Vinblastine, Celecoxib, and Combination Chemotherapy in Treating Patients With Newly-Diagnosed Metastatic Ewing's Sarcoma Family of Tumors

Registration Number
NCT00061893
Lead Sponsor
Children's Oncology Group
Brief Summary

RATIONALE: Drugs used in chemotherapy, such as vinblastine, work in different ways to stop tumor cells from dividing so they stop growing or die. Celecoxib may stop the growth of Ewing's sarcoma by stopping blood flow to the tumor. Combining more than one chemotherapy drug with celecoxib may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining low-dose vinblastine and celecoxib with standard regimens of combination chemotherapy in treating patients who have newly-diagnosed metastatic Ewing's sarcoma family of tumors.

Detailed Description

OBJECTIVES:

* Determine the feasibility and safety of low-dose vinblastine and celecoxib in combination with standard multiagent chemotherapy in patients with newly diagnosed metastatic Ewing's sarcoma family of tumors.

* Determine the event-free survival of patients treated with this regimen.

* Determine the pharmacokinetics of this regimen in these patients.

OUTLINE: This is a pilot, multicenter study.

* Induction therapy: Patients receive the following alternating regimens:

* VAC (courses 1 and 3): Patients receive vincristine IV and cyclophosphamide IV over 1 hour on day 1 and doxorubicin IV continuously on days 1 and 2 of weeks 1 and 7.

* IE (courses 2 and 4): Patients receive ifosfamide IV over 1 hour and etoposide IV over 1-2 hours on days 1-5 of weeks 4 and 10.

Patients also receive filgrastim (G-CSF) subcutaneously (SC) beginning 24-48 hours after the last dose of chemotherapy and continuing until blood counts recover.

Treatment repeats every 21 days for a total of 4 courses in the absence of disease progression or unacceptable toxicity.

* Local control and consolidation therapy: Beginning on week 13, patients are assigned to 1 of 4 regimens based on disease status.

* Regimen A (surgery only): Patients who respond to induction chemotherapy undergo surgery on week 13. Patients then begin consolidation therapy on week 15 with the following alternating regimens:

* VAC (courses 5, 7, and 9): Patients receive VAC on weeks 15, 21, and 27.

* IE (courses 6, 8, 10, 12, and 14): Patients receive IE on weeks 18, 24, 30, 36, and 42.

* VC (courses 11 and 13): Patients receive vincristine IV and cyclophosphamide IV over 1 hour on weeks 33 and 39.

* Regimen B (radiotherapy only): Patients with unresectable lesions undergo radiotherapy once daily 5 days a week for up to approximately 6 weeks beginning on week 13. Patients also receive consolidation therapy beginning on week 13, with the following alternating regimens:

* VAC (courses 5, 9, and 11): Patients receive VAC on weeks 13, 25, and 31.

* IE (courses 6, 8, 10, 12, and 14): Patients receive IE on weeks 16, 22, 28, 34, and 40.

* VC (courses 7 and 13): Patients receive VC on weeks 19 and 37.

* Regimen C (surgery and radiotherapy): Patients who respond to induction chemotherapy undergo surgery on week 13. Patients who have inadequate margins after surgery undergo radiotherapy (as in regimen B) beginning on week 15. Patients also receive consolidation therapy, beginning on week 15, with the following alternating regimens:

* VAC (courses 5, 9, and 11): Patients receive VAC on weeks 15, 27, and 33.

* IE (courses 6, 8, 10, 12, and 14): Patients receive IE on weeks 18, 24, 30, 36, and 42.

* VC (courses 7 and 13): Patients receive VC on weeks 21 and 39.

* Regimen D (preoperative radiotherapy): Patients with bulky lesions who do not have a good clinical and radiographic response to induction therapy begin consolidation therapy on week 13 with VAC (course 5) and undergo concurrent radiotherapy as in regimen B. Patients then receive IE on weeks 16 and 19 for courses 6 and 7. Patients undergo surgery on week 22. Patients continue consolidation therapy with the following alternating regimens:

* VAC (courses 8 and 9): Patients receive VAC on weeks 24 and 27.

* IE (courses 10, 12, and 14): Patients receive IE on weeks 30, 36, and 42.

* VC (courses 11 and 13): Patients receive VC on weeks 33 and 39. Patients receive G-CSF SC (as in induction therapy) during all consolidation courses.

Consolidation therapy continues for 10 courses in the absence of disease progression or unacceptable toxicity.

* Vinblastine and celecoxib therapy: Throughout induction, local control, and consolidation therapies, patients also receive vinblastine IV 3 times a week (twice a week during the weeks that vincristine is given) and oral celecoxib twice daily, beginning on day 1 of course 1 and continuing until the completion of course 14.\* NOTE: \*To assess for safety, the first 6 patients enrolled receive vinblastine only during courses 1 and 2 and celecoxib is then added for all subsequent courses.

Patients are followed every 3 months for 3 years and then every 6 months for 2 years.

PROJECTED ACCRUAL: A total of 6-36 patients will be accrued for this study within 1.17 years.

Primary Outcome Measures
NameTimeMethod
Occurrence of Severe ToxicityThe first two cycles (6 weeks) of protocol chemotherapy

An incidence of severe toxicity is defined to be the occurrence of grade 3 or higher infection or grade 3 or higher sensory neuropathy during cycles 1-2 of protocol therapy. If 12 or more patients experience grade 3 or higher infection or five or more patients experience grade 3 or higher sensory neuropathy during cycles 1-2 of protocol therapy, the regimen will be flagged as being associated with an excessive rate of severe toxicity.
