A prospective multi-center clinical study was conducted to evaluate the use of the PreservCyt transport medium (a component of the ThinPrep 2000 System) as an alternative medium for gynecological specimens for the detection of N. gonorrhoeae by the APTIMA GC Assay. One thousand six hundred forty-six (1,646) symptomatic and asymptomatic female subjects attending OB/GYN, family planning, public health, women's, and STD clinics were evaluated in the clinical study. Of the 1,646 evaluable subjects, 1,287 were asymptomatic subjects and 359 were symptomatic subjects. Subjects were enrolled from sites with GC prevalence that ranged from 0.0% to 5.0%. Two specimens were collected from each eligible subject: one PreservCyt liquid Pap specimen and one endocervical swab specimen. PreservCyt liquid Pap specimens were collected with the spatula/cyto-brush or a broom-like brush cervical sampling device. PreservCyt liquid Pap specimens were processed in accordance with the ThinPrep 2000 Processor Operator's Manual and APTIMA Specimen Transfer Kit package insert. After processing the PreservCyt liquid Pap specimen with the ThinPrep 2000 Processor, the specimen was transferred into the APTIMA Specimen Transfer Kit for testing with the APTIMA GC Assay. Sensitivity and specificity of the APTIMA GC Assay in PreservCyt liquid Pap specimens were calculated by comparing results to the patient infected status. The algorithm included APTIMA Combo 2 Assay and APTIMA GC Assay results in endocervical swab specimens. Both reference NAATs were required to be positive to establish an infected patient status. At least one reference NAAT was required to be negative to establish a non-infected patient status. If an equivocal result was obtained from any one of the reference NAATs, the patient infected status was categorized as inconclusive; these specimens were not included in the sensitivity and specificity calculations.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical (Analytical Laboratory) Performance Data:
Limit of Detection (Analytical Sensitivity): N. gonorrhoeae analytical sensitivity (limit of detection) was determined by directly comparing dilutions of 51 different clinical isolates in culture and in the APTIMA GC Assay. The analytical sensitivity claim for the assay is 50 cells/assay (362 cells/swab, 250 cells/mL urine, 487.5 cells/mL PreservCyt Solution liquid Pap).
Analytical Specificity: A total of 154 culture isolates (86 organisms from urogenital tract, 68 phylogenetic cross-section organisms including bacteria, fungi, yeast, parasites and viruses) were evaluated using the APTIMA GC Assay. All organisms tested produced a negative result in the APTIMA GC Assay.
Interference Studies: Interfering substances (10% blood, contraceptive jelly, spermicide, moisturizer, hemorrhoidal anesthetic, body oil, powder, anti-fungal cream, vaginal lubricants, feminine spray and leukocytes (1x10 cells/mL), 30% blood, urine analytes, protein, glucose, ketones, bilirubin, nitrate, urobilinogen, pH 4 (acidic), pH 9 (alkaline), cellular debris, vitamins, minerals, acetaminophen, aspirin and ibuprofen) were individually spiked into swab, PreservCyt liquid Pap, and/or urine specimens in the absence and presence of GC. No interference was observed with any of the tested substances. No inhibitors of amplification were observed.
Recovery: Escherichia coli, Gardnerella vaginalis, Lactobacillus acidophilus, Bacteroides ureolyticus and Staphylococcus epidermidis (1 x 106 cells/assay) were added to samples containing the rRNA equivalent of approximately 50 N. gonorrhoeae cells (250 fg). These additions did not interfere with the amplification and detection of N. gonorrhoeae rRNA using the APTIMA GC Assay.
Liquid Pap Specimen Stability Studies: Data supported recommended shipping and storage conditions for PreservCyt Solution liquid Pap samples. Spiked samples remained positive at various temperatures and time points (e.g., 2°C, 10°C, 30°C for up to 36 days; -20°C or -70°C for up to 106 days).
Within-laboratory Precision: Performed by spiking PreservCyt vials at 0.1, 0.5, and 50 CFU/reaction.

Escherichia coli, Gardnerella vaginalis, Lactobacillus acidophilus, Bacteroides ureolyticus and Staphylococcus epidermidis (1 x 10° cells/assay) were added to samples containing the rRNA equivalent of approximately 50 N. gonorrhoeae cells (250 fg). These additions did not interfere with the amplification and detection of N. gonorrhoeae rRNA using the APTIMA GC Assay.
Liquid Pap Specimen Stability Studies
Data to support the recommended shipping and storage conditions for PreservCyt Solution liquid Pap samples were generated with negative processed and unprocessed liquid Pap samples. For the unprocessed samples, four pools of PreservCyt Solution samples were tested after being stored in the Cytyc PreservCyt Solution vial. Each specimen pool was spiked with 50-100 CFU GC/assay, held at 2℃, 10℃, and 30℃, then tested at baseline and on days 5, 7, 8, 14, 18, 21, 25 and 36. All of the spiked samples were positive for GC at all times and temperatures. For the processed samples, four pools of PreservCyt Solution samples were used to determine processed specimen stability at 2℃ to 30℃. Each negative sample pool was spiked with 50-100 IFU GC/assay, then tested at baseline. Prior to processing, the PreservCyt Solution samples were stored at 30°C for seven (7) days to simulate the time lapse between sample collection, Pap processing and shipment to a microbiology testing lab. After seven days at 30℃, 1 mL aliquots of each pool were transferred to an APTIMA Specimen Transfer Tube and tested at baseline before being placed at 2℃, 10℃, and 30℃. The processed samples were then tested for 17 days stored at 30°C and 36 days stored at 2°C to 10°C. All of the spiked samples were positive for GC at all times and temperatures. Data to support longer storage conditions were generated from four pools of negative processed PreservCyt Solution samples tested at below freezing temperatures. Each pool was spiked with 50-100 IFU CT/assay, then tested at baseline. Each pool was first placed at 30°C for 14 days and then stored at -20°C or -70°C over the course of 106 days. All of the spiked samples were positive for GC at all times and temperatures.

Summary of Clinical Performance Data
A prospective multi-center clinical study was conducted to evaluate the use of the PreservCyt transport medium (a component of the ThinPrep 2000 System) as an alternative medium for gynecological specimens for the detection of N. gonorrhoeae by the APTIMA GC Assay. One thousand six hundred forty-six (1,646) symptomatic and asymptomatic female subjects attending OB/GYN, family planning, public health, women's, and STD clinics were evaluated in the clinical study. Of the 1,646 evaluable subjects, 1,287 were asymptomatic subjects and 359 were symptomatic subjects (Table 3). Subjects were enrolled from sites with GC prevalence that ranged from 0.0% to 5.0%. Two specimens were collected from each eligible subject: one PreservCyt liquid Pap specimen and one endocervical swab specimen. PreservCyt liquid Pap specimens were collected with the spatula/cyto-brush or a broom-like brush cervical sampling device. The distribution of cervical sampling devices is summarized in Table 4 by specimen collection site and overall. PreservCyt liquid Pap specimens were processed in accordance with the ThinPrep 2000 Processor Operator's Manual and APTIMA Specimen Transfer Kit package insert. After processing the PreservCyt liquid Pap specimen with the ThinPrep 2000 Processor, the specimen was transferred into the APTIMA Specimen Transfer Kit for testing with the APTIMA GC Assay. Sensitivity and specificity of the APTIMA GC Assay in PreservCyt liquid Pap specimens were calculated by comparing results to the patient infected status. The algorithm included APTIMA Combo 2 Assay and APTIMA GC Assay results in endocervical swab specimens. Both reference NAATs were required to be positive to establish an infected patient status. At least one reference NAAT was required to be negative to establish a non-infected patient status. If an equivocal result was obtained from any one of the reference NAATs, the patient infected status was categorized as inconclusive; these specimens were not included in the sensitivity and specificity calculations. Table 4 shows the sensitivities and specificities of the APTIMA GC Assay by symptom status and overall. Overall sensitivity was 92.3% (12/13). In symptomatic and asymptomatic subjects, sensitivities were 100% (7/7) and 83.3% (5/6), respectively. Overall specificity was 99.8% (1630/1633). In symptomatic and asymptomatic subjects, specificities were 99.4% (350/352) and 99.9% (1280/1281), respectively. Table 5 shows the sensitivities and specificities of the APTIMA GC Assay by specimen collection site and overall. Sensitivities ranged from 80.0% to 100%. Specificities ranged from 99.0% to 100%.

APTIMA Assay for Neisseria gonorrhoeae -- Expanded Indication: ThinPrep Specimens
Conclusions from Non-Clinical and Clinical Data
The non-clinical and clinical study results support the use of PreservCyt liquid Pap specimens collected and processed by the Cytyc ThinPrep 2000 Processor in the currently marketed GEN-PROBE APTIMA Assay for Neisseria gonorrhoeae. The currently marketed GEN-PROBE APTIMA Specimen Transfer Kit provides necessary materials and instructions to allow for the testing of PreservCyt liquid Pap specimens in the APTIMA GC Assay.
The results of the clinical study demonstrate reasonable evidence that when the APTIMA GC Assay and the APTIMA Specimen Transfer Kit are labeled as proposed, the APTIMA GC Assay continues to be safe and effective for its stated intended use.
Contraindications and Cautions
There are no contraindications or cautions.

APTIMA Assay® for Neisseria gonorrhoege
INDICATIONS FOR USE STATEMENT
510(k) Number: (if known)
GEN-PROBE APTIMA Assay® for Neisseria gonorrhoeae Device Name: Indications for Use:
The APTIMA® Assay for Neisseria gonorrhoeae is a target amplification nucleic acid probe test that utilizes target capture for the in vitro qualitative detection of ribosomal RNA (rRNA) from Neisseria gonorrhoeae (GC) to aid in the diagnosis of gonococcal urogenital disease. The assay may be used to test the following specimens from symptomatic individuals: clinician-collected endocervical, vaginal and male urethral swab specimens; and female and male urine specimens. The assay may be used to test the following specimens from asymptomatic individuals: cliniciancollected endocervical and vaginal swab specimens; and patient-collected vaginal swab specimens and female and male urine specimens. The assay is also intended for use with the testing of gynecological specimens, from both symptomatic and asymptomatic patients, collected in the PreservCyt Solution and processed with the Cytyc ThinPrep 2000 System.
4 Patient-collected vaginal swab specimens are an option for screening women when a pelvic exam is not otherwise indicated. The vaginal swab specimen collection kit is not for home use.
