New Whitepaper: An Introduction to Immunotherapy and the Promise of Tissue Phenomics™

Jun 11, 2014 3:52:00 AM

Nearly every day there seems to be exciting news or developments in the field of immunotherapy and immuno-oncology. Not only can you read all about immunotherapy research in leading scientific journals (1), but the mainstream media now reports on the latest immunotherapy clinical trial results from pharmaceutical companies.

But what exactly is immunotherapy and what technologies are needed to realize its full potential for the treatment of cancer? Throughout this whitepaper, Definiens will answerthose questions as well as provide insight into other commonly asked questions about immunotherapy:

  • Why is it predicted that 60% of cancer treatments will be based on immunotherapy in the next 10 years?
  • What are some of the more common approaches to immunotherapy today?
  • What will be needed to accurately identify patients that will respond to immunotherapy treatment?
  • How can knowing a patient’s immune status predict long-term treatment success?
  • How is the use of Tissue Phenomics™ enabling effective clinical decision-making in oncology?

ITOC 2014: Toll Like Receptor 7 Agonists for Cancer Immunotherapy

Watch Dr. Stefan Enders describe two approaches that redirect the body’s own immune system to attack cancer. The first involves utilizing TLR7 receptors to activate NK cells to kill cancerous tumors. The second approach involves activating the immune system while down-regulating production of proteins that tumor cells need to survive.

Cancer Immunotherapy: Hot With Promise, Potential Breakthroughs
If there’s a science equivalent to the Oscars, or People magazine’s Sexiest Man Alive, this might be it: last year Cancer Immunotherapy – a technique that harnesses the body’s own immune system to fight cancer — was named Science magazine’s “breakthrough of the year.”

NIH study demonstrates that a new cancer immunotherapy method could be effective against a wide range of cancers
A new method for using immunotherapy to specifically attack tumor cells that have mutations unique to a patient’s cancer has been developed by scientists at the National Cancer Institute (NCI), part of the National Institutes of Health. The researchers demonstrated that the human immune system can mount a response against mutant proteins expressed by cancers that arise in epithelial cells which can line the internal and external surfaces (such as the skin) of the body. These cells give rise to many types of common cancers, such as those that develop in the digestive tract, lung, pancreas, bladder and other areas of the body.

New Cancer Immunotherapy Aims Powerful T Cells Against Tumors
Deadly skin cancers in mice shrank in response to a new treatment that may complement other “immunotherapies” developed recently to boost the body’s own defenses against disease threats, according to a new study published by UC San Francisco researchers in the May 2014 edition of the Journal of Experimental Medicine.

Advances in Immunotherapy for the Treatment of Non-Small Cell Lung Cancer
Despite recent developments in targeted therapies, the overall survival for metastatic NSCLC remains poor. The need for novel therapeutic options has led to the development of various new immunotherapeutic agents including anti-PD-1 and anti-PD-L1 antibodies, which appear to have a promising role in the treatment of the disease. Additionally, other immunotherapy options including CTLA-4 inhibitors and various vaccines are also currently being investigated as potential treatment options.

Featured Articles Of The Month (March, 2014): How Image Analysis Supports Immunotherapy

Mlecnik, B. et al. Functional Network Pipeline Reveals Genetic Determinants Associated with in Situ Lymphocyte Proliferation and Survival of Cancer Patients. Science Translational Medicine 6, Nr. 228 (19. März 2014): 228ra37. doi:10.1126/scitranslmed.3007240.

The tumor microenvironment is host to a complex network of cytokines that contribute to shaping the intratumoral immune reaction. Chromosomal gains and losses, coupled with expression analysis, of 59 cytokines and receptors and their functional networks were investigated in colorectal cancers. Changes in local expression for 13 cytokines were shown. Metastatic patients exhibited an increased frequency of deletions of cytokines from chromosome 4. Interleukin 15 (IL15) deletion corresponded with decreased IL15 expression, a higher risk of tumor recurrence, and reduced patient survival. Decreased IL15 expression affected the local proliferation of B and T lymphocytes. Patients with proliferating B and T cells at the invasive margin and within the tumor center had significantly prolonged disease-free survival. These results delineate chromosomal instability as a mechanism of modulating local cytokine expression in human tumors and underline the major role of IL15. Our data provide further mechanisms resulting in changes of specific immune cell densities within the tumor, and the importance of local active lymphocyte proliferation for patient survival.

Paolino, M. et al. The E3 Ligase Cbl-B and TAM Receptors Regulate Cancer Metastasis via Natural Killer Cells“. Nature, 19. Februar 2014. doi:10.1038/nature12998.

Tumour metastasis is the primary cause of mortality in cancer patients and remains the key challenge for cancer therapy1. New therapeutic approaches to block inhibitory pathways of the immune system have renewed hopes for the utility of such therapies2. Here we show that genetic deletion of the E3 ubiquitin ligase Cbl-b (casitas B-lineage lymphoma-b) or targeted inactivation of its E3 ligase activity licenses natural killer (NK) cells to spontaneously reject metastatic tumours. The TAM tyrosine kinase receptors Tyro3, Axl and Mer (also known as Mertk) were identified as ubiquitylation substrates for Cbl-b. Treatment of wild-type NK cells with a newly developed small molecule TAM kinase inhibitor conferred therapeutic potential, efficiently enhancing anti-metastatic NK cell activity in vivo. Oral or intraperitoneal administration using this TAM inhibitor markedly reduced murine mammary cancer and melanoma metastases dependent on NK cells. We further report that the anticoagulant warfarin exerts anti-metastatic activity in mice via Cbl-b/TAM receptors in NK cells, providing a molecular explanation for a 50-year-old puzzle in cancer biology3. This novel TAM/Cbl-b inhibitory pathway shows that it might be possible to develop a ‘pill’ that awakens the innate immune system to kill cancer metastases. Read more
