Vaccines Treatment Options in Maryland

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

The purpose of this study is to assess the immunogenicity, reactogenicity and safety of the GSK Biologicals HZ/su candidate vaccine when its first dose is co-administered with Pneumovax 23™ vaccine in adults aged 50 years or older.The impact of HZ/su vaccine on Pneumovax 23™ vaccine immune response will also be evaluated.

The purpose of this study is to test the safety and effectiveness of a new malaria vaccine, the DNA-Ad vaccine. The study is specifically looking at a vaccine regimen against Plasmodium falciparum, the most deadly form of malaria. Read Less

The purpose of this study is to compare the immune responses of two different doses (1.0 mg and 2.0 mg) and two different dosing schedules (two doses or three doses) of a mixed Hantaan virus (HTNV) and Puumala virus (PUUV) DNA vaccine in healthy participants. To maintain a blind, participants in the two-dose group will receive one dose of normal saline placebo. All of the groups will also receive a booster dose 6 months after first vaccination. The results will help to determine which dose and vaccination schedule will be best to move forward in the vaccine development process. Read Less

This is a single-center, randomized, single-blinded study of the Hantaan virus HTNV DNA vaccine alone, Puumala virus PUUV DNA vaccine alone, and mixed Hantaan/Puumala HTNV/PUUV DNA vaccines delivered intramuscularly IM by the needle-free PharmaJet Stratus DSJI device. Read Less

Due to recent concern of biowarfare and bioterrorism, the US government is making efforts to improve its ability to protect citizens against the smallpox virus. This study will evaluate safety of IMVAMUNE®, an investigational smallpox vaccine, and its ability to stimulate the immune system (the body's defense system). Two vaccine preparations have the same name but one is a liquid and one is a powder that has liquid added just before it is given. The vaccine that comes as a liquid will be injected (given as a shot) just under the skin (subcutaneously) or injected between the layers of the skin (intradermally). The powder formulation is only injected just under the skin. Approximately 495 adults, age 18 older born after 1971, which have not had smallpox vaccine before, may participate in the study for about 7 months. Read Less

The purpose of this study is to evaluate end of shelf-life potency in terms of the immunogenicity and safety of GSK Biologicals' trivalent MMR vaccine, by comparing it to Merck \& Co., Inc.'s MMR vaccine, which is approved for use in the United States (US). Read Less

The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' trivalent MMR (Priorix), comparing it to Merck's MMR vaccine (M-M-R II), which is approved for use in the US in healthy children 12 to 15 months of age. Read Less

The purposes of the clinical trial are to determine whether the SA4Ag vaccine can prevent postoperative Staphylococcus aureus infections in patients who are undergoing elective spinal fusion surgery, and to evaluate the safety of SA4Ag in patients who are undergoing elective spinal surgery.
