• Effective September 5, 2023, Idorsia Pharmaceuticals U.S. Inc. to be led by Tausif ('Tosh') Butt who brings more than 20 years of pharmaceutical leadership experience.
• Patricia "Patty" Torr to step down to pursue other opportunities.

RADNOR, Pa., Aug. 31, 2023 /PRNewswire/ -- Idorsia Pharmaceuticals U.S. Inc. today announced that Tausif ('Tosh') Butt will join the organization as the new President and General Manager on September 5, 2023. Tosh succeeds Patty Torr who is leaving Idorsia to pursue other opportunities.

Jean-Paul Clozel, MD and Chief Executive Officer of Idorsia commented:
"Patty joined Idorsia in March 2020 as the first U.S. commercial employee, establishing the U.S. organization and preparing for our first product launch – both major undertakings which were made even more complicated during the COVID-19 pandemic. Under Patty's leadership, the U.S. team has driven demand and product adoption for QUVIVIQ and made progress in securing reimbursement. I would like to thank Patty for leaving Idorsia U.S. with a solid foundation to build upon and I wish her all the best in her future endeavors."

Jean-Paul Clozel continued:
"Tosh has a rich expertise spanning complex operations, and the commercialization of products across different disease areas and medical settings. I believe he will bring the approach we need for the U.S. organization's current priorities, and his reputation for delivering results is impressive. I'm very happy with the confidence Tosh is placing in Idorsia, and our approach to ensuring long-term sustainability of the company."

Tosh Butt, BSc, MSc, commented:
"I have not taken the decision to join Idorsia lightly. I've spoken to the executive team and looked at their strategy for the future of Idorsia – I am truly excited to work on a product with such potential as QUVIVIQ and at a company with the ability to innovate. I am certain that I bring valuable experience and can lead the U.S. team to commercial success. I'm looking forward to gathering the team together and starting to face our challenges head-on from day one."
