Vaccines Treatment Options in Missouri

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 Meningococcal (Groups A, C, Y and W 135) Oligosaccharide Diphtheria CRM197 (MENVEO®) vaccine in children 2 to 9 years of age in the United States (US) and Puerto Rico. Primary objective: - To demonstrate the non-inferiority of the vaccine seroresponse to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine compared to that observed following the administration of a single dose of MENVEO® in children aged 2 to 9 years. Secondary objectives: * To compare the serum bactericidal assay using human complement (hSBA) antibody geometric mean titers (GMTs) of meningococcal serogroups A, C, Y, and W following the administration of MenACYW Conjugate vaccine to those observed following the administration of MENVEO® in children 2 to 9 years of age. * To evaluate the hSBA antibody GMTs of meningococcal serogroups A, C, Y, and W following the administration of MenACYW Conjugate vaccine and those observed following the administration of MENVEO® in children 2 to 5 years of age, and in children 6 to 9 years of age, respectively. * To evaluate the hSBA vaccine seroresponse to meningococcal serogroups A, C, Y, and W before and 30 days (+14 days) post-vaccination in children 2 to 5 years of age, and in children 6 to 9 years of age, respectively. Observational objective: - To describe the safety profile of MenACYW Conjugate vaccine and that of the licensed MENVEO®. Read Less

INVESTED will test the hypothesis that high dose trivalent influenza vaccine will reduce cardiopulmonary events to a greater extent than standard dose quadrivalent influenza vaccine in high-risk cardiovascular patients with a recent history of myocardial infarction or heart failure. The trial will enroll 9300 participants over one Vanguard (pilot) season and three additional influenza seasons. The primary endpoint will be a composite of all-cause mortality or cardiopulmonary hospitalization. Read Less

This study will assess the safety, tolerability and immune response of 13-valent pneumococcal conjugate vaccine (13vPnC) compared with 23-valent Pneumococcal Polysaccharide Vaccine (23vPS). Although the study started with only 1 population, amendments to the original protocol will now reflect three participant populations. Three age cohorts will be enrolled. The first cohort (age 60-64) will be blinded. Cohort 2 (age 50-59) and cohort 3 (age 18-49) are open label. Subjects in cohorts 1 and 2 will receive 2 vaccinations 3-4 years apart. Subjects in cohort 3 will receive 1 vaccination. All participants should be naïve of 23vPS. Comparisons of immune responses from the different cohorts will be done. Read Less

HIV vaccines may help the immune systems of HIV infected patients better control the virus. The goal of this study is to determine whether patients on anti-HIV medications can stop taking those medications if they receive an HIV vaccine. While taking anti-HIV medications, participants will receive either an HIV vaccine or a placebo. Participants will then stop taking their anti-HIV medications and the study will compare the viral loads of participants who received the vaccine with the viral loads of participants who received the placebo. Primary study hypotheses: 1)The Week 12 and Week 16 post-ART interruption geometric mean HIV-1 RNA levels will be lower among participants who had received MRK Ad5 vaccine prior to ART interruption than among participants who received placebo; 2) the time averaged area under the curve of the log10 HIV-1 RNA copies/ml versus day function in the 16 week post-ART interruption step will be lower among participants who received the MRK Ad5 vaccine prior to ART interruption than among participants who receive placebo.

Men who have sex with men (MSM) have an increased risk of developing anal human papillomavirus (HPV) infections, which can be a risk factor for anal cancer. HIV-infected women are also at risk of anal cancer. This study will evaluate the effectiveness of the Food and Drug Administration (FDA)-approved quadrivalent HPV vaccine, Gardasil, at preventing anal HPV infection in HIV-infected MSM and HIV-infected women.

The purpose of this study is to compare two flu vaccines to determine their safety and ability to stimulate an immune response in HIV infected children and adolescents. This study will also determine how often and how long people who receive a vaccine are able to spread flu vaccine virus to other people. Read Less

To evaluate, in healthy HIV-1 seronegative vaccinia-immune and vaccinia-naive volunteers, the safety and immunogenicity of an HIV-1 candidate vaccine (TBC-3B) consisting of a live recombinant vaccinia virus expressing the env, gag, and pol genes of HIV-1 IIIB strain. To evaluate the potential of boosting with one of a variety of HIV-1 recombinant subunit, peptide, or pseudovirion vaccines, if available, to augment the immune responses of the vaccinees. Antigenic drift, defined as the genetic variation of the HIV-1 envelope gene that results in antigenic variation during natural infection, may confound attempts to achieve protective immunity using a vaccine based solely on HIV-1 envelope proteins. Inclusion of conserved core and polymerase proteins along with envelope protein in a candidate vaccine may address some of the problems with antigenic variability. A prime-boost immunization approach using a novel priming immunogen expressing env, gag, and pol genes of the HIV-1 IIIB strain will be attempted in this study. Read Less

To determine the safety and immunogenicity of vaccinia-derived HIV-1 recombinant envelope glycoprotein (gp160) in asymptomatic HIV-infected adult volunteers. To compare safety and immunogenicity of two different schedules of gp160 administration. To examine the effects of gp160 and hepatitis B vaccine (Engerix-B) on various markers of viral load and on selected immune parameters. Potentiation of a patient's immune response to HIV might possibly prolong the period of clinical latency and protect the patient indefinitely. Preliminary results from a study of Immuno-AG recombinant gp160 vaccine in healthy volunteers not infected with HIV suggest that the vaccine is safe and produces antibodies against the virus. Because another previous study failed to demonstrate a specific anti-HIV response in patients injected with a recombinant vaccinia virus containing HIV-1 genes, this study is also testing the immunotherapeutic role of other immunizations (such as hepatitis B vaccination) that would be expected to induce a nonspecific immune response in HIV-infected persons.

Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a naturally occurring substance that is made by the body in response to infection or inflammation, and greatly improves cellular immune responses. The purpose of this study is to evaluate the safety and effectiveness of GM-CSF as an adjuvant to improve the immune response to hepatitis B virus (HBV) vaccination in HIV infected individuals.

Arm 1 will receive one dose of M2SR intranasally on Day 1 and one dose of QIV on Day 92. Arm 2 will receive one dose of placebo (saline) intranasally on Day 1, and one dose of QIV on Day 92. Study duration will be approximately 28 months with patient participation duration approximately 13 months. The primary study objective is to assess the safety and reactogenicity of a monovalent live attenuated influenza H3N2 M2SR vaccine. Read Less

This Phase II trial evaluates the safety and immunogenicity of two doses of the Folate Receptor Alpha (FRα) peptide vaccine mixed with GM-CSF as a vaccine adjuvant, with or without a immune priming with cyclophosphamide, as a consolidation therapy after neoadjuvant or adjuvant treatment of patients with Stage IIb-III triple negative breast cancer (TNBC).
