Immunogenicity of GlaxoSmithKline Biological's Human Papillomavirus (HPV) Vaccine (580299) Versus Merck's Gardasil® in Healthy Females 18-45 Years of Age

Titers are displayed as Geometric Mean Titers (GMTs). The titer is the serum dilution giving a 50 percent reduction of the signal compared to a control without serum.

Titers are given as Geometric Mean Titers (GMTs). Titer is the serum dilution giving a 50 percent reduction of the signal compared to a control without serum. Data for Month 7 on subjects aged 18 to 26 years are given in the outcome above as a primary outcome measure.

Other oncogenic HPV types include HPV-31 and HPV-45. The titer value (=serum dilution giving a 50 percent reduction of the signal compared to a control without serum) used as the cut-off for seroconversion was 40 for both other oncogenic types HPV-31 and HPV-45.

Other Oncogenic Types include HPV-31 and HPV-45. Titers were measured by neutralization assay and are given as Geometric Mean Titers (GMTs). The titer is the serum dilution giving a 50 percent reduction of the signal compared to a control without serum

The titer value (=serum dilution giving a 50 percent reduction of the signal compared to a control without serum) used as the cut-off for seroconversion was 40 for both HPV-16 and HPV-18.

Cut-off values assessed were greater than or equal to 8 ELISA units per milliliter (EL.U/mL) for HPV-16 and greater than or equal to 7 EL.U/mL for HPV-18.

Titers are given as Geometric Mean Titers (GMTs) expressed as Enzyme-linked Immunosorbent Assay Units Per Milliliter (EL.U/mL).

Other oncogenic types include HPV-31 and HPV-45. Cut-off values assessed were greater than or equal 59 EL.U/mL in the sera of subjects seronegative before vaccination.

Other oncogenic types include HPV-31 and HPV-45. Titers are given as Geometric Mean Titers (GMTs) expressed as Enzyme-linked Immunosorbent Assay Units Per Milliliter (EL.U/mL).

Number of cells were expressed as geometric mean, minimum and maximum values of specific CD4 cells producing at least 2 cytokines (CD40 Ligand, Interleukin-2, Tumor Necrosis Factor Alpha or Interferon-gamma) per million of CD4 T-cells.

Data were expressed as geometric mean, minimum and maximum values of specific CD8 cells producing at least 2 cytokines (CD40 Ligand, Interleukin-2, Tumor Necrosis Factor Alpha or Interferon-gamma) per million of CD8 T-cells. Analyses for further time points were not performed, as there was no response at these time points.

HPV-16 and HPV-18 Specific Memory B Cells were measured by Enzyme-linked immunosorbent spot (ELISPOT) assay and expressed as geometric mean, minimum and maximum values of specific B-cells per million of cells.

Titers are given as Geometric Mean Titers (GMTs) expressed as Enzyme-linked Immunosorbent Assay Units Per Milliliter (EL.U/mL).

Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimeters (mm) of injection site. All solicited local symptoms were assessed as related to study vaccination.

Assessed solicited general symptoms were arthralgia, fatigue, fever \[defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)\], gastrointestinal, headache, myalgia, rash and urticaria. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever \> 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.

Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms.Grade 3 AE = AE that prevented normal activity. Related AE = AE assessed by the investigator as causally related to the study vaccination.

NOCDs include autoimmune disorders, asthma, type I diabetes, allergies. MSCs include AEs prompting emergency room or physician visits that are not related to common diseases or routine visits for physical examination or vaccination, or serious adverse events (SAEs) that are not related to common diseases. Common diseases include upper respiratory infections, sinusitis, pharyngitis, gastroenteritis, urinary tract infections, cervico-vaginal yeast infections, menstrual cycle abnormalities and injury.

SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject. Related SAE = SAE assessed by the investigator as causally related to the study vaccination. Intensity of SAEs was not assessed.
