Clinical
Micafungin is used to treat certain fungal infections that have caused esophagitis ( infection of the throat), spread to the bloodstream, have caused abscesses (collection of pus in body tissue) or caused peritonitis (infection of the lining of the stomach) in adults and children. It is also used to prevent fungal infections in adults and children who have undergone a hematopoietic stem cell transplant (HSCT; procedure in which certain blood cells are removed from the body and then returned to the body). Micafungin is in a class of medications called echinocandins. It works by stopping the bui...

👥 Use in Specific Populations ▾
8.1Pregnancy Risk Summary Based on findings from animal studies, micafungin for injection may cause fetal harm when administered to a pregnant woman (see Data) . There is insufficient human data on the use of micafungin for injection in pregnant women to inform a drug-associated risk of adverse developmental outcomes. In animal reproduction studies, intravenous administration of micafungin sodium to pregnant rabbits during organogenesis at doses four times the maximum recommended human dose resulted in visceral abnormalities and increased abortion (see Data) .
Advise pregnant women of the risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data In an embryo-fetal toxicity study in pregnant rabbits, intravenous administration of micafungin sodium during organogenesis (days 6 to 18 of gestation) resulted in fetal visceral abnormalities and abortion at 32 mg/kg, a dose equivalent to four times the recommended human dose based on body surface area comparisons. Visceral abnormalities included abnormal lobation of the lung, levocardia, retrocaval ureter, anomalous right subclavian artery, and dilatation of the ureter.
8.2Lactation Risk Summary There are no data on the presence of micafungin in human milk, the effects on the breast-fed infant or the effects on milk production. Micafungin was present in the milk of lactating rats following intravenous administration. When a drug is present in animal milk, it is likely that the drug will be present in human milk.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for micafungin for injection, and any potential adverse effects on the breast-fed child from micafungin for injection, or from the underlying maternal condition.
8.4Pediatric Use Pediatric Patients 4 Months of Age and Older The safety and effectiveness of micafungin for injection for the treatment of esophageal candidiasis, candidemia, acute disseminated candidiasis, Candida peritonitis and abscesses, esophageal candidiasis, and for prophylaxis of Candida infections in patients undergoing HSCT have been established in pediatric patients 4 months of age and older. Use of micafungin for injection for these indications and in this age group is supported by evidence from adequate and well-controlled studies in adult and pediatric patients with additional pharmacokinetic and safety data in pediatric patients 4 months of age and older [see Indications and Usage (1), Adverse Reactions (6.1), Clinical Pharmacology (12.3), and Clinical Studies (14)] .
Pediatric Patients Younger than 4 Months of Age Treatment of Candidemia, Acute Disseminated Candidiasis, Candida Peritonitis and Abscesses Without Meningoencephalitis and/or Ocular Dissemination in Pediatric Patients Younger Than 4 Months of Age The safety and effectiveness of micafungin for injection for the treatment of candidemia, acute disseminated candidiasis, Candida peritonitis and abscesses without meningoencephalitis and/or ocular dissemination at a dosage of 4 mg/kg once daily have been established in pediatric patients younger than 4 months of age.

🆘 Overdosage ▾
Micafungin for injection is highly protein bound and, therefore, is not dialyzable. No cases of micafungin for injection overdosage have been reported. Repeated daily doses up to 8 mg/kg (maximum total dose of 896 mg) in adult patients, up to 6 mg/kg in pediatric patients 4 months of age and older, and up to 15 mg/kg in pediatric patients younger than 4 months of age have been administered in clinical trials with no reported dose-limiting toxicity [see Adverse Reactions (6.1) and Use in Specific Populations (8.4)] .
🧬 Clinical Pharmacology ▾
12.1Mechanism of Action Micafungin is a member of the echinocandin class of antifungal agents [see Microbiology (12.4)] .
12.2Pharmacodynamics The pharmacodynamics of micafungin related to hematogenous Candida meningoencephalitis are described in other sections of the prescribing information [see Use in Specific Populations (8.4) and Microbiology (12.4)] .
12.3Pharmacokinetics Adults The pharmacokinetics of micafungin were determined in healthy subjects, hematopoietic stem cell transplant recipients, and patients with esophageal candidiasis up to a maximum daily dose of 8 mg/kg body weight. The relationship of area under the concentration-time curve (AUC) to micafungin dose was linear over the daily dose range of 50 mg to 150 mg and 3 mg/kg to 8 mg/kg body weight. Typically, 85% of the steady-state concentration is achieved after three daily micafungin for injection doses.
Steady-state pharmacokinetic parameters in relevant patient populations after repeated daily administration are presented in Table 7. Table 7.

Pediatric Patients Younger than 4 Months of Age Micafungin pharmacokinetic data in 103 pediatric patients less than 4 months of age were assessed using population pharmacokinetics. Predicted micafungin AUC estimates were dose proportional across the dose regimens and age ranges studied. The body weight-normalized micafungin clearance in pediatric patients less than 4 months of age is higher than the body weight-normalized micafungin clearance in older pediatric patients greater than 4 months of age and adults.
Administration of 4 mg/kg once daily micafungin to pediatric patients less than 4 months of age produces a mean (SD) steady-state AUC of 131 (50) mcg·h/mL, which is comparable to the steady-state AUC in pediatric patients 4 months of age and older administered micafungin 2 mg/kg/day and adults administered 100 mg once daily.

📋 Description ▾
Micafungin for Injection USP is a sterile, lyophilized product for intravenous (IV) infusion that contains Micafungin Sodium USP. Micafungin Sodium USP is a semisynthetic lipopeptide (echinocandin) synthesized by a chemical modification of a fermentation product of Coleophoma empetri F-11899. Micafungin inhibits the synthesis of 1,3-beta-D-glucan, an integral component of the fungal cell wall.
Each single-dose vial contains 50 mg micafungin (equivalent to 50.86 mg Micafungin Sodium USP) or 100 mg micafungin (equivalent to 101.73 mg Micafungin Sodium USP), 200 mg lactose monohydrate, with citric acid and/or sodium hydroxide (used for pH adjustment). Micafungin for Injection USP must be diluted with 0.9% Sodium Chloride Injection, USP, or 5% Dextrose Injection, USP [see Dosage and Administration (2)] . Following reconstitution with 0.9% Sodium Chloride Injection, USP, the resulting pH of the solution is between 5-7.
Micafungin Sodium USP is chemically designated as: Pneumocandin A0,1-[(4 R ,5 R )-4,5-dihydroxy- N 2 -[4-[5-[4-(pentyloxy) phenyl]-3-isoxazolyl]benzoyl]-L-ornithine]-4-[(4 S )4-hydroxy-4-[4-hydroxy-3-(sulfooxy)phenyl]-L-threonine]-, monosodium salt.

🔬 Clinical Studies ▾
14.1Treatment of Candidemia and Other Candida Infections in Adult and Pediatric Patients 4 Months of Age and Older Two dose levels of micafungin for injection were evaluated in a randomized, double-blind study to determine the efficacy and safety versus caspofungin in patients with invasive candidiasis and candidemia. Patients were randomized to receive once daily intravenous infusions (IV) of micafungin for injection, either 100 mg/day or 150 mg/day or caspofungin (70 mg loading dose followed by 50 mg maintenance dose).
Patients in both study arms were permitted to switch to oral fluconazole after at least 10 days of intravenous therapy, provided they were non-neutropenic, had improvement or resolution of clinical signs and symptoms, had a Candida isolate which was susceptible to fluconazole, and had documentation of 2 negative cultures drawn at least 24 hours apart. Patients were stratified by APACHE II score (20 or less or greater than 20) and by geographic region. Patients with Candida endocarditis were excluded from this analysis.
Outcome was assessed by overall treatment success based on clinical (complete resolution or improvement in attributable signs and symptoms and radiographic abnormalities of the Candida infection and no additional antifungal therapy) and mycological (eradication or presumed eradication) response at the end of IV therapy. Deaths that occurred during IV study drug therapy were treated as failures. In this study, 111/578 (19.2%) of the patients had baseline APACHE II scores of greater than 20, and 50/578 (8.7%) were neutropenic at baseline (absolute neutrophil count less than 500 cells/mm 3 ).
Outcome, relapse and mortality data are shown for the recommended dose of micafungin for injection (100 mg/day) and caspofungin in Table 9. Table 9.
