This study will evaluate the safety, immunogenicity, and preliminary assessment of efficacy of a novel vaccine encoding conserved elements (CE) of the HIV-1 Gag core protein, p24Gag, as a therapeutic vaccine in HIV-1 infected persons who are on antiretroviral therapy (ART). The study aims to induce potent virus-specific cytotoxic T lymphocytes (CTL) responses.
This study will evaluate the safety, immunogenicity, and preliminary assessment of efficacy of a novel vaccine encoding conserved elements (CE) of the HIV-1 Gag core protein, p24Gag, as a therapeutic vaccine in HIV-1 infected persons who are on antiretroviral therapy (ART).
The study will randomly assign participants to one of three groups. Participants in Arm 1 will receive p24CE1/2 pDNA vaccine at Weeks 0 and 4, followed by p24CE1/2 pDNA admixed with full-length p55^gag pDNA vaccine at Weeks 12 and 24. Participants in Arm 2 will receive full-length p55^gag pDNA vaccine at Weeks 0, 4, 12, and 24. Participants in Arm 3 will receive placebo at Weeks 0, 4, 12, and 24.
Study visits will occur at Weeks 0, 4, 6, 12, 24, 26, and 48 and may include physical examinations and blood and urine collection. Some participants may undergo leukapheresis and stool sample collection.

Evaluating the Safety, Tolerability, and Immunogenicity of a Prime-Boost Regimen of HIV-1 Nef/Tat/Vif, Env pDNA Vaccine Delivered Intramuscularly With Electroporation and HIV-1 rVSV envC Vaccine in Healthy, HIV-Uninfected Adults
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 stom...
Objectives of this trial are to: Evaluate the kinetics and magnitude of the CMV-specific immune response post-Towne challenge (3000 pfu) in healthy CMV-seronegative volunteers who receive...

Six patients will receive IFx-Hu2.0 on an outpatient basis at a single time point in a single lesion, two lesions, or three lesions, as a monotherapy (a maximum of three lesions could be i...
The purpose of the study is to determine the safety of a new HIV vaccine and to evaluate the immune response to the vaccine. Only some HIV genes are used to make the vaccine and therefore...
We evaluated the storage stability of powder containing naked plasmid DNA (pDNA) and hyaluronic acid (HA) or mannitol (Man) prepared by the spray-freeze-drying technique, through which we have reporte...
In this study, we investigated the design and construct of a chitosan-based targeted gene delivery system and evaluated its function. To this end, chitosan-folic acid/pDNA (CA-FA/pDNA) nanoparticles w...
Recent advances in electrospinning are yielding intricate scaffolds for use in regenerative medicine. To explore the possibility of creating bioactive scaffolds with functional gene expression systems...
The delivery of plasmid DNA (pDNA) using polycations has been investigated for several decades; however, obstacles that limit efficient gene delivery still hinder the clinical application of gene ther...
A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.
A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)
A bacterial vaccine for the prevention of brucellosis in man and animal. Brucella abortus vaccine is used for the immunization of cattle, sheep, and goats.
A live attenuated virus vaccine of chick embryo origin, used for routine immunization of children and for immunization of adolescents and adults who have not had mumps or been immunized with live mumps vaccine. Children are usually immunized with measles-mumps-rubella combination vaccine.
A live attenuated virus vaccine of chick embryo origin, used for routine immunization of children and for immunization of adolescents and adults who have not had measles or been immunized with live measles vaccine and have no serum antibodies against measles. Children are usually immunized with measles-mumps-rubella combination vaccine. (From Dorland, 28th ed)
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
