入选标准
- •Be between 18 and 70 years of age, inclusive
- •Had a diagnosis of congenital AATD
- •Had a documented total alpha₁-PI level < 11 µM. If the total alpha₁-PI level had yet to be documented, a blood draw for total alpha₁-PI level was obtained at the Screening Visit
- •Had a post-bronchodilator Forced expiratory volume in 1 second (FEV1) ≥ 30% and < 80% of predicted and FEV1/forced vital capacity (FVC) < 70%
- •If the subject had received alpha₁-PI augmentation therapy of any kind, he/she must have been be willing to discontinue that treatment at the Week 1 (Baseline) Visit and remain off any kind of alpha₁-PI treatment, other than the investigational products for this study, while participating in the study
排除标准
- •Subject had a moderate or severe pulmonary exacerbation during the 4 weeks before the Week 1 (Baseline) Visit
- •History of lung or liver transplant
- •Any lung surgery during the past 2 years (excluding lung biopsy)
- •Liver cirrhosis confirmed by biopsy
- •Elevated liver enzymes (aspartate transaminase [AST], alanine aminotransferase [ALT], and alkaline phosphatase [ALP]) equal to or greater than 2.5 times the upper limit of normal
- •Severe concomitant disease (e.g., congestive heart failure, clinically significant pulmonary fibrosis, malignant disease [with the exception of skin cancers other than melanoma], history of acute hypersensitivity pneumonitis reaction, or current chronic hypersensitivity pneumonitis)
- •Females who were pregnant, breastfeeding or, if of child-bearing potential, unwilling to practice a highly effective method of contraception (oral, injectable or implanted hormonal methods of contraception, placement of an intrauterine device (IUD) or intrauterine system (IUS), condom or occlusive cap with spermicidal foam/gel/film/cream/suppository, male sterilization, or abstinence) throughout the study
- •Known previous infection with or clinical signs and symptoms consistent with current hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency virus (HIV) infection
- •Smoking during the past 6 months or a positive urine cotinine test at the Screening Visit that is due to smoking
- •Participation in another investigational drug study within one month prior to the Week 1 (Baseline) Visit
- •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 4 weeks prior to the Week 1 (Baseline) Visit inhaled steroids are not considered systemic steroids)
- •Use of systemic or aerosolized antibiotics for an exacerbation within the 4 weeks prior to the Week 1 (Baseline) Visit
- •Known selective or severe Immunoglobulin A (IgA) deficiency
结局指标
主要结局
AUC(0-7 Days) Based on Antigenic Content
时间窗: pre-dose, 0, 15 min, 30 min, 1 hour, 2 hours, 4 hours, 8 hours, 1 day, 2 days, 5 days, 7 days post dose
The primary PK objective of this study was to demonstrate the bioequivalence of Liquid Alpha₁-PI 60 mg/kg to Prolastin-C 60 mg/kg, as measured by AUC from 0 to 7 days (AUC0-7days) using an antigenic content assay of alpha₁-PI, at approximate steady state in subjects with AATD.
次要结局
- AUC(0-7 Days) Based on Functional Activity(pre-dose, 0, 15 min, 30 min, 1 hour, 2 hours, 4 hours, 8 hours, 1 day, 2 days, 5 days, 7 days post dose)
- Number of Subjects With Immunogenicity Response(Weeks 1, 9, 17, and 20)
