A Phase II Trial to Assess the Safety and Immunogenicity of DNA Priming Administered by the ID Zetajet® With or Without ID Derma Vax™ Electroporation Followed by IM MVA Boosting in Healthy Volunteers in Tanzania and Mozambique

Electroporation will increase the efficiency of DNA priming in terms of immune responses and will lead to a dose sparing DNA vaccine regimen. Furthermore increased DNA vaccine concentration will reduce the number of shots necessary to deliver the full dose and induce comparable immune responses as with lower DNA vaccine concentrations.

Antiretroviral-Sparing Concept: An Exploratory Phase II, Randomized, Single Blind Placebo-Controlled Study to Investigate the Effect of Therapeutic Immunization on the Quantity of HIV-Specific T Cell Precursors During Highly Active Antiretroviral Therapy Followed by Analytical Treatment Interruption

PHPC-02 is a phase II, randomized, placebo-controlled trial designed to investigate whether therapeutic immunization during highly active antiretroviral therapy (HAART) induces elevations of HIV-specific T cell precursors with high proliferative capacity (PHPC) in HIV-1-infected individuals, and whether the quantity of PHPC correlates with the viral load set point following analytical treatment interruption (ATI). Subjects will be randomized to receive either DermaVir Patch (8 subjects per cohort) or DermaVir Patch Placebo (8 subjects per cohort) every four weeks for three applications while receiving maximally suppressive HAART. HAART will be discontinued at Week 9 for an ATI period of 20 weeks.

A Phase II Randomized, Placebo-Controlled, Multi-Center Study to Evaluate the Safety, Tolerability, Immunogenicity, and Antiretroviral Activity of DermaVir Patch (LC002) in Treatment-Naïve HIV-1-Infected Patients

DermaVir is a synthetic pathogen-like nanomedicine. The active pharmaceutical ingredient is a single plasmid DNA expressing fifteen HIV antigens that assemble to HIV-like particles. These particles are safe; replication, integration and reverse transcription deficient. DermaVir is targeted to Langerhans cells by topical administration with DermaPrep. Langerhans cells with DermaVir migrate to lymph nodes and induce HIV-specific T cells that can kill HIV-infected cells.
GIEU006 is a Phase II randomized, placebo-controlled, dose-finding, double-blinded, multicenter study to assess the safety, tolerability, immunogenicity, and preliminary antiretroviral activity of DermaVir in antiretroviral therapy naïve adults with HIV-infection.

BACKGROUNDHIV-specific cellular immune responses are associated with control of viremia and delayed disease progression. An effective therapeutic vaccine could mimic these effects and reduce the need for continued antiretroviral therapy. DermaVir, a topically administered plasmid DNA-nanomedicine expressing HIV (CladeB) virus-like particles consisting of 15 antigens, induces predominantly central memory T-cell responses.METHODSTreated HIV-infected adults (HIV RNA <50 and CD4 >350) were randomized to placebo or escalating DermaVir doses (0.1 or 0.4 mg of plasmid DNA at weeks 1, 7, and 13 in the low- and intermediate-dose groups and 0.8 mg at weeks 0, 1, 6, 7, 12, and 13 in the high-dose group), n = 5-6 evaluable subjects per group. Immunogenicity was assessed by a 12-day cultured interferon-γ enzyme-linked immunosorbent spot assay at baseline and at weeks 9, 17, and 37 using 1 Tat/Rev and 3 overlapping Gag peptide pools (p17, p24, and p15).RESULTSGroups were comparable at baseline. The study intervention was well tolerated, without dose-limiting toxicities. Most responses were highest at week 17 (4 weeks after last vaccination) when Gag p24 responses were significantly greater among intermediate-dose group compared with control subjects [median (IQR): 67,600 (5633-74,368) versus 1194 (9-1667)] net spot-forming units per million cells, P = 0.032. In the intermediate-dose group, there was also a marginal Gag p15 response increase from baseline to week 17 [2859 (1867-56,933), P = 0.06], and this change was significantly greater than in the placebo group [0 (-713 to 297), P = 0.016].CONCLUSIONSDermaVir administration was associated with a trend toward greater HIV-specific, predominantly central memory T-cell responses. The intermediate DermaVir dose tended to show the greatest immunogenicity, consistent with previous studies in different HIV-infected patient populations.

Review

Author: Enikő R. Tőke ; Julianna Lisziewicz

Combination antiretroviral therapy (cART) successfully suppresses HIV replication. However, daily and lifelong treatment is necessary to manage patient illness because cART neither eradicates infected cells from reservoirs nor reconstitutes HIV-specific immunity that could kill infected cells. Toward the cure of HIV, different nanomedicine classes have been developed with the following disease-modifying properties: to eradicate the virus by activation of latently infected CD4+ T-cells and reservoirs flushing; to kill the infected cells in the reservoirs by boosting of HIV-specific T cells; and to prevent infection by the use of microbicides with improved epithelial penetration and drug half-life. Preclinical and clinical trials consistently demonstrated that DermaVir, the most advanced nanomedicine, induces long-lasting memory T-cell responses and reduces viral load in comparison with placebo. DermaVir and the nanomedicine pipelines have the potential to improve the health of HIV-infected people at lower costs, to decrease antiretroviral drug exposure, and to contribute to the cure of HIV/AIDS.FROM THE CLINICAL EDITORDespite the leaps and bounds in the development of antiretroviral therapy, HIV remains a significant public health challenge. In this review, applications of nanomedicine- based technologies are discussed in the context of HIV treatment, including virus elimination by activation of latently infected CD4+ T-cells; infected cell elimination in the reservoirs by boosting HIV-specific T cells, and by preventing infection by the use of microbicides with improved epithelial penetration and drug half-life.

Here we characterize the structure, stability and intracellular mode of action of DermaVir nanomedicine that is under clinical development for the treatment of HIV/AIDS. This nanomedicine comprises pathogen-like pDNA/PEIm nanoparticles (NPs) having the structure and function resembling spherical viruses that naturally evolved to deliver nucleic acids to the cells. Atomic force microscopy demonstrated spherical 100 - 200 nm NPs with a smooth polymer surface protecting the pDNA in the core. Optical absorption determined both the NP structural stability and biological activity relevant to their ability to escape from the endosome and release the pDNA at the nucleus. Salt, pH and temperature influence nanomedicine shelf-life and intracellular stability. This approach facilitates the development of diverse polyplex nanomedicines where the delivered pDNA-expressed antigens induce immune responses to kill infected cells.FROM THE CLINICAL EDITORThe authors investigated DermaVir nanomedicine comprised of pathogen-like pDNA/PEIm nanoparticles with structure and function resembling spherical viruses.
