“At GSK, [we leverage] technology and remote services in order to make trials more accessible for participation. Science 37’s innovative services meant we could bring the trial to the [homes of patients] in rural areas who would typically have to travel hundreds of miles to the nearest clinical site…”
–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.”
