Eligibility Criteria
Inclusion Criteria:
- Women aged 18 years and above
- Confirmed cervical infection with HPV types 16 and/or 18 at screening
- Cervical tissue specimen/slides provided to Study Pathology Adjudication Committee for
diagnosis scheduled to be collected within 10 weeks prior to anticipated date of first
dose of study drug
- Confirmed histologic evidence of cervical HSIL at screening
- Must be judged by Investigator to be an appropriate candidate for the
protocol-specified procedure required at Week 36
- With respect to their reproductive capacity must be post-menopausal or surgically
sterile or willing to use a contraceptive method with failure rate of less than 1% per
year when used consistently and correctly from screening until Week 36
- Normal screening electrocardiogram (ECG)
Exclusion Criteria:
- Microscopic or gross evidence of adenocarcinoma-in-situ (AIS), high grade vulvar,
vaginal, or anal intraepithelial neoplasia or invasive cancer in any histopathologic
specimen at screening
- Cervical lesion(s) that cannot be fully visualized on colposcopy
- History of endocervical curettage (ECC) which showed cervical HSIL indeterminate, or
insufficient for diagnosis
- Treatment for cervical HSIL within 4 weeks prior to screening
- Pregnant, breastfeeding or considering becoming pregnant during the study
- History of previous therapeutic HPV vaccination
- Immunosuppression as a result of underlying illness or treatment
- Receipt of any non-study, non-live vaccine within 2 weeks of Day 0
- Receipt of any non-study, live vaccine within 4 weeks of Day 0
- Current or history of clinically significant, medically unstable disease or condition
which, in the judgment of the investigator, would jeopardize the safety of the
participant, interfere with study assessments or endpoint evaluation, or otherwise
impact the validity of the study results
- Presence of acute or chronic bleeding or clotting disorder that would contraindicate
IM injections, or use of blood thinners within 2 weeks of Day 0
- Participation in an interventional study with an investigational compound or device
within 30 days of signing informed consent
- Less than two acceptable sites available for IM injection

Primary Outcome Measures
Measure: | Percentage of Participants with No Evidence of Cervical HSIL on Histology and No Evidence of HPV-16 and/or HPV-18 in Cervical Samples at Week 36 |
Time Frame: | At Week 36 |
Safety Issue: | |
Description: | Participants will be evaluated for evidence of cervical HSIL on histology as well as evidence of HPV-16 and/or HPV-18 in cervical samples by type-specific HPV testing at the Week 36 visit. |
Secondary Outcome Measures
Measure: | Safety: Number of Participants with Any Adverse Events (AEs) and Serious Adverse Events (SAEs) Following Investigational Treatment and for the Duration of the Study |
Time Frame: | From baseline to Week 40 |
Safety Issue: | |
Description: | An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. An SAE is any experience that suggested a significant hazard, contraindication, side effect, or precaution, and fulfilled any of the following criteria: fatal (resulted in death), life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was medically significant or required intervention to prevent any of the other outcomes listed here. |
