Clinical Trial Summary

This is a prospective, Phase 3, randomized, double-blind, placebo-controlled efficacy study to evaluate celiprolol in patients genetically confirmed as COL3A1-positive vEDS using a decentralized clinical trial design.

Description:

This is a prospective, Phase 3, randomized, double-blind, placebo-controlled efficacy study to evaluate celiprolol in patients genetically confirmed as COL3A1-positive vEDS using a decentralized clinical trial design. The double-blind portion of this study is intended to end if statistical significance is reached at the interim analysis (accrual of 28 vEDS-related events requiring medical attention; estimated to take 24 months) or after accrual of 46 vEDS related clinical events requiring medical attention (estimated to take 40 months). A total of approximately 150 patients who meet all the inclusion and none of the exclusion criteria will be enrolled and randomized 2:1 to receive either celiprolol or placebo, respectively. Following the double-blind treatment period or occurrence of vEDS-related clinical event, patients have the option to participate in an open label extension period.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to first occurrence of a vEDS-related clinical event requiring medical attention: Fatal/nonfatal cardiac or arterial events [including dissection or rupture], uterine rupture, intestinal rupture, and/or unexplained sudden death		Over the double-blind period (estimated to be 40 months)
Secondary	Number and proportion of patients reporting a vEDS related clinical event requiring medical attention: Fatal/nonfatal cardiac or arterial events [including dissection or rupture], uterine rupture, intestinal rupture, and/or unexplained sudden death		Over the double-blind period (estimated to be 40 months)
Secondary	Number and percentage of patients with adverse events	An Adverse Event (AE) is defined as any untoward medical occurrence associated with the use of the investigational product in humans, whether or not considered related to investigational product. An AE can be any unfavorable and unintended sign (e.g., an abnormal laboratory finding), symptom, or disease temporally associated with any use of the investigational product, without any judgment about causality and irrespective of route of administration, formulation, or dose, including an overdose.	Over the double-blind period (estimated to be 40 months)
Secondary	Number and percentage of Serious Adverse Events (SAE)	An AE is considered "serious" if, in the view of either the investigator or Acer, it results in any of the following outcomes: Death, Is immediately life threatening; Requires in-patient hospitalization or prolongation of existing hospitalization; Results in persistent or significant disability or incapacity; Results in a congenital abnormality or birth defect; Is an important medical event that may jeopardize the subject or may require medical intervention to prevent one of the outcomes listed above.	Over the double-blind period (estimated to be 40 months)
Secondary	Number and percentage of patient deaths		Over the double-blind period (estimated to be 40 months)
Secondary	Number and percentage of patient discontinuations	Discontinuation or withdrawal from the study	Over the double-blind period (estimated to be 40 months)
