Corcept Announces Planned Leadership Transition
Sean Maduck to Retire; Justin Gunn Appointed President, Endocrinology
REDWOOD CITY, Calif. – September 23, 2026 – Corcept Therapeutics Incorporated (NASDAQ: CORT), a commercial-stage company engaged in the discovery and development of medications to treat severe endocrinologic, oncologic, metabolic and neurologic disorders by modulating the effects of the hormone cortisol, today announced the retirement of Sean Maduck, President of the company’s Endocrinology division. Justin Gunn will succeed Mr. Maduck and will fully assume his new responsibilities starting October 1. Mr. Gunn will join the company’s Executive Team, and will report to Joseph K. Belanoff, M.D., Corcept’s Chief Executive Officer. To enable a smooth transition, Mr. Maduck will remain with the company as a senior commercial advisor.
“Few leaders have made the kind of impact Sean has made over his remarkable career. The work he has led over the past 14 years has helped and will continue to help thousands of patients living with Cushing’s syndrome. I am grateful to Sean for his willingness to continue on as an advisor, particularly as we look ahead to what’s next for our Endocrinology business,” said Dr. Belanoff.
“In the two years since he joined Corcept, Justin has proven himself to be an outstanding commercial leader,” Dr. Belanoff continued. “The medical community is beginning to understand the true prevalence and impact of Cushing’s syndrome, and that means Corcept has an opportunity to reach and help many more patients. I am confident in Justin’s ability to lead this important work.”
Mr. Gunn joined Corcept in July 2024 as Vice President of Sales and Commercial Learning for the company’s Oncology division. In his tenure at Corcept, he designed and built an entirely new field sales and training organization to support the successful launch of Lifyorli®, the company’s medicine for the treatment of platinum-resistant ovarian cancer, approved in combination with nab-paclitaxel. Prior to Corcept, Mr. Gunn spent nearly 18 years with Gilead Sciences, where he led commercial sales teams in a diversity of therapeutic categories, including cardiovascular disease, respiratory disease, oncology and virology. He previously held marketing and sales roles of increasing seniority at Merck and Sepracor. Mr. Gunn holds a Bachelor of Science degree in business administration from the University of Arkansas.
