About this study

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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

An observational study of Sexually Transmitted Diseases and Chlamydia, run by University of California, San Francisco at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Apr 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Positive nucleic acid amplification result for Chlamydia trachomatis or Neisseria gonorrhoeae. (time frame: At enrollment/screening). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00187902, which also lists 10 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Apr 2011.
