Trial Outcomes & Findings for Clinical Study of a Single-Use, Point-of-Care Molecular Diagnostic Device for the Detection of Neisseria Gonorrhoeae (NG), Trichomonas Vaginalis (TV), and Chlamydia Trachomatis (CT) Utilizing Vaginal Swabs (NCT NCT03596151)

NCT ID: NCT03596151

Last Updated: 2021-08-24

Results Overview

The sensitivity of the Click device is defined as follows: TP = the number of specimens where both the Click result and the PIS designation are Positive; FN = the number of specimens where the Click result is Negative and the PIS designation is Positive; Sensitivity = 100 \* TP / (TP + FN) The specificity of the Click device is defined as follows: TN = the number of specimens where both the Click result and the PIS designation are Negative; FP = the number of specimens where the Click result is Positive and the PIS designation is Negative; Specificity = 100 \* TN / (TN + FP)

Click Device
The study population was comprised of female participants \>=14 years of age who visited any of the participating clinics for any reason, who may have been symptomatic or asymptomatic for STIs at locations including but not limited to: OB/GYN and primary care offices, as well as sexually transmitted disease, teen, public health, and family planning clinics. Participants who met the inclusion/exclusion criteria were offered enrollment into the study. Participants who enrolled in the study provided clinical and demographic information, performed self-collection with a vaginal swab for the Click device, and allowed the health care professional (HCP) to collect three additional vaginal swabs for the comparator methods. Participants completed the study in a single visit.

PRIMARY outcome

Timeframe: Day 1

Population: This population includes all participants with samples that provide an evaluable Click Diagnostics Sexual Health Test result and an evaluable PIS result for CT. An evaluable result is indicated if both the Click device and the PIS provide a valid positive or negative result.

The sensitivity of the Click device is defined as follows: TP = the number of specimens where both the Click result and the PIS designation are Positive; FN = the number of specimens where the Click result is Negative and the PIS designation is Positive; Sensitivity = 100 \* TP / (TP + FN) The specificity of the Click device is defined as follows: TN = the number of specimens where both the Click result and the PIS designation are Negative; FP = the number of specimens where the Click result is Positive and the PIS designation is Negative; Specificity = 100 \* TN / (TN + FP)
