Vaccines Treatment Options in Pennsylvania

The purpose of this study is to evaluate the immune response to the Vaccine Research Center (VRC) rAd5 HIV vaccine when the vaccine components are administered in three different ways, in healthy, HIV-uninfected adults. Read Less

Some vaccines may work better when given together with another substance known as an adjuvant or when given with an experimental procedure called electroporation (EP). EP is a method where an electric pulse is administered to the same muscle where the vaccine injection is given. The addition of the adjuvant to the vaccine and the delivery with EP may increase a person's immune response to the vaccine. Combination approaches such as a DNA vaccine followed by live vector boost may also increase a person's immune response to the vaccine components. All of these interventions will be tested in this study. This study will evaluate the safety and tolerability of and immune response to an HIV DNA vaccine with or without plasmid IL-12 adjuvant, when given by EP and followed by a live vector vaccine given IM by needle and syringe in healthy, HIV-uninfected adults.

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

NOTE: This study has stopped enrolling new participants, and all study vaccinations for currently enrolled participants have been stopped. Currently, there are no vaccines approved for the prevention of HIV infection, but there are many clinical trials taking place that are studying experimental HIV vaccines. The purpose of this study is to evaluate the safety and tolerability of three different HIV vaccine schedules in healthy, HIV-uninfected adults. Read Less

The purpose of this study is to evaluate the safety and tolerability of an HIV-1 nef/tat/vif, env pDNA vaccine delivered with electroporation (EP), followed by a recombinant vesicular stomatitis virus (rVSV) HIV envC vaccine boost, in healthy, HIV-uninfected adults. Read Less

The purpose of this study is to evaluate immunologic response to different types of influenza vaccine among children/adolescents/young adults 4-21 years of age. This is a randomized controlled trial (RCT), that will assess immune response in about 440 participants (about 220 per vaccine arm) pre- and post-vaccination to FluMist (live attenuated influenza vaccine given by nasal administration) and Flucelvax (egg-free cell-culture inactivated influenza vaccine).

RATIONALE: Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cyclophosphamide may also stimulate the immune system in different ways and stop tumor cells from growing. Giving vaccine therapy together with cyclophosphamide after surgery may cause a stronger immune response to kill any remaining tumor cells. It may also prevent or delay the recurrence of melanoma. PURPOSE: This randomized phase I/II trial is studying the side effects of vaccine therapy when given with or without cyclophosphamide and to see how well they work in treating patients who have undergone surgery for stage II, stage III, or stage IV melanoma.

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 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 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.

The purpose of this study is to assess if there is any immune interference between the Porcine circovirus free (PCV-free) liquid Human rotavirus (HRV) vaccine and routine infant vaccinations currently in use in the US, namely Pediarix®, Hiberix® and Prevenar 13® as compared to the currently licensed lyophilized formulation of the HRV vaccine when co-administered with the same routine vaccinations in healthy infants 6-12 weeks of age Read Less

This study will evaluate the feasibility, safety, and efficacy of intradermal vaccination of prostate cancer patients with alpha-type-1-polarized dendritic cells (DC1) loaded with apoptotic allogeneic tumor (LNCap). The study will target men with recurrent prostate cancer, who failed local therapy, have no measurable metastasis, but have a rising PSA with a doubling time of less than 10 months. The selection of this study group enables us to evaluate time to PSA progression, a highly relevant, clinical primary endpoint of efficacy in this two arm study. In order to facilitate infiltration of vaccination-induced T cells into tumor site(s) and to reduce tumor-specific tolerance, subjects will receive the vaccine in combination with limited androgen ablation (AA) with a LHRH analogue for 3 months. Subjects will be randomly assigned to one of two cohorts. In cohort A subjects will be first treated with limited AA alone for 3 months, and at the time of PSA relapse (PSA ≥ 1 ng/dL) will receive the DC vaccine in conjunction with AA. In cohort B, the sequence of treatment will be reversed. Efficacy will be estimated as the within-subject difference in time to PSA relapse following the combination treatment as compared to the AA alone, thus, each subject will serve as his own control. All subjects will commence the DC1-based vaccination 2 weeks prior to treatment with the LHRH analogue. Each subject will receive 1 intradermal (i.d.) dose of the vaccine at weeks 1, 5, 9, and 13 for a total of 4 doses. Additional courses of vaccination may be administered to subjects without evidence of disease progression every 3 months (±1 month) for up to 12 months depending on the number of doses originally produced and available after the 4 intended protocol doses. All doses of the vaccine will be administered intradermally (i.d.). Read Less
