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 Results may not be published yet.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

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.

Summary

This registry follows people with recessive dystrophic epidermolysis bullosa (RDEB) who have been treated with prademagene zamikeracel, a gene therapy made from their own skin cells and surgically applied to wounds. The study monitors long-term safety and wound healing durability for up to 15 years after treatment. Participants are assessed annually, either remotely or in person, to track side effects, malignancies, and how well wounds heal over time.

What this could mean

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

Active substance
a gene therapy made from the patient's own skin cells, surgically applied to wounds
What this could lead to
If successful, this registry could confirm that prademagene zamikeracel provides durable wound healing and a favorable long-term safety profile for people with RDEB.
What could go wrong
This is an observational registry, not a controlled trial, so it cannot prove cause and effect. Long-term risks, including malignancies, are still being evaluated.
