Pharmaceutical compositions, vaccines and their uses in the prevention or treatment of a persistent infection or of cancer

Pharmaceutical compositions and pharmaceutical combination preparations. The pharmaceutical compositions and the pharmaceutical combination preparations comprise at least one oxidative stressor selected from the group consisting of dithranol (anthralin, cignolin), or other anthrones or hydroxyanthracenes, at least one Toll-like receptor 7 (TLR7) ligand, and at least one peptide antigen. The pharmaceutical compositions or combination preparations may be used in the prevention or treatment of a persistent viral, bacterial or fungal infection or of cancer. The pharmaceutical compositions or combination preparations may find use for topical application on the skin of a human or animal body.

Vaccines

The present invention relates to particles, particularly virus-like particles (VLPs), comprising fusion polypeptides comprising selected repeat units derived from the repeating regions of Type I and Type II circumsporozoite proteins (CSP) of Plasmodium vivax (Pv), together with an amino acid sequence derived from the C-terminal PvCSP sequence. In some embodiments, the fusion polypeptide additionally comprises an amino acid sequence derived from the N-terminal PvCSP sequence and/or a surface antigen polypeptide derived from Hepatitis B virus (HBV-S). The invention also relates to nucleotide sequences coding for such fusion polypeptides, vectors and plasmids comprising such nucleotide sequences, and host cells comprising such vectors and plasmids. The invention additionally relates to compositions, particularly vaccine compositions, comprising the fusion polypeptides or VLPs for use as vaccines for the prevention of malaria.
