Brief summary

Dose-limiting toxicity (DLT) -DLT will be defined as any of the following haematological and non-haematological events (CTCAE v5.0) that occur during the DLT assessment period (4 weeks after the start of treatment = cycle 1) and are at least possibly related (possibly, probably, or definitely) attributable to VDC/IE + regorafenib, Any grade ≥ 3 (hematological or non-hematological) toxicity leading to delay of start of day 15 by > 7 days (i.e: starting > day 21) or day 1 of cycle 2 by > 14 days ((i.e: starting > day 42), Any dose interruption or reduction due to toxicity which results in administration of less than 80% of the planned dosage of regorafenib or 75% of the planned dosage of chemotherapy in the first cyle of 28 days of treatment., Any grade ≥ 3 toxicity resulting in permanent discontinuation of the regorafenib, Any grade 5 toxicity related to study treatment (death)

Detailed description

Overall Survival (OS) and progression-free survival (PFS), Adverse events and toxicity, defined by CTCAE v5.0, Histological response of the primary tumor to induction chemotherapy if surgery is performed as local control, Radiological response of primary tumor, regional lymph nodes and/or metastases
