Azacitidine and Etanercept in Treating Patients With Myelodysplastic Syndromes
This phase I/II trial studies how well giving azacitidine together with etanercept works in treating patients with myelodysplastic syndromes (MDS). Drugs used in chemotherapy, such as azacitidine, works in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Chemoprotective drugs, such as etanercept, may protect normal cells from the side effects of chemotherapy

- Frequency of hematologic responses, as defined by International Working Group (IWG) criteria [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]A two-stage Simon design for phase II trials will be followed. The operating characteristics of this design yield a 90% chance of declaring a treatment ineffective if they true response rate is 0.30. If the true response rate is 0.50, there is an 80% chance of reaching the threshold of 13 responses out of 32 patients.
|Study Start Date:||April 2005|
|Primary Completion Date:||October 2008 (Final data collection date for primary outcome measure)|
Experimental: Treatment (chemotherapy, chemoprotection)
Patients receive etanercept SC twice weekly during weeks 1 and 2 and azacitidine SC or IV over 10-40 minutes on days 1-7. Treatment repeats every 28 days for at least 3 courses. Treatment continues in the absence of disease progression or unacceptable toxicity.

I. Determine the frequency of hematologic responses in patients with MDS to 5-aza (azacitidine) plus etanercept.
II. Determine the efficacy of 5-aza combined with etanercept in patients with low or intermediate (int)-1 risk who fail to respond to anti-thymocyte globulin (ATG) plus etanercept and for the purpose of this trial are considered as having progressive or "more advanced" disease.
III. Correlate results of ex vivo/in vitro studies on phenotypic, cytogenetic and functional disease characteristics with in vivo treatment responses, to identify parameters that are associated with a high probability of response.
Patients receive etanercept subcutaneously (SC) twice weekly during weeks 1 and 2 and azacitidine SC or intravenously (IV) over 10-40 minutes on days 1-7. Treatment repeats every 28 days for at least 3 courses. Treatment continues in the absence of disease progression or unacceptable toxicity.
