Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will find how weight affects the dosing of a drug called caspofungin. Currently, the amount of caspofungin a patient receives is the same regardless of the patient's weight.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Capsofungin

Six volunteers will have a body mass index (BMI) less than 25 kg/m2, 6 will have a BMI 25-40 kg/m2, and 6 will have a BMI greater than 40 kg/m2.

Group Type EXPERIMENTAL

Caspofungin

Intervention Type DRUG

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Male and female subjects, age 18 years of age or older, of all racial and ethnic origins. English and/or Spanish speaking volunteers are eligible to participate.

Exclusion Criteria

* Pregnant or nursing or unwilling to use a reliable contraception method during the study. The effects of caspofungin on pregnancy are unknown. In addition, the metabolic changes that accompany pregnancy may alter the concentration-time profile of caspofungin, so that the pregnancy and post-partum state would be a confounding variable.
* Abnormal liver function tests: transaminases\>10 times upper limit of normal, Alkaline phosphatase\>5 times upper limit of normal, total bilirubin\>5 times upper limit of normal.
* History of allergies to echinocandins.
* Echinocandins are contraindicated for any reason.
* Volunteers unwilling to comply with study procedures.
* Suspected or documented systemic fungal infection.
* Concomitant use of rifamycins, tacrolimus, or cyclosporine
