"Science 37’s innovative services meant we could bring the trial to the homes or neighborhoods of patients in rural areas who would typically have to travel hundreds of miles to the nearest clinical site, which may otherwise have been a barrier to participating..."
–Brandon Maggio, Global Head of Digital Operations & Process Optimization, GSK
"The people involved in the trial make all the difference. Especially in an oncology trial where a nurse comes into your home for two hours at a time; it means a lot if they’re personable and you don’t feel like you’re being treated like a statistic, you’re being treated like a human."
