Combination Chemotherapy in Treating Young Patients With Nonmetastatic Rhabdomyosarcoma

2014-08-27 03:42:25 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known which combination chemotherapy regimen is more effective in treating rhabdomyosarcoma.

PURPOSE: This randomized phase III trial is studying different combination chemotherapy regimens to compare how well they work in treating young patients with nonmetastatic rhabdomyosarcoma.

Description

OBJECTIVES:

- Improve the outcome in pediatric patients with low-risk rhabdomyosarcoma (RMS) treated with vincristine and dactinomycin alone.

- Evaluate whether the outcome for older patients with standard-risk RMS with favorable features may be improved/maintained by administering a treatment with limited intensity.

- Evaluate whether chemotherapy intensity for patients with standard-risk RMS can be reduced, by lowering the cumulative dose of ifosfamide.

- Evaluate whether treatment can be reduced in a subgroup of patients with standard-risk RMS arising in an unfavorable site (e.g., parameningeal or other site) but with favorable site and age.

- Compare the value of standard chemotherapy comprising ifosfamide, vincristine, and dactinomycin with vs without doxorubicin (as early intensification in the initial part of treatment) in patients with high-risk RMS.

- Determine the role of low-dose maintenance chemotherapy comprising 6 months of cyclophosphamide and vinorelbine in patients with high-risk RMS.

- Improve the results in patients with poor prognosis (very high-risk) RMS treated with more intensive ifosfamide, vincristine, dactinomycin, and doxorubicin followed by maintenance chemotherapy.

OUTLINE: This is a non-blinded, randomized, prospective, multicenter study. Patients are stratified according to risk group (low risk vs standard risk vs high risk vs very high risk) and participating country.

- Stratum 1 (low-risk group): Patients receive vincristine IV on day 1 in weeks 1-4, 7-10, 13-16, and 19-22 and dactinomycin IV on day 1 in weeks 1, 4, 7, 10, 13, 16, 19, and 22.

- Stratum 2 (standard-risk group): Patients are assigned to 1 of 3 treatment groups according to their standard-risk subgroup.

- Subgroup B: Patients receive ifosfamide IV over 3 hours on days 1 and 2 in weeks 1, 4, 7, and 10; vincristine IV on day 1 in weeks 1-7, 10, 13, 16, 19, 22, and 25; and dactinomycin IV on day 1 in weeks 1, 4, 7, 10, 13, 16, 19, 22, and 25.

- Subgroup C: Patients receive ifosfamide IV over 3 hours on days 1 and 2 in weeks 1, 4, and 7; vincristine IV on day 1 in weeks 1-7; and dactinomycin IV on day 1 in weeks 1, 4, and 7. Patients are evaluated for tumor response in week 9. Patients in complete remission (CR) with favorable age and tumor size continue to receive ifosfamide, vincristine, and dactinomycin as above in weeks 10, 13, 16*, 19, 22, and 25. Patients may also undergo radiotherapy beginning in week 13 and continuing for 5-6 weeks. Patients in CR with unfavorable age or tumor size OR in partial remission (PR) (i.e., > 1/3 tumor volume reduction) continue to receive ifosfamide as above in weeks 10 and 16 and vincristine and dactinomycin as above in weeks 10, 13, 16*, 19, 22, and 25. These patients also undergo radiotherapy beginning in week 13 and continuing for 5-6 weeks. Patients with stable or progressive disease in week 9 proceed to second-line therapy and radiotherapy. Patients with residual disease after completion of chemotherapy in week 10 undergo surgical resection followed by ifosfamide, vincristine, and dactinomycin (with or without radiotherapy) as above in weeks 13, 16*, 19, 22, and 25.

- Subgroup D: Patients receive ifosfamide IV over 3 hours on days 1 and 2 in weeks 1, 4, and 7; vincristine IV on day 1 in weeks 1-7; and dactinomycin IV on day 1 in weeks 1, 4, and 7. Patients are evaluated for tumor response in week 9. Patients in CR or PR continue to receive ifosfamide, vincristine, and dactinomycin as above in weeks 10, 13, 16*, 19, 22, and 25. Patients may also undergo radiotherapy beginning in week 13 and continuing for 5-6 weeks. Patients with stable or progressive disease in week 9 proceed to second-line therapy and radiotherapy. Patients with residual disease after completion of chemotherapy in week 10 undergo surgical resection followed by ifosfamide, vincristine, and dactinomycin (with or without radiotherapy) as above in weeks 13, 16*, 19, 22, and 25.

NOTE: *Dactinomycin may be omitted during radiotherapy in week 16.

- Stratum 3 (high-risk group): Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients receive ifosfamide, vincristine, and dactinomycin as in subgroups C and D of stratum 2. Patients are evaluated for tumor response in week 9. Patients in CR or PR continue to receive ifosfamide, vincristine, and dactinomycin as in subgroups C and D of stratum 2. Patients may also undergo radiotherapy beginning in week 13 and continuing for 5-6 weeks. Patients with stable or progressive disease in week 9 proceed to second-line therapy and radiotherapy. Patients with residual disease after completion of chemotherapy in week 10 undergo surgical resection followed by ifosfamide, vincristine, and dactinomycin (with or without radiotherapy) as above in weeks 13, 16*, 19, 22, and 25.

- Arm II: Patients receive ifosfamide, vincristine, and dactinomycin as in subgroups C and D of stratum 2. Patients also receive doxorubicin IV over 4 hours on days 1 and 2 in weeks 1, 4, and 7. Patients are evaluated for tumor response in week 9. Patients in CR or PR continue to receive ifosfamide, vincristine, dactinomycin, and doxorubicin as above in week 10 and then ifosfamide, vincristine, and dactinomycin as above in weeks 13, 16*, 19, 22, and 25. Patients may also undergo radiotherapy beginning in week 13 and continuing for 5-6 weeks. Patients with stable or progressive disease in week 9 proceed to second-line therapy and radiotherapy. Patients with residual disease after completion of chemotherapy in week 10 undergo surgical resection followed by ifosfamide, vincristine, and dactinomycin (with or without radiotherapy) as above in weeks 13, 16*, 19, 22, and 25.

NOTE: *Dactinomycin may be omitted during radiotherapy in week 16.

- Maintenance chemotherapy: Patients who remain in CR or with minimal abnormalities on imaging studies after completion of therapy according to their randomized arm (as above) undergo a second randomization. Randomization occurs within 6 weeks after administration of the last course of chemotherapy on arm I or II.

- Arm I: Patients receive no maintenance chemotherapy.

- Arm II: Patients receive vinorelbine IV over 5-10 minutes on days 1, 8, and 15 and oral cyclophosphamide once daily on days 1-28. Treatment repeats every 28 days for up to 6 courses.

- Stratum 4 (very high-risk group): Patients receive ifosfamide, vincristine, and dactinomycin as in subgroups C and D of stratum 2. Patients also receive doxorubicin as in arm II of stratum 3. Patients are evaluated for tumor response in week 9. Patients in CR or PR continue to receive ifosfamide, vincristine, dactinomycin, and doxorubicin as in arm II of stratum 3. Patients may also undergo radiotherapy beginning in week 13 and continuing for 5-6 weeks. Patients with stable or progressive disease in week 9 proceed to second-line therapy and radiotherapy. Patients with residual disease after completion of chemotherapy in week 10 undergo surgical resection followed by ifosfamide, vincristine, and dactinomycin (with or without radiotherapy) as above in weeks 13, 16, 19, 22, and 25. After completion of chemotherapy, patients with a limited quantity of viable tumor proceed to maintenance chemotherapy.

- Maintenance chemotherapy: Patients receive vinorelbine IV over 5-10 minutes on days 1, 8, and 15 and oral cyclophosphamide once daily on days 1-28. Treatment repeats every 28 days for up to 6 courses.

- Second-line therapy: Patients in any stratum with stable or progressive disease in week 9 receive 1 of 2 second-line therapy regimens.

- Regimen 1: Patients receive topotecan IV on days 1-3 and carboplatin IV on days 4 and 5 in weeks 1 and 4. Patients are then evaluated for tumor response. Patients with good response receive topotecan IV on days 1-3 and cyclophosphamide IV on days 1 and 2 in weeks 7 and 13 and etoposide IV on days 1-3 and carboplatin IV on days 4 and 5 in weeks 10 and 16. Patients with no response receive local therapy or a new chemotherapy regimen.

- Regimen 2: Patients receive doxorubicin IV on day 1 and carboplatin IV on days 1 and 2 in weeks 1 and 4. Patients are then evaluated for tumor response. Patients with good response receive doxorubicin IV on day 1 in weeks 7, 10, 13, and 16; cyclophosphamide IV on days 1 and 2 in weeks 7 and 13; and carboplatin IV on days 1 and 2 of weeks 10 and 16. Patients with no response receive local therapy or a new chemotherapy regimen.

After completion of therapy, patients are followed periodically for at least 5 years.

Medical and Biotech [MESH] Definitions

A sulfhydryl compound used to prevent urothelial toxicity by inactivating metabolites from ANTINEOPLASTIC AGENTS, such as IFOSFAMIDE or CYCLOPHOSPHAMIDE.

Positional isomer of CYCLOPHOSPHAMIDE which is active as an alkylating agent and an immunosuppressive agent.

A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.

A major cytochrome P-450 enzyme which is inducible by PHENOBARBITAL in both the LIVER and SMALL INTESTINE. It is active in the metabolism of compounds like pentoxyresorufin, TESTOSTERONE, and ANDROSTENEDIONE. This enzyme, encoded by CYP2B1 gene, also mediates the activation of CYCLOPHOSPHAMIDE and IFOSFAMIDE to MUTAGENS.

A compound composed of a two CYCLIC PEPTIDES attached to a phenoxazine that is derived from STREPTOMYCES parvullus. It binds to DNA and inhibits RNA synthesis (transcription), with chain elongation more sensitive than initiation, termination, or release. As a result of impaired mRNA production, protein synthesis also declines after dactinomycin therapy. (From AMA Drug Evaluations Annual, 1993, p2015)
