Caspofungin Acetate (Page 3 of 7)

6.2 Postmarketing Experience

The following additional adverse reactions have been identified during the post-approval use of caspofungin. 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.
• Gastrointestinal disorders: pancreatitis
• Hepatobiliary disorders: hepatic necrosis
• Skin and subcutaneous tissue disorders: erythema multiforme, toxic epidermal necrolysis, Stevens-Johnson syndrome, and skin exfoliation
• Renal and urinary disorders: clinically significant renal dysfunction
• General disorders and administration site conditions: swelling and peripheral edema• Laboratory abnormalities: gamma-glutamyltransferase increased


Cyclosporine: In two adult clinical studies, cyclosporine (one 4 mg/kg dose or two 3 mg/kg doses) increased the AUC of caspofungin. Caspofungin did not increase the plasma levels of cyclosporine. There were transient increases in liver ALT and AST when caspofungin and cyclosporine were co-administered. Monitor patients who develop abnormal liver enzymes during concomitant therapy and evaluate the risk/benefit of continuing therapy [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.3)].
Tacrolimus : For patients receiving caspofungin and tacrolimus, standard monitoring of tacrolimus trough whole blood concentrations and appropriate tacrolimus dosage adjustments are recommended.

Inducers of Hepatic CYP Enzymes
Rifampin: Rifampin is a potent CYP3A4 inducer and concomitant administration with caspofungin is expected to reduce the plasma concentrations of caspofungin. Therefore, adult patients on rifampin should receive 70 mg of caspofungin daily and pediatric patients on rifampin should receive 70 mg/m2 of caspofungin daily (not to exceed an actual daily dose of 70 mg) [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)].

Other Inducers of Hepatic CYP Enzymes
Adults: When caspofungin is co-administered to adult patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, administration of a daily dose of 70 mg of caspofungin should be considered [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)].

Pediatric Patients: When caspofungin is co-administered to pediatric patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, administration of a daily dose of 70 mg/m2 caspofungin (not to exceed an actual daily dose of 70 mg) should be considered [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)].


8.1 Pregnancy

Risk Summary
Based on animal data, caspofungin may cause fetal harm (see Data). There are insufficient human data to establish whether there is a drug-associated risk for major birth defects, miscarriage, or adverse maternal or fetal outcomes with caspofungin use in pregnant women.

In animal studies, caspofungin caused embryofetal toxicity, including increased resorptions, increased peri-implantation loss, and incomplete ossification at multiple fetal sites when administered intravenously to pregnant rats and rabbits during organogenesis at doses up to 0.8 and 2 times the clinical dose, respectively (see Data). Advise patients of the potential risk to the fetus.

The estimated background risk of major birth defects and miscarriage for the indicated population 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.

Animal Data
In animal reproduction studies, pregnant rats dosed intravenously with caspofungin during organogenesis (gestational days [GD] 6 to 20) at 0.5, 2, or 5 mg/kg/day (up to 0.8 times the clinical dose based on body surface area comparison) showed increased resorptions and peri-implantation losses at 5 mg/kg/day. Incomplete ossification of the skull and torso and increased incidences of cervical rib were noted in offspring born to pregnant rats treated at doses up to 5 mg/kg/day. In pregnant rabbits treated with intravenous caspofungin during organogenesis (GD 7 to 20) at doses of 1, 3, or 6 mg/kg/day (approximately 2 times the clinical dose based on body surface area comparison), increased fetal resorptions and increased incidence of incomplete ossification of the talus/calcaneus in offspring were observed at the highest dose tested. Caspofungin crossed the placenta in rats and rabbits and was detectable in fetal plasma.

In peri- and postnatal development study in rats, intravenous caspofungin administered at 0.5, 2 or 5 mg/kg/day from Day 6 of gestation through Day 20 of lactation was not associated with any adverse effects on reproductive performance or subsequent development of first generation (F1) offspring or malformations in second generation (F2) offspring.

8.2 Lactation

Risk Summary
There are no data on the presence of caspofungin in human milk, the effects on the breast-fed child, or the effects on milk production. Caspofungin was found in the milk of lactating, drug-treated rats.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for caspofungin and any potential adverse effects on the breastfed child from caspofungin or from the underlying maternal condition.

8.4 Pediatric Use

The safety and effectiveness of caspofungin in pediatric patients 3 months to 17 years of age are supported by evidence from adequate and well-controlled studies in adults, pharmacokinetic data in pediatric patients, and additional data from prospective studies in pediatric patients 3 months to 17 years of age for the following indications [see Indications and Usage (1)]:
• Empirical therapy for presumed fungal infections in febrile, neutropenic patients.
• Treatment of candidemia and the following Candida infections: intra-abdominal abscesses, peritonitis, and pleural space infections.
• Treatment of esophageal candidiasis.
• Treatment of invasive aspergillosis in patients who are refractory to or intolerant of other therapies (e.g., amphotericin B, lipid formulations of amphotericin B, itraconazole).
The efficacy and safety of caspofungin has not been adequately studied in prospective clinical trials involving neonates and infants under 3 months of age. Although limited pharmacokinetic data were collected in neonates and infants below 3 months of age, these data are insufficient to establish a safe and effective dose of caspofungin in the treatment of neonatal candidiasis. Invasive candidiasis in neonates has a higher rate of CNS and multi-organ involvement than in older patients; the ability of caspofungin to penetrate the blood-brain barrier and to treat patients with meningitis and endocarditis is unknown.

Caspofungin has not been studied in pediatric patients with endocarditis, osteomyelitis, and meningitis due to Candida. Caspofungin has also not been studied as initial therapy for invasive aspergillosis in pediatric patients.

In clinical trials, 171 pediatric patients (0 months to 17 years of age), including 18 patients who were less than 3 months of age, were given intravenous caspofungin. Pharmacokinetic studies enrolled a total of 66 pediatric patients, and an additional 105 pediatric patients received caspofungin in safety and efficacy studies [see Clinical Pharmacology (12.3 ) and Clinical Studies (14.5)]. The majority of the pediatric patients received caspofungin at a once-daily maintenance dose of 50 mg/m2 for a mean duration of 12 days (median 9, range 1 to 87 days). In all studies, safety was assessed by the investigator throughout study therapy and for 14 days following cessation of study therapy. The most common adverse reactions in pediatric patients treated with caspofungin were pyrexia (29%), blood potassium decreased (15%), diarrhea (14%), increased aspartate aminotransferase (12%), rash (12%), increased alanine aminotransferase (11%), hypotension (11%), and chills (11%) [see Adverse Reactions (6.2)]. Postmarketing hepatobiliary adverse reactions have been reported in pediatric patients with serious underlying medical conditions [see Warnings and Precautions (5.3)].
