Abstract: The goal of the invention is to increase the therapeutical activity of oncolytic NDV. This issue is solved by a Newcastle Disease Virus comprising a recombinant nucleic acid, wherein the nucleic acid codes for a binding protein that has a therapeutic activity when expressed by the virus-infected tumor cell. Binding proteins belong to the following group: A natural ligand or a genetically modified ligand, a recombinant soluble domain of a natural receptor or a modified version of it, a peptide-ligand, an antibody molecule and derivatives thereof or antibody-like molecules like ankyrin repeat molecules or derivatives thereof.
