Ivan received his scientific training in inflammation research at sanofi. Before he started Adipeau, he founded two successful companies. Plexcera Therapeutics developed a treatment for a rare pediatric genetic disease (Farber Disease). When Ivan started Plexcera, there was only one living patient with Farber. He sold the company to a large public biotech company. After Plexcera, he started MyPersonalTherapeutics, which identified patient-specific drug combinations for colon cancer. The company built genetically complex fruit fly avatars representing individual human cancers and conducted massive clinical studies in the fruit flies.
