Because of the potential risk of the MRK Ad5 vaccine in subjects with a strong immune response against adenovirus 5 buy malegra dxt 130 mg with visa erectile dysfunction drugs sublingual, the parallel Phambili trial in South Africa was terminated as well 130 mg malegra dxt mastercard muse erectile dysfunction medication reviews. In Phambili, the MRK Ad5 vaccine showed no efficacy, with 33 new HIV-1 infections (4. The STEP trial raises important questions that can be answered only by further exam- ination of infected subjects and transmitted viruses. The fact that the increased infec- tion risk was only seen in subjects with high antibody titers against the Ad5 vector argues against a general risk of immunizing against HIV-1, but it demonstrates the important issue of pre-existing vector immunity. The optimal priming of the immune response by a vaccine seems to be a key element determining the success or failure of a vaccine. More basic research is needed for a better understanding of the mech- anisms of HIV-1 immunological control. Because of the unfavourable effects of pre- existing immunity against the adenovirus 5 vector, other adenoviral vectors are currently developed from less frequent adenovirus serotypes. So far, two Phase 1 studies in healthy volunteers have demonstrated the immunogenicity of new HIV- 1 vaccines based on the adenovirus serotypes AD26 (AD26. In contrast to the STEP trial, the RV144 study (Rerks-Ngarm 2009) involving more than 16,000 volunteers in Thailand showed a modest protective effect with a significant reduction of new HIV-1 infections by about 31%. The vaccine was Sanofi Pasteur’s canarypox vector-based ALVAC HIV (vCP1521) expressing HIV-1 subtype B gag and protease and subtype E envelope in combination with AIDSVAX B/E gp120 proteins (MN rgp120/HIV-1 plus A244 rgp120/HIV-1). Among the 8,198 subjects receiving placebo, 74 new HIV-1 infections were observed during the three years follow-up compared to 51 infections among the other half of volunteers that had received four immunizations with the ALVAC HIV and two immunizations with AIDSVAX B/E gp120 glycoproteins within a six month period. The vaccine had no effect on viral set points and the clinical course of HIV-1 infection in the subjects infected (Rerks-Ngarm 2012). This was probably due to the fact that the vaccine induced only gp120-specific CD4 T cells (in 33% of the vaccinees), but almost no gag-specific CD4 T cells (in 1% of vaccines) and no HIV-1-specific CD8 T cells (measured by intracellular cytokine staining ICS). In contrast, almost every vaccinee developed high titer antibodies, although these antibodies only had a weak to mod- erate capacity to neutralize various HIV-1 strains. The mechanisms of the protective effect of the vaccine are still unresolved. It has been hypothesized that antibody- dependent cellular cytotoxicity (ADCC) may have played a role. Recent data indi- 50 The Basics cate a protective role of IgG antibodies to variable regions 1 and 2 (V1V2) of HIV-1 envelope proteins, whereas plasma IgA antibodies to gp120 were associated with higher rates of infections, presumably due to interference with epitope recognition by the protective IgG antibodies (Haynes 2012). Another efficacy trial, the HVTN 505 study, started enrolment in 2009 (Hammer 2013). This study tested a prime-boost vaccination regimen. After three immuniza- tions (week 0, 4, 8) with a DNA vaccine (6 plasmids: HIV-1 Clade B gag, pol, nef, and env of clades A, B and C), the subjects were vaccinated at week 24 with a mixture of four recombinant adenovirus 5 vectors (containing a gag-pol-fusion protein, and three env of clades A, B and C). Beyond 4 weeks after full immunization (week 28+), HIV-1 infections were observed in 27 of the 967 subjects in the vaccine arm (annual incidence: 2. The vaccine had no influence on viral set points in the infected subjects although the vaccination had induced HIV-1-specific T cells and antibodies. However, the vaccine did not induce neutralizing antibodies and the IgG antibody response to the V1/V2 loop was much lower than in the RV144 study in which V1/V2-specific IgG antibodies were associated with a lower risk of HIV-1 infection. A very interesting new approach is the use of a rhesus monkey cytomegalovirus (RhCMV) vector containing recombinant SIV genes. In rhesus monkeys, this vector induced a persistant and broad CTL response with induction of unusual non-cano- nical CD8 T cells restricted by HLA-II antigens which are not downregulated by the viral nef protein (Hansen 2013b). So far, it is unknown whether this non-canonical HLA-II – restricted CD8 T cells exist also in humans and whether they can be induced by vaccination. A promising approach for the development of more effective HIV-1 vaccines is the therapeutic immunization of HIV-1-infected patients on ART who then undergo a treatment interruption (Harrer 2005). The analysis of a vaccine’s ability to control HIV-1 replication during treatment interruption may be a good instrument in iden- tifying vaccines that are also effective in prevention.
