The embodiment of the invention is a virus-like particle vector, a process for the manufacture thereof, use of the virus-like particle vector and a pharmaceutical composition, which contains the virus-like particle vector. The vector is intended for the delivery of therapeutic agents into specific mammalian tissues, especially low molecular weight agents, in particular low molecular weight anti-cancer drugs into cancer tissues. More specifically, the invention relates to the virus-like particle vector, which constitutes an adenoviral dodecahedron with the therapeutic substance encapsulated or covalently linked.
