In Silico Trials

Definition

In silico trials refer to the use of computer modeling and simulation to evaluate the safety, efficacy, or performance of medical devices, drugs, or treatments. These trials rely on virtual patient models and computational algorithms to simulate clinical scenarios, reducing the need for physical testing and live clinical trials.

Relevance to the MedTech Industry

In silico trials enable medical device and pharmaceutical manufacturers to accelerate development, reduce costs, and enhance safety by predicting device behavior and patient outcomes using virtual models. This approach supports innovation by allowing early identification of design flaws, optimizing device performance, and supplementing traditional clinical evidence.
