MicroPhage S. Aureus / MSSA / MRSA Blood Culture Beta Trial

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: NCT00814151
Recruitment Status : Completed
First Posted : December 24, 2008
Last Update Posted : December 24, 2008
Information provided by:
MicroPhage, Inc.

Brief Summary:
In-vitro identification of S. aureus, methicillin-sensitive S. aureus (MSSA), and methicillin-resistant S. aureus (MRSA) from positive blood cultures by MicroPhage's bacteriophage-based diagnostic platform.

Condition or disease Intervention/treatment
Bacteremia Staphylococcal Infection Sepsis Infection Other: MicroPhage S. aureus / MSSA / MRSA Blood Culture Test (prototype)

Detailed Description:
This is a multi-center, preclinical study to investigate the effectiveness of the performance of MicroPhage S. aureus / MSSA/MRSA test direct for blood culture. There will be no patient consent, as this is a laboratory performance study on leftover specimens. The MicroPhage test will be compared to site standards (gold standard) and market-available tests with similar indications (comparators). MicroPhage will require data to be collected at 4 hours and 5 hours following the start of the MicroPhage test. The study will last 2-3 months, depending on the accrual rate of the institution.

Group/Cohort Intervention/treatment
Blood Culture positive specimens available within 24 hours of alarm.
Other: MicroPhage S. aureus / MSSA / MRSA Blood Culture Test (prototype)
In vitro diagnostic: The MicroPhage "Intervention" was to perform the MicroPhage diagnostic test to detect S. aureus in the blood culture sample and determine MSSA or MRSA status at 4 and 5 hours of test incubation. The "Intervention" results were not made available to the patient or their physician.

Standard of Care
Blood Culture positive specimens.

Primary Outcome Measures :
  1. Determination of clinical performance of preliminary MicroPhage S. aureus/MSSA/MRSA test directly from clinical blood culture positives. [ Time Frame: Within 48 hours ]

Secondary Outcome Measures :
  1. Qualitative feedback on the preliminary MicroPhage test protocol.
  2. Comparative results to market-available S. aureus / MRSA tests for Blood Culture. [ Time Frame: Within 48 hours ]

Biospecimen Retention:   Samples Without DNA
Retention of discrepant blood culture specimens only.
