Description

Summary

This randomized phase III trial studies how well standard-dose combination chemotherapy works compared to high-dose combination chemotherapy and stem cell transplant in treating patients with germ cell tumors that have returned after a period of improvement or did not respond to treatment. Drugs used in chemotherapy, such as paclitaxel, ifosfamide, cisplatin, carboplatin, and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before a stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as filgrastim or pegfilgrastim, and certain chemotherapy drugs, helps stem cells move from the bone marrow to the blood so they can be collected and stored. Chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. It is not yet known whether high-dose combination chemotherapy and stem cell transplant are more effective than standard-dose combination chemotherapy in treating patients with refractory or relapsed germ cell tumors.

Official Title

A Randomized Phase III Trial Comparing Conventional-Dose Chemotherapy Using Paclitaxel, Ifosfamide, and Cisplatin (TIP) With High-Dose Chemotherapy Using Mobilizing Paclitaxel Plus Ifosfamide Followed by High-Dose Carboplatin and Etoposide (TI-CE) as First Salvage Treatment in Relapsed or Refractory Germ Cell Tumors

Details

The study is an international collaboration with European sites. Collaborators on the study include the National Cancer Institute, the European Organization for Research and Treatment of Cancer and the Movember Foundation. Randomization will be stratified by region (North America and Europe) and by modified IPFSG (International Prognostic Factor Study Group) risk classification (low, intermediate and high). The primary and secondary objectives are described below.

Primary Objective:

  1. To compare the overall survival in patients treated with conventional-dose chemotherapy using the TIP regimen with high-dose chemotherapy (HDCT) plus autologous stem cell transplant (ASCT) using the TI-CE regimen as initial salvage treatment of patients with relapsed or refractory germ cell tumors (GCT)

Secondary Objectives:

  1. To compare the progression-free survival (PFS) of patients treated with initial salvage HDCT with TI-CE versus initial salvage CDCT with TIP
  2. To compare the favorable response rate (FRR) of patients treated with initial salvage HDCT with TI-CE versus initial salvage CDCT with TIP
  3. To compare the toxicity, including treatment-related mortality, associated with high-dose chemotherapy and ASCT using TI-CE compared with conventional-dose chemotherapy using TIP as initial salvage treatment for patients with relapsed or refractory GCT
  4. To prospectively evaluate the IPFSG scoring system as a predictor of outcome to initial salvage therapy in patients with relapsed or refractory GCT. In this trial, randomization will be stratified by a modification of their IPFSG category and we will prospectively evaluate whether or not actual outcomes vary by risk group in the appropriate manner (low risk patients have higher OS than high-risk group).
  5. To evaluate the association between tumor marker decline rates of Alpha-Fetoprotein (AFP) and Human Chorionic Gonadotropin (HCG) with OS and PFS.

Treatment is to continue until disease progression, unacceptable toxicity or completion of all protocol treatment.

Eligibility

For males ages 14 years and up

  1. Documentation of Disease
  2. Histologic Documentation: Confirmation of GCT histology (both seminoma and nonseminoma) on pathologic review at the center of enrollment.
  3. Tumor may have originated in any primary site. NOTE: In rare circumstances,patients will be allowed to enroll even if a pathologic diagnosis may not have been established.
  4. This would require a clinical situation consistent with the diagnosis of GCT(testicular, peritoneal, retroperitoneal or mediastinal mass, elevated tumor marker levels {HCG ≥ 500; AFP ≥ 500} and typical pattern of metastases)
  5. Evidence of Disease
  6. Must have evidence of progressive or recurrent GCT (measurable or non-measurable)following one line of cisplatin-based chemotherapy, defined as meeting at least one of the following criteria:
  7. Tumor biopsy of new or growing or unresectable lesions demonstrating viable non-teratomatous GCT (enrollment on this study for adjuvant treatment after macroscopically complete resection of viable GCT is not allowed). In the event of an incomplete gross resection where viable GCT is found, patients will be considered eligible for the study.
  8. Consecutive elevated serum tumor markers (HCG or AFP) that are increasing.Increase of an elevated LDH alone does not constitute progressive disease.
  9. Development of new or enlarging lesions in the setting of persistently elevated HCG or AFP, even if the HCG and AFP are not continuing to increase.
  10. Prior Treatment
  11. Must have received 3-6 cycles of cisplatin-based chemotherapy as part of first-line (initial) chemotherapy.
  12. Prior POMBACE, CBOP-BEP, or GAMEC are allowed.
  13. Note: For patients requiring immediate treatment, 1 cycle of conventional-dose salvage chemotherapy is allowed. Therefore, these patients may have received 7 prior cycles of chemotherapy. 6 cycles as part of first-line chemotherapy and 1 cycle of salvage conventional chemotherapy.
  14. No more than one prior line of chemotherapy for GCT (other than the 1 cycle of salvage chemotherapy as defined in the protocol)
  15. Definition of one line of chemotherapy: One line of therapy can in some cases consist of 2 different cisplatin-based treatment combinations,provided there is no disease progression between these two regimens.
  16. Prior treatment with carboplatin as adjuvant therapy is allowed, provided patients meet other eligibility criteria (e.g., the patient has also received 3-4 cycles of cisplatin-based chemotherapy).
  17. Prior treatment with 1-2 cycles of BEP or EP as adjuvant chemotherapy for early stage GCT is allowed, provided the patient also received 3-4 cycles of BEP or EP again at relapse. Patients treated with 3-4 cycles of VIP at relapse following 1-2 cycles of BEP/EP are not eligible as this would be considered more than 1 line of prior therapy.
  18. No prior treatment with high-dose chemotherapy (defined as treatment utilizing stem cell rescue)
  19. No prior treatment with TIP with the exception when given as a bridge to treatment on protocol for patients with rapidly progressive disease who cannot wait to complete the eligibility screening process. Only one cycle is allowed.
  20. No concurrent treatment with other cytotoxic drugs or targeted therapies.
  21. No radiation therapy (other than to the brain) within 14 days of day 1 of protocol chemotherapy except radiation to brain metastases, which must be completed 7 days prior to start of chemotherapy.
  22. No previous chemotherapy within 17 days prior to enrollment. A minimum of three weeks after the last day of the start of the previous chemotherapy regimen before the first day of chemotherapy on study protocol.
  23. Must have adequate recovery from prior surgery (eg, healed scar, resumption of diet)
  24. Age ≥ 14 years (≥ 18 years in Germany)
  25. ECOG Performance Status 0 to 2
  26. Male gender
  27. Required Initial Laboratory Values:
  28. Absolute Neutrophil Count (ANC) ≥ 1,500/mm3

  29. Platelet Count ≥ 100,000/mm3

  32. AST/ALT ≤ 2.5 x upper limits of normal (ULN)
  33. No concurrent malignancy other than non-melanoma skin cancer, superficial noninvasive(pTa or pTis) TCC of the bladder, contralateral GCT, or intratubular germ cell neoplasia. Patients with a prior malignancy, but at least 2 years since any evidence of disease are allowed.
  34. Negative Serology (antibody test) for the following infectious diseases:
  35. Human Immunodeficiency Virus (HIV) type 1 and 2
  36. Human T-cell Leukemia Virus (HTLV) type 1 and 2 (mandatory in US but optional in Canada and Europe)
  37. Hepatitis B surface antigen
  38. Hepatitis C antibody
  39. . No late relapse with completely surgically resectable disease. Patients with late relapses (defined as relapse ≥ 2 years from the date of completion of the last chemotherapy regimen) whose disease is completely surgically resectable are not eligible. Patients with late relapses who have unresectable disease are eligible.
  40. . No large (≥ 2 cm) hemorrhagic or symptomatic brain metastases until local treatment has been administered (radiation therapy or surgery). Treatment may begin ≥ 7 days after completion of local treatment. Patients with small (< 2 cm) and asymptomatic brain metastases are allowed and may be treated with radiation therapy and/or surgery concurrently with Arm A or cycles 1 and 2 of Arm B if deemed medically indicated.
