Clinical Evaluation of QFlu Combo Test (QFlu)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

Currently effective antivials for influenza treatment are two influenza viral neuraminidase inhibitors, oseltamivir (Tamiflu) and zanamivir (Relenza). Resistance to these drugs is reflected by reduced susceptibility of viral neuraminidase to these drugs. The hypothesis is that the signal ratio of two reagents (with or without a single concentration of the drug) correlates the IC50 value, an accurate measurement of drug resistance but impractical for clinical use.

Further study details as provided by Cellex, Inc.:

Primary Outcome Measures:
  • Sensitivity and specificity for drug resistance detection [ Time Frame: approximately 12 months after the study is completed. ]
    Interim results may be assessed after the first year study.

Secondary Outcome Measures:
  • Sensitivity and Specificity of the Test for Influenza Diagnosis [ Time Frame: 12 months after the study is completed. ]
    Results may be assessed after the first year study.

Biospecimen Retention:   Samples Without DNA
Samples were retained in case that the testing needs to be repeated. They are to be discarded 12 months after the study is completed.

Estimated Enrollment: 1000
Study Start Date: November 2010
Estimated Study Completion Date: July 2012
Estimated Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
General population
This group of participants is primarily an out-patient population.
In-patient population
This group of participants is primarily an in-patient population.
Pediatric Group
Participants in this group are children 18 years or younger.

Detailed Description:
The study design is to collect samples from participants. A portion of the sample is used for drug resistance detection using the test (QFlu Combo Test) under investigation. The remaining portion of the sample is used for culture. The culture positive samples are used for determination of IC50 values, which is used as a gold standard for defining whether a virus isolate is resistant to a drug or not. The sensitivity and specificity of the QFlu test will be calculated by comparing to the gold standard test.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
There are three population of participants: pediatric (in patient or out patient), in-patient (any age) and out-patient (any age).

Inclusion Criteria:

  • Those who exhibit flu-like symptom(s) during a flu season and who (or whose guardians) are willing to participate in the study.
