Therapeutic human immunodeficiency virus (HIV) vaccines aim to reduce disease progression by inducing HIV-specific T cells. Vacc-4x are peptides derived from conserved domains within HIV-1 p24 Gag. Previously, Vacc-4x induced T cell responses in 90% of patients which were associated with reduced viral loads.

In a previous phase II trial this immunized 90% of 38 patients on antiretroviral treatment (ART) after intradermal delivery in conjunction with local granulocyte-macrophage colony-stimulating factor (GM-CSF) as adjuvant. In this study, 22 responders were retested for cellular memory at a median 7.
