Serial Therapeutic and Antifungal Monitoring Protocol (STAMP)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02163889
Recruitment Status : Completed

Brief Summary:

The objective of this study is to investigate T2Candida performance as a monitoring tool for post-therapy clearance of Candida compared to blood culture.

This study will collect a T2clinical specimen and companion blood culture from patients who have exhibited a positive blood culture by gram stain for yeast, and who are receiving treatment with antifungal therapy.

Condition or disease

Detailed Description:

One blood culture and one set of T2clinical specimens will be collected at specified intervals to monitor the clearance of Candida infection from the bloodstream.

Each T2 result will be compared to the companion blood culture result. The comparison will determine if the presence of antifungal therapy inhibits blood culture and leads to an incidence of blood culture false negative test results. The T2 result, which is not impacted by the presence of antifungal therapy, can show that the pathogen is still present for some additional period of time.

Study Type : Observational
Actual Enrollment : 31 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Serial Therapeutic and Antifungal Monitoring Protocol
Actual Study Start Date : September 2014
Actual Primary Completion Date : April 2017
Actual Study Completion Date : April 2017

Candida Positive Patients
Symptomatic adult patients, confirmed via blood culture with species identification to be positive for Candida

Primary Outcome Measures :
  1. Time to negative test result [ Time Frame: 14 days post enrollment ]
    The number of days to a negative test result will be compared between the T2Candida Test and blood culture.

Biospecimen Retention:   Samples With DNA
At each time point, three 4 ml whole blood specimens will be collected. One sample will be tested, and the remaining samples will be available for use in investigating discrepant T2Candida assay and blood culture results, or may be used for research purposes
