Medical use

Celiprolol is believed to provide clinical benefit for people with vascular Ehlers–Danlos syndrome by promoting normal collagen synthesis in the blood vessels, and by shifting the pressure load away from the vessels most prone to dissection and rupture.^[2] In 2019, a new drug application (NDA) for celiprolol was denied by the U.S. Food and Drug Administration (FDA), instead calling for an “adequate and well-controlled” trial to determine whether celiprolol reduced the risk of clinical events in patients with vEDS.^[3] In June 2022, Acer Therapeutics Inc. sponsored "Clinical Trial to Compare the Efficacy of Celiprolol to Placebo in Patients With Vascular Ehlers-Danlos Syndrome (DiSCOVER)".^[4]
