Active clinical trials for "Alpha 1-Antitrypsin Deficiency"

This study will evaluate the efficacy, safety and pharmacokinetics (PK) of VX-814 in PiZZ subjects.

This study is composed of two parts. Part A: will test single doses of ZF874 in a double-blind, randomised, placebo-controlled and dose-escalating design (except Group 7, which will be open-label and without placebo). Up to 7 groups of 6-8 healthy volunteers will receive an oral dose of ZF874 or matching placebo (6 active: 2 placebo in Groups 1-6; 6 active in Group 7). The dosing of the first 2 subjects (1 active and 1 placebo) will take place before dosing of the remainder of the group in Groups 1-6, with morning doses given in the fasted state. The dose will be escalated only if the safety and tolerability of the previous highest dose are acceptable, and the plasma concentrations of ZF874 are predicted to remain below the toxicokinetic exposure limit, as determined by the Safety Review Group. Group 7 will consist of 6 subjects, all of whom will receive ZF874 after consuming a standard high-fat breakfast. Dosing of the first 2 subjects before the rest of the group is not required in Group 7, as 6 subjects have already safely received ZF874 at this dose in Group 3 and 12 subjects have already safely received higher doses in Groups 4 and 5. The dose selected for Part A, Group 7 was chosen as the dose has previously been given to subjects fasted in Group 3, and it was safe and well tolerated, allowing for comparison for the food effect, and higher doses have been tested in Part A with no safety concerns. Part B: Multiple Ascending Doses in subjects carrying at least one Z mutated alpha-1-antitrypsin (Z-A1AT) allele (PiXZ subjects): Up to 4 groups of up to 5 PiXZ subjects will be enrolled in Part B (Groups 1-4). In Group 1, up to 4 subjects will receive twice daily doses of either ZF874 or placebo on 28 consecutive days. The dose level (dose and dose regimen) selected for Part B Group 1 will be based on review of the available results from Part A. In Groups 2-4, up to 5 PiXZ subjects will receive ZF874 twice daily by mouth for 28 days; no subjects will receive placebo. The dose for Groups 2 - 4 will not exceed the doses already given in Part A.

The primary objective is to determine if the medication Carbamazepine, can be used as a therapy for patients with severe liver disease due to Alpha-1-Antitrypsin Deficiency .

The purpose of this study is to conduct a pilot study to evaluate the safety and efficacy of weekly administration of Alpha1-Proteinase Inhibitor (A1PI) augmentation therapy in subjects with A1PI deficiency and emphysema/ chronic obstructive pulmonary disease (COPD).

The purpose of this study is to evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Subcutaneously Administered ALN-AAT in Healthy Adult Subjects and Patients with ZZ Type Alpha-1 Antitrypsin Deficiency Liver Disease.

This is a multicenter, randomized, partial-blinded, five-arm, placebo-controlled study of human plasma-derived alpha1-proteinase inhibitor (alpha1-PI) in children (ages 6-11 years old) and teens/adults (ages 12-35 years old) with new onset Type 1 Diabetes Mellitus (T1DM). Currently enrolling ages 12-35 only. Once 25 patients are randomized and data is reviewed enrollment will be opened to the child cohort. The purpose of this study is to evaluate the safety and efficacy of four dosing regimens of human plasma-derived alpha1-PI in T1DM.

The purpose of this study is to evaluate the safety and tolerability of single or multiple doses of ALN-AAT02. The study will be conducted in 2 sequential phases in which Part A will be a single-ascending dose (SAD) phase in healthy participants, and Part B will be a multiple-ascending dose (MAD) phase in participants with ZZ type alpha-1 antitrypsin deficiency (PiZZ) and biopsy-proven alpha-1 antitrypsin (AAT) deficiency-associated liver disease.

The purpose of the study is to determine the safety and tolerability of escalating doses of ARC-AAT and to evaluate the pharmacokinetics of ARC-AAT and the effect of ARC-AAT on circulating levels of alpha-1 antitrypsin (AAT). The study will consist of two parts, Part A (conducted in healthy volunteers) and Part B (conducted in AATD patients) at up to 9 escalating dose levels with 6 participants per dose level.

The primary objectives of this Phase 4, open label, prospective U.S. surveillance study are to evaluate the health outcomes of Alpha 1-Antitrypsin (AAT)-deficient subjects who are initiating treatment with ARALAST on patient-related outcomes (PRO), i.e., health-related quality of life (HRQoL), healthcare resource utilization (HCRU), and various laboratory analyses to evaluate the safety of long-term administration of ARALAST. Up to 120 subjects will be enrolled and assessed for HRQoL and HCRU at baseline and every 6-months thereafter, for 2 years. A subset of subjects will be enrolled into the blood draw portion of the study, which will also include assessments of antibodies to ARALAST, and chemistry panel. Subjects will be treated according to the prescribing (attending) physician's instructions based on the prescribing information given in the ARALAST package insert.

Patients with advanced heterogeneous emphysema due to alpha1 antitrypsin deficiency might benefit from endoscopic implantation of intrabronchial valves.
