Telavancin


General


Pronunciation

(tel a VAN sin)


Brand Names: U.S.

  • Vibativ

Indications


Use: Labeled Indications

Complicated skin and skin structure infections: Treatment of complicated skin and skin structure infections caused by susceptible gram-positive organisms including methicillin-susceptible or -resistant Staphylococcus aureus, vancomycin-susceptible Enterococcus faecalis, and Streptococcus pyogenes, Streptococcus agalactiae, or Streptococcus anginosus group

Hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP): Treatment of HABP/VABP caused by susceptible isolates of Staphylococcus aureus when alternative treatments are not appropriate


Contraindications


Hypersensitivity to telavancin or any component of the formulation; concomitant use of intravenous unfractionated heparin


ALERT: U.S. Boxed Warning

Moderate to severe renal impairment:

Patients with preexisting moderate to severe renal impairment (creatinine clearance [CrCl] 50 mL/minute or less) who were treated with telavancin for hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia had increased mortality observed versus vancomycin. Consider use of telavancin in patients with preexisting moderate to severe renal impairment (CrCl 50 mL/minute or less) only when the anticipated benefit to the patient outweighs the potential risk.

Nephrotoxicity:

New-onset or worsening renal impairment has occurred. Monitor renal function in all patients.

Fetal risk:

Women of childbearing potential should have a serum pregnancy test prior to administration. Avoid use during pregnancy unless the potential benefit to the patient outweighs the potential risk to the fetus. Adverse developmental outcomes observed in 3 animal species at clinically relevant doses raise concerns about potential adverse developmental outcomes in humans.

Reconstitution

Hazardous agent; use appropriate precautions for handling and disposal (NIOSH 2014 [group 3]).

Reconstitute 250 mg vial with 15 mL of D5W, NS, or SWFI to yield 15 mg/mL (total volume of ~17 mL). Reconstitute 750 mg vial with 45 mL of of D5W, NS, or SWFI to yield 15 mg/mL (total volume of ~50 mL). Allow vacuum to pull the diluent into the vial; discard vial if this did not occur. Reconstitution generally takes <2 minutes, although may take up to 20 minutes. Do not shake the vial or final solution for infusion. Prior to administration, dilute dose in 100 to 250 mL D5W, LR, or NS to a final concentration of 0.6 to 8 mg/mL.


Administration

Administer IV over 60 minutes. Other medications should not be infused simultaneously through the same IV line. When the same intravenous line is used for sequential infusion of other medications, flush line with D5W, LR, or NS before and after infusing telavancin.

Red-man syndrome may occur if the infusion is too rapid. It is not an allergic reaction, but may be characterized by hypotension and/or a maculopapular rash appearing on the face, neck, trunk, and/or upper extremities. If this should occur, discontinuing or slowing the infusion rate may eliminate these reactions.

Hazardous agent; use appropriate precautions for handling and disposal (NIOSH 2014 [group 3]).


Storage

Store intact vials at 2 ‚ °C to 8 ‚ °C (35 ‚ °F to 46 ‚ °F); excursions permitted up to 25 ‚ °C (77 ‚ °F); avoid excess heat. Note: Vials contain no bacteriostatic agent. Reconstituted solution in the vial should be used within 12 hours at room temperature or 7 days refrigerated; solutions admixed for infusion in NS, LR, or D5W are stable at room temperature for 12 hours or under refrigeration for 7 days. Total time in vial plus time in infusion bag should not exceed 12 hours at room temperature or 7 days if refrigerated at 2 ‚ °C to 8 ‚ °C (35 ‚ °F to 46 ‚ °F). Solutions admixed for infusion can also be stored at -30 ‚ °C to -10 ‚ °C (-22 ‚ °F to 14 ‚ °F) for ≤32 days.

Monitoring Parameters

Renal function (prior to start, every 48-72 hours; more frequently if indicated, and following therapy), pregnancy test


Lab Test Interferences


Test Interactions

Interferes with the following coagulation assessments when using samples drawn 18 hours or less after telavancin administration (causes artificially increased clotting times): PT, INR, aPTT, ACT, Xa (coagulation based assay). Collect blood samples for these coagulation tests as close as possible prior to administration of the next dose of telavancin, use a non-phospholipid dependent coagulation test (eg, bleeding time, factor Xa [chromogenic assay], platelet aggregation study, thrombin time), or select an alternative anticoagulant not requiring aPTT monitoring; concomitant use of telavancin and IV unfractionated heparin is contraindicated.

Interferes with urine protein via qualitative dipstick and quantitative dye methods.

Warnings/Precautions


Special Populations: Renal Function Impairment

The mean AUC values were approximately 13%, 29%, and 118% higher for subjects with CrCl >50-80 mL/minute, CrCl 30-50 mL/minute, and CrCl ≤30 mL/minute, respectively when compared with subjects with healthy renal function.


Warnings/Precautions

Concerns related to adverse effects:

- Anaphylaxis/hypersensitivity reactions: Serious hypersensitivity reactions, including anaphylaxis, have been reported after first or subsequent doses; some have been fatal. Discontinue if hypersensitivity or rash occurs. Telavancin is a semisynthetic derivative of vancomycin; cross-reactivity rates are unknown. Use with caution in patients with known vancomycin hypersensitivity.

- Cardiac conduction alteration: May prolong QTc interval; avoid use in patients with congenital long QT syndrome, known QTc prolongation, uncompensated heart failure, or severe left ventricular hypertrophy (were excluded from studies); use with caution in patients with concurrent administration of other medications known to prolong the QT interval. Clinical studies indicate mean maximal QTc prolongation of 12 to 15 msec at the end of 10 mg/kg infusion.

- Infusion reactions: Rapid IV administration may result in flushing, rash, urticaria, and/or pruritus; slowing or stopping the infusion may alleviate these symptoms.

- Nephrotoxicity: [U.S. Boxed Warning]: New onset or worsening renal impairment has occurred. Monitor renal function prior to, during (at least every 48 to 72 hours; more frequently if indicated), and following therapy in all patients. Usual risk factors include concomitant nephrotoxic medications or baseline comorbidities associated with decreased renal function (eg baseline renal dysfunction, diabetes, hypertension, or heart failure). Contains solubilizer cyclodextrin (hydroxypropyl-beta-cyclodextrin) which may accumulate in patients with renal dysfunction, although the clinical significance of this finding is uncertain (Luke, 2010).

- Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.

Disease-related concerns:

- Renal impairment: [U.S. Boxed Warning]: In clinical studies, patients with pre-existing moderate-to-severe renal impairment (CrCl ≤50 mL/minute) treated for hospital-acquired/ventilator-associated bacterial pneumonia (HABP/VABP) had increased (all cause) mortality versus vancomycin. Use in HABP/VABP only when benefit outweighs risk. In patients with complicated skin and skin structure infections, efficacy may be reduced in patients with a baseline CrCl ≤50 mL/minute.

Concurrent drug therapy issues:

- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

- Elderly: Lower doses are often required secondary to age-related decreases in renal function.

- Pregnancy: [U.S. Boxed Warning]: Based on animal data, adverse developmental outcomes have been observed. Prior to use, women of childbearing potential should have a serum pregnancy test. Use of telavancin is not recommended during pregnancy unless the potential benefit outweighs the risk to the fetus.

Special handling:

- Hazardous agent: Use appropriate precautions for handling and disposal (NIOSH 2014 [group 3]).

Other warnings/precautions:

- Coagulation tests: May interfere with tests used to monitor coagulation (eg, prothrombin time, INR, activated partial thromboplastin time, activated clotting time, coagulation based factor Xa tests) when samples drawn ≤18 hours after drug administration. Blood samples should be collected as close to the next dose of telavancin as possible or a non-phospholipid dependent coagulation test (eg, bleeding time, factor Xa [chromogenic assay], platelet aggregation study, thrombin time) should be used. Consider selecting an alternative anticoagulant not requiring aPTT monitoring; concomitant use of telavancin with IV unfractionated heparin is contraindicated.


Pregnancy Risk Factor

C


Pregnancy Considerations

[US Boxed Warning]: Based on animal data, adverse developmental outcomes have been observed. Prior to use, women of childbearing potential should have a serum pregnancy test. Use of telavancin is not recommended during pregnancy unless the potential benefit to the mother outweighs the possible risk to the fetus. Telavancin crosses the placenta (Nanovskaya, 2012). In women of childbearing potential, effective contraception should be used during therapy.

Healthcare providers are encouraged to enroll women exposed to telavancin during pregnancy in the Vibativ Pregnancy Registry 855-633-8479).


Actions


Pharmacology

Exerts concentration-dependent bactericidal activity; inhibits bacterial cell wall synthesis by blocking polymerization and cross-linking of peptidoglycan by binding to D-Ala-D-Ala portion of cell wall. Unlike vancomycin, additional mechanism involves disruption of membrane potential and changes cell permeability due to presence of lipophilic side chain moiety.


Distribution

Vss: 0.13 L/kg


Excretion

Urine (~76%); feces (<1%)


Half-Life Elimination

6.6-9.6 hours


Protein Binding

~90%; primarily to albumin


Patient and Family Education


Patient Education

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

- Patient may experience proteinuria, change in taste, nausea, vomiting, headache, or diarrhea. Have patient report immediately to prescriber signs of kidney problems (urinary retention, blood in urine, change in amount of urine passed, or weight gain), tachycardia, arrhythmia, severe dizziness, passing out, flushing, rash during infusion, severe injection site irritation, or signs of Clostridium difficile (C. diff)-associated diarrhea (stomach pain or cramps, very loose or watery stools, or bloody stools) (HCAHPS).

- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
