Argenx Buys Priority Review Voucher from Bluebird for $102 Mil.
Argenx has agreed to purchase a Priority Review Voucher from Bluebird Bio for $102 million, which Argenx plans to use for a planned BLA for efgartigimod, its first-in-class neonatal Fc receptor blocker that is being studied in autoimmune diseases. A year ago, FDA approved Argenx’s Vyvgart (intravenous efgartigimod) for treating generalized myasthenia gravis in adults who are anti-AChR antibody positive.
The company says it has demonstrated proof-of-concept with efgartigimod in four autoimmune diseases, and it is planning to be active in 15 disease targets by 2025. “With a priority review voucher available, we hope to expedite the approval process for one of our current or future indications to more quickly reach the patients who are in serious need of a new treatment option,” it says.
