Artificial Intelligence Systems for Modeling the Gut
BLACKSBURG, VA —May 21, 2017—The BioTherapeutics Inc. team has developed a revolutionary computational pipeline to test and predict the efficacy of existing and novel treatments against Clostridium difficile infection (CDI). The study is published within Artificial Intelligence in Medicine.
The computational pipeline incorporates mechanistic ordinary differential equation (ODE) based models with stochastic simulation and an ensemble of advanced machine-learning (ML) methods. The new modeling pipeline is able to translate preliminary animal results to clinical outcomes, identify impactful unforeseen mechanistic insights of treatments, examine dosage effects, and predict synergisms or antagonisms of combination therapies.
Modeling systems, such as this one, have the potential to revolutionize the design of clinical trials. Integration of patient characteristics from electronic health records (EHR), from molecular to clinical cohort scales, can create virtual avatars for the pre-emptive and predictive in silico testing of safer, more effective therapeutics and for advanced analytics to identify new molecular biosignatures as biomarkers capable of defining a patient’s response to treatment.
The ability to predict progression of disease and response to treatment is of particular importance in CDI and other infectious and immune-mediated diseases. The majority of healthcare costs and mortality resulting from CDI are caused by high rates of recurrence that can exceed 50% of patients depending on the treatment. The current primary treatments in CDI are antibiotics which can worsen disease in certain cases due to a reduction in the native commensal microbiome. Emerging treatments, such as fecal microbiome transplantation (FMT), are designed to prevent recurrence of disease.
The article also includes the first data depicting the effect of lanthionine synthetase C-like (LANCL2) agonists during gastrointestinal bacterial infections. When treated with LANCL2 ligands, C. difficile infected mice were protected against mortality and experienced a five-fold reduction in the severity of disease symptoms. Both computational and experimental methods suggested that this effect might be a result of an induction of regulatory T cells in response to the activation of LANCL2.
“Our modeling shows that we do not need to remove the pathogen nor directly influence inflammation in the case of CDI to have an effective treatment,” said Andrew Leber, Scientific Director at BioTherapeutics. “Simply restoring immune tolerance through an LANCL2, or similar immunoregulatory pathway, or boosting the gut microbiome to allow it to naturally outcompete pathogenic C. difficile strains is effective in the absence of antibiotics.”
This study serves as a critical first step toward demonstrating the feasibility of constructing precision medicine tools that rather than using the typical one-size-fits-all approach, can optimize treatment design on a patient-by-patient basis. The application of these methods to personalized treatment of human diseases can potentially minimize undesirable side effects and maximize efficacy of treatment in response to C. difficile and other infectious and immune mediated diseases such as inflammatory bowel disease.
“The convergence of advanced data analytics, modeling and advanced artificial intelligence systems with high resolution, large-scale clinical data creates an opportunity to fundamentally transform and strengthen how clinical therapeutic decisions are made as a complement to traditional medical knowledge,” said Josep Bassaganya-Riera, President and CEO of BioTherapeutics. “This study and our continuing efforts illustrates our leading role in this developing field of precision medicine. The next steps of this informatics technology involve its implementation to accelerate a personalized path to cures in infectious and immune-mediated diseases.”
