• Participant has known alpha 1-antitrypsin deficiency (α1-antitrypsin deficiency).
• Participant is pregnant or nursing. NOTE: Participants who agree to stop nursing may be considered for inclusion at the discretion of the Investigator.
• Participants of child-bearing potential must agree to use medically acceptable contraceptive measures to prevent pregnancy. All participants of childbearing potential (defined as sexually mature participants who have had menses within the preceding 24 months and have not undergone permanent sterilization methods such as hysterectomy, bilateral oophorectomy, bilateral salpingectomy, etc.) must have a negative serum pregnancy test performed locally at screening. Participants of childbearing potential must agree not to attempt to become pregnant or undergo in vitro fertilization. If participating in sexual activity that could lead to pregnancy, participants must use 2 reliable methods (1 per partner is acceptable) of contraception simultaneously while receiving protocol-specified medication and during the study follow-up period. Participants participating in sexual activity must agree to use, or for their partner to use highly effective birth control methods (those with a failure rate of less than 1% per year when used consistently and correctly) until they have completed the study (after the Day 90 visit). Such methods include: * Combined (estrogen and progesterone containing) hormonal oral, intravaginal, or transdermal contraception associated with the inhibition of ovulation * Progesterone-only oral, injectable, or implantable hormonal contraception associated with the inhibition of ovulation * Intrauterine device (IUD) * Intrauterine hormone-releasing system (IUS) * Bilateral tubal occlusion * Vasectomized partner * Sexual abstinence Participants who are not of reproductive potential (who have been postmenopausal for more than 24 consecutive months or have undergone hysterectomy, bilateral oophorectomy) are not required to use contraception. Participants are prohibited from sperm donation. NOTE: A negative serum pregnancy test will be documented during screening if a participant is of child-bearing potential.
• Participant is currently participating in or has participated in a study using an investigational device or drug or received an investigational drug or investigational use of a licensed drug within 30 days prior to screening.
• Participant does not have sufficient venous access for infusion of study treatment or blood sampling.
• Participant is unable or unwilling to comply with protocol requirements, including assessments, tests, and follow-up visits.
• Participant has any other medical condition which in the opinion of the Investigator will make participation medically unsafe or interfere with the study results.
