Details with Side Effects
Laboratory abnormalities in liver function tests have been seen in healthy volunteers and patients treated with ERAXIS. In some patients with serious underlying medical conditions who were receiving multiple concomitant medications along with ERAXIS, clinically significant hepatic abnormalities have occurred. Isolated cases ofsignificant hepatic dysfunction, hepatitis, or hepatic failure have been reported in patients; a causal relationship to ERAXIS has not been established. Patients who develop abnormal liver function tests during ERAXIS therapy should be monitored for evidence of worsening hepatic function and evaluated for risk/benefit of continuing ERAXIS therapy.
Infusion-related adverse reactions, possibly histamine-mediated, have been reported with ERAXIS, including rash, urticaria, flushing, pruritus, bronchospasm, dyspnea, and hypotension [see ADVERSE REACTIONS]. To reduce occurrence of these reactions, do not exceed a rate of ERAXIS infusion of 1.1 mg/minute [see DOSAGE AND ADMINISTRATION].
Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term animal carcinogenicity studies of anidulafungin have not been conducted.
Anidulafungin was not genotoxic in the following in vitro studies: bacterial reverse mutation assays, a chromosome aberration assay with Chinese hamster ovary cells, and a forward gene mutation assay with mouse lymphoma cells. Anidulafungin was not genotoxic in mice using the in vivo micronucleus assay.
Anidulafungin produced no adverse effects on fertility in male or female rats at intravenous doses of 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).
Use In Specific Populations
Pregnancy Category B
Embryo-fetal development studies were conducted with doses up to 20 mg/kg/day in rats and rabbits (equivalent to 2 and 4 times, respectively, the proposed therapeutic maintenance dose of 100 mg/day on the basis of relative body surface area). In rats, anidulafungin crossed the placental barrier, was detected in fetal plasma, and was associated with incomplete ossification of several bones. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, ERAXIS should be used during pregnancy only if clearly needed.
Anidulafungin was found in the milk of lactating rats. It is not known whether anidulafungin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when ERAXIS is administered to a nursing woman.
The safety and effectiveness of ERAXIS in patients ≤ 16 years old has not been established [see CLINICAL PHARMACOLOGY].
Dosage adjustments are not required for geriatric patients [see CLINICAL PHARMACOLOGY].
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.
No dosing adjustments are required for patients with any degree of hepatic insufficiency. Anidulafungin is not hepatically metabolized. Anidulafungin pharmacokinetics were examined in subjects with Child-Pugh class A, B or C hepatic insufficiency. Anidulafungin concentrations were not increased in subjects with any degree of hepatic insufficiency. Though a slight decrease in AUC was observed in patients with Child-Pugh C hepatic insufficiency, it was within the range of population estimates noted for healthy subjects [see CLINICAL PHARMACOLOGY].
Dosage adjustments are not required for patients with any degree of renal insufficiency including those on dialysis. Anidulafungin has negligible ( < 1%) renal clearance. In a clinical study of subjects with mild, moderate, severe or end stage (dialysis-dependent) renal insufficiency, anidulafungin pharmacokinetics were similar to those observed in subjects with normal renal function. Anidulafungin is not dialyzable and may be administered without regard to the timing of hemodialysis [see CLINICAL PHARMACOLOGY].
