Brief Summary:
The purpose of AROAAT2001 (SEQUOIA) is to evaluate the safety, tolerability and effect on liver histologic parameters with administration of the investigational product, ARO-AAT, in participants with alpha-1 antitrypsin deficiency (AATD). Participants will receive multiple subcutaneous doses of ARO-AAT.

Condition or disease Intervention/treatment Phase
Alpha 1-Antitrypsin Deficiency Drug: ARO-AAT Injection Other: Placebo Phase 2 Phase 3

Detailed Description:
In Part A, participants will be enrolled to receive multiple doses of ARO-AAT or placebo at varying dose levels. Once Part A is complete, a single dose level for Part B will be selected based on safety and pharmacodynamic parameters from Part A. Patients enrolled into Part A will roll over to the Part B dose level or continue to receive placebo.

Primary Outcome Measures :
  1. Part A: Percentage Change From Baseline in Soluble Liver Z-Alpha-1 Antitrypsin (Z-AAT), insoluble liver Z-AAT Levels at Day 113 [ Time Frame: Baseline, Day 113 ]
  2. Part A: Percentage Change From Baseline in Serum AAT Levels at Day 113 [ Time Frame: Baseline, Day 113 ]
  3. Part A:Number of Participants with Adverse Events (AEs) Possibly or Probably Related to Treatment [ Time Frame: Up to Day 113 ]
  4. Part B:Number of Participants Achieving a 2-Point Improvement in a Histologic Grading Scale of AATD Associated Liver Disease AND No Worsening of Liver Fibrosis Based on Ishak Score [ Time Frame: End of Study Biopsy (84 days +/- 14 days after last Part B dose) ]

Secondary Outcome Measures :
  1. Part B: Change from Baseline Over Time in a Histologic Grading Scale of AATD Associated Liver Disease [ Time Frame: Baseline, End of Study Biopsy (84 days +/- 14 days after last Part B dose) ]
  2. Part B: Number of Participants with Ishak Fibrosis Stage 1 or Greater Achieving at Least a 1-Stage Improvement [ Time Frame: End of Study Biopsy (84 days +/- 14 days after last Part B dose) ]
  3. Part B: Change from Baseline Over Time in Ishak Fibrosis Score [ Time Frame: Baseline, End of Study Biopsy (84 days +/- 14 days after last Part B dose) ]
  4. Part B: Number of Participants with AEs Possibly or Probably Related to Treatment [ Time Frame: Up Through End of Study Biopsy (84 days +/- 14 days after last Part B dose) ]
