Jazz Pharmaceuticals announced the appointment of Thomas Riga as Chief Business Officer, effective January 1, 2026. Mr. Riga joined Jazz in April 2025 through the acquisition of Chimerix Inc., where he served as chief operating and commercial officer. In that role, he directed corporate strategy including the successful sale of Chimerix to Jazz.
In addition to leading the transaction process and alliance management at Chimerix, he helped navigate a complex regulatory environment leading to successful U.S. approval and launch of the first approved therapy for H3K27M-mutant diffuse midline glioma affecting approximately 2,000 children and young adults in the U.S. annually. He brings more than 25 years of experience in the pharmaceutical industry leading sales and marketing, business development, operations, and has held multiple C-suite positions across various organizations. In his role as chief business officer, he will lead execution of corporate development initiatives and drive strategic partnerships for the company.
He combines a passion for patients with deep commercial, operational, and corporate development expertise, having led over $2 billion in business development deals in the past five years. Tom played a pivotal role in the approval and launch of Modeyso? (dordaviprone), the first treatment for an ultra-rare, aggressive brain tumor affecting primarily children and young adults.
His commitment to patients who previously had no options is truly inspiring.
