Theravance Biopharma Initiates Patient Registry Study For VIBATIV(R) (telavancin)

GEORGE TOWN, GRAND CAYMAN--(Marketwired - February 10, 2015) -

Theravance Biopharma, Inc. (NASDAQ: TBPH) (“Theravance Biopharma” or the “Company”) today announced enrollment of the first patient in the Company’s Telavancin Observational Use Registry (TOUR). The study is designed to assess how VIBATIV® (telavancin), the Company’s proprietary FDA-approved antibiotic, is being used by healthcare practitioners to treat patients. By broadly collecting and examining real-world data related to VIBATIV treatment patterns, clinical effectiveness and safety outcomes in medical practice, the Company aims to create an expansive knowledge base to guide optimal clinical use and future development of the drug.

VIBATIV is a bactericidal, once-daily, injectable lipoglycopeptide antibiotic with in vitro potency and a dual mechanism of action whereby telavancin both inhibits bacterial cell wall synthesis and disrupts bacterial cell membrane function. The drug’s proven efficacy against difficult-to-treat infections has been demonstrated in several large, multinational registrational studies, which involved one of the largest cohorts of patients with methicillin-resistant Staphylococcus aureus (MRSA) infections studied to date. Recently presented study analyses further supplement the extensive and well-documented evidence of the drug’s in vitro potency and in vitro activity against a broad collection of bacterial pathogens, including those that are considered difficult-to-treat and multidrug-resistant.

“We are undertaking this observational use study as an important component of our strategy to enhance our understanding of the clinical use of VIBATIV,” said Frank Pasqualone, Senior Vice President, Development and Operations at Theravance Biopharma. “With the extensive data we collect on how VIBATIV therapy is managed by healthcare practitioners in the clinic, we will be able to further educate the broader healthcare community about the drug’s optimal clinical use.”

TOUR is a multi-center, observational study that will enroll approximately 1,000 patients from about 50 sites in the US. As a non-interventional study, all treatment decisions will be at the discretion of the patient’s healthcare provider prior to patient enrollment. Study patients will have treatment initiated in both hospital-based settings and out-patient infusion sites. In order to qualify for enrollment in TOUR, patients must have received at least one dose of VIBATIV and meet specified inclusion criteria.

Theravance Biopharma believes that results from the patient registry may serve several important objectives including:

• Assisting in optimizing VIBATIV use in patients currently being treated with the drug;

• Assessing the types of patients that are best suited for treatment, potentially highlighting subsets of patients that may be appropriate for treatment with VIBATIV; and

• Illustrating current healthcare practitioners’ patterns of VIBATIV use in combating antibiotic resistance.

“With a number of recent, highly visible developments related to the fight against antibiotic resistance, including a comprehensive call-to-action by President Obama, we believe TOUR is an important and timely study for the anti-infective industry,” stated Rick E Winningham, Chairman and Chief Executive Officer. “Data from this study can support VIBATIV as an essential tool in the antibiotic arsenal of physicians and healthcare practitioners.”

VIBATIV is approved in the US for the treatment of adult patients with hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible isolates of Staphylococcus aureus when alternative treatments are not suitable, and for the treatment of cSSSI caused by susceptible isolates of Gram-positive bacteria, including Staphylococcus aureus, both methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) strains. VIBATIV, which was discovered and developed internally, is a bactericidal, once-daily, injectable lipoglycopeptide antibiotic with in vitro potency and a dual mechanism of action whereby telavancin both inhibits bacterial cell wall synthesis and disrupts bacterial cell membrane function.

About VIBATIV® (telavancin)

VIBATIV was discovered by Theravance, Inc. in a research program dedicated to finding new antibiotics for serious infections due to Staphylococcus aureus and other Gram-positive bacteria, including MRSA. VIBATIV is a bactericidal, once-daily, injectable lipoglycopeptide antibiotic with in vitro potency and a dual mechanism of action whereby telavancin both inhibits bacterial cell wall synthesis and disrupts bacterial cell membrane function. VIBATIV is approved in the US for the treatment of adult patients with HABP/VABP when alternative treatments are not suitable and for cSSSI caused by susceptible isolates of Gram-positive bacteria, including Staphylococcus aureus, both methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) strains.

Theravance Biopharma plans to market VIBATIV in markets outside the United States where the drug is approved through a network of partners.

In Europe, VIBATIV is indicated for the treatment of adults with nosocomial pneumonia (NP) including ventilator associated pneumonia, known or suspected to be caused by MRSA. VIBATIV should be used only in situations where it is known or suspected that other alternatives are not suitable. VIBATIV is not currently indicated for the treatment of cSSSI in Europe.

Clinigen Group holds the commercial rights to market and distribute VIBATIV in Europe.

Theravance Biopharma also has partners in the following geographies -- Canada, Middle East, North Africa, Israel, and Russia. Discussions continue regarding potential partnering relationships in other parts of the world.

VIBATIV® Important Safety Information (US)

Mortality

Patients with pre-existing moderate/severe renal impairment (CrCl ≤ 50 mL/min) who were treated with VIBATIV® for hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia had increased mortality observed versus vancomycin. Use of VIBATIV® in patients with pre-existing moderate/severe renal impairment (CrCl ≤ 50 mL/min) should be considered only when the anticipated benefit to the patient outweighs the potential risk.

Nephrotoxicity

New onset or worsening renal impairment occurred in patients who received VIBATIV®. Renal adverse events were more likely to occur in patients with baseline comorbidities known to predispose patients to kidney dysfunction and in patients who received concomitant medications known to affect kidney function. Monitor renal function in all patients receiving VIBATIV® prior to initiation of treatment, during treatment, and at the end of therapy. If renal function decreases, the benefit of continuing VIBATIV® versus discontinuing and initiating therapy with an alternative agent should be assessed.

Fetal Risk

Women of childbearing potential should have a serum pregnancy test prior to administration of VIBATIV®. Avoid use of VIBATIV® during pregnancy unless the potential benefit to the patient outweighs the potential risk to the fetus. Adverse developmental outcomes observed in three animal species at clinically relevant doses raise concerns about potential adverse developmental outcomes in humans. If not already pregnant, women of childbearing potential should use effective contraception during VIBATIV® treatment.

Contraindication

Intravenous unfractionated heparin sodium is contraindicated with VIBATIV® administration due to artificially prolonged activated partial thromboplastin time (aPTT) test results for up to 18 hours after VIBATIV® administration.

VIBATIV® is contraindicated in patients with a known hypersensitivity to the drug.

Hypersensitivity Reactions

Serious and potentially fatal hypersensitivity reactions, including anaphylactic reactions, may occur after first or subsequent doses. VIBATIV® should be used with caution in patients with known hypersensitivity to vancomycin.

Geriatric Use

Telavancin is substantially excreted by the kidney, and the risk of adverse reactions may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection in this age group.

Infusion Related Reactions

VIBATIV® is a lipoglycopeptide antibacterial agent and should be administered over a period of 60 minutes to reduce the risk of infusion-related reactions. Rapid intravenous infusions of the glycopeptide class of antimicrobial agents can cause “Red-man Syndrome” like reactions including: flushing of the upper body, urticaria, pruritus, or rash.

QTc Prolongation

Caution is warranted when prescribing VIBATIV® to patients taking drugs known to prolong the QT interval. In a study involving healthy volunteers, VIBATIV® prolonged the QTc interval. Use of VIBATIV® should be avoided in patients with congenital long QT syndrome, known prolongation of the QTc interval, uncompensated heart failure, or severe left ventricular hypertrophy.

Most Common Adverse Reactions

The most common adverse reactions (greater than or equal to 10% of patients treated with VIBATIV®) were diarrhea, taste disturbance, nausea, vomiting, and foamy urine.
