Complementary Testing to Evaluate Immunogenicity of Human Papillomavirus (HPV) Vaccine (580299) in Healthy Female Subjects Aged >/= 26 Years
Complementary Testing to Further Evaluate the Immunogenicity of a GSK Biologicals' HPV Vaccine (580299) in Healthy Female Subjects Aged Over 26 Years Enrolled in Study 104820.
Infection with human papillomavirus (HPV) has been clearly established as the central cause of cervical cancer. Indeed, certain oncogenic types of HPV can infect the cervix (part of the uterus or womb). This infection may go away by itself, but if it does not go away (this is called persistent infection), it can lead in women over a long period of time to cancer of the cervix. This study will supplement an ongoing study evaluating the safety, efficacy and immunogenicity of the vaccine in women aged 26 years and above. This study will therefore assess additional immunogenicity parameters of the vaccine in women from selected investigative sites.
The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Number of Cytokine-positive CD4/CD8 Cells Per Million in Tests Producing at Least 2 Different Cytokines
Time Frame: At Month 12 and Month 18 after first vaccination
|
The geometric mean and 95% confidence interval of the number of Human Papilloma Virus type 16 (HPV-16) and HPV-18 specific CD4 and CD8 cells producing at least 2 different cytokines is reported per million of CD4 or CD8 T-cells, respectively.
|
At Month 12 and Month 18 after first vaccination
|
|
Number of B-cells Per Million Showing a Specific Memory Response for HPV-16 and HPV-18
Time Frame: At Month 12 and Month 18 after first vaccination
|
The geometric mean and 95% confidence interval of the number of HPV-16 and HPV-18 specific memory B-cells is reported per million of B-cells. An arbitrary value of 0 was given for subjects with antibody concentration below the limit of quantification. |
At Month 12 and Month 18 after first vaccination
|
|
Number of Subjects With Anti-HPV-16 and Anti-HPV-18 Antibody Concentrations Above Pre-defined Cut-off Values
Time Frame: At Month 12 and Month 18 after first vaccination
|
Cut-off values assessed include 8 enzyme-linked immunosorbent assay units Per Milliliter (EL.U/mL)for anti-HPV-16 antibodies and 7 EL.U/mL for anti-HPV-18 antibodies.
|
At Month 12 and Month 18 after first vaccination
|
|
Titers of Anti-HPV-16 and Anti-HPV-18 Antibodies
Time Frame: At Month 12 and Month 18 after first vaccination
|
Titers are presented as Geometric Mean Titers (GMTs).
|
At Month 12 and Month 18 after first vaccination
|
|
Titers of Anti-human Papilloma Virus 16 (Anti-HPV-16) Immunoglobulin G (IgG) Antibodies
Time Frame: At Month 12 and Month 18 after first vaccination
|
Titers given as Geometric Mean Titers (GMTs).
An arbitrary value of 0 was given for subjects with antibody concentration below the limit of quantification.
|
At Month 12 and Month 18 after first vaccination
|
|
Correlation of Anti-HPV-16 and Anti-HPV-18 Antibodies in Serum and in Cervical Secretion (CVS) Samples
Time Frame: At Month 12 and Month 18 after first vaccination
|
Pearson coefficients of correlation between serum and CVS for anti-HPV-16 and anti-HPV-18 titers standardized for total IgG were calculated.
|
At Month 12 and Month 18 after first vaccination
