The purpose of Idorsia is to discover, develop, and commercialize innovative medicines to help more patients.
We have more ideas, we see more opportunities, and we want to transform the horizon of therapeutic options.
Idorsia US was established in 2020 to drive the company into a new phase and realize our ambition of bringing innovative medicines from bench to bedside.

With commercial operations based outside of Philadelphia, PA, one of densest communities of life sciences talent in the world, our goal is to build the commercial footprint that will deliver Idorsia’s deep pipeline of products from its drug discovery engine to the US market – changing the lives of many patients. We have assembled a diverse and highly regarded leadership team, with decades of experience across therapeutic areas.

We think big, and we go big. Our aim is to bring innovative medicines to the millions of patients that could benefit from our innovation.
