Trial Outcomes & Findings for A Study To Assess the Adverse Effects and Change in Condition of OnabotulinumtoxinA X Injection in Adult Participants With Forehead Lines (NCT NCT05152576)
NCT ID: NCT05152576
Last Updated: 2025-07-16
Results Overview
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a casual relationship with this treatment. The investigator assesses the relationship of each event to the use of the study. A serious adverse event (SAE) is an event that results in death, is life threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event, that based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above.
