Developing a unified QSP platform for lysosomal storage disorders (LSDs)
Develop a unified modeling platform for LSDs to enhance the comprehension of Lysosomal storage disorders by highlighting differences and common properties...
Develop a logical model describing the interplay between Bispecific T-cell engager antibodies (BiAbs) the immune system, and tumor cells. Perform in silico simulations to elucidate the factors affecting the cytokine release syndrome (CRS). Identify effectiveness of co-medications to administer with BiAbs molecules to mitigate CRS without affecting the efficacy.
The logical model was built focusing on the major variables influencing the CRS activation and the tumor cell elimination. The rules governing the interactions were defined based on known biology and published experimental evidence. The syndrome severity was described by the phenotypic readout Combined Cytokine Index CCI used as a local proxy for the CRS observed in the clinical setting. The efficacy of co-meds was assessed by performing a sensitivity analysis of CCI and tumor with respect to model mutations (nodes knock-down or over-activation).
The model developed enables a systematic analysis in which is possible to test combinatorially single or multiple co-meds treatments to provide together with BiAbs. The minimal requirement of information to set up the model and the qualitative outcome of the results makes it ideal for exploratory analysis.
