Vaccines Treatment Options in Maryland

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.

The purpose of this study is to determine if 2 doses of Pneumococcal Conjugate Vaccine (PCV) followed by 1 dose of Pneumococcal Polysaccharide Vaccine (PPV) in HIV-infected children on anti-HIV therapy is helpful and safe in fighting pneumococcal infections in this group of children. This study will also look at the protection provided by childhood vaccination against measles, pertussis, and hepatitis B virus. Pneumococcal infections are the most common AIDS-related infection in HIV-infected children. PCV may help reduce the chances of HIV-infected children getting pneumococcal infections. This study will look at whether pneumococcal vaccines are safe and effective in HIV-infected children receiving HAART. It will look at whether HIV-infected children are protected by childhood vaccines received previously and if more doses are safe and improve protection. Read Less

The purpose of this study is to evaluate the safety of and immune response to an HIV vaccine, administered using two different devices, followed by a vaccine boost, in healthy, HIV-uninfected adults. Read Less

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 assess whether HIV-infected infants who receive a heptavalent pneumococcal conjugate vaccine have more local reactions at the site of injection and systemic reactions than placebo subjects. To assess whether this vaccine is more immunogenic than placebo following the third vaccination. Children with HIV infection are at increased risk for invasive pneumococcal infection, particularly bacteremia. A large proportion of pneumococcal disease is caused by a limited number of serotypes. The maximum number of pneumococcal serotypes that can be included in a new conjugate vaccine is felt to be limited by the amount of carrier protein. A heptavalent pneumococcal conjugate vaccine has been developed that consists of pneumococcal capsular saccharides from serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F bound to a diphtheria toxin mutant carrier protein.

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.

The purpose of the study is to determine the safety of and immune response to a DNA HIV vaccine followed by an adenoviral vector HIV vaccine in HIV uninfected adults. Read Less

The purpose of this study is to determine the safety and efficacy of a VRC DNA/rAd5 vaccine regimen in healthy, circumcised men and male-to-female (MTF) transgender persons who have sex with men. NOTES: As of April 2013, all vaccinations in this study have been stopped. As of June 2017, this study has been closed. Read Less

The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of the respiratory syncytial virus (RSV) candidate vaccine when first administered via intramuscular (IM) injection according to a 0, 1-month schedule to RSV-seropositive infants aged 12 to 23 months. Read Less

This is a research study about an experimental (investigational) oral inactivated whole cell Shigella flexneri 2a killed vaccine (Sf2aWC). Sf2aWC is a killed vaccine that is being made to prevent disease from Shigella., which causes bloody, watery diarrhea. Infants and children living in developing countries experience the greatest consequences of this disease. The purpose of this study is to find a dose of the vaccine that is safe, tolerable, and develops an immune response. About 82 healthy adults, ages 18-45, will participate in this study. This study will require volunteers to stay in the research facility for several nights for the first dose. Participants in Cohorts 2, 3, and 4 will not be required to stay overnight for the second and third doses. Participants will be assigned to receive 1 of 4 vaccine doses by mouth. Study procedures include: stool samples, blood samples and documenting side effects. Participants will be involved in study related procedures for about 8 months. 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).

Background: Metastatic castration resistant prostate cancer (mCRPC) keeps growing even when the amount of testosterone in the body is reduced to very low levels. mCRPC is incurable. Researchers want to develop vaccines to teach the immune system to target and kill cancer cells. They want to test three of these vaccines (ETBX-071, ETBX-061, and ETBX-051) against mCRPC. Objective: To test the safety of combination ETBX-071, ETBX-061, and ETBX-051 and to study their effects on the immune system. Eligibility: People ages 18 and older with mCRPC that has not responded to standard therapies Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Computed tomography (CT) or magnetic resonance imaging (MRI) scans Bone scan Participants will get the vaccines as shots under the skin every 3 weeks for 3 doses. They may then have the shots every 8 weeks for up to 1 year. Participants will keep a diary to record any symptoms from the vaccines. Participants will have blood tests each time they get the vaccines. They will also have scans and other tests to measure the effect the vaccines have on their tumors. Participants will have a visit within 28 days after their last treatment. This includes a physical exam and blood and urine tests. Participants will then be contacted by phone every 3 months for the first year, every 6 months for the next 2 years, and every 12 months for another 2 years. Participants will be asked to join a long-term follow up study. Read Less
