Merck splits Human Health into Oncology and Specialty units and names new commercial leaders

Merck reorganized its Human Health business into an Oncology unit and a Specialty, Pharma and Infectious Diseases unit, and created a Strategic Access, Policy and Communications group. Jannie Oosthuizen was named executive vice president and president of Oncology and MSD International, and Brian Foard, formerly of Sanofi, leads the specialty unit from March 2, 2026. Both report to Chairman and CEO Robert Davis, and the company says the structure supports launches and a late-stage pipeline of roughly 80 Phase 3 studies.
