M aky Zanganeh is a trailblazing biotech executive and the co-CEO and President of Summit Therapeutics. An Iranian immigrant who fled her home country during the Iran-Iraq war, she built a remarkable career in the healthcare sector, starting as a dentist in France before earning an MBA and moving into the corporate world. She gained prominence as the Chief Operating Officer of Pharmacyclics, where she played a pivotal role in the development of the blockbuster cancer drug Imbruvica and the company's subsequent $21 billion acquisition by AbbVie in 2015.

Following that success, Zanganeh joined Summit Therapeutics, partnering again with billionaire Robert Duggan, whom she married in 2024. At Summit, she has been instrumental in securing the licensing rights for ivonescimab, a promising lung cancer drug that has shown potential to outperform existing standard-of-care treatments. Her leadership and significant equity stake in Summit Therapeutics have made her one of the few self-made female billionaires in the biotech industry. She is also a published author and cancer survivor.
