Provided is a method of treating a bladder cancer in an animal or human comprising: administering to an animal or human patient a therapeutic composition comprising a first fusion protein capable of specifically binding to an epidermal growth factor receptor (EGFR) on the surface of a cancer cell and comprising an epidermal growth factor (EGF) polypeptide conjugated to a bacterial toxin polypeptide and a second fusion protein comprising an anthrax Lethal Factor N-terminus (LF) conjugated to a Diptheria Toxin A (DTA) catalytic domain.

Method of treating a bladder cancer using a chimeric EGF-targeted bacterial toxin

The invention provides multivalent fibronectin-integrin binding compositions and methods of use thereof. In certain embodiments, the invention provides peptide compositions that include at least two fibronectin binding peptides coupled together as a cancer therapeutic or a diagnostic tool.

Multivalent fibronectin-integrin binding compositions and methods of use thereof

Composition and methods are disclosed for utilizing microaggregation of FAP-containing complexes to promote their fast internalization. This approach allows the uptake of cytotoxic cargo coupled to either FAP-Antibodies or FAP-liposome complexes by tumor bladder cells. Importantly, this approach is efficient even under serum-free conditions such as the ones found in the lumen of the bladder.
