Purpose:
By protecting and stimulating HIV-specific CD4 cell responses, treatment of primary HIV infection (PHI) with potent quadruple HAART could lead to prolonged suppression of HIV replication after cessation of antiretroviral therapy. The QUEST trial investigates this hypothesis and aims to determine whether addition of a therapeutic vaccine to HAART increases the likelihood of prolonged viral suppression compared to HAART alone.
Method:
148 patients with PHI were recruited. Participants were treated with open-label HAART for at least 76 weeks. Participants with sustained viremia <50 copies/mL were randomized to one of three 5-month, double-blinded study treatment groups: HAART alone, HAART + ALVAC-HIV (vCP1452), or HAART + ALVAC-HIV (vCP1452) + Remune. After a further month of HAART alone, all treatment was stopped where plasma HIV-1 RNA remained at <50 copies/mL. Intensive virologic and immunologic monitoring during a 24-week observation period followed treatment interruption. Patients who met treatment reintroduction criteria were offered HAART rescue.
