研究概览
简要总结
The purpose of the study was to evaluate the immunogenicity and describe the safety of Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine compared to the licensed vaccine MENVEO® in adolescents 10 to 17 years of age in the United States (US). This study also evaluated the immunogenicity and safety of MenACYW Conjugate vaccine when given alone compared to when given concomitantly with tetanus, diphtheria, acellular pertussis (Tdap) vaccine and human papilloma virus (HPV) vaccine.
Primary objective:
- To evaluate the antibody responses to the antigens present in MenACYW Conjugate vaccine when MenACYW Conjugate vaccine was given alone compared to those when MENVEO vaccine was given alone.
Secondary objective:
- To evaluate the antibody responses to the antigens present in MenACYW Conjugate vaccine, when MenACYW Conjugate vaccine was given concomitantly with Tdap and HPV vaccines, compared to those when it was given alone.
- To evaluate the antibody responses to the antigens present in Tdap vaccine, when Tdap vaccine was given concomitantly with MenACYW Conjugate vaccine and HPV vaccine, compared to those when Tdap vaccine was given with HPV vaccine only.
- To evaluate the antibody responses to the antigens present in HPV vaccine after the 3-dose series, when the first dose of HPV vaccine is given concomitantly with MenACYW Conjugate vaccine and Tdap vaccine, compared to those when the first dose of HPV vaccine is given with Tdap vaccine only.
Observational objective:
- To describe the safety profile of MenACYW Conjugate vaccine, compared to that of the licensed vaccine MENVEO®, and when MenACYW Conjugate vaccine was given with Tdap and HPV vaccines.
详细描述
Healthy adolescents were randomized and received a single dose of their assigned vaccines. They were assessed for immunogenicity at baseline (pre-vaccination) and at 30 days post-vaccination. Safety information were collected post-vaccination and throughout the entire study.

入选标准
- •Aged 10 to 17 years on the day of inclusion.
- •Informed consent form was signed and dated by the parent(s) or another legally acceptable representative.
- •Assent form was signed and dated by the participant.
- •Participant and parent legally acceptable representative were able to attend all scheduled visits and comply with all trial procedures.
排除标准
- •Participant was pregnant, or lactating, or of childbearing potential (to be considered of non-childbearing potential, a female must be pre-menarche, surgically sterile, or using an effective method of contraception or abstinence from at least 4 weeks prior to the first vaccination and until at least 4 weeks after the last vaccination).
- •Participation in the 4 weeks preceding the first trial vaccination(s) or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure.
- •Receipt of any vaccine in the 4 weeks preceding the first trial vaccination(s) or planned receipt of any vaccine in the 4 weeks prior to or following any trial vaccination except for influenza vaccination, which may be received at least 2 weeks before or after any study vaccines. This exception included monovalent influenza vaccines and multivalent influenza vaccines.
- •Previous vaccination against meningococcal disease with either the trial vaccine or any mono- or polyvalent polysaccharide or conjugate meningococcal vaccine containing A, C, W, or Y antigens.
- •History of vaccination with any tetanus, diphtheria, or pertussis vaccine within the previous 4 years.
- •Previous human papilloma virus (HPV) vaccination.
- •Receipt of immune globulins, blood or blood-derived products in the past 3 months.
- •Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months).
- •History of meningococcal infection, confirmed either clinically, serologically, or microbiologically.
- •At high risk for meningococcal infection during the trial (i.e., participants with persistent complement deficiency, with anatomic or functional asplenia, or participants travelling to countries with high endemic or epidemic disease).
- •Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccines used in the trial or to a vaccine containing any of the same substances, including encephalopathy (e.g., coma, decreased level of consciousness, prolonged seizures) within 7 days of administration of a previous pertussis antigen-containing vaccine.
- •Personal history of Guillain-Barré syndrome.
- •Personal history of an Arthus-like reaction after vaccination with a tetanus toxoid-containing vaccine within at least 10 years of the proposed study vaccination.
- •Verbal report of thrombocytopenia, contraindicating intramuscular vaccination.
- •Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination.
- •Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily.
- •Current alcohol abuse or drug addiction.
- •Chronic illness (e.g., human immunodeficiency virus [HIV] hepatitis B, hepatitis C) that, in the opinion of the investigator, was at a stage where it might interfere with trial conduct or completion.
- •Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature >= 100.4 degree fahrenheit [°F]). A prospective participant was not included in the study until the condition had resolved or the febrile event had subsided.
- •Receipt of oral or injectable antibiotic therapy within 72 hours prior to the first blood draw.
- •Identified as an Investigator or employee of the Investigator or study center with direct involvement in the proposed study, or identified as an immediate family member (i.e., natural or adopted child) of the Investigator or employee with direct involvement in the proposed study.
结局指标
主要结局
Percentage of Participants Achieving Vaccine Seroresponse Measured by Serum Bactericidal Assay Using Human Complement (hSBA) Against Meningococcal Serogroups A, C, Y, and W Following Vaccination With Either MenACYW Conjugate Vaccine or MENVEO® Vaccine
时间窗: Day 30 (post-vaccination)
Antibody titers against meningococcal serogroups A, C, Y, and W measured by hSBA. The hSBA vaccine seroresponse for serogroups A, C, Y, and W was defined as post-vaccination hSBA titers greater than or equal to (\>=) 1:8 for participants with pre-vaccination hSBA titers less than (\<) 1:8 or at least a 4-fold increase in hSBA titers from pre- to post vaccination for participants with pre-vaccination hSBA titers \>= 1:8. Data for this outcome measure was not planned to be collected and analyzed for Group 4:Tdap+HPV.
