Corcept Shifts Endocrinology Leadership Amid Cushing’s Syndrome Expansion

  • Sean Maduck, President of Corcept’s Endocrinology division, to retire effective October 1, 2026.
  • Justin Gunn, former VP of Sales and Commercial Learning for Oncology, promoted to succeed Maduck.
  • Maduck to remain as senior commercial advisor to ensure smooth transition.
  • Gunn previously led commercial teams at Gilead Sciences, Merck, and Sepracor.

Corcept’s leadership transition comes as the company seeks to broaden its reach in treating Cushing’s syndrome, a niche but growing endocrinology market. The shift reflects a strategic pivot toward leveraging commercial expertise from other therapeutic areas to drive growth. With multiple clinical trials underway, the company’s ability to maintain momentum in its core endocrinology business will be critical.
