Abstract

L'invention concerne un procédé d'encapsulation de plasmides, d'oligonucléotides ou de médicaments négativement chargés dans des liposomes présentant une composition lipidique différente entre leur bicouches membranaires intérieure et extérieure et capables d'atteindre des tumeurs primaires et leurs métastases après une injection intraveineuse administrée à des animaux et à des humains. Le procédé de formulation comprend une formation de complexe entre l'ADN avec des molécules lipidiques cationiques, et des conjugués de peptides fusogènes/NLS composés d'une chaîne hydrophobe d'environ 10-20 acides aminés et contenant également au moins quatre résidus d'histidine ou NLS au niveau de leur unique extrémité. Les molécules encapsulées présentent une efficacité thérapeutique dans l'éradication d'une variété de tumeurs humaines solides comprenant, notamment, le carcinome mammaire et le carcinome prostatique. Une combinaison de plasmides, d'oligonucléotides ou de médicaments chargés négativement, associée à d'autres médicaments antinéoplasiques (le cis-platine chargé positivement, la doxorubicine) encapsulés dans des liposomes, peut présenter une valeur thérapeutique. Les combinaisons de plasmides, oligonucléotides ou médicaments chargés négativement encapsulés avec HSV-tk plus du ganciclovir encapsulé peuvent également présenter une valeur thérapeutique.
