The CINtec PLUS Cytology test includes a ready-to-use cocktail of primary antibodies which contains a mouse monoclonal antibody directed against human p16INK4a (p16) protein (clone E6H4), and a recombinant rabbit monoclonal antibody directed against human Ki-67 protein (clone 274-11AC3V1) for use on the BenchMark ULTRA instrument with 3,3ʹ-diaminobenzidine tetrahydrochloride (DAB) and Fast Red detection systems. The CINtec PLUS Cytology test is indicated: To be used in women 25 – 65 years old with 12 Other High Risk (HR) HPV positive test results using cobas® HPV for use on the cobas® 6800/8800 Systems (cobas® HPV) or the cobas® 4800 HPV Test in primary HPV screening, to determine the need for referral to colposcopy. To be used in women 25 – 65 years old with HPV16/18 positive test results using cobas® HPV or the cobas® 4800 HPV Test in primary HPV screening where the CINtec PLUS Cytology test results will be used in conjunction with the physician’s assessment of patient screening history, other risk factors, and professional guidelines to guide patient management. To be used in women 30 – 65 years old with NILM (Negative for Intraepithelial Lesion or Malignancy) and 12 Other HR HPV positive test results using cobas® HPV or the cobas® 4800 HPV Test in adjunctive cervical cytology and HR HPV screening, to determine the need for referral to colposcopy.

Results from the CINtec PLUS Cytology test should be interpreted by a qualified pathologist. en The CINtec PLUS Cytology test contains a set of reagents for the simultaneous immunocytochemical detection of the p16INK4a and Ki-67 proteins in cytological specimens obtained from the uterine cervix. The proteins are detected using a ready-to-use cocktail of primary monoclonal antibodies which contains a monoclonal mouse antibody directed against human p16INK4a protein (clone E6H4) and a primary recombinant rabbit antibody directed against human Ki-67 protein (clone 274-11AC3V1). Following cell conditioning, inhibition of endogenous peroxidase activity and incubation with the primary antibody cocktail, the assay uses two ready-to-use detection systems optimized for use on cervical cytology specimens collected in PreservCyt Solution: a goat anti-mouse secondary antibody covalently attached to HQ haptens (proprietary hapten) and an anti-HQ hapten, horseradish peroxidase (HRP)-conjugated tertiary antibody optimized for the detection of the monoclonal mouse antibody clone E6H4, as shown in Figure 2. a goat anti-rabbit secondary antibody covalently attached to NP haptens (proprietary hapten) and an anti-NP hapten, alkaline-phosphatase (AP)-conjugated tertiary antibody optimized for the detection of the rabbit recombinant antibody clone 274-11AC3V1, as shown in Figure 3. The chromogenic reactions are based on the HRP-mediated conversion of 3,3′-diaminobenzidine tetrahydrochloride (DAB) and the AP-mediated conversion of Fast Red with Naphthol Phosphate resulting in a brown precipitate at the p16INK4a antigen site and a red precipitate at the Ki-67 antigen site, respectively. After automated counterstaining and bluing, a two-step mounting procedure is followed. First, the slide is mounted using an aqueous mounting medium. Subsequently, the slide is coverslipped using a permanent mounting medium. The staining results are evaluated by light microscopy. Figure 2. Detection of human p16INK4a protein. Figure 3.

CINtec PLUS Cytology, a biomarker-based triage test to identify transforming HPV infection

Not every HPV-positive woman will develop cervical cancer, so triage can determine who is most at risk and will benefit from more immediate follow-up, and who is at low risk and can be given more time to clear the infection on her own. CINtec PLUS is a triage cytology test that helps stratify disease risk immediately, giving clinicians confidence when selecting the appropriate management for women at every level of risk.

Detect changes at the cellular level:

The CINtec PLUS Cytology test is the only FDA approved triage test that uses dual biomarker technology to simultaneously detect p16 and Ki-67 in women with HPV-positive results.

The co-expression of these two biomarkers within the same cell is a strong indicator that an HPV infection is undergoing oncogenic transformation.

The IMPACT Trial:
The landmark registational cervical cancer portfolio trial

Included cobas^® HPV test, CINtec PLUS Cytology test, and CINtec^® Histology
Multicenter, prospective trial enrolling ~35,000 women at 32 collection sites across the US
Representative of routine cervical cancer screening population in the US:
- Ages 25-65
- Non-vaccinated and vaccinated
- Diverse races and ethnicities
More than 5,000 HPV-positive subjects
More than 530 ≥CIN2 disease cases

Risk of disease in Pap normal/HPV+ women (≥CIN2, age 30-65)

CINtec PLUS Cytology provides further risk stratification in 12 other HPV+ women

The addition of the CINtec PLUS Cytology test can provide a more accurate quantification of a woman's risk for high grade disease.

Increased testing sensitivity

When added as a triage to discrepant co-testing results, CINtec PLUS Cytology identified 7 our of 10 women as having cells undergoing oncogenic transformation allowing identification of disease earlier in their screening process.

Integrates with automated testing procedures to improve efficiency

CINtec PLUS Cytology is performed from the same ThinPrep sample as HPV and Pap tests, and run on the BenchMark ULTRA. The BenchMark ULTRA system is a fully automated immunohistochemistry and in situ hybridization slide staining system, offering multiple features designed to provide diagnostic confidence to histopathology laboratories worldwide. With 30 independent slide drawers, the system gives histotechnologists continuous random access and supports single-piece workflow, which numerous studies have shown improves laboratory operational efficiency.
