Patent number: 8241623Abstract: The present invention uses co-expression of protease inhibitors and protease sensitive therapeutic agents that results in their localized production within the target tissue and inactivation outside of the target tissue, thereby increasing therapeutic activity and reducing the systemic toxicity. Inactivation is also accomplished by engineering protease degradation sites within the therapeutic construct for proteases, preferably those that are under-expressed within the target tissue yet present in non-target tissues within the body, resulting in therapeutic activity within the target tissue and inactivation outside of the target tissue. Novel chimeric proteins secreted by bacteria are also described. The chimeric proteins include chimeric toxins targeted to neoplastic cells and cells of the immune system. Novel combination therapies of these protease inhibitor:chimeric toxin-expressing bacteria together with small-molecule and biologic agents are also described.Type: GrantFiled: February 9, 2010Date of Patent: August 14, 2012Inventor: David Bermudes

Publication number: 20050249706Abstract: The present application discloses the preparation and use of attenuated tumor-targeted bacteria vectors for the delivery of one or more primary effector molecule(s) to the site of a solid tumor. The primary effector molecule(s) of the invention is used in the methods of the invention to treat a solid tumor cancer such as a carcinoma, melanoma, lymphoma, or sarcoma. The invention relates to the surprising discovery that effector molecules, which may be toxic when administered systemically to a host, can be delivered locally to tumors by attenuated tumor-targeted bacteria with reduced toxicity to the host. The application also discloses to the delivery of one or more optional effector molecule(s) (termed secondary effector molecules) which may be delivered by the attenuated tumor-targeted bacteria in conjunction with the primary effector molecule(s).Type: ApplicationFiled: March 17, 2005Publication date: November 10, 2005Inventors: David Bermudes, Ivan King, Caroline Clairmont, Stanley Lin, Michael Belcourt
