In Silico Cloning of Target Type 2 Diabetes Population for Treatments Development and Decision Support.
Abstract:
Therapies for treatment of type 2 diabetes (T2D) involve a variety of medications, depending on the stage of T2D progression. It is now an accepted knowledge that in silico trials can help to accelerate drug development and support treatment optimization. A T2D simulator (T2DS), consisting of a model of the glucose-insulin system and an in silico population describing glucose-insulin dynamics in T2D subjects, has been recently developed based on early-stage T2D data, studied with sophisticated experimental techniques. This limits the domain of validity of the simulator to this specific sub-population of T2D. Here we proposed a method for tuning the T2DS to any desired T2D target population, e.g. insulin-naïve (i.e., not experienced with insulin) patients, without the need to resort to complex and expensive clinical studies. This will allow to use the T2DS for testing treatments in the target population. To illustrate the methodology, we used a case study: extending the T2DS to reproduce the behavior of insulin-naïve T2D subjects. The methodology described here can be extended to other stages of T2D, allowing an extensive in silico testing phase of different treatments before human trials.
Insights
A new method tunes type 2 diabetes (T2D) simulators for diverse patient groups, including insulin-naïve individuals. This advances in silico trials for drug development and treatment optimization in T2D.
Area of Science:
- Computational biology
- Pharmacology
- Endocrinology
Background:
- Type 2 diabetes (T2D) treatments vary by disease stage.
- In silico trials accelerate drug development and optimize treatments.
- Existing T2D simulators are limited to early-stage T2D data.
Purpose of the Study:
- To develop a method for tuning T2D simulators to specific patient populations.
- To enable in silico testing of treatments in diverse T2D subpopulations without extensive clinical studies.
Main Methods:
- Proposed a method to adapt a T2D simulator (T2DS) to new target populations.
- Utilized a case study to extend the T2DS for insulin-naïve T2D subjects.
- Demonstrated tuning without complex clinical studies.
Main Results:
- Successfully adapted the T2DS to simulate insulin-naïve T2D patient behavior.
