OnCore Log-in

OnCore serves as the Clinical Trial Management System, facilitating clinical research operations at Johns Hopkins Medicine. This online platform enables thorough management of clinical research studies, offers robust reporting capabilities, facilitates enrollment tracking, and ensures accurate clinical research billing.

All studies with a prospective reimbursement analysis (PRA) will require the use of OnCore. For studies without a PRA, the use of OnCore is optional.
