Effekt og sikkerhed af alfa1-proteinasehæmmer (menneskelig), modificeret proces (alfa-1 MP) hos personer med lungeemfysem på grund af alfa1 antitrypsinmangel (AATD) (SPARTA)

28. september 2026 opdateret af: Grifols Therapeutics LLC

En randomiseret, dobbeltblind, placebokontrolleret undersøgelse til vurdering af effektiviteten og sikkerheden af ​​to dosisregimer (60 mg/kg og 120 mg/kg) af ugentlig intravenøs alfa1-proteinasehæmmer (menneske) hos personer med lungeemfysem på grund af alfa1-antitrypsinmangel

This is a multi-center, randomized, placebo-controlled, double blind clinical study to assess the efficacy and safety of two separate dose regimens of Alpha-1 MP versus placebo for 156 weeks (i.e., 3 years) using computed tomography (CT) of the lungs as the main measure of efficacy. The two Alpha-1 MP doses to be tested are 60 mg/kg and 120 mg/kg administered weekly by IV infusion for 156 weeks. The study consists of an optional pre-screening phase, Screening Phase, a 156-week Treatment Phase, and an End of Study Visit at Week 160.

  • Smoking during the past 12 months or a positive urine cotinine test at screening that is due to smoking. Maybe on Nicotine replacement, including vapor cigarettes.
  • History of anaphylaxis or severe systemic response to any plasma-derived alpha1-PI preparation or other blood product(s).
  • Use of systemic steroids above a stable dose equivalent to 5 mg/day prednisone (i.e., 10 mg every 2 days) within the 5 weeks prior to the Screening Visit (inhaled steroids are not considered systemic steroids) or during the Screening Phase.
