Patent CA-2582937-A1 (CA)
Inventor: BALLY MARCEL
IPC: A61K9/127
Filed: 2005-10-06
Abstract: The invention relates to the formation of multivalent antibody constructs for testing and therapeutic purposes. In one embodiment the constructs consist of antibodies or antibody fragments conjugated to liposomes. The constructs are employed in a cell-based in vitro assay for comparing the therapeutic activity of antibodies or antibody fragments in multivalent form to the same antibodies or fragments in bivalent, free form. The assay is useful for identifying antibodies having potential in vivo activity. Selected antibodies may then be tested in an animal model of a disease state, such as cancer or an autoimmune disorder. Co-delivery of antibodies and chemotherapeutics may also be investigated. In accordance with the invention, a significant enhancement in the activity of antibodies such as trastuzumab and rituximab was observed when these antibodies were presented in the multivalent liposomal form. Key cell survival signaling molecules were down-regulated upon treatment with the multivalent liposomal antibody construct. The invention demonstrates the potential of liposome technology to enhance the therapeutic effect of antibodies via a mechanism that modulates cell survival, likely through clustering of target/antibody complex.
