Sepsis is a life-threatening condition affecting one million people per year\nin the US in which dysregulation of the body's own immune system causes damage\nto its tissues, resulting in a 28 - 50% mortality rate. Clinical trials for\nsepsis treatment over the last 20 years have failed to produce a single\ncurrently FDA approved drug treatment. In this study, we attempt to discover an\neffective cytokine mediation treatment strategy for sepsis using a previously\ndeveloped agent-based model that simulates the innate immune response to\ninfection: the Innate Immune Response agent-based model (IIRABM). Previous\nattempts at reducing mortality with multi-cytokine mediation using the IIRABM\nhave failed to reduce mortality across all patient parameterizations and\nmotivated us to investigate whether adaptive, personalized multi-cytokine\nmediation can control the trajectory of sepsis and lower patient mortality. We\nused the IIRABM to compute a treatment policy in which systemic patient\nmeasurements are used in a feedback loop to inform future treatment. Using deep\nreinforcement learning, we identified a policy that achieves 0% mortality on\nthe patient parameterization on which it was trained. More importantly, this\npolicy also achieves 0.8% mortality over 500 randomly selected patient\nparameterizations with baseline mortalities ranging from 1 - 99% (with an\naverage of 49%) spanning the entire clinically plausible parameter space of the\nIIRABM. These results suggest that adaptive, personalized multi-cytokine\nmediation therapy could be a promising approach for treating sepsis. We hope\nthat this work motivates researchers to consider such an approach as part of\nfuture clinical trials. To the best of our knowledge, this work is the first to\nconsider adaptive, personalized multi-cytokine mediation therapy for sepsis,\nand is the first to exploit deep reinforcement learning on a biological\nsimulation.\n
