Short description
Dwivedi2014 - Crohns IL6 Disease model - Anti-IL6R Antibody
This model is comprised of four models:
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 Crohn's Disease model are 3a, 4d, 4e, 4f and 5b.

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 (2014) 3, e89; doi:10.1038/psp.2013.64; advance online publication 8 January 2014.

Figure 3a: Reduction of CRP from baseline with administration of Tocilizumab, an anti IL6-R antibody. Doses of 560 mg every 2 weeks and 4 weeks were simulated. Simulated as two time courses, 2 weeks and 4 weeks. The antibody Kd was matched to Tocilizumab for this case (1 nmol/l). Figure 4d: Concentration of serum IL6, gut IL6 serum CRP and Gut pSTAT3 with a monthly (672 h) 300 mg dose regimen of IL6-R antibody. Simulated as a Time Course for 2016 h. Figure 4e: Suppression of CRP by IL6-R antibody after 12 weeks of monthly (672 h) doses. Three separate Kd values were assessed: 2.5, 25 and 250 pmol/l. Simulated with a two-paramater scan for Dose and Kd, Plotted using LibreCalc. Figure 4f: IL6-R antibody concentration in serum for 200 and 500 mg doses administered monthly (672 hours). Simulated as a parameter scan for Dose between 200 and 500 with 1 interval. Figure 5b: Suppression of CRP after 12 weeks of varied monthly (672 hours) doses. This simulation includes binding of the antibody to the ligand-receptor complex. Three separate Kd values were assessed: 2.5, 25 and 250 pmol/l. Simulated with a two-paramater scan for Dose and Kd, Plotted using LibreCalc
