GSK Secures Japan Approval for Hibsago and FDA Priority Review for Jemperli
GSK reports two regulatory milestones: Hibsago has secured its first approval in Japan as the first and only treatment described as delivering a functional cure for chronic hepatitis B. It blocks viral DNA replication and lowers hepatitis B surface antigen to support longer-lasting control for some patients. Separately, the FDA granted priority review for Jemperli for locally advanced rectal cancer, which remains under review.
