NCT ID NCT06941389

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 Results may not be published yet.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.

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 large study will follow 480 children with sickle cell disease to compare two treatment approaches: a stem cell transplant from a matched family donor versus standard disease-modifying therapies. The goal is to see which option leads to better quality of life and thinking skills over three years. By tracking both groups, researchers hope to provide clear information to help families and doctors make informed treatment decisions.

What this could mean

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

Active substance
matched related donor hematopoietic stem cell transplantation (MRD HCT) and non-transplant disease-modifying therapies (NT-DMT)
What this could lead to
If successful, this study could help families and doctors choose the best treatment for children with sickle cell disease by comparing long-term quality of life and thinking abilities.
What could go wrong
This is an observational study, not a controlled trial, so results may be influenced by factors like patient choice. It will take years to complete and may not provide clear answers for every child.

Who can take part

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

Who is studied

The WeDecide study includes 480 pediatric patients with sickle cell disease (SCD) from two sub-studies: Project Sickle Cure (PSC), focusing on patients receiving transplant through the Sickle Cell Transplant Advocacy Research Alliance (STAR), and the Globin Research Network for Data and Discovery (GRNDaD), a registry of patients on non-transplant disease-modifying therapies (NT-DMT) run by the National Association of Sickle Cell Centers (NASCC). MRD HCT Group: 160 children receiving matched related donor hematopoietic stem cell transplantation (MRD HCT) will be assessed before and at multiple post-transplant time points to evaluate long-term effects. NT-DMT Group: 320 children receiving non-transplant disease-modifying therapies (NT-DMT) will be assessed at study start and annually for three years to track treatment effects.

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

Inclusion Criteria: * Pediatric patients aged between 3 and 20.9 years. * Children diagnosed with sickle cell Anemia (HB SS or HBSB0 Thalassemia) * For the MRD HCT group, children who are candidates for matched related donor hematopoietic stem cell transplantation (MRD HCT). * For the NT-DMT group, children who are receiving non-transplant disease-modifying therapies (NT-DMT) for SCD. * Participants (or their guardians) must provide informed consent to be part of the study. * Participants must be willing to undergo the necessary assessments and follow-up visits over the 3-year study period. Exclusion Criteria: * Children younger than 3 years or older than 20.9 years. * Children who do not have sickle cell anemia or related conditions. * For the MRD HCT group, children who are not eligible for the transplant or do not have a matched related donor. * Children who are currently enrolled in other clinical trials that might interfere with the WeDecide study. * Children who are unable to adhere to the study protocol or follow-up requirements.
