Theravance Biopharma and Mylan Submit New Drug Application to FDA for Revefenacin (TD-4208) in Adults with Chronic Obstructive Pulmonary Disease

Filing Supported by Positive Results from Two Pivotal Phase 3 Efficacy Studies and One 12-Month Phase 3 Safety Study

DUBLIN and HERTFORDSHIRE, England and PITTSBURGH, Nov. 13, 2017 -- (Healthcare Sales & Marketing Network) -- Theravance Biopharma, Inc. (NASDAQ: TBPH) ("Theravance Biopharma") and Mylan N.V. (NASDAQ, TASE: MYL) ("Mylan") today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for revefenacin (TD-4208), an investigational long-acting muscarinic antagonist (LAMA) as a once-daily, nebulized bronchodilator in development for the treatment of chronic obstructive pulmonary disease (COPD). The NDA is supported by the companies' Phase 3 program for revefenacin, which consisted of two replicate pivotal Phase 3 efficacy studies and a 12-month, open-label, active comparator safety study.

"This submission represents a key step in our efforts to bring the first once-daily nebulized LAMA to the COPD patient community. While a significant number of COPD patients require or prefer nebulized therapy, these same patients currently have no access to a nebulized LAMA, broadly considered the cornerstone of COPD maintenance therapy," said Brett Haumann, MD, Chief Medical Officer at Theravance Biopharma. "We are pleased with the comprehensive data package that was generated through our Phase 3 efficacy and safety studies and look forward to the FDA's review of our NDA."

"We are proud of our collaboration with Theravance Biopharma over the past two years on the development of revefenacin and the quality of our NDA submitted to the FDA," said Mylan President Rajiv Malik. "If approved, this product will further strengthen Mylan's expertise in nebulized respiratory therapies and bolster our commercial presence in the respiratory space. We look forward to our continued work with Theravance Biopharma and the FDA as we progress to final approval."

Theravance Biopharma and Mylan previously reported that in two replicate pivotal Phase 3 efficacy studies, revefenacin demonstrated statistically significant and clinically meaningful improvements as compared to placebo in trough forced expiratory volume in one second (FEV1) and in overall treatment effect on trough FEV1 (OTE FEV1) after 12 weeks of dosing.1 Both doses of revefenacin had comparable rates of adverse events (AEs) to placebo, low rates of serious adverse events (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 adverse events, across both trials and across all treatment groups, were exacerbations, cough, dyspnea and headache. Additionally, the companies have previously announced positive results from the 12-month Phase 3 safety study, which did not identify new safety issues. 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 revefenacin as a once-daily, nebulized bronchodilator for the treatment of patients with COPD that will be compatible with a range of jet nebulizers.

About Theravance Biopharma and Mylan Strategic Collaboration

Theravance Biopharma and Mylan N.V. and their respective affiliates have established a strategic collaboration to develop and commercialize nebulized revefenacin products for COPD and other respiratory diseases. Under the terms of the agreement, Theravance Biopharma is leading the US development program for the revefenacin inhalation solution product, with all costs related to the registrational program reimbursed by Mylan up until the approval of the first new drug application, after which costs will be shared. Mylan is responsible for ex-US development and commercialization. Theravance Biopharma is eligible to receive up to $220 million in development and sales milestone payments, as well as a profit-sharing arrangement with Mylan on US sales and double-digit royalties on ex-US sales. Additionally, Theravance Biopharma retains worldwide rights to revefenacin delivered through other dosage forms, such as a metered dose inhaler or dry powder inhaler (MDI/DPI), and the rights to nebulized revefenacin in China.

About COPD

COPD is a growing and devastating disease that is the third leading cause of death in the U.S.2 An estimated 12.7 million American adults are diagnosed with COPD and an almost equal number are believed to be undiagnosed.3There 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 Revefenacin

Revefenacin (TD-4208) is a novel investigational once-daily nebulized LAMA in Phase 3 development 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, revefenacin has the potential to be a best-in-class once-daily single-agent product for COPD patients who require, or prefer, nebulized therapy. The product'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.

About Theravance Biopharma

Theravance Biopharma is a diversified biopharmaceutical company with the core purpose of creating medicines that help improve the lives of patients suffering from serious illness.

Our pipeline of internally discovered product candidates includes potential best-in-class medicines to address the unmet needs of patients being treated for serious conditions primarily in the acute care setting. VIBATIV® (telavancin), our first commercial product, is a once-daily dual-mechanism antibiotic approved in the U.S., Europe and certain other countries for certain difficult-to-treat infections. Revefenacin (TD-4208) is a long-acting muscarinic antagonist (LAMA) being developed as a potential once-daily, nebulized treatment for chronic obstructive pulmonary disease (COPD). Our neprilysin (NEP) inhibitor program is designed to develop selective NEP inhibitors for the treatment of a range of major cardiovascular and renal diseases, including acute and chronic heart failure, hypertension and chronic kidney diseases, such as diabetic nephropathy. Our research efforts are focused in the areas of inflammation and immunology, with the goal of designing medicines that provide targeted drug delivery to tissues in the lung and intestinal tract in order to maximize patient benefit and minimize risk. The first program to emerge from this research is designed to develop intestinally restricted pan-Janus kinase (JAK) inhibitors for the treatment of a range of inflammatory intestinal diseases.

In addition, we have an economic interest in future payments that may be made by Glaxo Group Limited or one of its affiliates (GSK) pursuant to its agreements with Innoviva, Inc. relating to certain drug development programs, including Trelegy Ellipta (the combination of fluticasone furoate, umeclidinium, and vilanterol in a single ELLIPTA® inhaler, previously referred to as the Closed Triple), currently approved in the US for the treatment of appropriate COPD patients and in development for the treatment of COPD in several other countries. The product is also currently in development for the treatment of asthma.
