Evaluation of the Performance of Chembio's DPP(R) Syphilis Screen &

Status Withdrawn

Clinical Trial Summary

This study has been designed to evaluate the performance of the Chembio Diagnostics Systems, Inc. DPP® Syphilis Screen and Confirm rapid test. The device is intended to qualitatively and simultaneously detect the presence of antibodies to Non-treponemal and Treponema pallidum antigens in whole blood (capillary and venous), serum or plasma.

Clinical Trial Description

Syphilis is a sexually transmitted disease (STD) caused by the spirochete Treponema pallidum. It is a chronic bacterial infection that remains a public health concern worldwide, especially in resource poor settings. Syphilis can be transmitted from infected women to their unborn children during pregnancy. Worldwide 12 million individuals are diagnosed with syphilis each year, 90% of them in developing countries. Diagnosed individuals are also at risk of becoming infected with and transmitting HIV [1].

Early and appropriate diagnosis and treatment prevents the transmission and development of severe complications. A rapid serologic test for specific antibodies to non-Treponemal and T. pallidum antigens is important in the early diagnosis and treatment monitoring of syphilis patients. In turn, this monitoring allows for the formulation of a more successful public health strategy. Various serologic tests are currently available such as Venereal Disease Research Laboratory (VDRL), rapid plasma reagin (RPR), fluorescent Treponemal antibody absorption (FTA-ABS) test, T. pallidum hemagglutination (TPHA) test, immunoenzymatic assay (EIA), Treponema pallidum particle agglutination (TPPA) test and Western blot (WB) test [2- 5]. The Chembio DPP Syphilis Screen & Confirm Assay is a unique non-Treponemal and Treponemal rapid point-of-care test, which is simple and easy to use. The DPP Syphilis Screen & Confirm Assay is a qualitative immunoassay for the detection of antibodies to the non-Treponemal and T. pallidum antigens in serum, plasma and whole blood. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
