Confirmed histopathological evidence of cervical HSIL (CIN3) at the screening period or within 1 month prior to screening; 3. Confirmed cervical HPV-16 positive by HPV test during the screening period or within 1 month prior to screening, without other high-risk HPV types detected; 4. Complete visibility of both the squamocolumnar junction (SCJ Types 1/2) and the upper margin of acetate-white epithelium or suspected HSIL lesions under colposcopy examine during the screening period or within 1 month prior to screening; 5. No evidence of precancerous lesions or malignancy by endocervical curettage (ECC) ; 6. The biopsy sampling of cervical lesions are performed; 7. Visible residual cervical lesions after screening biopsy; 8.
