Dwivedi2014 - Healthy Volunteer IL6 Model

Dwivedi2014 - Healthy Volunteer IL6
Model
This model is comprised of four models:

[BIOMD0000000534]
Healthy Volunteer model

[BIOMD0000000535]
Crohn's Disease - IL-6 Antibody

[BIOMD0000000536]
Crohn's Disease - sgp130FC

[BIOMD0000000537]
Crohn's Disease - IL-6Ra Antibody

Possible avenues for Interleukin-6 (IL-6) inhibition in
treating Crohn's disease are compared here. Each model refers to
separate ligands. The system simulates differential activity of the
ligands on the signalling of IL-6.
This affects Signal Transducer and Activator of
Transcription 3 (STAT3) activity on the production of
biomarker C-Reactive Protein (CRP) expression.
Figures referring to this Healthy Volunteer model are 2c and
2d.

Abstract:

In this study, we have developed a multiscale systems model
of interleukin (IL)-6-mediated immune regulation in Crohn's
disease, by integrating intracellular signaling with
organ-level dynamics of pharmacological markers underlying the
disease. This model was linked to a general pharmacokinetic
model for therapeutic monoclonal antibodies and used to
comparatively study various biotherapeutic strategies targeting
IL-6-mediated signaling in Crohn's disease. Our work
illustrates techniques to develop mechanistic models of disease
biology to study drug-system interaction. Despite a sparse
training data set, predictions of the model were qualitatively
validated by clinical biomarker data from a pilot trial with
tocilizumab. Model-based analysis suggests that strategies
targeting IL-6, IL-6R?, or the IL-6/sIL-6R? complex are less
effective at suppressing pharmacological markers of Crohn's
than dual targeting the IL-6/sIL-6R? complex in addition to
IL-6 or IL-6R?. The potential value of multiscale system
pharmacology modeling in drug discovery and development is also
discussed.CPT: Pharmacometrics & Systems Pharmacology
