What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study follows 45 adults with alpha-1 antitrypsin deficiency (a genetic condition that can cause liver damage) to learn how the disease progresses. Researchers will analyze stored blood and liver tissue samples to find biomarkers and understand the molecular pathways involved. The goal is to improve monitoring and eventually guide future treatments.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could identify blood markers to better predict and monitor liver disease in people with alpha-1 antitrypsin deficiency.
What could go wrong
This is an observational study, not a treatment trial. It will not directly test any therapy, and results may take years to translate into clinical practice.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

* Adult patients (≥18 years) with genetically confirmed alpha-1 antitrypsin deficiency (Pi\*ZZ genotype). * Availability of longitudinal clinical follow-up data (minimum 5 years) within the AATD consortium. * At least one documented liver assessment including liver stiffness measurement (LSM) and serum-based fibrosis markers. * Availability of stored serum samples for proteomic analysis. * For translational analyses: availability of liver tissue samples (pediatric or adult) and/or induced pluripotent stem cell (iPSC)-derived hepatocyte-like cells.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patients (≥18 years) with genetically confirmed alpha-1 antitrypsin deficiency (Pi\*ZZ genotype). * Availability of longitudinal clinical follow-up data (minimum 5 years) within the AATD consortium. * At least one documented liver assessment including liver stiffness measurement (LSM) and serum-based fibrosis markers. * Availability of stored serum samples for proteomic analysis. * For translational analyses: availability of liver tissue samples (pediatric or adult) and/or induced pluripotent stem cell (iPSC)-derived hepatocyte-like cells. Exclusion Criteria: * Presence of other chronic liver diseases (e.g., viral hepatitis, autoimmune hepatitis) that may confound fibrosis assessment. * History of liver transplantation prior to study inclusion. * Incomplete clinical, laboratory, or follow-up data. * Poor-quality or insufficient biological samples for proteomic or molecular analyses. * Patients lost to follow-up or with unreliable longitudinal data
