Summary
- This summary is based on the review of one systematic review(s)/meta-analysis(es). [1]
- Alpha-1 MP (alpha(1)-proteinase inhibitor, modified process) demonstrated stable pulmonary function in Japanese patients with alpha(1)-antitrypsin deficiency (AATD) over approximately four years, with no changes in forced expiratory volume in 1 second (FEV(1)) or forced vital capacity (FVC).
- The average trough level (C(min)) of Alpha-1 MP was maintained at 55.73 (4.99) mg/dL throughout the study period of 213 weeks.
- Among the four patients, 54 treatment-emergent adverse events (TEAEs) were reported, with 96.3% classified as mild; five serious adverse events (SAEs) were reported in two patients, none of which were related to the treatment.
- Three mild TEAEs were deemed potentially related to Alpha-1 MP, with no clinically significant findings in COPD exacerbations, laboratory parameters, or vital signs.
- The study focused on Japanese patients with alpha(1)-antitrypsin deficiency (AATD) and reported that long-term weekly intravenous infusions of 60 mg/kg Alpha-1 MP were generally safe and well-tolerated in this population.
