Trial Outcomes & Findings for Safety and Pharmacokinetics of Alpha-1 MP (Alpha1-proteinase Inhibitor (Human), Modified Process) in Participants With Alpha1-Antitrypsin Deficiency (NCT NCT02870309)

NCT ID: NCT02870309

Last Updated: 2021-10-28

Results Overview

An adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of an investigational product, whether considered related to the medicinal product. TEAEs were defined as any AE occurring after or on the first Alpha-1 MP infusion until the final visit of study.

PRIMARY outcome

Timeframe: Up to Week 12

Population: Safety population included all the participants who received any amount of Alpha-1 MP.

An adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of an investigational product, whether considered related to the medicinal product. TEAEs were defined as any AE occurring after or on the first Alpha-1 MP infusion until the final visit of study.
