Primary Outcome Measures :
  1. Annual Rate of the Physiologically Adjusted Lung Density Change [ Time Frame: Baseline, up to Week 104 ]
    Annual rate of the physiologically adjusted lung density change will be measured as the 15th percentile of the lung density measurements (PD15) as assessed by Computed Tomography (CT) densitometry at total lung capacity (TLC). CT lung density at the 15th percentile (PD15) is the threshold below which 15 percentage (%) of the voxels have lower densities and is used as the parameter for estimating the rate of lung density decline. Annual rate of the physiologically adjusted lung density change will be tested in a fixed comparision sequence 1. ARALAST NP 120 mg/kg BW/week group versus (vs) external placebo group, 2. ARALAST NP120 mg/kg BW/week vs 60 mg/kg BW/week, 3. ARALAST NP 60 mg/kg BW/week group vs external placebo group.

Secondary Outcome Measures :
  1. Number of Moderate or Severe Exacerbations of Chronic Obstructive Pulmonary Disease (COPD) [ Time Frame: Baseline, up to Week 104 ]
    COPD exacerbations are defined as an acute worsening of respiratory symptoms that results in additional therapy and will be assessed according to the classification in GOLD criteria (2020) as follows: Moderate (treated with short acting bronchodilators [SABDs] plus antibiotics and/or oral corticosteroids) and Severe (required hospitalizations or a visit to the emergency room).

  2. Annual Rate of Change in Post-Bronchodilator Forced Expiratory Volume in 1 Second (FEV1) [ Time Frame: Baseline, up to Week 104 ]
    Annual rate of change in post-bronchodilator FEV1 will be assessed.

  3. Number of Participants with Treatment-Emergent Adverse Events (TEAE's) [ Time Frame: From Start of the study drug administration up to End of the study (up to Week 105) ]
    An adverse event (AE) is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this IP or medicinal product. A TEAE is defined as any event emerging or manifesting at or after the initiation of treatment with an IP or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the IP or medicinal product. TEAE's will include related, serious adverse events (SAEs), suspected adverse reactions plus adverse reactions of interest, temporally-associated adverse events (AEs) with onset during infusion or within 24 hours following the end of IP infusion, and AEs resulting in changes to infusion dose.

  4. Number of Participants Who Develop Anti-A1PI Antibodies Following Treatment With ARALAST NP [ Time Frame: From Start of the study drug administration up to End of the study (up to Week 105) ]
    Number of participants who develop anti- A1PI antibodies following treatment with ARALAST NP will be assessed.

  5. Plasma Trough Level of Antigenic and Functional A1PI for ARALAST NP at each dose Level [ Time Frame: Pre-dose, Weeks 4, 13, 28, 52, 78, 91, 104, 105 ]
    Plasma trough level of antigenic and functional A1PI for ARALAST NP at each dose level (ARALAST NP 60 mg/kg BW/week, ARALAST NP 120 mg/kg BW/week) will be assessed.

Ages Eligible for Study:   18 Years to 65 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Adults 18 to 65 years of age at the time of screening
  • Diagnosis of A1PI deficiency with endogenous plasma A1PI level less than (<) 11 micromoles(μM) (< 0598 milligram per milliliter [mg/mL]) following 4-week minimum washout from previous last dose of A1PI augmentation therapy The screening plasma A1PI level may be repeated if a participant is determined to have an exclusionary value that maybe due to an inadequate washout of augmentation therapy Participants eligible for enrollment include newly diagnosed, previously untreated, currently treated and currently not on treatment but received treatment in the past
