Theravance Biopharma and Mylan to Present New Data on YUPELRI® (revefenacin) at the 2019 CHEST Annual Meeting

Study provides data on YUPELRI when administered with formoterol in patients with COPD
Additional data characterizes baseline demographics and clinical characteristics of patients with COPD and suboptimal PIFR from clinical trials of YUPELRI

DUBLIN and HERTFORDSHIRE, England and PITTSBURGH, Oct. 21, 2019 /PRNewswire/ -- Theravance Biopharma, Inc. (NASDAQ: TBPH) ("Theravance Biopharma") and Mylan N.V. (NASDAQ: MYL) ("Mylan") today announced that data from studies of YUPELRI® (revefenacin) inhalation solution will be presented at CHEST 2019, the annual meeting of the American College of Chest Physicians, on Oct. 22 in New Orleans, LA. Data will include results from a phase 3b trial on YUPELRI when given before or combined with Perforomist® (formoterol fumarate) inhalation solution via nebulization in patients with chronic obstructive pulmonary disease (COPD). In addition, data from two phase 3 trials will be presented that analyzed the predictors of suboptimal peak inspiratory flow rate (sPIFR) in patients with COPD.

YUPELRI and PERFOROMIST are indicated for the maintenance treatment of COPD. Neither product should be initiated in patients with acutely deteriorating COPD. YUPELRI should be used with caution in patients with narrow angle glaucoma or in patients with prostatic hyperplasia or bladder-neck obstruction. PERFOROMIST should not be used as monotherapy for asthma due to an association with asthma related death. See the full prescribing information for complete information about these products.

Details of the presentations at CHEST 2019 are as follows:

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. YUPELRI is a once-daily, nebulized bronchodilator for the maintenance treatment of patients with COPD and is compatible with any standard jet nebulizer connected to a mouthpiece.

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. Theravance Biopharma is eligible to receive up to $259 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).

About COPD
COPD is a growing and devastating disease that is the third leading cause of death in the U.S.1 Nearly 15.7 million Americans (6.4%) report that they have been diagnosed with COPD and more are believed to be undiagnosed.2 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.2

YUPELRI® (revefenacin) inhalation solution is a once-daily nebulized LAMA approved for the maintenance treatment of COPD in the U.S. Market research by Theravance Biopharma indicates approximately 9% of the treated COPD patients in the U.S. use nebulizers for ongoing maintenance therapy.3 LAMAs are a cornerstone of maintenance therapy for COPD and YUPELRI is positioned as a first-in-class once-daily single-agent bronchodilator 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.

YUPELRI is a registered trademark of Mylan N.V.

Important Safety Information
YUPELRI is contraindicated in patients with hypersensitivity to revefenacin or any component of this product.

YUPELRI should not be initiated in patients during acutely deteriorating or potentially life-threatening episodes of COPD, or for the relief of acute symptoms, i.e., as rescue therapy for the treatment of acute episodes of bronchospasm. Acute symptoms should be treated with an inhaled short-acting beta2-agonist.

As with other inhaled medicines, YUPELRI can produce paradoxical bronchospasm that may be life-threatening. If paradoxical bronchospasm occurs following dosing with YUPELRI, it should be treated immediately with an inhaled, short-acting bronchodilator. YUPELRI should be discontinued immediately and alternative therapy should be instituted.

YUPELRI should be used with caution in patients with narrow-angle glaucoma. Patients should be instructed to immediately consult their healthcare provider if they develop any signs and symptoms of acute narrow-angle glaucoma, including eye pain or discomfort, blurred vision, visual halos or colored images in association with red eyes from conjunctival congestion and corneal edema.

Worsening of urinary retention may occur. Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction and instruct patients to contact a healthcare provider immediately if symptoms occur.

Immediate hypersensitivity reactions may occur after administration of YUPELRI. If a reaction occurs, YUPELRI should be stopped at once and alternative treatments considered.

The most common adverse reactions occurring in clinical trials at an incidence greater than or equal to 2% in the YUPELRI group, and higher than placebo, included cough, nasopharyngitis, upper respiratory infection, headache and back pain.

Coadministration of anticholinergic medicines or OATP1B1 and OATP1B3 inhibitors with YUPELRI is not recommended.

YUPELRI is not recommended in patients with any degree of hepatic impairment.
