV₁ and in overall treatment effect on trough FEV₁ (OTE FEV₁) after 12 weeks of dosing.¹ YUPELRI had comparable rates of AEs to placebo, low rates of serious AEs (SAEs), and no clinically meaningful differences in blood parameters or electrocardiogram (ECG) data, across all treatment groups (active and placebo). As previously reported, the most commonly reported AEs, across both trials and across all treatment groups, were exacerbations, cough, dyspnea and headache. Additionally, the companies completed a 12-month Phase 3 safety study in which no new safety issues were identified. Rates of AEs and SAEs in the study were low and comparable to those seen in the standard of care treatment arm.

Theravance Biopharma and its affiliates have partnered with Mylan and its affiliates on the development and commercialization of nebulized revefenacin products for COPD and other respiratory diseases. The companies are developing YUPELRI as a once-daily, nebulized bronchodilator for the treatment of patients with COPD, to be compatible with any standard jet nebulizer.

About COPD

COPD is a growing and devastating disease that is the third leading cause of death in the U.S.² Nearly 15.7 million Americans (6.4%) report that they have been diagnosed with COPD and more are believed to be undiagnosed.³ There were more than 700,000 hospital discharges related to COPD in the U.S. reported in 2010. The costs of managing COPD in the U.S. were estimated to be nearly $50 billion in 2010, including $29.5 billion in direct healthcare expenditures, $8 billion in indirect morbidity costs and $12.4 billion in indirect mortality costs.³

About YUPELRI

YUPELRI (revefenacin) inhalation solution is a novel investigational once-daily nebulized LAMA under FDA review for the treatment of moderate to very severe COPD. Market research by Theravance Biopharma indicates approximately 9% of the treated COPD patients in the U.S. use nebulizers for ongoing maintenance therapy.⁴ LAMAs are a cornerstone of maintenance therapy for COPD and, if approved, YUPELRI would be the first and only once-daily, long-acting single-agent product for COPD patients who require, or prefer, nebulized therapy. YUPELRI's stability in both metered dose inhaler and dry powder device formulations suggest that this LAMA could also serve as a foundation for novel handheld combination products.
