Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate the efficacy, immunogenicity and safety of 9-valent human papillomavirus (9vHPV; V503) vaccine in Chinese women 20 to 45 years of age. The primary hypotheses are: 9vHPV vaccine reduces the incidence of HPV 31-, 33-, 45-, 52-, and 58-related 12-month persistent infection at least 1 month post Dose 3, compared with quadrivalent HPV (qHPV) vaccine in women 20 to 45 years of age who are seronegative at Day 1 and polymerase chain reaction (PCR) negative Day 1 through Month 7 to the relevant HPV type; and 9vHPV vaccine induces non-inferior competitive luminex immunoassay (cLIA) geometric mean titers (GMTs) for each of HPV 6, 11, 16, and 18 one month post Dose 3, compared with qHPV vaccine in women 20 to 45 years of age who are seronegative at Day 1 and PCR negative Day 1 through Month 7 to the relevant HPV type.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study has two stages with the Stage I expected from Day 1 through Month 30, and the Stage II expected post-Month 30 to Month 90. The Stage I study is a case-driven study which aims to accrue at least 20 cases of HPV 31/33/45/52/58-related 12-month persistent infection and at least 39 cases of HPV 31/33/45/52/58-related 6-month persistent infection by completion of Month 30 visit. The Stage II study is a case-driven study which aims to accrue at least 12 cases of HPV 31/33/45/52/58-related cervical intraepithelial neoplasia grade 2 or 3 (CIN 2/3), cervical adenocarcinoma in situ (AIS), and cervical cancer observed in both Stage I and Stage II, by completion of Month 90 visit.

* Does not have an intact cervix uteri or has more than one cervix uteri
* Is pregnant
* Known allergy to any vaccine component, including aluminum, yeast, or Benzonase™ (nuclease, Nycomed™ \[used to remove residual nucleic acids from this and other vaccines\])
* History of severe allergic reaction (e.g., swelling of the mouth and throat, difficulty breathing, hypotension or shock) that required medical intervention
* Has thrombocytopenia or any coagulation disorder that would contraindicate intramuscular injections
* Currently immunocompromised or has been diagnosed as having a congenital or acquired immunodeficiency, human immunodeficiency virus (HIV) infection, lymphoma, leukemia, systemic lupus erythematosus (SLE), rheumatoid arthritis, juvenile rheumatoid arthritis (JRA), inflammatory bowel disease, or other autoimmune condition
* Has had a splenectomy
* Is expecting to donate eggs during Day 1 through Month 7 of the study
* Plans to receive during Day 1 through Month 7 of the study, is receiving or has received within 12 months prior to enrollment the following immunosuppressive therapies: radiation therapy, cyclophosphamide, azathioprine, methotrexate, any chemotherapy, cyclosporin, leflunomide (Arava™), tumor necrosis factor (TNF)-α antagonists, monocolonal antibody therapies (including rituximab \[Rituxan™\]), intravenous gamma globulin (IVIG), antilymphocyte sera, or other therapy known to interfere with the immune response. With regard to systemic corticosteroids, a participant will be excluded if she is currently receiving steroid therapy, has recently (defined as within 2 weeks of enrollment) received such therapy, or has received 2 or more courses of high dose corticosteroids (orally or parenterally) lasting at least 1 week within 12 months prior to enrollment. Participants using inhaled, nasal, or topical corticosteroids are considered eligible for the study.
