About
Vial is a clinical research organization (CRO) founded in 2020 by Simon Burns and Jason Wang and headquartered in San Francisco, California. The company has built a technology-enabled model for running clinical trials that differs from traditional CROs by directly partnering with clinical practices — particularly in dermatology and ophthalmology — and converting them into research sites. Vial handles the full operational burden: regulatory and IRB submissions, site staff training, clinical equipment provisioning, electronic data capture (EDC) setup, and patient recruitment and scheduling. This allows clinics with no prior research experience to participate in trials, dramatically expanding the pool of available sites and accelerating patient enrollment timelines.
