Research Area | Emergent Neural Networks to Redesign Clinical Testing of Medicines and Learning from Real World Evidence

Real World Data (RWD) and Real World Evidence (RWE) are playing an increasing role in healthcare decisions to support innovative use of Electronic Health Records and other digital sources to help patients and physicians with experimental and existing treatments (Project link). For example: phase 3 clinical trials evaluating new therapies and vaccines are among the most complex experiments performed in medicine. Around 50% of phase 3 trials fail and in some cases lead to adverse events. This high failure rate also counteracts patients consenting to treatments by experimental drugs as a last resort. The United States Food and Drug Administration (FDA) states that another significant challenge is the difficulty of predicting clinical results in a wider patient base in the real world vs. controlled randomized trials. We invent explainable AI and machine learning systems that learn from diverse and inclusive datasets for ethical clinical use and testing of experimental medicines. For example, we have described novel and non-trivial reward functions for self-learning Reinforcement Learning (RL) algorithms for dose de-es… View full description

Real World Data (RWD) and Real World Evidence (RWE) are playing an increasing role in healthcare decisions to support innovative use of Electronic Health Records and other digital sources to help patients and physicians with experimental and existing treatments (Project link). For example: phase 3 clinical trials evaluating new therapies and vaccines are among the most complex experiments performed in medicine. Around 50% of phase 3 trials fail and in some cases lead to adverse events. This high failure rate also counteracts patients consenting to treatments by experimental drugs as a last resort. The United States Food and Drug Administration (FDA) states that another significant challenge is the difficulty of predicting clinical results in a wider patient base in the real world vs. controlled randomized trials. We invent explainable AI and machine learning systems that learn from diverse and inclusive datasets for ethical clinical use and testing of experimental medicines. For example, we have described novel and non-trivial reward functions for self-learning Reinforcement Learning (RL) algorithms for dose de-escalation studies during clinical trials to alleviate chemotherapy toxicity. These algorithms learn reward contribution from physician actions and patient states/health without future survival/outcomes information to solve fundamental problems in clinical development of medicines (Project link). In another effort, we are leveraging the use of observational RWD and RWE to supplement randomized data to train neural networks cognizant of causal inference. In collaboration with regulatory agencies and clinical partners, we are also initiating a regulatory path for AI and ML software as a medical device and digital medicines developed in our laboratory from this research  (Project linkProject link). Our research classifies, predicts and enriches novel digital endpoints to benefit patient health, eliminate adverse events, and improve outcomes. This work has significant impact on the ethical decisions facing patients and their families, and regulatory decisions for US FDA and European Medical Agency (Project link).
