Safety and Immunogenicity of a Vaccine Dendritic Cell-based Pulsed With Autologous Heat-inactivated in HIV-1 Infected Patients
July 25, 2019 updated by: Judit Pich Martínez
Safety and Immunogenicity of a Vaccine Dendritic Cell-based Pulsed With Autologous Heat-inactivated HIV in HIV-1 Infected Patients. Prospective, Randomized, Partially Blinded Study
single-center, national clinical trial, phase I, randomized (1: 1: 1: 1), prospective, placebo-controlled, partially masked, parallel group.
Patients will be assigned to one of the following four arms: 3 immunizations of dendritic cells / 3 immunizations of dendritic cells with pegylated interferon + / 3 immunizations of placebo / 3 immunizations of placebo with pegylated interferon.
