Our Services

esqLABS develops and utilizes OPEN-SOURCE software to create physiologically-based Quantitative Systems Pharmacology (PB-QSP) platforms as value-generating, holistic Modeling & Simulation solutions to support our customers’ decision making process along the entire life cycle of pharmaceutical products from research through development and at the point of care.

PB-QSP Platform Development

Today, in silico studies and trial simulations already complement experimental approaches in pharmaceutical R&D. However, project workflows and current software tools usually focus on isolated aspects of drug action, such as either pharmacokinetics at the organism scale or pharmacodynamic interaction (i.e. systems-biology) on the molecular level, even though biology is always multiscale by nature.

The multi-scale physiologically-based (PB) modeling concept [1] in our PB-QSP platforms make it possible to integrate…

  • multi-scale data from all biological scales (in-vitro, preclinical, individual and population-level clinical data)
  • across multiple treatments of a therapeutic area


  • build-up and transfer of actionable knowledge
  • across all phases of drug research & development


… within one single platform


This unique capability allows to link experimental in vitro model systems with observations in animal experiments and clinical trials, which improves reliability of predictions for clinical studies and their outcome.


The multi-scale physiologically-based backbone structure of our QSP platforms makes workflow development for translational modeling more consistent and efficient as with common state-of-the-art Modeling & Simulation approaches.

The PB-QSP Diabetes Platform

Our sophisticated model of glucose homeostasis …

… offers a powerful platform for research, drug development, and treatment personalization in the indication of Diabetes and metabolic diseases. The PB-QSP approach covers various scales from hormone-receptor interaction to population variability within different species. The backbone of our platform is open-source and under continuous development


  • Full PBPK representation of clinical biomarkers and treatments
    • Glucose & HbA1c, multiple Insulins, Glucagon, GLP1, GIP, SGLT2 Inhibitors …
  • … coupled with relevant PD mechanisms down to the insulin receptor level [2]
  • Relevant preclinical species: rat, monkey & minipig [3]
  • In-silico patient representations: healthy, T1DM,  T2DM
  • PK-modules: FcRn-binding, protein-Albumin binding, subcutaneous drug- and oral glucose- and meal absorption [2,4]

Informed & Validated

  • With data from clinical trials, literature & partners [2,5,6]
  • Tested in clinical trials within a closed-loop artificial pancreas system [5,6]


Efficiently leverage your preclinical experiments

  • Physiologically-based  framework to maximize learnings from animal experiments …
  • … and translation to humans for a more efficient use of animal experiments

Assess in-licensing options and new drug derivatives

  • Asses the effect of e.g. Fc-Fusion- or Albumin-binding approaches on compound PK & PD
  • Assess potential benefit of drug combinations or multi-agonist entities
  • Assess the optimal dose ratio for combination therapies

Clinical Trial Simulations

  • Optimize trial design to ensure successful outcome (cohort selection, titration rules, measurement intervals and  clinical endpoints)
  • Assess treatment benefit in different populations (T1DM vs. T2DM) 
  • Benchmark precandidates vs. competitors for an optimized marketing strategy
  • Optimize your medical device strategy by assessing effects of device properties on product & treatment efficacy
