E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Prevention of HPV types 6, 11, 16 and 18 related cervical cancer, vulvar, vaginal pre-cancers, low-grade, pre-cancerous lesions, and genital warts in Chinese female subjects aged 9 to 45 years and male subjects aged 9 to 15 years. |

Prevention of certain cancers related to Human Papilloma Virus (HPV) |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Cancer [C04] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
(1) To evaluate the vaccine-induced serum anti-HPV 6, anti-HPV 11, anti-HPV 16, and anti-HPV 18 antibody titers following administration of a 3-dose regimen of GARDASIL™ compared with placebo. (2) To demonstrate that a 3-dose regimen of GARDASIL™ is generally well tolerated in subjects aged 9 to 45 years. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the vaccine-induced seroconversion rate of anti-HPV 6, anti-HPV 11, anti-HPV 16, and anti-HPV 18 following administration of a 3-dose regimen of GARDASIL™ in subjects who are seronegative to respective HPV types prior to vaccination. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Key Inclusion criteria: Healthy Chinese female subjects aged 9-45 years old and male aged 9-15 years old upon receipt of the first study vaccination; not pregnant now for post-pubertal female subjects. |
|
E.4 | Principal exclusion criteria |
Key Exclusion criteria: subjects must have temperature <37.1 degrees C within 24 hours prior to the first injection; without a history of severe allergic reaction or allergic reaction to any vaccine component; no history of immune globulin or blood-derived products within 6 months prior to first injection or plan to receive any through the completion of the study; negative history of splenectomy, immune disorder or receiving immunosuppressives; no history of immunocompromised or HIV infection; no history of thrombocytopenia or any coagulation disorder; no history of abnormal Pap test or biopsy showing CIN or worse; ≤ 4 lifetime sexual partners. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
(1) The primary immunogenicity endpoint of interest are the GMTs for each HPV vaccine type, by 1 month Postdose 3. (2) The primary safety variables of key interest are serious adverse experiences, systemic adverse experiences prompted for on the vaccine report card (VRC) occurring within 14 days after each vaccination, and injection-site complaints prompted for on the VRC, such as temperature, redness, swelling, and pain/tenderness/soreness occurring Day 1 through Day 5 after each vaccination. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
(1) 1 month Postdose 3; (2) adverse experiences occurring within 14 days after each vaccination. |
|
E.5.2 | Secondary end point(s) |
The secondary endpoints are the percentages of vaccine recipients who seroconvert to each of HPV 6, 11, 16, 18 by 1 month Postdose 3. |
