Typically, Sanofi-Sunrise invests in those areas the company targets, such as rare disease, oncology, neuroscience, diabetes, multiple sclerosis and immunology. To date its biggest win has been investing with Third Rock Ventures in MyoKardia, a company focused on precision therapies for genetic heart diseases that lead to heart failure. After plowing more than $150 million in equity financing in MyoKardia and $45 million in Sanofi resources, the company went public in 2015.
