Trial summary

Approximately 40% of the patients with myelodysplastic syndrome (MDS) die as a consequence of their cytopenia. As in aplastic anemia, the cytopenia of MDS may be partly due to cytotoxic T cell activity. Immunosuppressive therapy may therefore reverse the cytopenia. Read more about this study

About this study

Approximately 40% of the patients with myelodysplastic syndrome (MDS) die as a consequence of their cytopenia. As in aplastic anemia, the cytopenia of MDS may be partly due to cytotoxic T cell activity. Immunosuppressive therapy may therefore reverse the cytopenia. In a phase II pilot study of anti-thymocyte globin (ATG) to treat myelodysplastic syndrome (MDS); 41% of patients (61% of patients with refractory anemia) have responded in terms of transfusion independence. Recently, Jonasova et al [32] reported a 82% substantial hematological response rate in 18 patients with MDS of the refractory anemia (RA) subtype treated with cyclosporine alone. Just over 50% of the patients in this series had MDS of the hypocellular type. Cyclosporine alone if indeed efficacious would be a powerful therapeutic option that could be readily used by hematologists in the community to treat patients with MDS. This efficacy needs to be proven in a larger study which includes patients with the other subtypes of MDS and more patients with the non-hypocellular forms of MDS (which constitute approximately 70% of the cases in the community). As MDS is a heterogeneous group of disorders, a randomized comparison with the other immunomodulating intervention of proven benefit, ATG, is appropriate. In this randomized study patients with MDS will receive either ATG alone or cyclosporine alone.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Antithymocyte globulin and Cyclosporine in people with Hematologic Diseases and Myelodysplastic Syndromes, run by National Institutes of Health Clinical Center (CC) at 1 site in United States.

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

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?
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.
