`

`
` FULL PRESCRIBING INFORMATION
`
`
` 1 INDICATIONS AND USAGE
` 1.1 Invasive Aspergillosis
`
`
` VFEND is indicated in adults and pediatric patients (2 years of age and older) for the treatment of invasive
`
`
`
`
`
`
`
`apergillosis (IA). In clinical trials, the majority of isolates recovered were Aspergillus fumigatus. There was a small
`
`
`
`number of cases of culture-proven disease due to species of Aspergillus other than A. fumigatus [see Clinical Studies
`
`(14.1, 14.5) and Microbiology (12.4)].
`
`1.2 Candidemia in Non-neutropenic Patients and Other Deep Tissue Candida Infections
`
`
`
`
`
`
`VFEND is indicated in adults and pediatric patients (2 years of age and older) for the treatment of candidemia in
`
`
`
`non-neutropenic patients and the following Candida infections: disseminated infections in skin and infections in
`
`
`
`
`abdomen, kidney, bladder wall, and wounds [see Clinical Studies (14.2, 14.5) and Microbiology (12.4)].
`1.3 Esophageal Candidiasis
`
`
`
`
`
`
`
`VFEND is indicated in adults and pediatric patients (2 years of age and older) for the treatment of esophageal
`
`
`
`candidiasis (EC) in adults and pediatric patients 2 years of age and older [see Clinical Studies (14.3, 14.5) and
`
`Microbiology (12.4)].
`
`1.4 Scedosporiosis and Fusariosis
`
`
`
`
`
`
`
`VFEND is indicated for the treatment of serious fungal infections caused by Scedosporium apiospermum (asexual
`
`
`
`
`form of Pseudallescheria boydii) and Fusarium spp. including Fusarium solani, in adults and pediatric patients (2
`
`years of age and older) intolerant of, or refractory to, other therapy [see Clinical Studies (14.4) and Microbiology
`
`
`(12.4)].
`
`
`1.5 Usage
`
`
`
`Specimens for fungal culture and other relevant laboratory studies (including histopathology) should be obtained
`
`prior to therapy to isolate and identify causative organism(s). Therapy may be instituted before the results of the
`
`
`cultures and other laboratory studies are known. However, once these results become available, antifungal therapy
`
`should be adjusted accordingly.
`
`
`2 DOSAGE AND ADMINISTRATION
`
`
`Important Administration Instructions for Use in All Patients
`2.1
`
`Administer VFEND Tablets or Oral Suspension at least one hour before or after a meal.
`VFEND I.V. for Injection requires reconstitution to 10 mg/mL and subsequent dilution to 5 mg/mL or less prior to
`
`
`
`administration as an infusion, at a maximum rate of 3 mg/kg per hour over 1 to 2 hours.
`
`
`Administer diluted VFEND I.V. by intravenous infusion over 1 to 2 hours only. Do not administer as an IV
`bolus injection.
`
`
`
`2.2 Use of VFEND I.V. With Other Parenteral Drug Products
`
`Blood products and concentrated electrolytes
`
`
`VFEND I.V. must not be infused concomitantly with any blood product or short-term infusion of
`concentrated electrolytes, even if the two infusions are running in separate intravenous lines (or cannulas).
`
`
`
`
`Electrolyte disturbances such as hypokalemia, hypomagnesemia and hypocalcemia should be corrected prior to
`
`
`initiation of and during VFEND therapy [see Warnings and Precautions (5.9)].
`
`
`
`Intravenous solutions containing (non-concentrated) electrolytes
`
`
`VFEND I.V. can be infused at the same time as other intravenous solutions containing (non-concentrated)
`
`
`electrolytes, but must be infused through a separate line.
`
`Total parenteral nutrition (TPN)
`
`VFEND I.V. can be infused at the same time as total parenteral nutrition, but must be infused in a separate line. If
`
`
`infused through a multiple-lumen catheter, TPN needs to be administered using a different port from the one used
`
`for VFEND I.V.

`

`

` 2.3 Recommended Dosing Regimen in Adults
`
`
`
`
` Invasive aspergillosis and serious fungal infections due to Fusarium spp. and Scedosporium apiospermum
`
`
`
`See Table 1. Therapy must be initiated with the specified loading dose regimen of intravenous VFEND on Day 1
`
`
`
`
`followed by the recommended maintenance dose (RMD) regimen. Intravenous treatment should be continued for at
`
`
`
`least 7 days. Once the patient has clinically improved and can tolerate medication given by mouth, the oral tablet
`
`
`
`form or oral suspension form of VFEND may be utilized. The recommended oral maintenance dose of 200 mg
`
`
`
`
`
`achieves a voriconazole exposure similar to 3 mg/kg intravenously; a 300 mg oral dose achieves an exposure similar
`
`to 4 mg/kg intravenously. Switching between the intravenous and oral formulations is appropriate because of the
`
`
`high bioavailability of the oral formulation in adults [see Clinical Pharmacology (12)].
`
`
`Candidemia in non-neutropenic patients and other deep tissue Candida infections
`
`
`
`
`See Table 1. Patients should be treated for at least 14 days following resolution of symptoms or following last
`
`
`
`positive culture, whichever is longer.
`
`Esophageal Candidiasis
`
`
`
`See Table 1. Patients should be treated for a minimum of 14 days and for at least 7 days following resolution of
`
`symptoms.

`
`
`
`b In healthy volunteer studies, the 200 mg oral every 12 hours dose provided an exposure (AUCτ) similar to a 3 mg/kg intravenous infusion
`
`
`
`

`
`
`
`
`
`every 12 hours dose; the 300 mg oral every 12 hours dose provided an exposure (AUCτ) similar to a 4 mg/kg intravenous infusion every 12
`
`
`hours dose (12).
`
`
`
`
`c Adult patients who weigh less than 40 kg should receive half of the oral maintenance dose.
` d In a clinical study of IA, the median duration of intravenous VFEND therapy was 10 days (range 2 to 85 days). The median duration of oral
`
`
`
`
`
`
` VFEND therapy was 76 days (range 2 to 232 days) (14.1).
`
`
`
`
`
`
`
` In clinical trials, patients with candidemia received 3 mg/kg intravenous infusion every 12 hours as primary therapy, while patients with other
`
`
` deep tissue Candida infections received 4 mg/kg every 12 hours as salvage therapy. Appropriate dose should be based on the severity and
`
`
`
`
`
`
`
` nature of the infection.
`
`
`
` f Not evaluated in patients with EC.
`
`
` Method for Adjusting the Dosing Regimen in Adults
`
`
`
`If patient’s response is inadequate, the oral maintenance dose may be increased from 200 mg every 12 hours (similar
`
`
`
`to 3 mg/kg intravenously every 12 hours) to 300 mg every 12 hours (similar to 4 mg/kg intravenously every 12
`
`
`hours). For adult patients weighing less than 40 kg, the oral maintenance dose may be increased from 100 mg every
`
`12 hours to 150 mg every 12 hours. If patient is unable to tolerate 300 mg orally every 12 hours, reduce the oral
`
`
`
`maintenance dose by 50 mg steps to a minimum of 200 mg every 12 hours (or to 100 mg every 12 hours for adult
`
`
`patients weighing less than 40 kg).
`
`
`If patient is unable to tolerate 4 mg/kg intravenously every 12 hours, reduce the intravenous maintenance dose to
`
`
`3 mg/kg every 12 hours.

`
`2.4 Recommended Dosing Regimen in Pediatric Patients
`
`
`
`
`
`The recommended dosing regimen for pediatric patients 2 to less than 12 years of age and 12 to 14 years of age with
`
`
`
`body weight less than 50 kg is shown in Table 2. For pediatric patients 12 to 14 years of age with a body weight
`
`
`
`
`greater than or equal to 50 kg and those 15 years of age and above regardless of body weight, administer the adult
`
`
`dosing regimen of VFEND [see Dosage and Administration (2.3)].

`
`
`
` ^ Based on a population pharmacokinetic analysis in 112 immunocompromised pediatric patients aged 2 to less than12 years of age and 26
`
`
`
`
`
`immunocompromised pediatric patients aged 12 to less than 17 years of age.
`
`
`
`
`
`
`* In the Phase 3 clinical trials, patients with IA received intravenous (IV) treatment for at least 6 weeks and up to a maximum of 12 weeks.
`
`
`
`Patients received IV treatment for at least the first 7 days of therapy and then could be switched to oral VFEND therapy.
`
`
`
`† Study treatment for primary or salvage invasive candidiasis and candidemia (ICC) or EC consisted of intravenous VFEND, with an option to
`
`
`
`
`
`
`switch to oral therapy after at least 5 days of IV therapy, based on subjects meeting switch criteria. For subjects with primary or salvage ICC,
`
`
`
`
`
`VFEND was administered for at least 14 days after the last positive culture. A maximum of 42 days of treatment was permitted. Patients with
`
`
`primary or salvage EC were treated for at least 7 days after the resolution of clinical signs and symptoms. A maximum of 42 days of treatment
`
`was permitted.
` Initiate therapy with an intravenous infusion regimen. Consider an oral regimen only after there is a significant
`
`
`
`
`clinical improvement. Note that an 8 mg/kg intravenous dose will provide voriconazole exposure approximately
`
`
`
`2-fold higher than a 9 mg/kg oral dose.
`
`The oral dose recommendation for children is based on studies in which VFEND was administered as the powder
`
`
`
`
`for oral suspension formulation. Bioequivalence between the VFEND powder for oral suspension and VFEND
`
`
`tablets has not been investigated in a pediatric population.
`
`
`Oral bioavailability may be limited in pediatric patients 2 to 12 years with malabsorption and very low body weight
`
`
`
`
`
`for age. In that case, intravenous VFEND administration is recommended.
`
`Method for Adjusting the Dosing Regimen in Pediatric Patients
`
`
`Pediatric Patients 2 to less than 12 years of age and 12 to 14 years of age with body weight less than 50 kg
`
`
`If patient response is inadequate and the patient is able to tolerate the initial intravenous maintenance dose, the
`
`
`maintenance dose may be increased by 1 mg/kg steps. If patient response is inadequate and the patient is able to
`
`
`tolerate the oral maintenance dose, the dose may be increased by 1 mg/kg steps or 50 mg steps to a maximum of 350
`
`
`
`
`
`mg every 12 hours. If patients are unable to tolerate the initial intravenous maintenance dose, reduce the dose by 1
`
`
`
`mg/kg steps. If patients are unable to tolerate the oral maintenance dose, reduce the dose by 1 mg/kg or 50 mg steps.
`
`
`Pediatric patients 12 to 14 years of age weighing greater than or equal to 50 kg and 15 years of age and older
`
`regardless of body weight:
`
`Use the optimal method for titrating dosage recommended for adults [see Dosage and Administration (2.3)].
`
`
`
`2.5 Dosage Modifications in Patients With Hepatic Impairment
`
`
`
`Adults
`
`The maintenance dose of VFEND should be reduced in adult patients with mild to moderate hepatic impairment,
`
`
`
`
`Child-Pugh Class A and B. There are no PK data to allow for dosage adjustment recommendations in patients with
`
`
`
`
`
`
`severe hepatic impairment (Child-Pugh Class C).
`
`Duration of therapy should be based on the severity of the patient’s underlying disease, recovery from
`
`
`
`immunosuppression, and clinical response.
`
`Adult patients with baseline liver function tests (ALT, AST) of up to 5 times the upper limit of normal (ULN) were
`
`included in the clinical program. Dose adjustments are not necessary for adult patients with this degree of abnormal
`
`
`
`liver function, but continued monitoring of liver function tests for further elevations is recommended [see Warnings
`
`
`
`
`
`and Precautions (5.1)].
`
`It is recommended that the recommended VFEND loading dose regimens be used, but that the maintenance dose be
`halved in adult patients with mild to moderate hepatic cirrhosis (Child-Pugh Class A and B) [see Clinical
`
`
`
`
`Pharmacology (12.3)].
`
`
`Reference ID: 4426509
`
`
`
` 5
`
`

`

`
`
`
`
`
` VFEND has not been studied in adult patients with severe hepatic cirrhosis (Child-Pugh Class C) or in patients with
`
` chronic hepatitis B or chronic hepatitis C disease. VFEND has been associated with elevations in liver function tests
`
`
`
` and with clinical signs of liver damage, such as jaundice. VFEND should only be used in patients with severe
`
`
`
` hepatic impairment if the benefit outweighs the potential risk. Patients with hepatic impairment must be carefully
`
`
` monitored for drug toxicity.
`
` Pediatric Patients
`Dosage adjustment of VFEND in pediatric patients with hepatic impairment has not been established [see Use in
`
`
`
`
`
`Specific Populations (8.4)].
`
`2.6 Dosage Modifications in Patients With Renal Impairment
`
`
`
`Adult Patients
`
`The pharmacokinetics of orally administered VFEND are not significantly affected by renal impairment. Therefore,
`
`no adjustment is necessary for oral dosing in patients with mild to severe renal impairment [see Clinical
`
`
`
`
`
`
`Pharmacology (12.3)].
`
`In patients with moderate or severe renal impairment (creatinine clearance <50 mL/min) who are receiving an
`
`
`
`
`
`intravenous infusion of VFEND, accumulation of the intravenous vehicle, SBECD, occurs. Oral voriconazole should
`
`
`be administered to these patients, unless an assessment of the benefit/risk to the patient justifies the use of
`
`
`
`intravenous VFEND. Serum creatinine levels should be closely monitored in these patients, and, if increases occur,
`
`
`consideration should be given to changing to oral VFEND therapy [see Warnings and Precautions (5.7)].
`
`
`
`Voriconazole is hemodialyzed with clearance of 121 mL/min. The intravenous vehicle, SBECD, is hemodialyzed
`
`
`
`with clearance of 55 mL/min. A 4-hour hemodialysis session does not remove a sufficient amount of voriconazole to
`
`
`
`
`warrant dose adjustment.
`
`Pediatric Patients
`
`Dosage adjustment of VFEND in pediatric patients with renal impairment has not been established [see Use in
`
`
`
`
`Specific Populations (8.4)].
`
`2.7 Dosage Adjustment When Co-Administered With Phenytoin or Efavirenz
`
`
`
`The maintenance dose of voriconazole should be increased when co-administered with phenytoin or efavirenz. Use
`
`
`
`the optimal method for titrating dosage [see Drug Interactions (7) and Dosage and Administration (2.3)].
`
`
`
`2.8 Preparation and Intravenous Administration of VFEND for Injection
`
`
`
`
`Reconstitution
`
`The powder is reconstituted with 19 mL of Water For Injection to obtain an extractable volume of 20 mL of clear
`
`
`
`
`
`concentrate containing 10 mg/mL of voriconazole. It is recommended that a standard 20 mL (non-automated)
`
`
`syringe be used to ensure that the exact amount (19.0 mL) of Water for Injection is dispensed. Discard the vial if a
`
`
`vacuum does not pull the diluent into the vial. Shake the vial until all the powder is dissolved.
`Dilution
`
`VFEND must be infused over 1 to 3 hours, at a concentration of 5 mg/mL or less. Therefore, the required volume of
`
`
`
`the 10 mg/mL VFEND concentrate should be further diluted as follows (appropriate diluents listed below):
`
`
`1. Calculate the volume of 10 mg/mL VFEND concentrate required based on the patient’s weight (see Table 3).
`
`
`
`
`
`2.
`In order to allow the required volume of VFEND concentrate to be added, withdraw and discard at least an
`
`
`equal volume of diluent from the infusion bag or bottle to be used. The volume of diluent remaining in the bag
`
`or bottle should be such that when the 10 mg/mL VFEND concentrate is added, the final concentration is not
`
`
`
`
`less than 0.5 mg/mL nor greater than 5 mg/mL.
`
`
`
`
`3. Using a suitable size syringe and aseptic technique, withdraw the required volume of VFEND concentrate from
`
`
`
`the appropriate number of vials and add to the infusion bag or bottle. Discard Partially Used Vials.
`
`
`The final VFEND solution must be infused over 1 to 3 hours at a maximum rate of 3 mg/kg per hour.

`
`
`VFEND I.V. for Injection is a single-dose unpreserved sterile lyophile. Therefore, from a microbiological point of
`
`view, once reconstituted, the product should be used immediately. If not used immediately, in-use storage times and
`
`
`conditions prior to use are the responsibility of the user and should not be longer than 24 hours at 2°C to 8°C (36°F
`
`to 46°F). This medicinal product is for single use only and any unused solution should be discarded. Only clear
`
`
`
`
`
`
`solutions without particles should be used.
`
`
`The reconstituted solution can be diluted with:
`
`
`0.9% Sodium Chloride USP
`
`Lactated Ringers USP

`
`The compatibility of VFEND I.V. with diluents other than those described above is unknown (see Incompatibilities
`
`
`
`below).
`
`Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration,
`
`
`
`whenever solution and container permit.
`
`Incompatibilities
`
`
`
`
`
`VFEND I.V. must not be diluted with 4.2% Sodium Bicarbonate Infusion. The mildly alkaline nature of this diluent
`
`
`
`
`caused slight degradation of VFEND after 24 hours storage at room temperature. Although refrigerated storage is
`
`
`
`
`recommended following reconstitution, use of this diluent is not recommended as a precautionary measure.
`
`
`
`Compatibility with other concentrations is unknown.
