SEF.KMU with Martine und Jean-Paul Clozel

Martine and Jean-Paul Closel are CSO and CEO of Indoria Pharmaceuticals, the company they spun out of their previous biotech company, Actelion, in 2017. After the sale, stopping the kind of work they did was unimaginable for the couple. Still driven to pursue research, the couple saw founding Indorsia as a perfect solution. Optimistic from the beginning, they describe the early process as being much easier than their first company. Being able to draw on familiar employees, more financial resources and still highly motivated significantly ameliorated the process. Indorsia maintains a fascinating portfolio of research, including sleep medication in the third phase of testing that could provide a more natural sleep than other concurrent medications. Jean- Paul Closel describes the world as changing, and believes that while one shouldn’t forget past successes, it is still important to adapt and prepare for the future.
