What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Who Achieved Hematologic Improvement (HI)

    This is a measure of HI in the erythroid, platelet, and neutrophil lineages. Note that HI was observed in the erythroid lineage only, which is defined as a participant who had a >=1.5 g/dL increase in hemoglobin from baseline (pretreatment value must have been <11 g/dL) and who had a relevant reduction of units of red blood cell (RBC) transfusions by an absolute number of >=4 RBC transfusions over 8 weeks as compared with the pretreatment transfusion number in the previous 8 weeks. These criteria were taken from the 2006 International Working Group criteria.

    Measured: 12 months

Secondary outcomes (11)
  1. Number of Participants With Duration of HI

    This is a measure of the duration of HI for those participants who achieved HI. Duration of HI is defined as the time from confirmation of HI response to the date of first documentation of HI relapse or death due to any cause, whichever occurs first.

    Measured: 36 months

  2. Number of Participants Who Achieved Disease Remission

    Disease remission is defined as a participant whose best response to therapy was a complete remission or partial remission. A complete remission is defined as: bone marrow <=5% myeloblasts with normal maturation of all cell lines; persistent dysplasia noted; and peripheral blood hemoglobin >=11 g/dL, platelets >=100 x 10^9/L, neutrophils >=1.0 x 10^9/L, and blasts 0%. Partial remission is defined as: all complete remission criteria if abnormal before treatment, except bone marrow blasts decreased by >=50% over pretreatment, but still >5%; and cellularity and morphology not relevant.

    Measured: 36 months

  3. Duration of Disease Remission

    This is a measure of the duration of overall disease remission only for those participants who achieved an overall remission. Duration of overall remission is defined as the time from first documentation of overall remission to the date of first documentation of disease relapse or death due to any cause, whichever occurs first.

    Measured: 36 months

  4. Number of Participants Who Achieved Transfusion Independence

    This is a measure of transfusion independence, which is defined as a participant with no transfusions for a period of 8 consecutive calendar weeks after first dose. Transfusion independence was to be calculated only for those participants who had documented transfusions during the 8 weeks prior to enrollment.

    Measured: 36 months

  5. Number of Participants With Duration of Transfusion Independence

    This is a measure of the duration of transfusion independence only for those participants who achieved transfusion independence. Duration of transfusion independence is defined as the longest period of time during which a participant requires no transfusions.

    Measured: 36 months

  6. Number of Participants With a Relapse Following HI

    This is a measure of relapse following HI, which is defined as a participant who experiences at least one of the following: >=50% decrease from maximum response levels in granulocytes or platelets; >=1.5 g/dL reduction in hemoglobin; or transfusion dependence.

    Measured: 36 months

  7. Number of Participants With a Relapse Following Overall Remission

    This is a measure of relapse following an overall remission only for participants who experienced either a complete or partial remission. Relapse following an overall remission is defined as a participant who meets any of the following criteria: a return to pretreatment bone marrow blast percentage; decrease of >=50% from maximum remission levels in neutrophils or platelets; reduction in hemoglobin concentration by >=1.5 g/dL from maximum remission levels; or transfusion dependence.

    Measured: 36 months

  8. Number of Participants With Progression-free Survival

    This is a measure of a progression-free survival which is defined as the time from the participant's first dose to the date of disease progression, lost to follow-up or death due to any cause, whichever occurs first.

    Measured: 36 months

  9. Number of Participants With Transformation to Acute Myeloid Leukemia

    This is a measure of transformation to acute myeloid leukemia only for participants who have bone marrow assessments. Transformation to acute myeloid leukemia is defined as the earliest date a participant experiences bone marrow blasts of >=20% after the start of treatment.

    Measured: 36 months

  10. Number of Participants With a Cytogenetic Response

    This is a measure of cytogenic response for participants whose best response to therapy is a either a complete or partial cytogenetic response. A complete cytogenetic response is defined as the disappearance of the chromosomal abnormality without appearance of new ones. A partial cytogenetic response is defined as at least 50% reduction of the chromosomal abnormality.

    Measured: 36 months

  11. Number of Participants With a Marrow Remission

    This is a measure of bone marrow complete remission for participants who experience a remission. Bone marrow complete remission is defined as a bone marrow assessment of <=5% myeloblasts and decrease by >=50% over pretreatment.

    Measured: 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Thymoglobulin®, Rabbit Anti-thymocyte Globulin (rATG) in people with Myelodysplastic Syndrome (MDS), run by Genzyme, a Sanofi Company at 7 sites in 4 countries.

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 9 inclusion and 16 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: stopped early, as of the sponsor's last update on 3 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United Kingdom, Germany, France, Netherlands. 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?

Yes. Results are posted in the registry (first posted 27 Apr 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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.

What does the primary outcome measure?

Number of Participants Who Achieved Hematologic Improvement (HI) (time frame: 12 months). It is what the study was designed to measure, not a finding.

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 3 Apr 2015.
