A Phase I Safety and Immunogenicity Trial of Live Recombinant Canarypox ALVAC-HIV (vCP205) and HIV-1 SF-2 rgp120 in HIV-1 Uninfected Adult Volunteers

2014-08-27 03:59:55 | BioPortfolio

Summary

To evaluate the safety and immunogenicity of high-titered ALVAC-HIV MN120TMG (vCP205) given sequentially or simultaneously with rgp120/HIV-1SF2 in MF59 adjuvant emulsion in HIV-negative volunteers.

ALVAC-HIV vCP205 is a second-generation candidate vaccine that can be used to induce a humoral and cellular response against several antigens. vCP205 expresses proteins from two strains of HIV (MN and LAI). rgp120/HIV-1SF2 expresses proteins from a different strain of HIV. This study will help to show how the immune system responds to proteins from more than one strain of virus.

Description

ALVAC-HIV vCP205 is a second-generation candidate vaccine that can be used to induce a humoral and cellular response against several antigens. vCP205 expresses proteins from two strains of HIV (MN and LAI). rgp120/HIV-1SF2 expresses proteins from a different strain of HIV. This study will help to show how the immune system responds to proteins from more than one strain of virus.

Six groups of 25 volunteers each are randomized to receive simultaneous or sequential doses of ALVAC-HIV vCP205 and SF2 rgp120 or control vaccines (ALVAC-RG rabies glycoprotein vCP65 or BIOCINE Placebo Vaccine 2). In each group, 21 volunteers receive vaccine and 4 receive control vaccines. Volunteers are stratified by lower or higher risk sexual behavior. Immunizations are given to three groups at months 0, 1, 3, 6, 9, and 12, and to the other three groups at months 0, 1, 6, 9, and 12. Volunteers are followed for 24 months.

Medical and Biotech [MESH] Definitions

Vaccines or candidate vaccines used to prevent and treat RABIES. The inactivated virus vaccine is used for preexposure immunization to persons at high risk of exposure, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis.

A genus of the family RHABDOVIRIDAE that includes RABIES VIRUS and other rabies-like viruses.

The type species of LYSSAVIRUS causing rabies in humans and other animals. Transmission is mostly by animal bites through saliva. The virus is neurotropic multiplying in neurons and myotubes of vertebrates.

A 170-kDa transmembrane glycoprotein from the superfamily of ATP-BINDING CASSETTE TRANSPORTERS. It serves as an ATP-dependent efflux pump for a variety of chemicals, including many ANTINEOPLASTIC AGENTS. Overexpression of this glycoprotein is associated with multidrug resistance (see DRUG RESISTANCE, MULTIPLE).

Platelet membrane glycoprotein IIb is an integrin alpha subunit that heterodimerizes with INTEGRIN BETA3 to form PLATELET GLYCOPROTEIN GPIIB-IIIA COMPLEX. It is synthesized as a single polypeptide chain which is then postranslationally cleaved and processed into two disulfide-linked subunits of approximately 18 and 110 kDa in size.
