Galapagos’ Vision

Pioneering Research to Create Unique Targeted Therapies

Driven by a need to make great things happen, we’ve used state-of-the-art human biotechnology to discover and develop unique therapies.


Discovery icon


A bold and agile approach to drug discovery, powered by the philosophy: If it doesn’t happen, make it happen.

Biotech icon


Cutting-edge biotech that uses human cells from patients to discover novel targets for medicines to beat severe diseases.

Platform icon


A unique discovery platform that uses a vast adenoviral library to identify specific protein targets at the root cause of chronic disease, develop small molecule therapies aimed at those novel targets, and bring molecules rapidly to clinical trials.
