Today, the U.S. Food and Drug Administration approved Rethymic for the treatment of pediatric patients with congenital athymia, a rare immune disorder. Rethymic is the first thymus tissue product approved in the U.S.

“Today’s action marks the first FDA approval of a therapy to treat this very rare and devastating disease in children,” said Peter Marks, M.D., Ph.D., director of the FDA’s Center for Biologics Evaluation and Research.
