Vibativ Prescribing 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 (HABP/VABP) 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[see Warnings and Precautions ].
- Nephrotoxicity: New onset or worsening renal impairment has occurred. Monitor renal function in all patients[see Warnings and Precautions ].
- Embryofetal Toxicity: VIBATIV may cause fetal harm. In animal reproduction studies, adverse developmental outcomes were observed in 3 animal species at clinically relevant doses. Verify pregnancy status in females of reproductive potential prior to initiating VIBATIV. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with VIBATIV and for 2 days after the final dose[see Warnings and Precautions , and Use in Specific Populations ].
Complicated Skin and Skin Structure Infections
VIBATIV is indicated for the treatment of adult patients with complicated skin and skin structure infections (cSSSI) caused by susceptible isolates of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-susceptible and -resistant isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus anginosus group (includes S. anginosus, S. intermedius, and S. constellatus), or Enterococcus faecalis (vancomycinsusceptible isolates only).
HABP/VABP
VIBATIV is indicated for the treatment of adult patients with hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP), caused by susceptible isolates of Staphylococcus aureus (both methicillin-susceptible and -resistant isolates). VIBATIV should be reserved for use when alternative treatments are not suitable.
Usage
Combination therapy may be clinically indicated if the documented or presumed pathogens include Gram-negative organisms.
Appropriate specimens for bacteriological examination should be obtained in order to isolate and identify the causative pathogens and to determine their susceptibility to telavancin. VIBATIV may be initiated as empiric therapy before results of these tests are known.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of VIBATIV and other antibacterial drugs, VIBATIV should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Complicated Skin and Skin Structure Infections
The recommended dosing for VIBATIV is 10 mg/kg administered over a 60-minute period in patients ≥18 years of age by intravenous infusion once every 24 hours for 7 to 14 days. The duration of therapy should be guided by the severity and site of the infection and the patient's clinical progress.
Hospital-Acquired Bacterial Pneumonia/Ventilator-Associated Bacterial Pneumonia (HABP/VABP)
The recommended dosing for VIBATIV is 10 mg/kg administered over a 60-minute period in patients ≥18 years of age by intravenous infusion once every 24 hours for 7 to 21 days. The duration of therapy should be guided by the severity of the infection and the patient's clinical progress.
Patients with Renal Impairment
Because telavancin is eliminated primarily by the kidney, a dosage adjustment is required for patients whose creatinine clearance is ≤50 mL/min, as listed in Table 1 [see Clinical Pharmacology ].

There is insufficient information to make specific dosage adjustment recommendations for patients with end-stage renal disease (CrCl <10 mL/min), including patients undergoing hemodialysis.
Preparation and Administration
750 mg vial: Reconstitute the contents of a VIBATIV 750 mg vial with 45 mL of 5% Dextrose Injection, USP; Sterile Water for Injection, USP; or 0.9% Sodium Chloride Injection, USP. The resultant solution has a concentration of 15 mg/mL (total volume of approximately 50.0 mL).
To minimize foaming during product reconstitution, allow the vacuum of the vial to pull the diluent from the syringe into the vial. Do not forcefully inject the diluent into the vial. Do not forcefully shake the vial and do not shake final infusion solution.
The following formula can be used to calculate the volume of reconstituted VIBATIV solution required to prepare a dose:
Telavancin dose (mg) = 10 mg/kg or 7.5 mg/kg x patient weight (in kg) (see Table 1)
| Volume of reconstituted solution (mL) = | Telavancin dose (mg) |
| 15 mg/mL |
For doses of 150 to 800 mg, the appropriate volume of reconstituted solution must be further diluted in 100 to 250 mL prior to infusion. Doses less than 150 mg or greater than 800 mg should be further diluted in a volume resulting in a final concentration of 0.6 to 8 mg/mL. Appropriate infusion solutions include: 5% Dextrose Injection, USP; 0.9% Sodium Chloride Injection, USP; or Lactated Ringer's Injection, USP. The dosing solution should be administered by intravenous infusion over a period of 60 minutes.
Reconstitution time is generally under 2 minutes, but can sometimes take up to 20 minutes. Mix thoroughly to reconstitute and check to see if the contents have dissolved completely. Parenteral drug products should be inspected visually for particulate matter prior to administration. Discard the vial if the vacuum did not pull the diluent into the vial.
Since no preservative or bacteriostatic agent is present in this product, aseptic technique must be used in preparing the final intravenous solution. Studies have shown that the reconstituted solution in the vial should be used within 12 hours when stored at room temperature or within 7 days under refrigeration at 2 to 8°C (36 to 46°F). The diluted (dosing) solution in the infusion bag should be used within 12 hours when stored at room temperature or used within 7 days when stored under refrigeration at 2 to 8°C (36 to 46°F). However, the total time in the vial plus the time in the infusion bag should not exceed 12 hours at room temperature and 7 days under refrigeration at 2 to 8°C (36 to 46°F). The diluted (dosing) solution in the infusion bag can also be stored at -30 to -10°C (-22 to 14°F) for up to 32 days.
VIBATIV is administered intravenously. Because only limited data are available on the compatibility of VIBATIV with other IV substances, additives or other medications should not be added to VIBATIV single-dose vials or infused simultaneously through the same IV line. If the same intravenous line is used for sequential infusion of additional medications, the line should be flushed before and after infusion of VIBATIV with 5% Dextrose Injection, USP; 0.9% Sodium Chloride Injection, USP; or Lactated Ringer's Injection, USP.
VIBATIV is supplied in single-dose vials containing 750 mg telavancin as a sterile, lyophilized powder.
Pregnancy
Risk Summary
Based on findings in animal reproduction studies, VIBATIV may cause fetal harm. There are no available data on VIBATIV use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In embryo-fetal development studies in rats, rabbits, and minipigs, telavancin demonstrated the potential to cause limb and skeletal malformations when given intravenously during the period of organogenesis at doses providing approximately 1- to 2-fold the human exposure at the maximum recommended clinical dose (see Data). Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data
Animal Data
In embryo-fetal development studies in rats, rabbits, and minipigs, telavancin demonstrated the potential to cause limb and skeletal malformations when given intravenously during the period of organogenesis at doses up to 150, 45, or 75 mg/kg/day, respectively. These doses resulted in exposure levels approximately 1- to 2-fold the human exposure (AUC) at the maximum recommended clinical dose. Malformations observed at <1% (but absent or at lower rates in historical or concurrent controls), included brachymelia (rats and rabbits), syndactyly (rats, minipigs), adactyly (rabbits), and polydactyly (minipigs). Additional findings in rabbits included flexed front paw and absent ulna, and in the minipigs included misshapen digits and deformed front leg. Fetal body weights were decreased in rats.
In a prenatal/perinatal development study, pregnant rats received intravenous telavancin at up to 150 mg/kg/day (approximately the same AUC as observed at the maximum clinical dose) from the start of organogenesis through lactation. Offspring showed decreases in fetal body weight and an increase in the number of stillborn pups. Brachymelia was also observed. Developmental milestones and fertility of the pups were unaffected.
Lactation
Risk Summary
There are no data on the presence of telavancin in human milk, the effects on the breastfed child, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for VIBATIV and any potential adverse effects on the breastfed child from VIBATIV or from the underlying maternal conditions.
Females and Males of Reproductive Potential
Pregnancy Testing
Verify pregnancy status in females of reproductive potential prior to initiating VIBATIV.
Contraception
Females
VIBATIV may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ]. Advise females of reproductive potential to use effective contraception during treatment and for 2 days after the final dose.
Infertility
Males
Based on findings in rats, VIBATIV may impair male fertility [see Nonclinical Toxicology ]. The effect on fertility was reversible in rats.
Pediatric Use
The safety and effectiveness of VIBATIV have not been established in pediatric patients. In particular, there is a concern for poor clinical outcomes in pediatric patients less than one year of age due to immature renal function. Increased mortality in adult patients with HABP/VABP and renal impairment and decreased clinical response in adults with cSSSI and renal impairment were observed [see Boxed Warning and Warnings and Precautions ].
Geriatric Use
Of the 929 patients treated with VIBATIV at a dose of 10 mg/kg once daily in clinical trials of cSSSI, 174 (19%) were ≥65 years of age and 87 (9%) were ≥75 years of age. In the cSSSI trials, lower clinical cure rates were observed in patients ≥65 years of age compared with those <65 years of age. Overall, treatment-emergent adverse events occurred with similar frequencies in patients ≥65 (75% of patients) and <65 years of age (83% of patients). Fifteen of 174 (9%) patients ≥65 years of age treated with VIBATIV had adverse events indicative of renal impairment compared with 16 of 755 (2%) patients <65 years of age [see Warnings and Precautions , Clinical Trials ].
Of the 749 HABP/VABP patients treated with VIBATIV at a dose of 10 mg/kg once daily in clinical trials of HABP/VABP, 397 (53%) were ≥65 years of age and 230 (31%) were ≥75 years of age. Treatment-emergent adverse events as well as deaths and other serious adverse events occurred more often in patients ≥65 years of age than in those <65 years of age in both treatment groups.
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.
The mean plasma AUC values of telavancin were similar in healthy young and elderly subjects. Dosage adjustment for elderly patients should be based on renal function [see Dosage and Administration , Clinical Pharmacology ].
Patients with Renal Impairment
The HABP/VABP and cSSSI trials included patients with normal renal function and patients with varying degrees of renal impairment. Patients with underlying renal dysfunction or risk factors for renal dysfunction had a higher incidence of renal adverse events [see Warnings and Precautions ].
In the HABP/VABP studies higher mortality rates were observed in the VIBATIV-treated patients with baseline CrCl ≤50 mL/min. Use of VIBATIV in patients with pre-existing moderate/severe renal impairment should be considered only when the anticipated benefit to the patient outweighs the potential risk [see Warnings and Precautions ( 5.1,)].
VIBATIV-treated patients in the cSSSI studies with baseline creatinine clearance ≤50 mL/min had lower clinical cure rates. Consider these data when selecting antibacterial therapy in patients with baseline moderate/severe renal impairment (CrCl ≤50 mL/min) [see Warnings and Precautions , Clinical Pharmacology ].
Hydroxypropyl-beta-cyclodextrin is excreted in urine and may accumulate in patients with renal impairment. Serum creatinine should be closely monitored and, if renal toxicity is suspected, an alternative agent should be considered [see Warnings and Precautions , Clinical Pharmacology ].
Patients with Hepatic Impairment
The HABP/VABP and cSSSI trials included patients with normal hepatic function and with hepatic impairment. No dosage adjustment is recommended in patients with mild or moderate hepatic impairment [see Clinical Pharmacology ].
Intravenous Unfractionated Heparin Sodium
Use of intravenous unfractionated heparin sodium is contraindicated with VIBATIV administration because the activated partial thromboplastin time (aPTT) test results are expected to be artificially prolonged for 0 to 18 hours after VIBATIV administration [see Warnings and Precautions and Drug Interactions ].
Known Hypersensitivity to VIBATIV
VIBATIV is contraindicated in patients with known hypersensitivity to telavancin.
