Purpose
Bacterial meningitis infection is common in youth 2 to 24 years of age in the United States. This disease can be treated by antibiotics, but mortality rates associated with meningitis of up to 53% have been estimated. Vaccination against meningitis may be effective in preventing this disease, especially for HIV-infected youth who have weakened immune systems. The purpose of this study is to determine the safety of and immune response to a preventive meningitis vaccine in HIV-infected youth.

Experimental: 1
Participants aged 11 to 24 with a CD4 percentage of or greater than 15%
|
Biological: Quadrivalent meningococcal conjugate vaccine (MCV4)
MCV4 vaccine (4 µg each of meningococcal A, C, Y, and W-135 polysaccharides conjugated to approximately 48 µg of diphtheria toxoid protein carrier ) will be given by injection intramuscularly at least once and no more than two times for each participant, depending on adverse reactions.
Biological: Quadrivalent meningococcal conjugate vaccine (MCV4) booster
MCV4 booster vaccine (4 µg each of meningococcal A, C, Y, and W-135 polysaccharides conjugated to approximately 48 µg of diphtheria toxoid protein carrier) will be given by injection intramuscularly at 3.5 years post initial vaccination

In the United States, youth 2 to 24 years of age are at high risk for bacterial meningitis infection. Despite antibiotic treatment, the mortality rate for meningitis and sepsis can reach as high as 53% caused by Neisseria meningitidis. This rate could be higher in immunocompromised individuals, such as those infected with HIV. To prevent infection, vaccination against meningitis is recommended by the CDC at ages 11, 15, and 18. The quadrivalent meningococcal conjugate vaccine (MCV4) is a vaccine that has been observed to elicit an appropriate immune response to N. meningitidis and was approved by the FDA in January 2005. However, to date, no studies have been done to determine the safety and immunogenicity of this vaccine in HIV-infected individuals. The purpose of this study is to determine the safety and immunogenicity of MCV4 in HIV-infected youth 2 to 24 years of age.
This study will last 72 weeks. Participants in this study will be stratified according to CD4 percentage (CD4%) and age. Participants aged 11 to 24 with a CD4% of 15% or higher will be a part of Group 1. Group 1 will include two cohorts. Cohort 1 will consist of youth with a CD4% between 15% and 24%. Cohort 2 will consist of youth with a CD4% of 25% or higher. Participants aged 11 to 24 with a CD4% of lower than 15% will join Group 2. Participants aged 2 to 10 with a CD4% of 25% or higher will join Group 3.
At study entry, all study participants will receive one injection of MCV4. Participants will be observed for 30 minutes post-injection to monitor for adverse events. A clinic visit is required 24 hours post-injection if the participant reports adverse events. Participants in Group 1 who did not experience any adverse events after the first injection will be randomly assigned to Group 1A or Group 1B at Week 24. Group 1B, Group 2, and Group 3 participants who had no adverse events after the first injection will receive a second injection of MCV4 at Week 24.
There will be five study visits; they will occur at study entry and at Weeks 4, 24, 28, and 72. At these visits, a physical exam, assessment of HIV-related symptoms, and blood collection will occur. In addition, study participants will be contacted by telephone at Days 3 and 7 and Weeks 1, 6, and 25 after the first vaccination. Participants in Groups 1B and 2 who receive a second injection will be contacted by telephone at Weeks 30 and 48.
As of November 2010, due to data from this study (P1065) and recommendations from the Advisory Committee for Immunization Practices (ACIP) of the Center for Disease Control (CDC), eligible participants in Groups 1 (1A and 1B) and 3 of P1065 will receive a booster dose of MCV4 at approximately 3.5 years (+/- 6 months) after the initial MCV4 vaccination. Participants will then be observed for 30 minutes post-injection to monitor for adverse events. Participants will also be observed at Week 1 for vaccine adverse reactions.
This portion of the study (Step 3) will last an additional 24 weeks. There will be 4 study visits; they will occur at entry, at Days 7-8, and at Weeks 4 and 24. At these visits, a physical exam, assessment of HIV-related symptoms, and blood collection will occur. The purpose of this follow-up study is to determine the safety and immunogenicity of a MCV4 booster dose in HIV-infected participants who have previously received one or two MCV4 vaccinations on this study.
