A Study of RYMPHYSIA for Alpha1-Proteinase Inhibitor (A1PI) Therapy in Adults With A1PI Deficiency and Chronic Obstructive Pulmonary Disease (COPD)-Emphysema

NCT05466747

Phase 4 Withdrawn Takeda
RandomizedParallel-groupOpen-labelTreatment

Summary

The main purpose of this study is to evaluate the efficacy of RYMPHYSIA \[Alpha1-Proteinase Inhibitor (Human)\] compared to another available alpha-1 proteinase Inhibitor (A1PI) in adults with A1PI deficiency and COPD-emphysema. In Part A of the study, participants will be randomly assigned to receive either RYMPHYSIA or another available A1PI for 104 weeks. Participants who were randomized to another available A1PI will enter a 2-week follow-up period after the treatment phase is completed; participants who were randomized to RYMPHYSIA will enter Part B. In Part B, participants will be randomly assigned to one of two groups and will receive either the same dose of RYMPHYSIA as in Part A or a different dose for an additional 104 weeks, followed by a 2-week follow-up period.
