Study Summary

This trial will test a new treatment for AATD that is given as a single infusion, then once a week for 8 weeks. The goal is to see if it is safe and tolerated.

Who is the study for?
This trial is for individuals with Alpha1-Antitrypsin Deficiency (AATD) who have low serum AAT levels and specific lung function measurements. Participants can be new or current on Alpha1-PI therapy but must stop it before the study starts. Pregnant women, those not using effective contraception, people with severe allergies to plasma-derived treatments, recent lung surgery patients, or those with certain health conditions are excluded.Check my eligibility
What is being tested?
The study tests two doses of a medication called Alpha-1 15%, given as a subcutaneous infusion in participants with AATD. The first dose is administered once and then weekly over eight weeks to evaluate safety and how the body processes the drug.See study design
What are the potential side effects?
While specific side effects aren't listed here, common ones for similar treatments may include injection site reactions, possible allergic responses especially in those sensitive to plasma products, headaches, fatigue, and flu-like symptoms.

Trial Design

6Treatment groups
Experimental Treatment
Group I: Cohort 2: Treatment Period 2 (Alpha-1 15%, 180 mg/kg)Experimental Treatment1 Intervention
Following treatment period 1 and single-dose data evaluation phase, participants in Cohort 2 will enter treatment period 2 (Repeat-Dose) and will receive Alpha-1 15% 180 mg/kg, for 8 weekly SC infusions.
Group II: Cohort 2: Treatment Period 1 (Alpha-1 15%, 180 mg/kg)Experimental Treatment1 Intervention
Participants will receive Alpha-1 15% 180 mg/kg, single weekly SC infusion in treatment-period 1 (Single-Dose) at Week 1.
Group III: Cohort 2: Single-Dose Data Evaluation Period (Liquid Alpha1-Proteinase Inhibitor 120 mg/kg)Experimental Treatment1 Intervention
Following treatment period 1, participants in Cohort 2 will enter 21 days of washout/serial pharmacokinetic (PK) phase and then the single-dose data evaluation phase. During the single-dose data evaluation phase, Liquid Alpha1-PI 120 mg/kg, weekly IV Infusions will be administered from intravenous-dose Week 1 (single-dose Week 5) for up to Week 78, with the last IV dose given 1 week prior to the first repeat Alpha-1 15% SC dose.
Group IV: Cohort 1: Treatment Period 2 (Alpha-1 15%, 72 mg/kg)Experimental Treatment1 Intervention
Following treatment period 1 and single-dose data evaluation period, participants in Cohort 1 will enter treatment period 2 (Repeat-Dose) and will receive Alpha-1 15% 72 mg/kg, for 8 weekly SC infusions.
Group V: Cohort 1: Treatment Period 1 (Alpha-1 15%, 72 mg/kg)Experimental Treatment1 Intervention
Participants will receive Alpha-1 15% 72 mg/kg, single weekly subcutaneous (SC) infusion in treatment-period 1 (Single-Dose) at Week 1.
Group VI: Cohort 1: Single-Dose Data Evaluation Period (Liquid Alpha 1-Proteinase Inhibitor 60 mg/kg)Experimental Treatment1 Intervention
Following treatment period 1, participants in Cohort 1 will enter 21 days of washout/serial pharmacokinetic (PK) phase and then the single-dose data evaluation period. During the single-dose data evaluation phase, Liquid Alpha1- Proteinase Inhibitor (PI) 60 mg/kg, weekly intravenous (IV) Infusions will be administered from intravenous-dose Week 1 (single-dose Week 5) for up to Week 78, with the last IV dose given 1 week prior to the first repeat Alpha-1 15% SC dose.

What prior research has been done regarding Alpha-1 15%?

"Alpha-1 15% was initially researched in 2013 at Clinic Dr.G Curteanu Oradea. 25 studies have been finished since then, with 5 of those actively enrolling new participants - primarily from sites located in Gainesville, Florida."

Answered by AI

Are there any restrictions that prevent me from participating in this experiment?

"This clinical experiment is attempting to register 16 individuals with alpha1-antitrypsin deficiency aged between 18 and 70. Candidates should possess a ZZ, SZ, Z(null), (null)(null), S(null) or "at-risk" alleles combination of AATD as well as be off any kind of Alpha1-PI treatment other than the IPs for this study at baseline. Furthermore, their post bronchodilator FEV1/FVC ratio must be lower than 70% while also being higher than 30%."

Answered by AI

Is there currently an enrollment window open for this clinical investigation?

"Affirmative, according to clinicaltrials.gov this investigation is actively recruiting partakers. This trial was first advertised on August 13th 2021 and most recently revised on August 15th 2022; it seeks 16 participants across 6 locations."

Answered by AI

Has there ever been a similar trial of this magnitude conducted before?

"Alpha-1 15% has been subjected to clinical research since 2013, beginning with a Grifols Therapeutics LLC sponsored trial of 339 participants. After achieving Phase 3 drug approval in the wake of that first study and 5 live trials across 34 cities and 17 countries are now being conducted."
