Jean-Paul Clozel

Meet Jean-Paul Clozel

Jean-Paul founded Actelion in 1997, together with his wife and work colleagues and friends, and has since built Actelion from a start-up to a multi-billion market capitalization company – acquired by Johnson & Johnson for €27.9 billion in 2017. As part of the transaction with J&J, Actelion spun out its drug discovery operations and early-stage clinical development assets into a newly created company, Idorsia, which Jean-Paul now heads up.
