The Food and Drug Administration (FDA) has accepted for priority review the New Drug Application (NDA) for Edsivo (celiprolol; Acer Therapeutics) for the treatment of vascular Ehlers-Danlos syndrome (vEDS) in patients with a confirmed type III collagen (COL3A1) mutation.

Vascular EDS is the most severe subtype of Ehlers-Danlos syndrome where patients suffer from life-threatening arterial dissections and ruptures, as well as intestinal and uterine ruptures. In September 2017, the Company announced positive results from a pivotal clinical trial of celiprolol, a β1-andrenoceptor antagonist with partial β2 agonist activity, which confirmed the treatment to be effective in patients with vEDS.
