Trial summary

Diamond Blackfan anemia (DBA) is a condition in which the bone marrow is underdeveloped. DBA is considered a congenital disease, meaning patients are born with it. In DBA there is a lack of cells that give rise to red blood cells. Read more about this study

About this study

Official title: Treatment of Diamond Blackfan Anemia With Antithymocyte Globulin and Cyclosporine A

Diamond Blackfan anemia (DBA) is a condition in which the bone marrow is underdeveloped. DBA is considered a congenital disease, meaning patients are born with it. In DBA there is a lack of cells that give rise to red blood cells. The other elements produced in the bone marrow, such as white blood cells and platelets, are normal.

Standard treatments used for this disorder such as steroids and bone marrow transplants are associated with failure, relapse, side-effects, increased morbidity, and even death. Two drugs, antithymocyte globulin (ATG) and cyclosporin have been used to treat DBA, but have only provided occasional responses. No study has ever combined these two drugs for the treatment of DBA.

This study is designed to explore the combined use of ATG and cyclosporine as a rational approach to the treatment of DBA.

Read the detailed description

Diamond Blackfan anemia (DBA) is a constitutional pure red cell aplasia of unknown etiology. There is laboratory evidence for an immune mechanism and most patients respond to corticosteroids. However the relapse and failure rate are high, and corticosteroids are associated with many short and long term side effects. Patients who do not respond or who do not tolerate corticosteriods require lifelong red blood cell transfusion and iron chelation therapy. Allogeneic bone marrow transplantation is an option for those with a related histocompatible donor, but this procedure is associated with high mortality and morbidity. Other therapies have been tried without general success. Occasional responses to either ATG or cyclosporine have been reported, but no study has used both ATG and cyclosporine. In other blood/bone marrow disorders of immune etiology these drugs have synergistic effects. We propose a Phase II study to explore the combined use of ATG and cyclosporine as a rational approach to the treatment of Diamond Blackfan anemia.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Antithymocyte globulin and Cyclosporine in people with Fanconi's Anemia and Hematologic Disease, run by National Heart, Lung, and Blood Institute (NHLBI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00001749, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
