Pharmacology
Isavuconazonium sulfate is a prodrug that is rapidly hydrolyzed in the blood to active isavuconazole. Isavuconazole inhibits the synthesis of ergosterol, a key component of the fungal cell membrane, through the inhibition of cytochrome P-450 dependent enzyme lanosterol 14-alpha-demethylase. This enzyme is responsible for the conversion of lanosterol to ergosterol. An accumulation of methylated sterol precursors and a depletion of ergosterol within the fungal cell membrane weakens the membrane structure and function.
Distribution
Vss: IV: ~450 L
Metabolism
Metabolism: Isavuconazonium sulfate (prodrug) is rapidly hydrolyzed in the blood by esterases to active isavuconazole and an inactive cleavage product. Isavuconazole is metabolized by CYP3A4, CYP 3A5 and UGT.
Excretion
Urine (<1% as unchanged isavuconazole); feces (33% as unchanged isavuconazole) (Townsend 2018).
Time to Peak
Oral: 2 to 3 hours
Half-Life Elimination
IV: 130 hours
Protein Binding
>99% (primarily to albumin)
Special Populations: Hepatic Function Impairment
Patients with mild and moderate hepatic impairment had 40% and 48% lower isavuconazole Cl values, respectively, compared with healthy subjects.
Special Populations: Race
Chinese subjects were found to have on average a 40% lower clearance compared with Western subjects (1.6 L/hour for Chinese subjects compared with 2.6 L/hour for Western subjects) and therefore approximately 50% higher AUC than Western subjects.
Use: Labeled Indications
Aspergillosis: Treatment of invasive aspergillosis in adults
Mucormycosis: Treatment of invasive mucormycosis in adults
Off Label Uses
Candidiasis, esophageal in patients with HIV
Based on the US Department of Health and Human Services (HHS) Guidelines for prevention and treatment of opportunistic infections in adults and adolescents with HIV, oral isavuconazole is an effective and recommended treatment option for esophageal candidiasis in patients with HIV (alternative agent) [HHS [OI adult 2020]].
Contraindications

Reconstitution
Reconstitute 1 vial of isavuconazonium with 5 mL SWFI. Shake gently to dissolve. The reconstituted solution may be stored below 25°C for a maximum of 1 hour prior to preparation of the admixed solution. Remove 5 mL of the reconstituted solution from the vial and add it to an infusion bag containing 250 mL (approximately isavuconazonium sulfate 1.5 mg/mL) of NS or D5W. The diluted solution may show visible translucent to white particulates of isavuconazole (will be removed by in-line filtration). Use gentle mixing or roll bag to minimize the formation of particulates. Avoid unnecessary vibration or vigorous shaking of the solution. Do not use a pneumatic transport system. Apply in-line filter with a microporous membrane pore size of 0.2 to 1.2 micron and in-line filter reminder sticker to the infusion bag. The IV administration should be completed within 6 hours at 20°C to 25°C (68°F to 77°F). If this is not possible, immediately refrigerate (2°C to 8°C [36°F to 46°F]) the admixed solution and complete the infusion within 24 hours.
Administration
IV: Infuse over a minimum of 1 hour; must be administered via an infusion set with an in-line filter (pore size 0.2 to 1.2 micron). Flush line with NS or D5W before and after infusion. Do not administer as an IV bolus injection.
Oral: Administer with or without food. The manufacturer recommends to swallow capsules whole; do not chew, crush, dissolve, or open. Administration of isavuconazole by opening capsules and mixing contents with saline or tube feed formulations for administration via enteral feeding tubes has resulted in comparable isavuconazole concentrations to IV administration and intact capsule formulations. If capsules are opened, consider assessing serum concentrations to ensure absorption (Adamsick 2019; McCreary 2020).
Storage
Capsules: Store at 20°C to 25°C (68°F to 77°F) in the original packaging to protect from moisture; excursions are permitted between 15°C and 30°C (59°F and 86°F).
IV: Store intact vials at 2°C to 8°C (36°F to 46°F). Following reconstitution of the vial with SWFI, use the solution immediately, or stored below 25°C for a maximum of 1 hour prior to preparation of the admixed solution in NS or D5W. The admixed infusion solution should be kept for not more than 6 hours at (20°C to 25°C [68°F to 77°F]) or 24 hours at 2°C to 8°C (36°F to 46°F) prior to use. Do not freeze.

Warnings/Precautions
Concerns related to adverse effects:
• Hepatic effects: Severe reactions (hepatic failure [including fatalities], hepatitis, and cholestasis) have been reported in patients with serious underlying medical conditions (eg, hematologic malignancy). Other reactions (elevations in AST, ALT, alkaline phosphatase and total bilirubin) have also been reported; these elevations are generally reversible and do not require discontinuation of therapy. Monitor liver function tests at baseline and periodically during therapy. If abnormal liver function tests develop, monitor closely for development of severe hepatic reactions. Discontinue therapy if clinical signs and symptoms of liver disease develop.
• Hypersensitivity: Serious hypersensitivity (eg, anaphylaxis) and severe skin reactions (eg, Stevens-Johnson syndrome) have been reported with other azole antifungal agents. Discontinue if a severe skin reaction occurs. There is no information regarding cross-sensitivity between isavuconazonium sulfate and other azoles. Use with caution in patients with hypersensitivity reactions to other azoles.
Disease-related concerns:
• Hepatic impairment: Use with caution and monitor for adverse effects in patients with severe hepatic impairment (Child-Pugh class C).
Dosage form specific issues:
• Drug particulates: Following dilution for IV infusion, may form precipitate from the insoluble isavuconazole. Use an infusion set with an in-line filter (pore size 0.2 to 1.2 micron) for IV administration.
• Infusion-related reactions: Infusion reactions (eg, hypotension, dizziness, chills, dyspnea, paresthesia and hypoesthesia) have been reported during IV administration. Discontinue the infusion if these reactions occur.
Monitoring Parameters
Hypersensitivity reactions with initial doses, LFTs (eg AST, ALT, alkaline phosphatase, total bilirubin) at baseline and periodically during therapy. Infusion-related reactions (eg hypotension, dyspnea, chills, dizziness, paresthesias, hypoesthesia) during IV infusion.
Routine therapeutic drug monitoring is not recommended; consider assessing serum drug concentrations if there is concern for toxicity, therapeutic failure, or possibility of impaired drug absorption (Adamsick 2019; Andes 2018; McCreary 2020; Schmitt-Hoffman 2009).
Reproductive Considerations
Evaluate pregnancy status prior to use in females of reproductive potential. Females of reproductive potential should use effective contraception during therapy and for 28 days after the last isavuconazonium sulfate dose.
Pregnancy Considerations
Based on data from animal reproduction studies, in utero exposure to isavuconazonium sulfate may cause fetal harm.
Use of alternative antifungals is recommended in pregnant women (HHS [OI 2019]).
