Swiss pharmaceutical company Idorsia has begun searching for a new CEO after Srishti Gupta stepped down from the role she assumed last summer. Chairman Jean-Paul Clozel is leading the executive search process. The company's shares dropped more than 13% following the announcement.

The leadership change marks another period of instability for Idorsia, which has now experienced multiple CEO transitions in recent years. Gupta's tenure lasted less than a year, highlighting ongoing challenges in maintaining consistent executive leadership at the biotech firm.
