6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Clinical Trials Experience in Adults The safety of ERAXIS for Injection was assessed in 929 individuals, including 257 healthy subjects and 672 patients in clinical trials of candidemia, other forms of Candida infections, and esophageal candidiasis.
A total of 633 patients received ERAXIS at daily doses of either 50 mg or 100 mg. A total of 481 patients received ERAXIS for ≥14 days. Candidemia/other Candida Infections Three trials (one comparative vs. fluconazole, two non-comparative) assessed the efficacy and safety of ERAXIS (100 mg) in patients with candidemia and other Candida infections.
The data described below reflect exposure to ERAXIS and fluconazole in 127 and 118 patients, respectively, with candidemia and other forms of invasive candidiasis, in the randomized, comparative trial of the efficacy and safety of ERAXIS to that of fluconazole. In ERAXIS-treated patients, the age range was 16–89 years, the gender distribution was 51% male and 49% female, and the race distribution was 72% White, 18% Black/African American, 9% other races. Patients were randomized to receive once daily IV ERAXIS (200 mg loading dose followed by 100 mg maintenance dose) or IV fluconazole (800 mg loading dose followed by 400 mg maintenance dose).
Treatment was administered for at least 14 and not more than 42 days. The number of patients with adverse reactions leading to discontinuation of study medication was 11.5% in the ERAXIS arm and 21.6% in the fluconazole arm. The most common adverse reactions leading to study drug discontinuation were multi-organ failure (2.3%) and systemic Candida infection (1.5%) in the ERAXIS arm.
Table 2 presents adverse reactions that were reported in ≥5% of subjects receiving ERAXIS or fluconazole therapy in this trial. Table 2: Adverse Reactions Reported in ≥5% of Adult Patients Receiving ERAXIS or Fluconazole Therapy for Candidemia/other Candida Infections A patient who experienced multiple reactions within a Body System or preferred term was counted one time for that class, one time for the preferred term and one time for "subjects with at least one adverse reaction". , This trial was not designed to support comparative claims for ERAXIS for the adverse reactions reported in this table.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS • Pregnancy : Based on findings from animal studies, ERAXIS can cause fetal harm when administered to a pregnant woman. Inform pregnant woman of the risk to the fetus. ( 8.1 ) • Pediatric Use : The safety and effectiveness in patients younger than 1 month of age has not been established. ( 8.4 )
8.1Pregnancy Risk Summary Based on findings from animal studies, ERAXIS can cause fetal harm when administered to a pregnant woman. There are no available human data on the use of ERAXIS in pregnant women to inform a drug-associated risk of adverse developmental outcomes. In animal reproduction studies fetal toxicity was observed in the presence of maternal toxicity when anidulafungin was administered to pregnant rabbits during organogenesis at 4 times the proposed therapeutic maintenance dose of 100 mg/day on the basis of relative body surface area ( see Data ) .
Inform pregnant woman of the risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated populations are 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 a combined fertility and embryo-fetal development study in rats dosed with anidulafungin for 4 weeks prior to cohabitation and through cohabitation for males or for 2 weeks prior to cohabitation and continuing through gestation day 19 for females, there was no maternal or embryo-fetal toxicity at intravenous doses up to 20 mg/kg/day (equivalent to 2 times the proposed therapeutic maintenance dose of 100 mg/day on the basis of relative body surface area).
In a rabbit embryo-fetal development study, intravenous administration of anidulafungin (0, 5, 10, and 20 mg/kg/day) from gestation day 7 through 19, resulted in reduced fetal weights and incomplete ossification in the presence of maternal toxicity (decreased body weight gain) at 20 mg/kg/day (equivalent to 4 times the proposed therapeutic maintenance dose of 100 mg/day on the basis of relative body surface area). In a pre- and postnatal development study, pregnant rats were intravenously administered anidulafungin at doses of 2, 6, or 20 mg/kg/day from gestation day 7 through lactation day 20.
Maternal toxicity was observed at ≥6 mg/kg/day (clinical signs at ≥6 mg/kg/day and reduced body weight gain and food consumption during gestation at 20 mg/kg/day group). There were no effects on the viability or growth and development of the offspring. In this study, anidulafungin was detected in fetal plasma, indicating that it crossed the placental barrier.
8.2Lactation Risk Summary There are no data on the presence of anidulafungin in human milk, the effects on the breastfed infant or the effects on milk production. When a drug is present in animal milk, it is likely that the drug will be present in human milk. Anidulafungin was found in the milk of lactating rats ( see Data ).
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ERAXIS and any potential adverse effects on the breastfed child from ERAXIS or from the underlying maternal condition. Data Animal Data Pregnant rats were intravenously administered anidulafungin at doses of 2, 6, or 20 mg/kg/day from gestation day 7 through lactation day 20. Milk samples were collected from 5 rats per group on lactation day 14 at approximately 1 hours post dose.
Approximately dose-proportional anidulafungin concentrations were found in the milk of lactating rats.
8.4Pediatric Use The safety and effectiveness of ERAXIS for the treatment of candidemia and the following Candida infections: intra-abdominal abscess and peritonitis, have been established in pediatric patients 1 month of age and older. Use of ERAXIS for this indication in this age group is suppor…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of ERAXIS for the treatment of candidemia and the following Candida infections: intra-abdominal abscess and peritonitis, have been established in pediatric patients 1 month of age and older. Use of ERAXIS for this indication in this age group is supported by evidence from adequate and well-controlled studies in adults with additional pharmacokinetic, safety data in pediatric patients 1 month of age and older [see Indications and Usage (1) , Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14.1) ].
The safety and effectiveness of ERAXIS in patients younger than 1 month of age with candidemia/invasive candidiasis has not been established. Candidemia/invasive candidiasis in pediatric patients younger than 1 month of age has a higher rate of central nervous system (CNS) and multi-organ dissemination than in older patients. In addition, in patients younger than 1 month of age ERAXIS carries a potential risk of life-threatening toxicity associated with high doses of polysorbate 80, an inactive ingredient in ERAXIS [see Warnings and Precautions (5.3) ] .
The safety and effectiveness of ERAXIS in pediatric patients with esophageal candidiasis has not been established. ERAXIS is contraindicated in adult and pediatric patients with HFI. Because a diagnosis of HFI may not yet be established in pediatric patients, obtain a careful history of HFI symptoms with fructose/sucrose exposure prior to administration of ERAXIS [see Warnings and Precautions (5.4) ] .
🧓 Geriatric Use ▾
8.5Geriatric Use Of the total number of subjects (N = 197) in the pivotal clinical studies of anidulafungin, 35% were 65 years and over, while 18% were 75 years and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and 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. Dosage adjustments are not required for geriatric patients [see Clinical Pharmacology (12.3) ] .
🆘 Overdosage ▾
10 OVERDOSAGE During clinical trials a single 400 mg dose of ERAXIS was inadvertently administered as a loading dose. No clinical adverse events were reported. In a study of 10 healthy subjects administered a loading dose of 260 mg followed by 130 mg daily; 3 of the 10 subjects experienced transient, asymptomatic transaminase elevations (≤3 × ULN) [see Warnings and Precautions (5.1) ] .
Anidulafungin is not dialyzable. The maximum non-lethal dose of anidulafungin in rats was 50 mg/kg, a dose which is equivalent to 10 times the recommended daily dose for esophageal candidiasis (50 mg/day) or equivalent to 5 times the recommended daily dose for candidemia and other Candida infections (100 mg/day), based on relative body surface area comparisons.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Anidulafungin is an anti-fungal drug [see Microbiology (12.4) ].
12.3Pharmacokinetics General Pharmacokinetic Characteristics The pharmacokinetics of anidulafungin following intravenous (IV) administration of ERAXIS have been characterized in healthy subjects, special populations and patients. Systemic exposures of anidulafungin are dose-proportional and have low inter-subject variability (coefficient of variation <25%) as shown in Table 5. The steady state was achieved on the first day after a loading dose (twice the daily maintenance dose) and the estimated plasma accumulation factor at steady state is approximately 2.

Distribution The pharmacokinetics of anidulafungin following IV administration are characterized by a short distribution half-life (0.5–1 hour) and a volume of distribution of 30–50 L that is similar to total body fluid volume. Anidulafungin is extensively bound (>99%) to human plasma proteins. Metabolism Hepatic metabolism of anidulafungin has not been observed.
Anidulafungin is not a clinically relevant substrate, inducer, or inhibitor of cytochrome P450 (CYP450) isoenzymes. It is unlikely that anidulafungin will have clinically relevant effects on the metabolism of drugs metabolized by CYP450 isoenzymes. Anidulafungin undergoes slow chemical degradation at physiologic temperature and pH to a ring-opened peptide that lacks antifungal activity.
The in vitro degradation half-life of anidulafungin under physiologic conditions is about 24 hours. In vivo , the ring-opened product is subsequently converted to peptidic degradants and eliminated. Excretion In a single-dose clinical study, radiolabeled ( 14 C) anidulafungin was administered to healthy subjects.
Approximately 30% of the administered radioactive dose was eliminated in the feces over 9 days, of which less than 10% was intact drug. Less than 1% of the administered radioactive dose was excreted in the urine. Anidulafungin concentrations fell below the lower limits of quantitation 6 days post-dose.
Negligible amounts of drug-derived radioactivity were recovered in blood, urine, and feces 8 weeks post-dose. Specific Populations Patients with fungal infections Population pharmacokinetic analyses from four clinical trials including 107 male and 118 female patients with fungal infections showed that the pharmacokinetic parameters of anidulafungin are not affected by age, race, or the presence of concomitant medications which are known metabolic substrates, inhibitors or inducers. The pharmacokinetics of anidulafungin in patients with fungal infections are similar to those observed in healthy subjects.
The pharmacokinetic parameters of anidulafungin estimated using population pharmacokinetic modeling following IV administration of a maintenance dose of 50 mg/day or 100 mg/day (following a loading dose) of ERAXIS are presented in Table 6.

📋 Description ▾
11 DESCRIPTION ERAXIS for Injection is a sterile, lyophilized product for intravenous (IV) infusion that contains anidulafungin. ERAXIS (anidulafungin) is a semi-synthetic lipopeptide synthesized from a fermentation product of Aspergillus nidulans . Anidulafungin is an echinocandin, a class of antifungal drugs that inhibits the synthesis of 1,3-β-D-glucan, an essential component of fungal cell walls.
ERAXIS (anidulafungin) is 1-[(4R,5R)-4,5-dihydroxy-N 2 -[[4"-(pentyloxy)[1,1':4',1"-terphenyl]-4-yl]carbonyl]-L-ornithine]echinocandin B. Anidulafungin is a white to off-white powder that is practically insoluble in water and slightly soluble in ethanol. In addition to the active ingredient, anidulafungin, ERAXIS for Injection contains the following inactive ingredients: 50 mg/vial – fructose (50 mg), mannitol (250 mg), polysorbate 80 (125 mg), tartaric acid (5.6 mg), and sodium hydroxide and/or hydrochloric acid for pH adjustment.
100 mg/vial – fructose (100 mg), mannitol (500 mg), polysorbate 80 (250 mg), tartaric acid (11.2 mg), and sodium hydroxide and/or hydrochloric acid for pH adjustment. The empirical formula of anidulafungin is C 58 H 73 N 7 O 17 and the formula weight is 1140.3. The structural formula is: Prior to administration, ERAXIS for Injection requires reconstitution with sterile Water for Injection and subsequent dilution with either 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP (normal saline).
