Clinical Trial Summary

Controlled, randomized phase III study, with the intent of optimizing the treatment of not metastatic Ewing Sarcoma. The patients will be randomized into 2 arms: standard treatment vs intensive treatment. Both arms will receive an induction treatment followed by surgery (wherever is possible) and/or radiotherapy. The maintenance treatment will be different on the basis of the response to the induction treatment (good or poor)

Description:

Eligible patients with non metastatic Ewing's Sarcoma will be randomized into 2 different arms: standard treatment arm A (based on the ISG/SSG III protocol) or into the experimental arm B(chemotherapy with dose intensification and shorter length of treatment).

Both arm will receive an induction treatment with higher dose intensity of doxorubicin and ifosfamide in Arm B.

After the induction treatment all the patient will undergo to local treatment (surgery and/or radiotherapy)that will be followed by a maintenance therapy.

The maintenance therapy will be different for both arms and, within each arm, on the basis of the response (histologically evaluated) of the pre-local treatment therapy.

Maintenance for Arm A: Poor responders will undergo to stem cells apheresis and their reinfusion after treatment with high doses of Busulfan and Melphalan 25 weeks.

Good responders will receive a 6 drugs maintenance treatment for 37 weeks (as per standard ISG/SSG III protocol)

Maintenance for Arm B: Poor responders will undergo to stem cells apheresis and their reinfusion after an intensified treatment with high doses of Busulfan and Melphalan (25 weeks).

Good responders will receive a maintenance treatment for 25 weeks

The primary aim of the study is to assess the Event Free Survival (EFS) that is expected to be similar in both arms

The secondary objectives are:

To assess if the induction treatment in Arm B is able to increase the percentage of good responders compared to those who receive standard treatment.

To assess the toxicity and the Quality of Life related to the chemotherapy treatment

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Event Free Survival (EFS)	The EFS (event defined as Progressive Disease , onset of local relapse and/or metastasis, death due to chemotherapy toxicity or for other causes) will be calculated from the first treatment day up to the event onset or to last follow-up	5 years
Secondary	Disease Free Survival (DFS)	The DFS will be calculated from the day that the patient will be free from disease (surgery date and/or radiotherapy completion) up to the date of progression disease or last follow-up	expected average 3 years
Secondary	Metastasis Free Survival	The Metastasis free Survival will be evaluated from the time of disease free (surgery performed and/or radiotherapy completed) to the onset of distance metastasis or last follow-up	expected average 2 years
Secondary	Overall Survival (OS)	The OS will be evaluated for the start treatment day to the day of death (for any causes)	expected average 5 years
