`
`
`
` FULL PRESCRIBING INFORMATION
`
`
` 1 INDICATIONS AND USAGE
` VFEND is indicated for use in patients 12 years of age and older in the treatment of the following fungal infections:
`
`
` 1.1 Invasive Aspergillosis
`
`
` 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) and
`
`
`
`
`
`
` Clinical Pharmacology (12.4)].
` 1.2 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) and Clinical Pharmacology (12.4)]
`
` 1.3 Esophageal Candidiasis
`
`
`
`
` [see Clinical Studies (14.3) and Clinical Pharmacology (12.4)]
`
`
`
` 1.4 Serious Fungal Infections Caused by Scedosporium apiospermum (Asexual Form of Pseudallescheria
`
`
`
`
`
`
`
`
`
` boydii) and Fusarium spp. Including Fusarium solani, in Patients Intolerant of, or Refractory to, Other
`
`
`
`
`
`
`
`
` Therapy
` [see Clinical Studies (14.4) and Clinical Pharmacology (12.4)]
`
`
`
`
`
`
` 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
` Instructions for Use in All Patients
`
` VFEND Tablets or Oral Suspension should be taken 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.
` 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 (5.8)].
`
`
`
`
`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 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 IV; a 300 mg oral dose achieves an exposure similar to 4
`
` 3
`
`
`
`Reference ID: 4112379
`
`
`
` mg/kg IV. 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 q12h dose provided an exposure (AUCτ) similar to a 3 mg/kg IV q12h dose; the 300 mg oral
`
`
`
`
`
`
`
`
`q12h dose provided an exposure (AUCτ) similar to a 4 mg/kg IV q12h dose [see Clinical Pharmacology (12)].
`
`
`
`
`
`
`c Adult patients who weigh less than 40 kg should receive half of the oral maintenance dose.
`
`
`
`
` d In a clinical study of invasive aspergillosis, the median duration of IV VFEND therapy was 10 days (range 2-85 days). The median duration of
`
`
`
` oral VFEND therapy was 76 days (range 2-232 days) [see Clinical Studies (14.1)].
`
`
`
` In clinical trials, patients with candidemia received 3 mg/kg IV q12h as primary therapy, while patients with other deep tissue Candida
`
`
`
`
`
`
` infections received 4 mg/kg q12h as salvage therapy. Appropriate dose should be based on the severity and nature of the infection.
`
`
`
`
`
`
`
` f Not evaluated in patients with esophageal candidiasis.
`
`
`2.4 Dosage Adjustment
`
`
`
`
`
`If patient response is inadequate, the oral maintenance dose may be increased from 200 mg every 12 hours (similar
`
`
`
`
`to 3 mg/kg IV q12h) to 300 mg every 12 hours (similar to 4 mg/kg IV q12h). 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 IV q12h, reduce the intravenous maintenance dose to 3 mg/kg q12h.
`The maintenance dose of voriconazole should be increased when co-administered with phenytoin or efavirenz [see
`
`Drug Interactions (7)].
`
`
`
`
`The maintenance dose of voriconazole should be reduced in patients with mild to moderate hepatic impairment,
`
`Child-Pugh Class A and B [see Dosage and Administration (2.7)]. 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.

`
`
`
`
`
` 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 1-2 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 2).
`
`
`
`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 1-2 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° to 8°C (36° 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 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.
`
`
`
`2.6 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 15-30°C [59-86°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.
`
`
`
`2.7 Use in Patients With Hepatic Impairment
`
`
`
`In the clinical program, patients were included who had baseline liver function tests (ALT, AST) up to 5 times the
`
`
`
`
`upper limit of normal. No dose adjustment is necessary in patients with this degree of abnormal liver function, but
`
`
`continued monitoring of liver function tests for further elevations is recommended [see Warnings and Precautions
`
`
`
`(5.9)].
`
`
`It is recommended that the standard loading dose regimens be used but that the maintenance dose be halved in
`patients with mild to moderate hepatic cirrhosis (Child-Pugh Class A and B) [see Clinical Pharmacology (12.3)].
`
`
`
`
`
`
`
`
`
`
`
`VFEND has not been studied in 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 clinical signs of liver damage, such as jaundice, and 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.
`
`
`
`
`2.8 Use in Patients With Renal Impairment
`
`
`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), 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 voriconazole. Serum creatinine levels
`
`
`
`
`should be closely monitored in these patients, and, if increases occur, consideration should be given to changing to
`
`
`
`oral voriconazole therapy [see Warnings and Precautions (5.10)].

`
`
`
`
`
`
`
` 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.

`
`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 terfenadine, astemizole, 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 q24h 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 q12h) is contraindicated because ritonavir
`
`
`
`
`(400 mg q12h) significantly decreases plasma voriconazole concentrations. Coadministration of
`
`voriconazole and low-dose ritonavir (100 mg q12h) 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)].

`
`
`
`
`

`
` • Coadministration of VFEND with St. John’s Wort is contraindicated because this herbal supplement may
`
` decrease voriconazole plasma concentration [see Drug Interactions (7) and Clinical Pharmacology (12.3)].
`
`
`
`
`
`
` 5 WARNINGS AND PRECAUTIONS
` 5.1 Drug Interactions
`
`
`
`
` See Table 7 for a listing of drugs that may significantly alter voriconazole concentrations. Also, see Table 8 for a
`
` listing of drugs that may interact with voriconazole resulting in altered pharmacokinetics or pharmacodynamics of
`
` the other drug [see Contraindications (4) and Drug Interactions (7)].
`
`
`
`
` 5.2 Hepatic Toxicity
`
` In clinical trials, there have been uncommon cases of serious hepatic reactions during treatment with VFEND
` (including clinical hepatitis, cholestasis and fulminant hepatic failure, including fatalities). Instances of hepatic
`
`
`
` reactions were noted to occur primarily in patients with serious underlying medical conditions (predominantly
`
`
`
`
` hematological malignancy). Hepatic reactions, including hepatitis and jaundice, have occurred among patients with
`
`
`
`no other identifiable risk factors. Liver dysfunction has usually been reversible on discontinuation of therapy [see
`
`
` Warnings and Precautions (5.9) and Adverse Reactions (6.3)].
`
`
`
` Measure serum transaminase levels and bilirubin at the initiation of VFEND therapy and monitor at least weekly for
` the first month of treatment. Monitoring frequency can be reduced to monthly during continued use if no clinically
`
`
`
`
`
`
`
` significant changes are noted. If liver function tests become markedly elevated compared to baseline, VFEND
`
` should be discontinued unless the medical judgment of the benefit-risk of the treatment for the patient justifies
`
`
` continued use [see Warnings and Precautions (5.9), Dosage and Administration (2.4, 2.7), and Adverse Reactions
`
`
`
`
` (6.3)].
`
` 5.3 Visual Disturbances
`
` The effect of VFEND on visual function is not known if treatment continues beyond 28 days. There have been
`
`
`
` post-marketing reports of prolonged visual adverse events, including optic neuritis and papilledema. If treatment
` continues beyond 28 days, visual function including visual acuity, visual field and color perception should be
`
`
`
`
`
`
` monitored [see Adverse Reactions (6.2)].
`
`
`
` 5.4 Embryo-Fetal Toxicity
`
`
`
`
`
`
` Voriconazole can cause fetal harm when administered to a pregnant woman.
` In animals, voriconazole administration was associated with teratogenicity, embryotoxicity, increased gestational
`
`
`
`
`
` length, dystocia and embryomortality [see Use in Specific Populations (8.1)].
` If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, inform the patient of
`
`
`
` the potential hazard to the fetus.
` 5.5 Galactose Intolerance
`
`
` VFEND tablets contain lactose and should not be given to patients with rare hereditary problems of galactose
`
`
`
` intolerance, Lapp lactase deficiency or glucose-galactose malabsorption.
` 5.6 Arrhythmias and QT Prolongation
`
`
`
`
`
` Some azoles, including voriconazole, have been associated with prolongation of the QT interval on the
` electrocardiogram. During clinical development and post-marketing surveillance, there have been rare cases of
`
`
`
` arrhythmias, (including ventricular arrhythmias such as torsade de pointes), cardiac arrests and sudden deaths in
`
`
` patients taking voriconazole. These cases usually involved seriously ill patients with multiple confounding risk
`
`
`
`
`
`
`
` factors, such as history of cardiotoxic chemotherapy, cardiomyopathy, hypokalemia and concomitant medications
` that may have been contributory.
`
`
`
` Voriconazole should be administered with caution to patients with potentially proarrhythmic conditions, such as:
`
` • Congenital or acquired QT-prolongation
`
`
` • Cardiomyopathy, in particular when heart failure is present
`
`
`
`
`• Sinus bradycardia

`
`
`
`
` • Existing symptomatic arrhythmias
`
` • Concomitant medicinal product that is known to prolong QT interval [see Contraindications (4), Drug
`
`
`
` Interactions (7), and Clinical Pharmacology (12.3)]
`
`
`
`
`
`
`
`
`Rigorous attempts to correct potassium, magnesium and calcium should be made before starting and during
`
`
`voriconazole therapy [see Clinical Pharmacology (12.3)].
`
`
`
`
`Infusion Related Reactions
`5.7
`
`
`
`
`During infusion of the intravenous formulation of voriconazole in healthy subjects, anaphylactoid-type reactions,
`
`including flushing, fever, sweating, tachycardia, chest tightness, dyspnea, faintness, nausea, pruritus and rash, have
`
`occurred uncommonly. Symptoms appeared immediately upon initiating the infusion. Consideration should be given
`
`
`to stopping the infusion should these reactions occur.
`
`
`5.8 Laboratory Tests
`Electrolyte disturbances such as hypokalemia, hypomagnesemia and hypocalcemia should be corrected prior to
`
`
`initiation of and during VFEND therapy.
`
`
`
`Patient management should include laboratory evaluation of renal (particularly serum creatinine) and hepatic
`
`
`function (particularly liver function tests and bilirubi
