Clinical Trial: Anti-Thymocyte Globulin and Etanercept in Treating Patients With Myelodysplastic Syndromes

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Therapy of Early Stage Myelodysplastic Syndrome (MDS) With ATG and Etanercept

Brief Summary:

RATIONALE: Biological therapies, such as anti-thymocyte globulin and etanercept, may stimulate the immune system in different ways and stop cancer cells from growing. Giving anti-thymocyte globulin together with etanercept may kill more cancer cells.

PURPOSE: This phase II trial is studying how well giving anti-thymocyte globulin together with etanercept works in treating patients with myelodysplastic syndromes.


Detailed Summary:

OBJECTIVES:

  • Determine the response rate in patients with low- or intermediate-1-risk myelodysplastic syndromes treated with anti-thymocyte globulin and etanercept.
  • Correlate ex vivo and in vitro phenotypic, cytogenetic, and functional disease characteristics with in vivo response in patients treated with this regimen.
  • Determine parameters that are associated with a high probability of response or non-response in patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive anti-thymocyte globulin IV over 8 hours on days 1-4. Patients also receive etanercept subcutaneously on days 8, 11, 15, and 18. Treatment with etanercept repeats every 28 days for at least 2 courses. Patients exhibiting hematologic improvement after course 2 may receive up to 2 additional courses of etanercept in the absence of disease progression or unacceptable toxicity. Patients with unresponsive disease or disease progression after course 2 are removed from the study and offered other treatment.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study within 3 years.
