A Study of RO5217790 in Participants With High Grade Cervical Intraepithelial Neoplasia (CIN) Associated With High Risk Human Papillomavirus (HR-HPV) Infection

Inclusion Criteria: * Have a diagnosis within 2 months prior to the first dose of RO5217790 of CIN 2/3 confirmed by colposcopy-directed punch biopsy; patients must have at least 1 quadrant of residual CIN2/3 disease remaining after biopsy. Entry to the trial will be allowed based on the local assessment of this criterion; however, CIN 2/3 diagnosis will have to be confirmed by the central pathologist for the purposes of analyzing the study * Have satisfactory colposcopy, i.e. the entire acetowhite or disease area as well as the entire squamocolumnar junction visualized by colposcopy * Have detection at screening of a single or multiple HR-HPV infection by analysis of liquid based cytology (LBC) material on the Roche Linear Array assay consistent with any of the trial strata as specified in study protocol Exclusion Criteria: * Have colposcopically visible CIN2/3 disease extending over more than 2 quadrants * Have any anatomical condition of the cervix, including that resulting from previous cervical surgery, congenital malformation or other condition, that would interfere with a complete evaluation of the transformation zone and surveillance of CIN. If an endocervical curettage (ECC) is performed, and the endocervical curettings reveal CIN, patients are eligible as long as the endocervical lesion is directly extending from the primary lesion and is colposcopically visible in its entirety * Have vulvar (VIN) or vaginal (VAIN) intraepithelial neoplasia * Have atypical endomet…
