Approvals mentioning the linked drugs (133)

Approval records of the derived drug set, plus records whose indication text names this biomarker. Each record names its authority, jurisdiction, indication text and status — a drug approved in one jurisdiction for one indication is not 'approved' in general, and an approval listed here is not necessarily restricted to this biomarker.
