Ascidian Therapeutics, Inc50 enrolled

Overview

This is an observational prescreening study. Individuals who are eligible for prescreening will undergo testing procedures that may be used to determine eligibility in ACDN-01 clinical trials.

The prescreening process will be used to help determine the initial eligibility and interest of potential participants in ACDN-01 clinical trials by conducting assessments of key eligibility criteria before the clinical trial screening procedures are performed.
