Efficacy of Dose Intensification in Patients With Non-metastatic Ewing

Status Completed

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)

Clinical Trial 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 ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

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.
