Chemotherapy + Targeted Therapy for Ewing Sarcoma
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores new treatments for Ewing sarcoma and desmoplastic small round cell tumor, focusing on the effectiveness of chemotherapy and targeted therapy. For Ewing sarcoma, it compares standard treatment with a new combination for higher-risk individuals, such as those with cancer that has spread or is located in the pelvis. Individuals with Ewing sarcoma or desmoplastic small round cell tumor who have not received previous cancer treatments and meet specific health criteria may find this trial suitable. Researchers will monitor participants for 10 years to assess the treatments' effectiveness and safety. As a Phase 2 trial, the research measures how well the treatment works in an initial, smaller group of people.
Will I have to stop taking my current medications?
The trial protocol does not specify if you must stop taking your current medications, but if you are in Group B and will receive upfront window therapy, you must not take certain medications like azole antifungals, rifampin, phenytoin, phenobarbitol, carbamazepine, grapefruit juice, and St. John's wort within 1 week before starting the study.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that the chemotherapy drugs used in Group A for standard-risk Ewing sarcoma are generally well-tolerated. These drugs include vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide, which form the usual treatment for this condition. While these drugs can cause side effects, they are commonly used, and doctors have extensive experience managing these effects.
Group B, which involves a high-risk treatment plan, includes additional drugs alongside those in Group A. These drugs are irinotecan, temozolomide, temsirolimus, bevacizumab, and sorafenib. Although this combination is more complex, research has previously used these drugs in various ways. Each drug has known side effects, but doctors are skilled in handling them.
As this trial is in an early phase, researchers continue to study how well participants tolerate these treatments. Participants receive close monitoring for any side effects.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for Ewing Sarcoma because they combine traditional chemotherapy with targeted therapies, aiming for a more personalized approach. Unlike standard treatments that typically rely solely on chemotherapy, this approach includes drugs like temsirolimus and sorafenib, which specifically target cancer cell growth pathways. Additionally, the inclusion of bevacizumab, an anti-angiogenic agent, aims to cut off the blood supply to tumors, potentially enhancing treatment effectiveness. This combination of traditional and targeted therapies holds promise for improved outcomes, especially in high-risk patients.
What evidence suggests that this trial's treatments could be effective for Ewing sarcoma?
Research has shown that treatments using vincristine, doxorubicin, and cyclophosphamide have been successful for standard-risk Ewing sarcoma. In this trial, participants in the standard-risk group will receive these drugs, often combined with ifosfamide and etoposide, which are effective when the cancer hasn't spread.
For high-risk cases, where the cancer has spread or is more difficult to treat, this trial tests a combination of chemotherapy and targeted therapies. Participants in the high-risk group will receive drugs like irinotecan and temozolomide, which aim to attack cancer cells more precisely. Previous studies suggest these combinations might improve outcomes for high-risk patients, especially when traditional treatments are insufficient.23467Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for children under 14 with non-pelvic ESFT and young adults up to 25 years old with high-risk ESFT or DSRCT, including those with metastatic disease, pelvic tumors, or intra-abdominal DSRCT. Participants must have proper organ function and no prior cancer treatments (except emergency radiation). They should not be pregnant/breastfeeding and must agree to use birth control.Inclusion Criteria

Trial Overview
The study tests standard treatment in Group A (standard risk) children under 14 without pelvic tumors or spread of the disease. Group B (high risk), older than 14, with pelvic tumors or metastasis receive more aggressive therapy. Treatments include chemotherapy drugs like vincristine and doxorubicin, targeted therapies such as temsirolimus and sorafenib, surgery, radiation, plus long-term follow-up.

Treatment groups
Active Control
Participants will receive vincristine, doxorubicin, cyclophosphamide, ifosfamide and etoposide. Doxorubicin will be omitted following a total cumulative dose of 375 mg/m\^2. Depending on the size and location of the participant's tumor, they will have surgery alone, radiation alone, or surgery followed by radiation. Local control measures (surgery and/or radiation therapy) will be instituted after 6 courses of chemotherapy. Total duration of treatment is approximately 29 weeks.
Participants will receive vincristine, doxorubicin, cyclophosphamide, ifosfamide, etoposide, irinotecan, temozolomide, temsirolimus, bevacizumab, and sorafenib.
