Roivant Sciences to acquire Silicon Therapeutics to boost drug discovery capabilities


Roivant Sciences has agreed to acquire Silicon Therapeutics, a Boston-based drug design, research, and development company, for $450 million, in an all-share deal.

The Swiss biopharma company will also make additional payments to the US firm based on regulatory and commercial milestones.

Silicon Therapeutics is said to have developed a computational physics platform. The platform is used for the in silico design and optimization of small molecule drugs for challenging disease targets.

The computational physics platform includes custom methods that are based on quantum mechanics, molecular dynamics, and statistical thermodynamics.

It is said to have been designed to address the needs for predicting binding energies and conformational behavior of molecules among other key bottlenecks in drug discovery projects.

Roivant Sciences said that the acquisition will strengthen and complement its targeted protein degradation (TPD) platform.

The TDP platform will be powered by the advanced machine learning models of VantAI, which will be trained on degrader-specific experimental data and by Silicon Therapeutics’ computational physics capabilities. Roivant Sciences believes that this will help address several modality-specific challenges of degrader design and optimization.

Furthermore, the integration of Silicon Therapeutics and VantAI will help Roivant Sciences to leverage both computational physics and machine learning-based methods to drug design.
