Biomarker · Other

AR-V7 splice variant

A constitutively active androgen receptor splice variant lacking the ligand-binding domain, detected in circulating tumor cells or tissue by RT-PCR or immunostaining; studied as a predictive marker of resistance to AR-pathway inhibitors in castration-resistant prostate cancer.

Approvals mentioning the linked drugs (43)

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.
