Evaluation of the Immunogenicity and Safety of GlaxoSmithKline Biologicals' HPV Vaccine in Young Males.

Seroconversion was defined as the appearance of anti-HPV-16 and/or anti-HPV-18 antibodies [anti-HPV-16 titers greater than or equal to (≥) 8 enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL) and anti-HPV-18 titres ≥7 EL.U/mL] in the serum of subjects seronegative before vaccination.

Titers were presented as geometric mean titers (GMT).

Seroconversion was defined as the appearance of anti-HPV-16 and/or anti-HPV-18 antibodies (anti-HPV-16 titres ≥ 8 EL.U/mL and anti-HPV-18 titres ≥ 7 EL.U/mL) in the serum of subjects seronegative before vaccination.

Titers were presented as GMTs.

Solicited local symptoms assessed were pain, redness and swelling. Any = any solicited local symptom irrespective of intensity grade; Grade 3 pain = pain that prevented normal activity; Grade 3 redness/swelling = redness/swelling spreading beyond (>) 50 mm.

Solicited general symptoms assessed were arthralgia, fatigue, fever (defined as axillary temperature ≥37.5 °C), gastrointestinal, headache, myalgia, rash and urticaria. Any = any solicited general symptom irrespective of intensity grade or relationship to vaccination; Grade 3 = symptom that prevented normal activity; Grade 3 fever = temperature > 39.0 °C; Related = symptoms considered by the investigator to have a causal relationship to vaccination.

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and 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. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination.

NOCDs include asthma, Chron's disease, dermatitis atopic. 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 and injury.

Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

The occurence of clinically relevant abnormalities was assessed in the following biochemical and haematological parameters: alanine aminotransferase [ALT], basophils [BAS], creatinine [CREA], eosinophils [EOS] and hematocrit [Hem]. Levels of haematological/biochemical parameters assessed in terms of normal, below and above laboratory values were - normal, below, above and missing.

The occurence of clinically relevant abnormalities was assessed in the following biochemical and haematological parameters: lymphocytes [LYM], monocytes [MON], neutrophils [NEU], platelets [PLA], red blood cells [RBC] and white blood cells [WBC]. Levels of haematological/biochemical parameters assessed in terms of normal, below and above laboratory values were - normal, below, above and missing.
