ClinicalTrials.gov Identifier:	NCT00187902

Purpose

Julius Schachter, PhD, from the Department of Laboratory Medicine at UCSF, and Jeffrey Klausner, MD, from the Department of Public Health, are conducting a study to evaluate a type of test (nucleic acid amplification test) for the detection of two sexually transmitted diseases, Chlamydia trachomatis and Neisseria gonorrhoeae, in men who have sex with men (MSM), using urine samples and swabs taken from the throat (pharynx), tip of penis (glans), and rectum. The use of nucleic acid amplification tests on these swabs is experimental, which means that the use of the tests for this purpose have not been approved by the Food & Drug Administration.

Primary Outcome Measures:

Positive nucleic acid amplification result for Chlamydia trachomatis or Neisseria gonorrhoeae. [ Time Frame: At enrollment/screening ] [ Designated as safety issue: No ]

Biospecimen Retention: Samples With DNA

Biospecimen Description:

self-collected glans swab; clinician-collected rectal and pharyngeal swabs

Estimated Enrollment:	1000
Study Start Date:	October 2005
Estimated Study Completion Date:	December 2008
Primary Completion Date:	May 2007 (Final data collection date for primary outcome measure)

Detailed Description:

For all subjects enrolled in the study, the following clinical data information will be obtained: 1) reason for exam, 2) subject's signs and symptoms and 3) clinical assessment.

For each subject enrolled in the study, three clinician-collected pharyngeal, four rectal swabs (three clinician-collected, 1 self-collected) specimens, one glans swab (self-collected) and a first catch urine specimen (approximately 25 ml) will be obtained. The collection order of the clinician collected swabs will be randomized.

Three pharyngeal swabs will be tested for: 1) CT/NG NAAT (TMA) at DPH, 2) NG culture at DPH and 3) NAATs for CT/NG (TMA, SDA) and CT culture at UCSF. Four rectal swabs will be tested for: 1) CT/NG NAAT (TMA) at DPH, 2) NG culture at DPH and 3) NAATs for CT/NG on Clinician- and self-collected rectal swab (TMA, SDA) and CT culture at UCSF. Self-collected glans swab and the FCU will be tested by NAATs for CT/NG (TMA, SDA) at UCSF. All NAAT specimens collected in a universal NAAT transport medium. After specimen processing, samples will be frozen at -70 C for discrepant analysis.

Eligibility

Genders Eligible for Study:	Male
Accepts Healthy Volunteers:	Yes
Sampling Method:	Non-Probability Sample

Study Population

Men who have sex with men (MSM) voluntarily presenting at the City STD clinic.

Criteria

Inclusion Criteria:

A subject must be a man who has sex with men (MSM). Subjects must provide verbal consent, must be able to submit all required specimens and must not have urinated within 1 hr prior to providing a study urine specimen.

Exclusion Criteria:

Subjects are excluded if they do not have sex with men, refuse to give verbal consent, are unable to provide all required specimens and minimum specimen volume, have been on antibiotic therapy within the last 21 days, have urinated within 1 hr prior to submitting study specimens, and have already been evaluated as part of this trial. Subjects will be excluded if specimens are mishandled or inappropriately stored.
