Bristol Myers Squibb is reorganizing its research and development operations in a move designed to accelerate decisions across the drug pipeline. The company announced the leadership transition on Thursday, November 12, 2026, in a Bristol Myers Squibb press release.

Unified R&D Leadership Starts January

Effective January 1, 2027, Cristian Massacesi will lead a unified, end-to-end research and development organization. Massacesi is currently the company's executive vice president, chief medical officer and head of development.

The new structure will bring scientific and clinical expertise into one organization spanning discovery through development. Bristol Myers Squibb said the aim is to strengthen collaboration, accelerate decision-making and improve portfolio execution.
