Xpovio: The First and Only FDA-Approved Oral XPO1 Inhibitor
Xpovio, discovered by US-based Karyopharm Therapeutics Inc. (Nasdaq:KPTI), is the world’s first and only FDA-approved oral XPO1 inhibitor. It is utilized in the treatment of hematological malignancies. Karyopharm had previously licensed the rights for the drug to Antengene for distribution in Greater China, South Korea, and ASEAN countries in May 2018. Xpovio received conditional approval in China in November 2021 for use in adult patients with relapsed/refractory multiple myeloma (R/R MM), specifically in those who have been previously treated with one other therapy.-Fineline Info & Tech
