`
`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
`2.1
`Important Administration Instructions for Use in All Patients
`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)].
`3
`
`Reference ID: 4383042
`
`
`
`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.

`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.
`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
`d
`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)].

`
`
`
`* 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)].
`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)].
`
`5
`
`Reference ID: 4383042
`
`
`
`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 2C to 8C (36F to 46F). 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
`5% Dextrose and Lactated Ringers USP
`5% Dextrose and 0.45% Sodium Chloride USP
`5% Dextrose USP
`5% Dextrose and 20 mEq Potassium Chloride USP
`0.45% Sodium Chloride USP
`5% Dextrose and 0.9% Sodium Chloride 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.
`2.9 Preparation and Administration of VFEND Oral Suspension
`Reconstitution
`Tap the bottle to release the powder. Add 46 mL of water to the bottle. Shake the closed bottle vigorously for about 1 minute. Remove
`child-resistant cap and push bottle adaptor into the neck of the bottle. Replace the cap. Write the date of expiration of the reconstituted
`suspension on the bottle label (the shelf-life of the reconstituted suspension is 14 days at controlled room temperature 15°C to 30°C
`[59°F to 86°F]).
`Instructions for use
`Shake the closed bottle of reconstituted suspension for approximately 10 seconds before each use. The reconstituted oral suspension
`should only be administered using the oral dispenser supplied with each pack.
`Incompatibilities
`VFEND for Oral Suspension and the 40 mg/mL reconstituted oral suspension should not be mixed with any other medication or
`additional flavoring agent. It is not intended that the suspension be further diluted with water or other vehicles.
`3 DOSAGE FORMS AND STRENGTHS
`Powder for Solution for Injection
`VFEND I.V. for Injection is supplied in a single-dose vial as a sterile lyophilized powder equivalent to 200 mg voriconazole and 3,200
`mg sulfobutyl ether beta-cyclodextrin sodium (SBECD).
`Tablets
`VFEND 50 mg tablets; white, film-coated, round, debossed with “Pfizer” on one side and “VOR50” on the reverse.
`VFEND 200 mg tablets; white, film-coated, capsule shaped, debossed with “Pfizer” on one side and “VOR200” on the reverse.
`Powder for Oral Suspension
`VFEND for Oral Suspension is supplied in 100 mL high density polyethylene (HDPE) bottles. Each bottle contains 45 grams of
`powder for oral suspension. Following reconstitution, the volume of the suspension is 75 mL, providing a usable volume of 70 mL
`(40 mg voriconazole/mL). A 5 mL oral dispenser and a press-in bottle adaptor are also provided.
`4 CONTRAINDICATIONS
` VFEND is contraindicated in patients with known hypersensitivity to voriconazole or its excipients. There is no information
`regarding cross-sensitivity between VFEND (voriconazole) and other azole antifungal agents. Caution should be used when
`prescribing VFEND to patients with hypersensitivity to other azoles.

`
`Coadministration of cisapride, pimozide or quinidine with VFEND is contraindicated because increased plasma
`concentrations of these drugs can lead to QT prolongation and rare occurrences of torsade de pointes [see Drug Interactions
`(7) and Clinical Pharmacology (12.3)].
`Coadministration of VFEND with sirolimus is contraindicated because VFEND significantly increases sirolimus
`concentrations [see Drug Interactions (7) and Clinical Pharmacology (12.3)].
`Coadministration of VFEND with rifampin, carbamazepine and long-acting barbiturates is contraindicated because these
`drugs are likely to decrease plasma voriconazole concentrations significantly [see Drug Interactions (7) and Clinical
`Pharmacology (12.3)].
`Coadministration of standard doses of voriconazole with efavirenz doses of 400 mg every 24 hours or higher is
`contraindicated, because efavirenz significantly decreases plasma voriconazole concentrations in healthy subjects at these
`doses. Voriconazole also significantly increases efavirenz plasma concentrations [see Drug Interactions (7) and Clinical
`Pharmacology (12.3)].
`Coadministration of VFEND with high-dose ritonavir (400 mg every 12 hours) is contraindicated because ritonavir (400 mg
`every 12 hours) significantly decreases plasma voriconazole concentrations. Coadministration of voriconazole and low-dose
`ritonavir (100 mg every 12 hours) should be avoided, unless an assessment of the benefit/risk to the patient justifies the use of
`voriconazole [see Drug Interactions (7) and Clinical Pharmacology (12.3)].
`Coadministration of VFEND with rifabutin is contraindicated since VFEND significantly increases rifabutin plasma
`concentrations and rifabutin also significantly decreases voriconazole plasma concentrations [see Drug Interactions (7) and
`Clinical Pharmacology (12.3)].
`Coadministration of VFEND with ergot alkaloids (ergotamine and dihydroergotamine) is contraindicated because VFEND
`may increase the plasma concentration of ergot alkaloids, which may lead to ergotism [see Drug Interactions (7) and Clinical
`Pharmacology (12.3)].
