Advaxis is an American company devoted to the discovery, development and commercialization of immunotherapies based on a technology platform which uses engineered Listeria monocytogenes . The company is headquartered in Princeton, New Jersey and was incorporated in Delaware in 2006.The Lm-based platform on which the company's products are based involves the use of attenuated Lm which secrete antigen/adjuvant fusion proteins and stimulate a patient's immune system to mount an immune response to the secreted antigen; if the antigen is specifically found on cancerous cells, then the result aims to be an effective immune response targeting and eliminating the cancer. Treatments developed using this paradigm are referred to as Lm-LLO immunotherapies.Today, the Company has over fifteen distinct constructs in various stages of development, directly developed by the Company and through strategic collaborations with recognized centers of excellence such as: the National Cancer Institute, Cancer Research – UK, the Wistar Institute, the University of Pennsylvania, and the Department of Homeland Security among others.The Company also has a veterinary medicine program that is evaluating an Lm-LLO based immunotherapy in a Phase 1 study in canine osteosarcoma.

Patent
Advaxis | Date: 2015-02-18

This invention provides methods and compositions for using evaluating biomarker expression in a disease and providing a multi-targeted Listeria-based immunotherapeutic approach against said disease. In a related aspect, the invention relates to a method of treating a disease in a subject, the method comprising the steps of: a. obtaining a biological sample from said subject; b. evaluating the expression of a predetermined number of biomarkers in said biological sample; c. administering to said subject a composition comprising a recombinant Listeria strain, said strain comprising a nucleic acid sequence encoding at least one fusion protein, wherein said fusion protein comprises a biomarker identified in said biological sample, wherein said biomarker is associated with said disease, wherein said biomarker is fused to a PEST-containing polypeptide, and wherein each fusion protein within said Listeria comprises a different biomarker, thereby treating said disease in said subject.


The present invention provides methods of treating, protecting against and inducing an immune response against a tumor or cancer, comprising the step of administering to a subject a recombinant Listeria strain. In one embodiment the present invention relates to a recombinant Listeria strain, said recombinant Listeria strain comprising a recombinant nucleic add, said nucleic add comprising a first open reading frame encoding a recombinant polypeptide comprising a first N-terminal fragment of an LLO protein fused to a heterologous antigen or fragment thereof, and wherein said recombinant nucleic add further comprises a second open reading frame encoding a mutant PrfA protein.


Patent
Advaxis and University of Pennsylvania | Date: 2017-01-04

This invention provides compositions and methods for treating and vaccinating against a HER2eu antigen-expressing tumor and inducing an immune response against the same in a subject.


Patent
Advaxis and The United States As Represented By The Secretary | Date: 2017-05-24

The present invention is directed to compositions comprising an immune checkpoint inhibitor or a T cell stimulator or a combination thereof, and a live attenuated recombinant Listeria strain comprising a fusion polypeptide comprising a truncated Listeriolysin O protein, a truncated ActA protein, or a PEST amino acid sequence fused to a tumor-associated antigen. The invention is further directed to methods of treating, protecting against, and inducing an immune response against a tumor or a cancer, comprising the step of administering the same.


Patent
