Official title

A Phase 3 Multi-institutional Study for Treatment of Children With Newly Diagnosed Hepatoblastoma Using a Modified PHITT Strategy Incorporating a Randomized Assessment of Sodium Thiosulfate as Otoprotection for Children With Localized Disease, and Response Adapted Therapy for Patients With Metastatic Disease

Overview

A Phase 3 multi-institutional study for treatment of children with newly diagnosed hepatoblastoma using a modified Paediatric Hepatic International Tumour Trial (PHITT) strategy incorporating a randomized assessment of sodium thiosulfate as auditory protection for children with localized disease, and response adapted therapy for patients with metastatic disease

Detailed description

Primary aims:

1. Localized Disease: Groups B and C: To evaluate and validate the efficacy of sodium thiosulfate (STS) to reduce the hearing impairment caused by a cisplatin monotherapy in non-metastatic patients without adverse features (localized PRETEXT I-III tumors without positive VPEFR annotation factors) (Group B - treated with cisplatin mono-therapy) or with adverse features (localized PRETEXT I-III tumors with positive VPEFR annotation factors) (Group C - treated with regimen C5VD) 2. Metastatic Disease: Group D: To determine the 3-year Event-free survival (EFS) in patients with metastatic disease treated with International Society of Paediatric Oncology (SIOPEL 4) induction therapy followed by response adapted consolidation therapy. 3. To determine the 3-year EFS in patients with HB whose tumor is completely resected at diagnosis (Group A) and either receive no adjuvant chemotherapy (Group A1, completely resected well differentiated fetal (WDF) histology HB) or 2 cycles of standard dose cisplatin monotherapy (Group A2, completely resected non-well differentiated fetal histology HB)

Secondary aims:

1. To determine any impact of STS on chemotherapy response and survival in children with localized hepatoblastoma 2. To assess the feasibility of complete resection after 2 cycles of interval compressed lower dose cisplatin monotherapy (80 mg/m2/cycle) in non-metastatic patients and without adverse features 3. To assess the feasibility of complete resection after 2 cycles of C5VD in non-metastatic patients with adverse features.5. To determine the adherence to PRETEXT and Post-treatment extent of disease (POSTTEXT) based surgical guidelines 4. To determine the prognostic relevance in HB of a "small cell undifferentiated", tumor component, percentage of tumor necrosis in post chemotherapy specimens, and the relevance of a positive microscopic margin in resected HB specimens. 5. To determine the concordance between institutional, regional expert panel (prospective) and international expert panel (retrospective) review assessment of PRETEXT and POSTTEXT stage, and correlate with outcome variables. 6. To prospectively collect patient HB tumor, peripheral blood and urine specimens, for translational biology studies.

Interventions

• Drug Sodium Thiosulfate Injection
  Weight ≥ 10 kg: 20 g/m2/dose STS or Weight 5-10 kg: 15 g/m2/dose STS or Weight \< 5 kg: 10 g/m2/dose STS will be administered by IV over 2 hours beginning 6 hours after the completion of each cisplatin infusion.
• Procedure Primary surgery resection
  Resection of the primary tumor up-front
• Drug mono CDDP-Group A2
  Cisplatin 100 mg/m2/dose Day 1 . All non-WDF patients (A2) will receive 2 cycles of mono cisplatin (100 mg/m2/dose) chemotherapy. Each cycle lasts 3 weeks (21 days).
• Drug Cisplatin, 5-Fluorouracil, Vincristine, Doxorubicin-Group C
  All the patients in Group C (2 arms) will receive 6 cycles chemotherapy in total. Cisplatin 100 mg/m2/dose Day 1; 5-Fluorouracil 600 mg/m2/dose Day 1; Vincristine 1.5 mg/m2/dose Day 1,8 and 15; Doxorubicin 30 mg/m2/dose Day 1 and 2; (Dexrazoxane : 300 mg/m2/dose Day 1 and 2, where is available)
• Procedure Biopsy
  Tumors are deemed unresectable at diagnosis.
• Procedure Resection or transplant
  Ideal timing to resect of the primary tumors or transplant if if excellent response achieved at 1st or 2nd evaluation timepoint. But surgery timing is not mandated. Irrespective of the timing of surgery, patients should complete all planned protocol cycles of chemotherapy (including post transplantation). If surgical resection of the primary tumor is delayed until the end of therapy, no further post-operative chemotherapy should be given.
• Procedure Resection of pulmonary nodules
  Resection of pulmonary nodules should be considered in Group D2, patients at any cycle if continuing to respond to consolidation therapy.
• Drug mono CDDP- Group B
  Cisplatin 80 mg/m2/dose Day 1. All patients in Group B (2 arms) will receive 6 cycles of mono cisplatin chemotherapy. Each cycle lasts 2 weeks (14 days).
• Drug Block 1 to 3 (Cisplatin, Doxorubicin) Group D
  Block 1 and 2: Cisplatin 70 mg/m2/dose Day1, 8 and 15; Doxorubicin 30 mg/m2/dose, Day 8 and 9; (Dexrazoxane: 300 mg/m2/dose Day 1 and 2, where is available); Block 3: Cisplatin 70 mg/m2/dose Day1and 8; Doxorubicin 30 mg/m2/dose Day 8 and 9; (Dexrazoxane BSA ≥ 0.6 m2/dose: 300 mg/m2/dose Day 8 and 9, where is available) All patients in Group D will receive 3 blocks in induction, followed by consolidation therapy. Block 1 and 2 last 28 days. Block 3 is 21 cycles.
• Drug Consolidation (Carboplatin, Doxorubicin) -Group D1
  Following Block 1-3 of induction therapy, Group D1 patients will receive 3 cycles of Carboplatin + Doxorubicin consolidation therapy. Each cycle lasts 3 weeks (21 days). Carboplatin 500 mg/m2/dose Day 1; Doxorubicin 20 mg/m2/dose Day 1 and 2; (Dexrazoxane: 200 mg/m2/dose Day 1 and 2, where is available).

Primary outcome measures

• Audiogram [Time frame: From diagnosis through study completion, an average of 1 year]

Eligibility criteria

Inclusion criteria

• Performance Level Patients must have a performance status corresponding to ECOG scores 0, 1, or 2. Use Karnofsky for patients >16 years of age and Lansky for patients ≤16 years of age.
• Diagnosis Patients must be newly diagnosed with histologically-proven primary pediatric HB
• Emergent Treatment for HB In emergency situation when a patient meets all other eligibility criteria and has had baseline required observations, but is too ill to undergo a biopsy safely, the patient may be enrolled without a biopsy.
• Prior Therapy Patients may have had surgical resection of the hepatic malignancy prior to enrollment. All other anti-cancer therapy for the current liver lesion is prohibited.
• Organ Function Requirements

I) Adequate renal function defined as:

Creatinine clearance or radioisotope Glomerular Filtration Rate (GFR) ≥ 70 mL/min/1.73 m2

II) Adequate liver function defined as:

Total bilirubin ≤ 5 x upper limit of normal (ULN) for age, and Aspartate aminotransferase (AST) or Alanine transaminase (ALT) < 10 x upper limit of normal (ULN) for age.

III) Adequate pulmonary function defined as:

Normal pulmonary function tests (including DLCO) if there is clinical indication for determination (e.g. dyspnea at rest, known requirement for supplemental oxygen)

Exclusion criteria

• Prior chemotherapy or tumor directed therapy expect for surgical resection of the hepatic malignancy (i.e. radiation therapy, biologic agents, local therapy (embolization, radiofrequency ablation, and laser)). Therefore, patients with a pre-disposition syndrome who have a prior malignancy are not eligible.
• Patients who are currently receiving another investigational drug.
• Patients who are currently receiving other anticancer agents.
• Patients with uncontrolled infection.
• Patients who previously received a solid organ transplant.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
