| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to assess the immune-mediated effect on plasma VL (HIV-1 RNA) of the HIV therapeutic vaccine Vacc-4x with GM-CSF adjuvant when administered prior to HIV latent reservoir activation by the HDACi romidepsin in HIV patients on ART.; Secondary Objective: To assess the safety and tolerability of Vacc-4x when administered prior to the HDACi romidepsin in HIV patients on ART. To explore the effect of Vacc-4x on HIV viral reservoir size in CD4 T cells when ad-ministered prior to the HDACi romidepsin in HIV patients on ART. To explore virus production induced by romidepsin To assess the potential additive antiviral effect of two additional booster injections of Vacc-4x when administered prior to the HDACi romidepsin in HIV patients on ART. To explore the effects of Vacc-4x on immune responses to HIV when Vacc-4x is admin-istered prior to the HDACi romidepsin in HIV patients on ART. To explore the effects of Vacc-4x on selected markers of inflammation when adminis-tered prior to the HDACi romidepsin in HIV patients on ART. ;Primary end point(s): Plasma HIV RNA levels below 20 copies/mL 72 h after each of the three romidepsin infusions.;Timepoint(s) of evaluation of this end point: End of trial | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Virological Endpoints - Change from baseline in CA US HIV RNA at visits 6, 9, 12-25. - Change from baseline in proviral DNA at visits 6, 9, 12, 13, 24 and 25. - Change from baseline in plasma HIV-1 RNA (single-copy assay) at 2 h, 24 h and 72 h after each of the three romidepsin infusions. Immunological and Inflammatory Endpoints - Change from baseline in CD4 and CD8 counts at visits 13, 24 and 25. - Change from baseline in CD4/CD8 ratio at visits 13, 24 and 25. - Change from baseline in T cell proliferation to visits 6, 9, 12, 13, 21, 22, and 23. - Change from baseline in intracellular cytokines to visits 6, 9, 12, 13, 21, 22, and 23. - Change from baseline in hs-CRP to visits 13 and 25. - Change from baseline in IP-10 to visits 13 and 25. - Change from baseline in D-dimer to visits 13 and 25 - Change from baseline in sTNF1 and sTNF2 to visits 13 and 25.
