Study 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.

Read the detailed description

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 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 pathologic 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 ≥ 500; AFP ≥ 500} and typical pattern of )
  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 of new or growing or unresectable lesions demonstrating viable non-teratomatous GCT (enrollment on this study for 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 (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 as defined in the protocol)

      • 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 , 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 ≥ 14 years (≥ 18 years in Germany)
  5. Performance Status 0 to 2
  6. Male gender
  7. Required Initial Laboratory Values:

    • (ANC) ≥ 1,500/mm\^3
    • Count ≥ 100,000/mm\^3
    • Calculated ≥ 50 mL/min
    • ≤ 2.0 x (ULN)
    • /ALT ≤ 2.5 x upper limits of normal (ULN)
  8. No concurrent 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:

    • (HIV) type 1 and 2
    • Human T-cell Leukemia Virus (HTLV) type 1 and 2 (mandatory in US but optional in Canada and Europe)
    • surface antigen
    • antibody
  10. 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.
  11. 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.

    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.
Terms in these criteria, in plain language(16)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
