The overall goal of the present study is to provide evidence of concordant test results using the Identigene STD Test Collection Kit for self-collection and transport of specimens to a qualified testing laboratory. It is expected that this method will aid in detection of CT and NG and that offering a method of self-collection of a male urine or female vaginal swab specimen will encourage testing for CT and NG and improve the overall detection of reporting of these STDs by allowing persons who suspect they have the infection to be tested in a discrete and confidential manner. The reporting of CT and NG are underestimated and many subjects will not visit a clinic or obtain treatment if gone undetected. Thus, allowing a self-collection kit that is more convenient may result in improved reporting, identification of CT and NG positive individuals, and subsequent treatment to help prevent the spread of these diseases. The purpose of this study is to demonstrate that the Identigene STD Test Collection Kit and labeled instructions for use instructions provide test results that are concordant (at least 95% or better) with test results obtained using the Gen-Probe APTIMA Combo 2 specimen collection and transport methods performed under the supervision of a healthcare provider. The laboratory technology and test method used for the IDTG-100.

This is a multicenter study involving asymptomatic and symptomatic subjects who are at risk or suspect possible exposure to CT and/or NG. Approximately five (5) clinics will participate in the study. The clinics selected will be located in diverse geographical regions in order to represent populations with both high and low incidences of CT and NG and to represent different extremes in climate. The initial phase of the study enrolled approximately 500 qualifying subjects. An interim analysis was performed to determine whether changes in the study protocol were necessary. Changes to the protocol were identified and are incorporated in this amendment (amendment 4) of the study protocol. Specifically, males in the study will still collect urine specimens whereas women will now self-collect a vaginal swab specimen. Study subjects will only undergo one clinic visit rather than two as indicated in prior versions of the study protocol. The proposed study phases outlined in this amendment of the study protocol will include at least 200 qualifying subjects with intermittent suspension of the study to allow data analysis. The present study will continue until 200 CT positive test results (approximately 100 male and 100 female) are obtained. Of these 200 positive results, approximately 50% will be from symptomatic subjects and 50% from asymptomatic subjects. Since the positivity rate is presumably lower for asymptomatic subjects, the ration of symptomatic to asymptomatic subject enrollment for each study phase will be determined by the sponsor and will be made known in writing to each study site. It is expected that approximately 3,000 subjects will be required to meet the overall study objectives. It is anticipated that the total number of subjects enrolled for testing throughout the study will yield approximately 30 positive NG samples (approximately 15 males and 15 females) with no requirement for a specific ratio of symptomatic to asymptomatic subjects. Subjects who are at high risk of exposure or suspect exposure to CT or NG, but are not currently being treated, will be recruited for enrollment.
