About this study

Official title: Mechanism and Response of Thymoglobulin in Patients With Myelodysplastic Syndrome (MDS)

Myelodysplastic syndrome (MDS) is a rare, potentially serious bone marrow disease. Currently available treatments for MDS have been only somewhat beneficial. The purpose of this study is to determine the effects of the medication antithymocyte globulin (ATG) in adults with MDS and to determine which individuals with MDS are most likely to benefit from treatment with ATG.

Read the detailed description

In people with MDS, the bone marrow stops making healthy blood cells and instead produces poorly functioning, malformed, and immature blood cells. This can lead to anemia resulting from too few healthy red blood cells, infection resulting from too few healthy white blood cells, and bleeding resulting from too few healthy platelets. The exact cause of MDS remains unknown, but it may be caused by abnormal autoimmune activity in which activated T cells, a type of white blood cell, prevent normal bone marrow production. ATG, a medication that inhibits immune function, can restore normal blood production in some people with MDS, but it is not known how this happens and why it does not happen in all MDS patients. The purpose of this study is to examine the effects of ATG in adults with MDS and to determine which individuals with MDS are most likely to benefit from treatment with ATG.

Based on disease severity and likely disease progression, participants will be separated into either a high-risk group or a low-risk group. Participants will be hospitalized for a 4-day period during which they will receive daily infusions of ATG. Oral prednisone will be given 2 days before hospitalization, throughout hospitalization, and then for 14 days after hospitalization to limit the side effects of ATG. Antihistamines and acetaminophen will also be given during hospitalization to reduce the chances of an allergic reaction to ATG. After discharge, all participants will attend monthly study visits that will include blood collection, review of disease symptoms, and evaluation of medication response. At Week 16, participants in the high-risk group will undergo additional blood collection, a bone marrow biopsy, and a thorough evaluation of disease progression and the effects of MDS on daily living abilities. Participants in the low-risk group will undergo these same procedures at Week 24. Follow-up for all participants may last up to 2 years.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Antithymocyte globulin (ATG)Drug

    ATG 2.5 mg/kg/day via IV will be given for 4 doses. Each participant will receive only one cycle of therapy. The daily infusion will be administered over at least 6 hours and slowed as necessary to minimize infusion-related symptoms.

  • PrednisoneDrug

    All participants will be pre-treated with prednisone (1 mg/kg/day by mouth) 2 days prior to the first ATG does and continuing for 14 days after the final dose to prevent serum sickness

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Antithymocyte globulin (ATG) and Prednisone in people with Myelodysplastic Syndrome, run by Office of Rare Diseases (ORD) at 4 sites 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 12 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: status not confirmed, as of the sponsor's last update on 2 Jun 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Bone marrow response and hematologic improvement (time frame: Measured at Week 16 or 24). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00466843, which also lists 4 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 2 Jun 2009.
