Theravance Biopharma Announces FDA Approval of Expanded Label for VIBATIV(R) (telavancin)Updated Label Includes Data Describing VIBATIV Use Against Concurrent Bacteremia in Approved Indications
DUBLIN, IRELAND--(Healthcare Sales & Marketing Network) - Theravance Biopharma, Inc. (NASDAQ: TBPH) ("Theravance Biopharma" or the "Company") today announced that the U.S. Food and Drug Administration (FDA) has approved the Company's supplemental New Drug Application (sNDA) for VIBATIV® (telavancin) to expand the product's label to include data describing the treatment of patients with concurrent Staphylococcus aureus (S. aureus) bacteremia in both of the antibiotic's currently approved indications in the United States. VIBATIV is approved in the U.S. for the treatment of adult patients with hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible isolates of S. aureus when alternative treatments are not suitable. In addition, VIBATIV is approved in the U.S. for the treatment of adult patients with complicated skin & skin structure infections (cSSSI) caused by susceptible isolates of Gram-positive bacteria, including S. aureus, both methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) strains.
"When patients with cSSSI or HABP/VABP present with concurrent bacteremia, their treatment becomes more difficult for healthcare practitioners. With this action by the FDA, we believe an important advance has been made in addressing the unique challenges in this area. The additional data that are now reflected in the VIBATIV label address the use of VIBATIV in cSSSI and HABP/VABP with concurrent bacteremia and we are now implementing a strategy to communicate this information to targeted healthcare practitioners," said Frank Pasqualone, Senior Vice President and Global Head, Acute Care Business at Theravance Biopharma. "With the broader medical need for effective bacteremia treatments in mind, we are also conducting a Phase 3 registrational study of telavancin in primary complicated S. aureus bacteremia, which we expect to complete in late 2017 or early 2018. Should we prove successful with this trial and secure approval in this infection type, VIBATIV would possess the broadest set of indications of any branded anti-MRSA agent."
The sNDA filing was based on the combined data from Theravance Biopharma's previously conducted pivotal trials of VIBATIV in its two approved indications -- cSSSI (ATLAS I and II) and HABP/VABP (ATTAIN I and II). The trials were large, multi-center, multinational, double-blind, randomized Phase 3 clinical studies enrolling and treating 3,370 adult patients, including a portion of patients with concurrent bacteremia. Importantly, these studies involved two of the largest cohorts of patients ever studied in these diseases and included one of the largest cohorts of patients with MRSA infections studied to date.
Expanded VIBATIV Label Data
The data added to the VIBATIV label describe patients with concurrent S. aureus bacteremia in the Phase 3 ATLAS and ATTAIN trials. These include:
- In the all-treated cSSSI patient population with baseline S. aureus bacteremia in the ATLAS I and II trials, clinical cure rates at test-of-cure were 57.1% for VIBATIV-treated patients vs. 54.6% for vancomycin-treated patients.
- In the HABP/VABP patient population with at least one Gram-positive respiratory pathogen at baseline who had concurrent S. aureus bacteremia in the ATTAIN I and II trials, the 28-day all-cause mortality rate was 40.0% for VIBATIV-treated patients vs. 39.5% for vancomycin-treated patients.
About VIBATIV® (telavancin)
VIBATIV® was discovered internally in a research program dedicated to finding new antibiotics for serious infections due to Staphylococcus aureus (S. aureus) and other Gram-positive bacteria, including MRSA and MSSA. VIBATIV is a bactericidal, once-daily, injectable lipoglycopeptide antibiotic with in vitro potency and a dual mechanism of action that both inhibits bacterial cell wall synthesis and disrupts bacterial cell membrane function. The drug's proven efficacy against difficult-to-treat Gram-positive infections has been demonstrated in several large, multinational registrational studies, which involved one of the largest cohorts of patients with S. aureus infections studied to date. Additionally, there is extensive and well-documented evidence of the drug's in vitro potency and in vivo activity against a broad collection of Gram-positive bacterial pathogens, including those that are considered difficult-to-treat and multidrug-resistant. VIBATIV is approved in the U.S. for the treatment of adult patients with hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible isolates of S. aureus when alternative treatments are not suitable. In addition, VIBATIV is approved in the U.S. for the treatment of adult patients with complicated skin & skin structure infections (cSSSI) caused by susceptible isolates of Gram-positive bacteria, including S. aureus, both methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) strains.
VIBATIV is also approved for marketing in Europe, Canada and Russia. Theravance Biopharma plans to market VIBATIV outside the U.S. through a network of partners. To date, the company has secured partners for VIBATIV in the following geographies -- Europe, Canada, Middle East, North Africa, Israel, Russia, China and India.
VIBATIV® Important Safety Information
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.
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.
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.
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.
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.
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.
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.
