Summary
This study has multiple cohorts and treatment arms, based on diagnosis.
Group A (Very low risk HB): Participants are assigned to one of two groups:
- Group A1 (WDF): participants will undergo observation.
- Group A2 (Non-WDF): participants receive cisplatin (CDDP) chemotherapy intravenously (IV) on Day 1 following surgery. Treatment repeats every 21 days for up to 2 cycles.
Group B (Low risk HB): Participants receive cisplatin chemotherapy IV on Day 1. Treatment repeats every 14 days for up to 2 cycles. Participants are then assigned to one of 2 groups:
- Group B1 (Resectable): Participants receive 2 cycles of cisplatin, undergo surgery, then are randomised to 1 of 2 arms (2 vs 4 additional cycles of cisplatin):
- Group B1 Arm 4-CDDP: Participants receive cisplatin IV on Day 1. Treatment repeats every 14 days for up to 4 total cycles (2 pre-surgery, 2 post-surgery).
- Group B1 Arm 6-CDDP: Participants receive cisplatin IV on Day 1. Treatment repeats every 14 days for up to 6 total cycles (2 pre-surgery, 4 post-surgery).
- Group B2 (Unresectable): Participants receive 2 cycles of cisplatin, then are assigned to 1 of 2 arms (resectable vs unresectable):
- Group B2 Arm I (Resectable): Participants receive cisplatin IV on Day 1. Treatment repeats every 14 days for up to 6 total cycles (4 pre-surgery, 2 post-surgery). After cycle 4, participants undergo surgery, then continue with 2 additional cycles of cisplatin.
- Group B2 Arm II (Unresectable): Participants receive cisplatin IV on Day 1. Treatment repeats every 14 days for up to 6 total cycles.
Group C (Intermediate Risk HB): Participants are randomised to 1 of 2 arms.
- Group C Arm CDDP: Participants receive cisplatin IV on Day 1. Treatment repeats every 14 days fo rup to 6 cycles. Participants undergo surgery after cycle 2 or 4.
- Group C Arm C5VD: Participants receive cisplatin IV on Day 1, 5-fluorouracil IV, vincristine sulfate IV on Days 1, 8, and 15 and doxorubicin IV on Days 1 and 2. Treatment repeats every 21 days for up to 6 cycles. Participants undergo surgery after cycle 2 or 4.
Group D (High Risk HB): SIOPEL-4 IV Induction: Participants receive cisplatin IV on Day 1, 8, and 15 (for cycles 1 and 2) and Days 1 and 8 (for cycle 3) and doxorubicin IV on Days 8 and 9 (for cycles 1 and 2) and Days 1 and 2 (for cycle 3). Cycles 1 and 2 are 28-days, and cycle 3 is 21 days. Participants are then assigned to 1 of 2 arms:
- Group D1 (Consolidation Therapy): Participants with lung complete remission (either with chemotherapy and/or surgery) receive carboplatin IV on Day 1 and doxorubicin IV on Days 1 and 2. Treatment repeats every 21 days for 3 cycles.
- Group D2: Participants with residual metastatic disease are randomised to 1 of 2 arms:
- Group D2 Arm CE: Participants receive carboplatin IV on Days 1 and 2, doxorubicin IV over on Days 1 and 2 during cycles 1, 3 and 5, and carboplatin IV and etoposide IV on Day 1 and 2 of cycles 2, 4 and 6. Treatment repeats every 21 days for 6 cycles.
- Group D2 Arm VI: Participants receive carboplatin IV on Days 1 and 2 and doxorubicin IV on Days 1 and 2 during cycles 1, 3 and 5. Participants also receive vincristine sulfate IV over on Days 1 and 8 and irinotecan IV over once daily on Days 1 to 5 of cycles 2, 4 and 6. Treatment repeats every 21 days for 6 cycles.
Group E (Resected HCC): Participants are assigned to 1 of 2 groups.
- Group E1: Participants with HCC secondary to underlying hepatic disease undergo observation only.
- Group E2 (PLADO): Participants with de novo HCC receive cisplatin IV on Day 1, doxorubicin IV on Days 1 and 2 following surgery. Treatments repeat every 21 days for 4 cycles.
Group F (Unresected and/or metastatic HCC): Participants are randomised to 1 of 2 arms.
- Group F Arm 1 (PLADO): Participants receive cisplatin IV on Day 1, doxorubicin IV over on Days 1 and 2, and sorafenib orally twice daily on Days 3-21. Treatments repeat every 21 days for up to 3 cycles. Participants may undergo surgery, if tumours are resectable, or receive an additional 3 cycles of the treatment.
- Group F Arm 2 (P/GEMOX): Participants receive cisplatin IV on Day 1, doxorubicin IV over on Days 1 and 2, and sorafenib orally twice daily on Days 3-14 of cycles 1 and 3. Participants also receive gemcitabine IV on Day 1, oxaliplatin IV on Day 1 and Sorafenib orally on days 1-14 of cycles 2 and 4. Participants may undergo surgery, if tumours are resectable, or receive an additional 4 cycles of treatment.
Patients may undergo blood sample collection on study.
After completion of study treatment, patients are followed up for a minimum of 2 years.
