Trial Outcomes & Findings for A Study of Single and Multiple Doses of ALXN1210 in Healthy, Adult Japanese Participants (NCT NCT05288816)

NCT ID: NCT05288816

Last Updated: 2024-02-05

Results Overview

An adverse event (AE) was defined as any unfavorable and unintended sign (for example, including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product or procedure, whether or not considered related to the medicinal product or procedure, which occurred during the course of the clinical study. TEAEs were defined as AEs that occurred on or after the date and time of study drug administration, or those that first occurred before dosing but worsened in frequency or severity after study drug administration. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.

PRIMARY outcome

Timeframe: Cohort 1: Baseline up to Day 120; Cohort 2: Baseline up to Day 140; Cohort 3: Baseline up to Day 298

Population: The safety population consisted of all participants who received at least 1 dose of study drug.

An adverse event (AE) was defined as any unfavorable and unintended sign (for example, including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product or procedure, whether or not considered related to the medicinal product or procedure, which occurred during the course of the clinical study.
