5 Different Kinds of Cytokine Release Assays: Weathering the Storm | CRA Post II

In our previous post, we outlined the dangers of Cytokine Release Syndrome (CRS) and the importance of preclinical Cytokine Release Assays (CRAs) when developing monoclonal antibodies (mAbs) that interact with the patient’s immune system. In this second post, we describe the different kinds of assays in use and how these may fit into your drug development program. An alternative type of CRA, peripheral blood mononuclear cell (PBMC) blood outgrowth endothelial cell (BOEC) co-culture, will be discussed in more detail in our next blog post.

In Vitro Cytokine Release Assays: Is There Calm After the Storm? | CRA Post I

What is a cytokine storm? 

Cytokine Release Syndrome (CRS), otherwise known as cytokine storm, is a systemic inflammatory response caused by complications due to disease, infection or an adverse effect of biologic therapy. The clinical symptoms of a cytokine storm are massive release of a potent cocktail of pro-inflammatory cytokines into the general circulatory system, leading to severe multi-organ damage, failure or potentially death. This is an extremely unwanted immunotoxicological side effect in drug development.

The Next Frontier for Cancer Immunotherapy Trials

With its measurable impact on patient survival, there’s no denying that immunotherapy is Cancer Immunotherapy Trialsalready causing momentum in ways that cancer is treated. Drug researchers and developers are identifying new candidates in their growing pipelines and exploring combinations of immunotherapies, while regulatory agencies are providing expedited review and approval of these therapies for new indications at an unprecedented rate.

With checkpoint inhibitors from ipilimumab (Yervoy®) to nivolumab (Opdivo®) to pembrolizumab (Keytruda®) to the most recently approved atezolizumab (TecentriqTM), each breakthrough has provided new insights on how the immune system can be activated and manipulated to fight a variety of cancers.
