2.4 Directions For Reconstitution, Dilution, And Preparation

  • Do not mix or co-infuse micafungin for injection with other medications. Micafungin for injection has been shown to precipitate when mixed directly with a number of other commonly used medications. Please read this entire section carefully before beginning reconstitution.ReconstitutionReconstitute micafungin for injection vials by aseptically adding 5 mL of one of the following compatible solutions:0.9% Sodium Chloride Injection, USP (without a bacteriostatic agent)5% Dextrose Injection, USPTo minimize excessive foaming, gently dissolve the micafungin for injection powder by swirling the vial. Do not vigorously shake the vial. Visually inspect the vial for particulate matter.Micafungin for injection 50 mg vial: after reconstitution each mL contains 10 mg of micafungin.Micafungin for injection 100 mg vial: after reconstitution each mL contains 20 mg of micafungin.Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if there is any evidence of precipitation or foreign matter. Aseptic technique must be strictly observed in all handling since no preservative or bacteriostatic agent is present in micafungin for injection or in the materials specified for reconstitution and dilution.The reconstituted product should be protected from light and may be stored in the original vial for up to 24 hours at room temperature, 25°C (77°F). Dilution and PreparationThe diluted solution should be protected from light. It is not necessary to cover the infusion drip chamber or the tubing. Adult Patients:Add the appropriate volume of reconstituted micafungin for injection into 100 mL of 0.9% Sodium Chloride Injection, USP or 100 mL of 5% Dextrose Injection, USP.Appropriately label the bag.Pediatric Patients:Calculate the total micafungin for injection dose in milligrams (mg) by multiplying the recommended pediatric dose (mg/kg) for a given indication [see Table 2] and the weight of the patient in kilograms (kg).To calculate the volume (mL) of drug needed, divide the calculated dose (mg) from step 1 by the final concentration of the selected reconstituted vial(s) (either 10 mg/mL for the 50 mg vial or 20 mg/mL for the 100 mg vial), see example below:Using 50 mg vials: Divide the calculated mg dose (from step 1) by 10 mg/mL to determine the volume (mL) needed. ORUsing 100 mg vials: Divide the calculated mg dose (from step 1) by 20 mg/mL to determine the volume (mL) needed.Withdraw the calculated volume (mL) of drug needed from the selected concentration and size of reconstituted micafungin for injection vial(s) used in Step 2 (ensure the selected concentration and vial size used to calculate the dose is also used to prepare the infusion).Add the withdrawn volume of drug (step 3) to a 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP intravenous infusion bag or syringe. Ensure that the final concentration of the solution is between 0.5 mg/mL to 4 mg/mL. To decrease the risk of infusion reactions, concentrations above 1.5 mg/mL should be administered via central catheter [see Warnings and Precautions (5.5)].Appropriately label the infusion bag or syringe. For concentrations above 1.5 mg/mL, if required, label to specifically warn to administer the solution via central catheter.The diluted infusion bag should be protected from light and may be stored for up to 24 hours at room temperature, 25°C (77°F).  Micafungin for injection is preservative-free. Discard partially used vials.

2.5 Infusion Volume And Duration

Administer micafungin for injection by intravenous infusion only. Infuse over one hour. More rapid infusions may result in more frequent histamine-mediated reactions [see Warnings and Precautions (5.5)].Flush an existing intravenous line with 0.9% Sodium Chloride Injection, USP, prior to infusion of micafungin for injection. Pediatric Patients Micafungin for injection should be infused over one hour. To decrease the risk of infusion reactions, concentrations above 1.5 mg/mL should be administered via central catheter [see Warnings and Precautions (5.5)].

4 Contraindications

Micafungin for injection is contraindicated in persons with known hypersensitivity to micafungin, any component of micafungin for injection, or other echinocandins.

5.1 Hypersensitivity Reactions

Isolated cases of serious hypersensitivity (anaphylaxis and anaphylactoid) reactions (including shock) have been reported in patients receiving micafungin for injection. If these reactions occur, micafungin for injection infusion should be discontinued and appropriate treatment administered.

5.2 Hematological Effects

Acute intravascular hemolysis and hemoglobinuria was seen in a healthy volunteer during infusion of micafungin for injection (200 mg) and oral prednisolone (20 mg). Cases of significant hemolysis and hemolytic anemia have also been reported in patients treated with micafungin for injection. Patients who develop clinical or laboratory evidence of hemolysis or hemolytic anemia during micafungin for injection therapy should be monitored closely for evidence of worsening of these conditions and evaluated for the risk/benefit of continuing micafungin for injection therapy.

5.3 Hepatic Effects

Laboratory abnormalities in liver function tests have been seen in healthy volunteers and patients treated with micafungin for injection. In some patients with serious underlying conditions who were receiving micafungin for injection along with multiple concomitant medications, clinical hepatic abnormalities have occurred, and isolated cases of significant hepatic impairment, hepatitis, and hepatic failure have been reported. Patients who develop abnormal liver function tests during micafungin for injection therapy should be monitored for evidence of worsening hepatic function and evaluated for the risk/benefit of continuing micafungin for injection therapy.

5.4 Renal Effects

Elevations in BUN and creatinine, and isolated cases of significant renal impairment or acute renal failure have been reported in patients who received micafungin for injection. In fluconazole-controlled trials, the incidence of drug-related renal adverse reactions was 0.4% for micafungin for injection-treated patients and 0.5% for fluconazole-treated patients. Patients who develop abnormal renal function tests during micafungin for injection therapy should be monitored for evidence of worsening renal function.

5.5 Infusion And Injection Site Reactions

Possible histamine-mediated symptoms have been reported with micafungin for injection, including rash, pruritus, facial swelling, and vasodilatation. Slow the infusion rate if infusion reaction occurs.Injection site reactions, including phlebitis and thrombophlebitis have been reported, at micafungin for injection doses of 50 to 150 mg/day. These reactions tended to occur more often in patients receiving micafungin for injection via peripheral intravenous administration [see Adverse Reactions (6.1)].

6 Adverse Reactions

  • The following clinically significant adverse reactions are described elsewhere in the labeling:Hypersensitivity Reactions [see Warnings and Precautions (5.1)]Hematological Effects [see Warnings and Precautions (5.2)]Hepatic Effects [see Warnings and Precautions (5.3)]Renal Effects [see Warnings and Precautions (5.4)]Infusion and Injection Site Reactions [see Warnings and Precautions (5.5)]

6.1 Clinical Trials Experience

  • Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of micafungin for injection cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in practice. The overall safety of micafungin for injection was assessed in 520 health volunteers and 3,227 adult and pediatric patients who received single or multiple doses of micafungin for injection across 46 clinical trials, including the invasive candidiasis, esophageal candidiasis and prophylaxis trials. The doses of micafungin for injection administered included doses above and below the recommended doses [see Dosage and Administration (2.1, 2.2)] and ranged from 0.75 mg/kg to 10 mg/kg in pediatric patients and 12.5 mg to 150 mg/day or greater in adult patients.Clinical Trials Experience in AdultsIn clinical trials with micafungin for injection, 2,497/2,748 (91%) adult patients experienced at least one adverse reaction.Candidemia and Other Candida InfectionsIn a randomized, double-blind trial for the treatment of candidemia and other Candida infections, adverse reactions occurred in 183/200 (92%) and 171/193 (89%) patients in the micafungin for injection 100 mg/day and caspofungin (a 70 mg loading dose followed by a 50 mg/day dose) treatment groups, respectively. Selected treatment-emergent adverse reactions occurring in 5% or more of the patients and more frequently in the micafungin for injection treatment group, are shown in Table 3. Table 3.

Of the 479 pediatric patients, 264 (55%) were male, 319 (67%) were white, with the following age distribution: 116 (24%) to <2 years, 108 (23%) 2 to 5 years, 140 (29%) 6 to 11 years, and 115 (24%) 12 to 16 years of age. The mean treatment duration was 24.8 days. A total of 246 patients received at least one dose of micafungin for injection ranging from 2 to 10 mg/kg.  Overall, 439/479 (92%) patients experienced at least one adverse reaction. Adverse reactions occurring in >15% or more of micafungin-treated pediatric patients are: vomiting (31%), diarrhea (22%), pyrexia (22%), nausea (19%), abdominal pain (16%), and thrombocytopenia (15%). Two randomized, double-blind active-controlled trials  included pediatric patients. In the invasive candidiasis/candidemia trial, the efficacy and safety of micafungin for injection (2 mg/kg/day for patients weighing 40 kg or less and 100 mg/day for patients weighing greater than 40 kg) was compared to amphotericin B liposome (3 mg/kg/day) in 112 pediatric patients. Treatment-emergent adverse reactions occurred in 51/56 (91%) of patients in the micafungin for injection group and 52/56 (93%) of patients in the amphotericin B liposome group. Treatment-emergent adverse reactions resulting in drug discontinuation were reported in 2 (4%) micafungin for injection-treated pediatric patients and in 9 (16%) amphotericin B liposome-treated pediatric patients.The prophylaxis study in patients undergoing HSCT investigated the efficacy of micafungin for injection (1 mg/kg/day for patients weighing 50 kg or less and 50 mg/day for patients weighing greater than 50 kg) as compared to fluconazole (8 mg/kg/day for patients weighing 50 kg or less and 400 mg/day for patients weighing greater than 50 kg). All 91 pediatric patients experienced at least one treatment-emergent adverse reaction. Three (7%) pediatric patients discontinued micafungin for injection due to adverse reaction, while one (2%) patient discontinued fluconazole.Selected adverse reactions, occurring in 15% or more of the patients and more frequently in a micafungin for injection group, for for the two comparative trials are shown in Table 6.Table 6.

6.2 Postmarketing Adverse Reactions

  • The following adverse reactions have been identified during the post-approval use of micafungin for injection. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.Blood and lymphatic system disorders: disseminated intravascular coagulationHepatobiliary disorders: hepatic disorderRenal and urinary disorders: renal impairmentSkin and subcutaneous tissue disorders: Stevens-Johnson syndrome, toxic epidermal necrolysisVascular disorders: shock

7.1 Effect Of Other Drugs On Micafungin For Injection

CYP3A4, CYP2C9 and CYP2C19 InhibitorsCo-administration of micafungin for injection with cyclosporine, itraconazole, voriconazole and fluconazole did not alter the pharmacokinetics of micafungin for injection.CYP2C19 and CYP3A4 InducerCo-administration of micafungin for injection with rifampin and ritonavir did not alter the pharmacokinetics of micafungin for injection.Co-administration of Micafungin for Injection with Other DrugsCo-administration of micafungin for injection with mycophenolate mofetil (MMF), amphotericin B, tacrolimus, prednisolone, sirolimus and nifedipine did not alter the pharmacokinetics of micafungin for injection.

7.2 Effect Of Micafungin For Injection On Other Drugs

CYP3A4 SubstratesThere was no effect of single or multiple doses of micafungin for injection on cyclosporine, tacrolimus, prednisolone, voriconazole and fluconazole pharmacokinetics.Sirolimus AUC was increased by 21% with no effect on Cmax in the presence of steady-state micafungin for injection compared with sirolimus alone. Nifedipine AUC and Cmax were increased by 18% and 42%, respectively, in the presence of steady-state micafungin for injection compared with nifedipine alone. Itraconazole AUC and Cmax were increased by 22% and 11%, respectively. Patients receiving sirolimus, nifedipine, and itraconazole in combination with micafungin for injection should be monitored for sirolimus, nifedipine, and itraconazole toxicity and the sirolimus, nifedipine, and itraconazole dosage should be reduced if necessary.UDP-Glycosyltransferase SubstrateCo-administration of mycophenolate mofetil (MMF) with micafungin for injection did not alter the pharmacokinetics of MMF.

8.1 Pregnancy

Risk SummaryBased 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.DataAnimal DataIn 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.

8.2 Lactation

Risk SummaryThere 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.

8.4 Pediatric Use

  • Pediatric Patients 4 Months of Age and OlderThe 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 AgeTreatment of Candidemia, Acute Disseminated Candidiasis, Candida Peritonitis and Abscesses With Meningoencephalitis and/or Ocular Dissemination in Pediatric Patients Younger Than 4 Months of Age The safety and effectiveness of micafungin for injection have notbeen established for the treatment of candidemia with meningoencephalitis and/or ocular dissemination in pediatric patients younger than 4 months of age.In a rabbit model of hematogenous Candida meningoencephalitis (HCME) with Candida albicans (minimum inhibitory concentration of 0.125 mcg/mL), a decrease in mean fungal burden in central nervous system (CNS) compartments assessed as the average of combined fungal burden in the cerebrum, cerebellum, and spinal cord relative to untreated controls, was observed with increasing micafungin dosages administered once daily for 7 days. In this rabbit model, micafungin concentrations could not be reliably detected in cerebrospinal fluid (CSF). Due to limitations of the study design, the clinical significance of a decreased CNS fungal burden in the rabbit HCME model is uncertain.Treatment of Esophageal Candidiasis and Prophylaxis of Candida Infections in Patients Undergoing Hematopoietic Stem Cell Transplantation in Pediatric Patients Younger Than 4 Months of Age The safety and effectiveness of micafungin for injection in pediatric patients younger than 4 months of age have not been established for the:Treatment of esophageal candidiasisProphylaxis of Candida infections in patients undergoing hematopoietic stem cell transplantation Additional pediatric use information is approved for Astellas Pharma US Inc.’s Mycamine® (micafungin for injection).

8.5 Geriatric Use

A total of 418 subjects in clinical studies of micafungin for injection were 65 years of age and older, and 124 subjects were 75 years of age and older. No overall differences in safety and effectiveness were observed between these subjects and younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.The exposure and disposition of a 50 mg micafungin for injection dose administered as a single 1-hour infusion to 10 healthy subjects aged 66 to 78 years were not significantly different from those in 10 healthy subjects aged 20 to 24 years. No dose adjustment is necessary for the elderly.

8.6 Use In Patients With Renal Impairment

Micafungin for injection does not require dose adjustment in patients with renal impairment. Supplementary dosing should not be required following hemodialysis [see Clinical Pharmacology (12.3)].

8.7 Use In Patients With Hepatic Impairment

Dose adjustment of micafungin for injection is not required in patients with mild, moderate, or severe hepatic impairment [see Clinical Pharmacology (12.3)].

8.8 Race And Gender

No dose adjustment of micafungin for injection is required based on gender or race. After 14 daily doses of 150 mg to healthy subjects, micafungin AUC in women was greater by approximately 23% compared with men, due to smaller body weight. No notable differences among white, black, and Hispanic subjects were seen. The micafungin AUC was greater by 19% in Japanese subjects compared to blacks, due to smaller body weight.

9 Drug Abuse And Dependence

There has been no evidence of either psychological or physical dependence or withdrawal or rebound effects with micafungin for injection. .

10 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 10 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)].Additional pediatric use information is approved for Astellas Pharma US Inc.’s Mycamine® (micafungin for injection).

11 Description

Micafungin for injection is a sterile, lyophilized product for intravenous (IV) infusion that contains micafungin sodium. Micafungin sodium 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) or 100 mg micafungin (equivalent to 101.73 mg micafungin sodium), 200 mg lactose, with citric acid and/or sodium hydroxide (used for pH adjustment). Micafungin for injection 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 and 7. Micafungin sodium is chemically designated as: Pneumocandin A0,1-[(4R,5R)-4,5-dihydroxy-N2-[4-[5-[4-(pentyloxy)phenyl]-3-isoxazolyl]benzoyl]-L-ornithine]-4-[(4S)-4-hydroxy-4-[4-hydroxy-3-(sulfooxy)phenyl]-L-threonine]-, monosodium salt. The chemical structure of micafungin sodium is:                                                               The empirical/molecular formula is C56H70N9NaO23S and the formula weight is 1,292.26.Micafungin sodium is a light-sensitive, hygroscopic white powder that is freely soluble in water, isotonic sodium chloride solution, N,N-dimethylformamide and dimethylsulfoxide, slightly soluble in methyl alcohol, and practically insoluble in acetonitrile, ethyl alcohol (95%), acetone, diethyl ether and n-hexane.

12.1 Mechanism Of Action

Micafungin is a member of the echinocandin class of antifungal agents [see Microbiology (12.4)].

12.2 Pharmacodynamics

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)].

12.3 Pharmacokinetics

  • AdultsThe 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.

A single 1-hour infusion of 100 mg micafungin for injection was administered to 9 adult subjects with severe renal impairment (creatinine clearance less than 30 mL/min) and to 9 age-, gender-, and weight-matched subjects with normal renal function (creatinine clearance greater than 80 mL/min). The maximum concentration (Cmax) and AUC were not significantly altered by severe renal impairment. Since micafungin is highly protein bound, it is not dialyzable. Supplementary dosing should not be required following hemodialysis.Adult Patients with Hepatic ImpairmentA single 1-hour infusion of 100 mg micafungin for injection was administered to 8 adult subjects with moderate hepatic impairment (Child-Pugh score 7 to 9) and 8 age-, gender-, and weight-matched subjects with normal hepatic function. The Cmax and AUC values of micafungin were lower by approximately 22% in subjects with moderate hepatic impairment compared to normal subjects. This difference in micafungin exposure does not require dose adjustment of micafungin for injection in patients with moderate hepatic impairment.A single 1-hour infusion of 100 mg micafungin for injection was administered to 8 adult subjects with severe hepatic impairment (Child-Pugh score 10 to 12) and 8 age-, gender-, ethnic- and weight-matched subjects with normal hepatic function. The mean Cmax and AUC values of micafungin were lower by approximately 30% in subjects with severe hepatic impairment compared to normal subjects. The mean Cmax and AUC values of M-5 metabolite were approximately 2.3-fold higher in subjects with severe hepatic impairment compared to normal subjects; however, this exposure (parent and metabolite) was comparable to that in patients with systemic Candida infection. Therefore, no micafungin for injection dose adjustment is necessary in patients with severe hepatic impairment.DistributionThe mean ± standard deviation volume of distribution of micafungin at terminal phase was 0.39 ± 0.11 L/kg body weight when determined in adult patients with esophageal candidiasis at the dose range of 50 mg to 150 mg.Micafungin is highly (greater than 99%) protein bound in vitro, independent of plasma concentrations over the range of 10 to 100 mcg/mL. The primary binding protein is albumin; however, micafungin, at therapeutically relevant concentrations, does not competitively displace bilirubin binding to albumin. Micafungin also binds to a lesser extent to α1-acid-glycoprotein.Micafungin is neither a substrate nor an inhibitor of P-glycoprotein. MetabolismMicafungin is metabolized to M-1 (catechol form) by arylsulfatase, with further metabolism to M-2 (methoxy form) by catechol-O-methyltransferase. M-5 is formed by hydroxylation at the side chain (ω-1 position) of micafungin catalyzed by cytochrome P450 (CYP) isozymes. Even though micafungin is a substrate for and a weak inhibitor of CYP3A in vitro, hydroxylation by CYP3A is not a major pathway for micafungin metabolism in vivo. Micafungin is neither a P-glycoprotein substrate nor inhibitor in vitro. In four healthy volunteer studies, the ratio of metabolite to parent exposure (AUC) at a dose of 150 mg/day was 6% for M-1, 1% for M-2, and 6% for M-5. In patients with esophageal candidiasis, the ratio of metabolite to parent exposure (AUC) at a dose of 150 mg/day was 11% for M-1, 2% for M-2, and 12% for M-5.ExcretionThe excretion of radioactivity following a single intravenous dose of 14C-micafungin sodium for injection (25 mg) was evaluated in healthy volunteers. At 28 days after administration, mean urinary and fecal recovery of total radioactivity accounted for 82.5% (76.4% to 87.9%) of the administered dose. Fecal excretion is the major route of elimination (total radioactivity at 28 days was 71% of the administered dose).

12.4 Microbiology

Mechanism of ActionMicafungin inhibits the synthesis of 1, 3-beta-D-glucan, an essential component of fungal cell walls, which is not present in mammalian cells.Activity in Animal Models of CandidiasisActivity of micafungin has been demonstrated in both mucosal and disseminated murine and rabbit models of candidiasis. Micafungin administered to immunocompetent or immunosuppressed mice or rabbits with disseminated candidiasis prolonged survival (mice) and/or decreased the fungal burden in different organs including brain in a dose-dependent manner (mice and rabbits). Overall, antifungal activity of micafungin was demonstrated in the brain and eye tissues of nonneutropenic rabbits with HCME infected with a micafungin-sensitive strain of C. albicans; however, the activity varied in different central nervous system and ocular compartments. In the cerebrum, culture negativity was achieved at a micafungin dose regimen of 32 mg/kg once daily for 7 days; whereas, in spinal cord, vitreous humor, and choroid, culture negativity was achieved at micafungin dose regimens of 24 to 32 mg/kg once daily. Compared to untreated animals, micafungin dose regimens between 8 and 24 mg/kg once daily reduced fungal burden in the cerebrum and cerebellum. When cerebrum, cerebellum and spinal cord data were combined, a decrease in fungal burden relative to untreated controls was evident at micafungin dose regimens between 16 and 32 mg/kg once daily.ResistanceThere have been reports of clinical failures in patients receiving micafungin for injection therapy due to the development of drug resistance. Some of these reports have identified specific mutations in the FKS protein component of the glucan synthase enzyme that are associated with higher MICs and breakthrough infection.Antimicrobial ActivityMicafungin has been shown to be active against most isolates of the following Candida species, both in vitro and in clinical infections [see Indications and Usage (1)]:Candida albicans Candida glabrataCandida guilliermondii Candida krusei Candida parapsilosisCandida tropicalis Susceptibility Testing For specific information regarding susceptibility test interpretive criteria and associated test methods and quality control standards recognized by FDA for this drug, please see: https://www.fda.gov/STIC.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

Hepatic carcinomas and adenomas were observed in a 6-month intravenous toxicology study with an 18-month recovery period of micafungin sodium in rats designed to assess the reversibility of hepatocellular lesions. Rats administered micafungin sodium for 3 months at 32 mg/kg/day (corresponding to 8 times the highest recommended human dose [150 mg/day], based on AUC comparisons), exhibited colored patches/zones, multinucleated hepatocytes and altered hepatocellular foci after 1 or 3-month recovery periods, and adenomas were observed after a 21-month recovery period. Rats administered micafungin sodium at the same dose for 6 months exhibited adenomas after a 12-month recovery period; after an 18-month recovery period, an increased incidence of adenomas was observed and, additionally, carcinomas were detected. A lower dose of micafungin sodium (equivalent to 5 times the human AUC) in the 6-month rat study resulted in a lower incidence of adenomas and carcinomas following 18 months recovery. The duration of micafungin dosing in these rat studies (3 or 6 months) exceeds the usual duration of micafungin for injection dosing in patients, which is typically less than 1 month for treatment of esophageal candidiasis, but dosing may exceed 1 month for Candida prophylaxis. Although the increase in carcinomas in the 6-month rat study did not reach statistical significance, the persistence of altered hepatocellular foci subsequent to micafungin for injection dosing, and the presence of adenomas and carcinomas in the recovery periods suggest a causal relationship between micafungin sodium, altered hepatocellular foci, and hepatic neoplasms. Whole-life carcinogenicity studies of micafungin for injection in animals have not been conducted, and it is not known whether the hepatic neoplasms observed in treated rats also occur in other species, or if there is a dose threshold for this effect.Micafungin sodium was not mutagenic or clastogenic when evaluated in a standard battery of in vitro and in vivo tests (i.e., bacterial reversion - S. typhimurium, E. coli; chromosomal aberration; intravenous mouse micronucleus).Male rats treated intravenously with micafungin sodium for 9 weeks showed vacuolation of the epididymal ductal epithelial cells at or above 10 mg/kg (about 0.6 times the recommended clinical dose for esophageal candidiasis, based on body surface area comparisons). Higher doses (about twice the recommended clinical dose, based on body surface area comparisons) resulted in higher epididymis weights and reduced numbers of sperm cells. In a 39-week intravenous study in dogs, seminiferous tubular atrophy and decreased sperm in the epididymis were observed at 10 and 32 mg/kg, doses equal to about 2 and 7 times the recommended clinical dose, based on body surface area comparisons. There was no impairment of fertility in animal studies with micafungin sodium.

13.2 Animal Toxicology And/Or Pharmacology

High doses of micafungin sodium (5 to 8 times the highest recommended human dose, based on AUC comparisons) have been associated with irreversible changes to the liver when administered for 3 or 6 months, and these changes may be indicative of pre-malignant processes [see Nonclinical Toxicology (13.1)].

14.1 Treatment Of Candidemia And Other Candida Infections In Adult And Pediatric Patients 4 Months Of Age Or 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/mm3). 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.

14.2 Treatment Of Esophageal Candidiasis In Adult And Pediatric Patients 4 Months Of Age And Older

In two controlled trials involving 763 patients with esophageal candidiasis, 445 adults with endoscopically-proven candidiasis received micafungin for injection, and 318 received fluconazole for a median duration of 14 days (range 1 to 33 days).Micafungin for injection was evaluated in a randomized, double-blind study which compared micafungin for injection 150 mg/day (n = 260) to intravenous fluconazole 200 mg/day (n = 258) in adults with endoscopically-proven esophageal candidiasis. Most patients in this study had HIV infection, with CD4 cell counts less than 100 cells/mm3. Outcome was assessed by endoscopy and by clinical response at the end of treatment. Endoscopic cure was defined as endoscopic grade 0, based on a scale of 0 to 3. Clinical cure was defined as complete resolution in clinical symptoms of esophageal candidiasis (dysphagia, odynophagia, and retrosternal pain). Overall therapeutic cure was defined as both clinical and endoscopic cure. Mycological eradication was determined by culture, and by histological or cytological evaluation of esophageal biopsy or brushings obtained endoscopically at the end of treatment. As shown in Table 10, endoscopic cure, clinical cure, overall therapeutic cure, and mycological eradication were comparable for patients in the micafungin for injection and fluconazole treatment groups.Table 10.

The mycological outcome was determined in the per protocol (evaluable) population, including patients with confirmed esophageal candidiasis who received at least 10 doses of study drug, and had no major protocol violations.† Calculated as micafungin for injection – fluconazole.Most patients (96%) in this study had C. albicans isolated at baseline. The efficacy of micafungin for injection was evaluated in less than 10 patients with Candida species other than C. albicans, most of which were isolated concurrently with C. albicans.Relapse was assessed at 2 and 4 weeks post-treatment in patients with overall therapeutic cure at end of treatment. Relapse was defined as a recurrence of clinical symptoms or endoscopic lesions (endoscopic grade greater than 0). There was no statistically significant difference in relapse rates at either 2 weeks or through 4 weeks post-treatment for patients in the micafungin for injection and fluconazole treatment groups, as shown in Table 11.Table 11. Relapse of Esophageal Candidiasis at Week 2 and through Week 4 Post-Treatment in Patients with Overall Therapeutic Cure at the End of TreatmentRelapseMicafungin for Injection150 mg/dayn = 223Fluconazole200 mg/dayn = 220% Difference*(95% CI)Relapse† at Week 240 (17.9%)30 (13.6%)4.3% (-2.5, 11.1)Relapse† through Week 4 (cumulative) 73 (32.7%)62 (28.2%)4.6% (-4, 13.1)* Calculated as micafungin for injection – fluconazole; N = number of patients with overall therapeutic cure (both clinical and endoscopic cure at end-of-treatment);† Relapse included patients who died or were lost to follow-up, and those who received systemic anti-fungal therapy in the post-treatment period.In this study, 459 of 518 (88.6%) patients had oropharyngeal candidiasis in addition to esophageal candidiasis at baseline. At the end of treatment, 192/230 (83.5%) micafungin for injection-treated patients and 188/229 (82.1%) of fluconazole-treated patients experienced resolution of signs and symptoms of oropharyngeal candidiasis. Of these, 32.3% in the micafungin for injection group, and 18.1% in the fluconazole group (treatment difference = 14.2%; 95% confidence interval [5.6, 22.8]) had symptomatic relapse at 2 weeks post-treatment. Relapse included patients who died or were lost to follow-up, and those who received systemic antifungal therapy during the post-treatment period. Cumulative relapse at 4 weeks post-treatment was 52.1% in the micafungin for injection group and 39.4% in the fluconazole group (treatment difference 12.7%, 95% confidence interval [2.8, 22.7]).

14.3 Prophylaxis Of Candida Infections In Hematopoietic Stem Cell Transplant Recipients

In a randomized, double-blind study, micafungin for injection (50 mg IV once daily) was compared to fluconazole (400 mg IV once daily) in 882 [adult (791) and pediatric (91)] patients undergoing an autologous or syngeneic (46%) or allogeneic (54%) stem cell transplant. All pediatric patients, except 2 per group, received allogeneic transplants. The status of the patients’ underlying malignancy at the time of randomization was: 365 (41%) patients with active disease, 326 (37%) patients in remission, and 195 (22%) patients in relapse. The more common baseline underlying diseases in the 476 allogeneic transplant recipients were: chronic myelogenous leukemia (22%), acute myelogenous leukemia (21%), acute lymphocytic leukemia (13%), and non-Hodgkin’s lymphoma (13%). In the 404 autologous and syngeneic transplant recipients the more common baseline underlying diseases were: multiple myeloma (37.1%), non-Hodgkin’s lymphoma (36.4%), and Hodgkin's disease (15.6%). During the study, 198 of 882 (22.4%) transplant recipients had proven graft-versus-host disease; and 475 of 882 (53.9%) recipients received immunosuppressive medications for treatment or prophylaxis of graft-versus-host disease. Study drug was continued until the patient had neutrophil recovery to an absolute neutrophil count (ANC) of 500 cells/mm3 or greater or up to a maximum of 42 days after transplant. The average duration of drug administration was 18 days (range 1 to 51 days). Duration of therapy was slightly longer in the pediatric patients who received micafungin for injection (median duration 22 days) compared to the adult patients who received micafungin for injection (median duration 18 days).Successful prophylaxis was defined as the absence of a proven, probable, or suspected systemic fungal infection through the end of therapy (usually 18 days), and the absence of a proven or probable systemic fungal infection through the end of the 4-week post-therapy period. A suspected systemic fungal infection was diagnosed in patients with neutropenia (ANC less than 500 cells/mm3); persistent or recurrent fever (while ANC less than 500 cells/mm3) of no known etiology; and failure to respond to at least 96 hours of broad spectrum antibacterial therapy. A persistent fever was defined as four consecutive days of fever greater than 38ºC. A recurrent fever was defined as having at least one day with temperatures 38.5ºC or higher after having at least one prior temperature higher than 38ºC; or having two days of temperatures higher than 38ºC after having at least one prior temperature higher than 38ºC. Transplant recipients who died or were lost to follow-up during the study were considered failures of prophylactic therapy.Successful prophylaxis was documented in 80.7% of adult and pediatric micafungin for injection recipients, and in 73.7% of adult and pediatric patients who received fluconazole (7% difference [95% CI = 1.5, 12.5]), as shown in Table 12, along with other study endpoints. The use of systemic antifungal therapy post-treatment was 42% in both groups.The number of proven breakthrough Candida infections was 4 in the micafungin for injection and 2 in the fluconazole group. The efficacy of micafungin for injection against infections caused by fungi other than Candida has not been established.Table 12.
