Primary Outcome Measures:
  • Total Clearance of Caspofungin [ Time Frame: 0-72 hours (0, 1, 8, 16, 24, 48, and 72 hours) ] [ Designated as safety issue: No ]

Enrollment: 18
Study Start Date: February 2010
Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 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.
Drug: Caspofungin
Caspofungin 70mg IV (each volunteer will only receive one dose of the study drug)
Other Name: Cancidas


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

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
