Non-Metastatic Ewings Sarcoma clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Prognostic Value of a Positive RT-PCR Test in Patients With Ewing Sarcoma

Start date: March 12, 2004
Phase:
Study type: Observational

This study will determine whether the results of a test called reverse transcriptase-polymerase chain reaction (RT-PCR) correlate with clinical outcomes in patients with Ewing sarcoma, and if they can be used to help identify patients at high risk for metastasis (spread of the cancer beyond the original site). This is a companion study to another NCI trial (AEWS0031), which is examining the effectiveness of an intensified chemotherapy regimen for patients with Ewing sarcoma. The primary purposes of AEWS0031 are to determine: 1) if chemotherapy given every 2 weeks can cure more patients with Ewing sarcoma and similar tumors than chemotherapy given every 3 weeks; and 2) if certain biological characteristics of these tumors can predict how well the chemotherapy will work. Many, but not all, patients with Ewing sarcoma that has not metastasized can be cured with standard radiation, surgery, and chemotherapy treatment. Most patients whose tumors have spread, however, are not cured with standard treatment. A goal of future therapy is to identify patients at highest risk for metastasis so that they can be given more intensive therapy, and, conversely, patients at lower risk of relapse can receive less toxic treatment. Patients enrolled in AEWS0031 are eligible for this companion study. No additional procedures re required; RT-PCR testing will be performed on blood and bone marrow samples collected for AEWS0031. ...
