We repurpose drugs for some the world’s most challenging medical conditions.

We are passionate about helping transform healthcare. It’s what drives us to do our best – every day.

It takes a team of dedicated, seasoned professionals with a deep understanding of intricacies of drug development to find opportunities where others see none, to tackle the toughest of diseases and conditions, to push to find a novel way forward, because lives are depending on it.

Vision. Courage. Compassion. We aspire to embody these values in everything we do.


Health. Caring.

Implementation of a successful [drug repurposing] strategy is not a simple undertaking. The skills and expertise required are considerable and range across a number of different disciplines. They include the need to access compounds and information, determine the disease area of focus and implement a well thought-through business and IP strategy.
The successful execution of a [drug repurposing] business model can result in a pipeline that has an increased number of Phase II-level compounds, as well as lead to new innovations in disease etiology and pathway/network biology.
