Eligibility
Key inclusion criteria
1. Documentation of Disease

- Histologic Documentation: Confirmation of GCT histology (both seminoma and nonseminoma) on pathologic review at the center of enrollment.
- Tumor may have originated in any primary site. NOTE: In rare circumstances, patients will be allowed to enroll even if a pathological diagnosis may not have been established.
- This would require a clinical situation consistent with the diagnosis of GCT (testicular, peritoneal, retroperitoneal or mediastinal mass, elevated tumor marker levels {HCG greater than or equal to 500; AFP greater than or equal to 500} and typical pattern of metastases)

2. Evidence of Disease

- 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:

* 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.
* Consecutive elevated serum tumor markers (HCG or AFP) that are increasing. Increase of an elevated LDH alone does not constitute progressive disease.
* 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.

3. Prior Treatment

- Must have received 3-6 cycles of cisplatin-based chemotherapy as part of first-line (initial) chemotherapy.

* Prior POMBACE, CBOP-BEP, or GAMEC are allowed.
* 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.

- No more than one prior line of chemotherapy for GCT (other than the 1 cycle of salvage chemotherapy)

* 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.
* 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).
* 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.

- No prior treatment with high-dose chemotherapy (defined as treatment utilizing stem cell rescue)
- 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.
- No concurrent treatment with other cytotoxic drugs or targeted therapies.
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.
- 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.
- Must have adequate recovery from prior surgery (eg, healed scar, resumption of diet)

4. Age more than 14 years or above (more than 18 years or above in Germany)

5. ECOG Performance Status 0 to 2

6. Male gender

7. Required Initial Laboratory Values:

- Absolute Neutrophil Count (ANC) greater than or equal to 1,500/mm^3
- Platelet Count greater than or equal to 100,000/mm^3
- Calculated creatinine clearance greater than or equal to 50 mL/min
- Bilirubin less than or equal to 2.0 x upper limits of normal (ULN)
- AST/ALT less than or equal to 2.5 x upper limits of normal (ULN)

8. 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.

9. Negative Serology (antibody test) for the following infectious diseases:

- Human Immunodeficiency Virus (HIV) type 1 and 2
- Human T-cell Leukemia Virus (HTLV) type 1 and 2 (mandatory in US but optional in Canada and Europe)
- Hepatitis B surface antigen
- Hepatitis C antibody

10. No late relapse with completely surgically resectable disease. Patients with late relapses (defined as relapse 2 or more 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.

11. No large (2 cm or more) hemorrhagic or symptomatic brain metastases until local treatment has been administered (radiation therapy or surgery). Treatment may begin 7 days or more 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.

Radiation therapy should not be given concurrently with high-dose carboplatin or etoposide.

12. No secondary somatic malignancy arising from teratoma (e.g., teratoma with malignant transformation) when it is actively part of the disease recurrence or progression.

Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation). Stratified allocation is employed in the study. Patients are stratified by the following factors:
1. Geographic region (Europe, North America, Australia) that the patient lives in;
and by their
2. Modified IPFSG risk classification: i.e. allocated to one of the 3 groups: (i) low, (ii) intermediate and (iii) high.

Statistical methods / analysis
The study is an international collaboration with Europeans sites. It is anticipated that 168
patients from the Alliance sites and 252 patients from the European sites will be enrolled on the trial. These numbers are approximate and each region will continue to enroll patients even if the target number per site has not been reached.

It is expected that a proportion of patients will be cured. The Berkson-Gage exponential cure rate model is used to design this trial. This model assumes that a proportion of patients (p) will be cured and (1-p) who will fail according to an exponential distribution with rate 'lambda'.

The overall survival function S(t) for the TIP (arm A) and TI-CE (arm B) are expressed as:
S1(t) = p+ (1-p)exp(-'lambda't)
S2 (t) = (p+ (1-p)exp(-'lambda't))'theta'

Respectively, where 'theta' is the hazard ratio under the proportional hazards alternative. It is assumed that 35% of patients will be cured and the median survival time for patients
randomized to TIP who are not cured to be 1.5 years. Moreover, it is hypothesized that TICE
will reduce the hazard by 29% under that proportional hazards alternative ('theta' =0.71). The
expected information in both arms is 232 deaths. The calculation assumes a yearly
enrollment rate of 72 patients accrued over 5.8 years and a post-accrual period of 4.5 years
after study closure. This design has 81% power assuming a one sided type I error rate of
0.05.
