A Study of TSRA-196 in Adults With PiZZ Alpha-1 Antitrypsin Deficiency (AATD)

This is a Phase 1/2, open-label, multi-center, dose escalation (Part 1), dose expansion (Part 2), and single repeat dose (Part 3) study to evaluate the safety, tolerability, efficacy, and PK/PD parameters of TSRA-196 in adults with the PiZZ genotype who have lung and/or liver disease associated with severe alpha-1 antitrypsin deficiency (AATD)

AATD-Liver Scan Study

The goal of this study is to provide liver stiffness screenings (FibroScans) to patients with Alpha-1 Antitrypsin Deficiency for the following purposes: To evaluate the prevalence of elevated liver stiffness among homozygous and heterozygous individuals who carry mutations in the SERPINA1 gene. To assess whether the coexistence of metabolic or environmental cofactors, such as obesity, diabetes, alcohol use, or hepatic steatosis, modifies the risk of liver fibrosis among those with alpha 1 antitrypsin deficiency.

A Study of the Safety and Efficacy of Prime Editing (PM647a) in Participants With Alpha-1 Antitrypsin Deficiency

The purpose of this study is to evaluate the safety, tolerability, biological activity, and initial efficacy of PM647a, an investigational Prime Editing therapy, in adults and adolescents with Alpha-1 Antitrypsin Deficiency (AATD). AATD is caused by a mutation (change) in a gene called SERPINA1 that prevents the cells in your liver from producing a functional protein (alpha-1 anti-trypsin; AAT) that helps protect your lung tissue. PM647a is designed to precisely correct the prevalent disease-causing mutation (SERPINA1 Pi\*Z (E342K)) with the goal of restoring functional AAT. This is the first study of PM647a in humans. Participants will receive a single intravenous (IV) infusion of PM647a and will be monitored closely to evaluate safety, how the body responds to treatment, changes in AAT protein levels, and whether treatment may improve signs and symptoms of AATD.

A Trial Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of CTX460 in Adults With Emphysema Associated With Severe Alpha-1 Antitrypsin Deficiency (AATD)

A Study of CTX460 in Adults with Emphysema Associated with Severe Alpha-1 Antitrypsin Deficiency (AATD).

Study of YOLT-202 in the Treatment of Alpha-1 Antitrypsin Deficiency (AATD)

This is a single-arm, open-label, single-dose, dose-escalation exploratory study to evaluate the safety and tolerability of a single dose of YOLT-202 in patients with AATD and determine the optimal biologically active dose (OBD) of YOLT-202.
