UChicago, Evelo Biosciences sign licensing deal for microbiome-based cancer immunotherapy

(University of Chicago) Evelo Biosciences and the University of Chicago have announced that they have entered into an exclusive worldwide license agreement to develop and commercialize a microbiome-based cancer immunotherapy. The cancer therapy, developed in the laboratories of Thomas Gajewski, professor of medicine and pathology at UChicago, employs select gut microbes to boost the immune system's attack on cancer cells and improve the efficacy of anti-cancer drugs.

The host immune system plays a pivotal role in the emergence of tumor cells that are refractory to multiple clinical interventions including immunotherapy, chemotherapy, and radiotherapy. Here, we examined the molecular mechanisms by which the immune system triggers cross-resistance to these interventions. By examining the biological changes in murine and tumor cells subjected to sequential rounds of in vitro or in vivo immune selection via cognate cytotoxic T lymphocytes, we found that multimodality resistance arises through a core metabolic reprogramming pathway instigated by epigenetic loss of the ATP synthase subunit A...

The immunologic landscape of tumors has been continuously unveiled, providing a new look at the interactions between cancer cells and the immune system. Emerging tumor cells are constantly eliminated by the immune system, but some cells establish a long-term equilibrium phase leading to tumor immunoediting and, eventually, evasion. During this process, tumor cells tend to acquire more mutations. Bearing a high mutation burden leads to a greater number of neoantigens with the potential to initiate an immune response. Although many tumors evoke an immune response, tumor clearance by the immune system does not occur due to a ...

This article provides an overview of AZD1775, based on English peer-reviewed articles on MEDLINE. The authors highlight the data from the published preclinical and clinical studies. Expert opinion: A majority of the current clinical trials focus on AZD1775 combined with chemotherapy or radiation. Treatment with AZD1775 was tolerated and antitumor activity has been observed, especially in patients with advanced malignancies harboring G1 checkpoint aberrations and/or DNA damage repair defects. Thus, identification of the molecular subtypes that benefit most from the treatment with AZD1775 alone or in combination may provide ...

AbstractIn this White Paper, we discuss the current state of microbial cancer therapy. This paper resulted from a meeting ( ‘Microbial Based Cancer Therapy’) at the US National Cancer Institute in the summer of 2017. Here, we define ‘Microbial Therapy’ to include both oncolytic viral therapy and bacterial anticancer therapy. Both of these fields exploit tumor-specific infectious microbes to treat cancer, have sim ilar mechanisms of action, and are facing similar challenges to commercialization. We designed this paper to nucleate this growing field of microbial therapeutics and increase interactions ...

Authors: Rybarczyk-Kasiuchnicz A, Ramlau R Abstract Lung cancer is the main cause of cancer-related deaths in Poland. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are a new group of agents for non-small-cell lung cancer (NSCLC) patients. Determining the predictive value of activating mutations in the EGFR and ROS-1 genes and ALK rearrangement in non-small-cell lung cancer has enabled the identification of patients likely to achieve true clinical benefits. EGFR-TKIs may produce objective response in more than 60% of patients and prolong progression-free survival to 10 months in mutation-posit...

As immunotherapies continue to emerge as a standard component of treatment for a variety of cancers, the imperative for testing these in combination with other standard cancer therapies grows. Radiation therapy may be a particularly well-suited partner for many immunotherapies. By modulating immune tolerance and functional immunogenicity at a targeted tumor site, radiation therapy may serve as a method of in situ tumor vaccination. In situ tumor vaccination is a therapeutic strategy that seeks to convert a patient's own tumor into a nidus for enhanced presentation of tumor-specific antigens in a way that will stimulate and...

CONCLUSIONS: FRα is overexpressed in high-grade TNBC and post-chemotherapy residual tumors. It participates in cancer cell signaling and presents a promising target for therapeutic strategies such as antibody-drug conjugates, or passive immunotherapy priming Fc-mediated anti-tumor immune cell responses.

Neurologic complications of systemic cancer therapy encompass a range of symptoms that can affect the central nervous system (CNS), peripheral nervous system (PNS), or both. Their incidence will likely increase as novel agents, such as targeted therapy and immunotherapy, become incorporated into standard treatment regimens, and the number of long-term cancer survivors rises. Recognizing the common adverse effects of treatment is important to avoid misdiagnosis of cancer recurrence in the nervous system or paraneoplastic disease. Ongoing has focused on identifying patient-specific risk factors that predispose to drug toxici...
