Efficacy Of Combination Of Immunotherapies In A Murine In A Murine Squamous Cell Carcinoma Model, E. Correia, C. Portocarrero, U. Rodeck

Phase 1

Introduction: Head and neck squamous cell carcinomas (HNSCCs) are a type of neoplasm found in the epithelium of the oral cavity, oropharynx, nasopharynx, larynx, or hypopharynx. Recent evidence has demonstrated that 70-90% of HNSCC are associated with Human Papillomavirus (HPV), particularly strain 16 producing oncogenic proteins E6/E7. Currently, HNSCCs are treated with surgery, chemotherapy, and radiation, however immunotherapy with immune checkpoint (PD-1) blocking agents promises to improve outcomes in HNSCC.

Objective: This study examined the therapeutic effects of dual and triple combination immunotherapies in a mouse model of HPV-associated HNSCC.

Methods: Treatment modalities included a tumor vaccine (attenuated Listeria monocytogenes …

Listeria Monocytogenes As A Vector For Cancer Immunotherapy: Current Understanding And Progress, John C. Flickinger, Ulrich Rodeck, Adam E. Snook

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Listeria monocytogenes, a Gram-positive facultative anaerobic bacterium, is becoming a popular vector for cancer immunotherapy. Indeed, multiple vaccines have been developed utilizing modified Listeria as a tool for generating immune responses against a variety of cancers. Moreover, over a dozen clinical trials testing Listeria cancer vaccines are currently underway, which will help to understand the utility of Listeria vaccines in cancer immunotherapy. This review aims to summarize current views on how Listeria-based vaccines induce potent antitumor immunity and the current state of Listeria-based cancer vaccines in clinical trials. © 2018 by the authors.
