This is a pilot feasibility study that investigates antifungal therapy with caspofungin in patients at high-risk for developing invasive candidiasis in a critical care setting.

Condition Intervention Phase
Invasive Candidiasis Drug: Caspofungin acetate Drug: Placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: MSG-04 (Also Known as Merck Caspofungin Protocol 067): A Pilot, Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial of Caspofungin Empirical Therapy for Invasive Candidiasis in High-Risk Patients in the Critical Care Setting

Primary Outcome Measures:
  • The Proportion of Patients Discontinued From Study Therapy to be Treated With Empirical Antifungal Therapy Outside of the Context of the Study. [ Time Frame: 1 to 14 days ]

    The feasibility of conducting a major randomized study of caspofungin for empirical therapy for invasive candidiasis in high-risk non-neutropenic intensive care unit (ICU) participants was to be assessed by the incidence of study therapy discontinuations due to investigators choosing to treat participants with empirical antifungal therapy outside of the context of this protocol.

    Study drug was administered for a minimum of 7 days to a maximum of 14 days provided participants had no evidence of confirmed breakthrough invasive Candida infection while receiving study drug.

Enrollment: 15
Study Start Date: December 2010
Study Completion Date: April 2012
Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Caspofungin
caspofungin acetate
Drug: Caspofungin acetate
70 mg of caspofungin administered intravenously (IV) on Day 1 followed by 50 mg daily for at least 6 additional days (maximum duration study therapy is 14 days)
Other Names:
  • caspofungin
  • MK-0991
  • Cancidas®
Placebo Comparator: Placebo
normal saline
Drug: Placebo
Placebo to caspofungin (normal saline) on Day 1 followed by placebo daily for at least 6 additional days (maximum duration study therapy is 14 days)
Other Name: normal saline

Detailed Description:
Hypothesis: In high-risk non-neutropenic participants in the ICU, the proportion of participants discontinued from study therapy in order to be empirically treated with antifungal therapy for suspected candidiasis outside of the context of this protocol is less than 20% (i.e., the upper bound of the 95% confidence interval for the observed proportion is less than 20%).
