What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 research study is looking at people with inherited red blood cell disorders, such as hemolytic anemia, to better understand the genetic causes. Researchers will study blood samples from up to 400 participants to identify specific gene changes. The goal is to improve diagnosis and knowledge of these conditions.

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 lead to better genetic testing and diagnosis for people with inherited red blood cell disorders.
What could go wrong
This is an observational study, not testing a treatment. It may not directly improve health outcomes, and results depend on participant enrollment and genetic analysis.

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

Study facts

What this study's own registry entry says, in plain language.

Participants

About 400 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jul 2011

Expected to finish

Jul 2052

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Who is studied

If medical history and review of the laboratory data obtained for clinical care, including CBC/reticulocyte count and review of the blood smear, indicates that the patient has a non-immune hemolytic anemia that may be due to a hemoglobinopathy, a red cell membrane skeleton or enzyme disorder, then the patients and their families will be asked for their participation in the study. The rare patients suspected to have congenital dyserythropoietic anemia will also be eligible for this study.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

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

Inclusion Criteria: 1. Patients who have been diagnosed, by medical history and review of the laboratory data obtained for clinical care, including CBC/reticulocyte count and review of the blood smear, with a hereditary hemolytic anemia, where the genetic etiology is challenging to be identified. 2. Parents and/or grandparents of children that have the above diagnosis. The parents and/or grandparents may or may not have non-immune hemolytic anemia (these will serve as positive or negative inherent controls) Exclusion: 1\) Patients with anemias known to be acquired and not associated with a genetic etiology.
