Brief Summary:
Regorafenib is an oral multikinase inhibitor that blocks the activity of kinases involved in angiogenesis (VEGFR 1,2,3 and TEK), oncogenesis (KIT, Ret Proto-Oncogene (RET), Raf-1 Proto-Oncogene, Serine/Threonine Kinase (RAF1) and BRAF) and tumour growth (PDGFR and FGFR). Epithelial ovarian cancer (EOC) cell lines frequently express high levels of vascular endothelial growth factor (VEGF) and in vivo preclinical studies evaluating Regorafenib have shown promising activity in ovarian cancer. In the clinic, anti-angiogenesis therapy with bevacizumab (a monoclonal antibody to VEGF) has already emerged as an important cornerstone in the management of ovarian cancer both as part of frontline adjuvant treatment and as second-line therapy for platinum-sensitive recurrent disease. Whilst Regorafenib has been FDA approved for the treatment of patients with metastatic colorectal cancer who have failed prior bevacizumab, it's role in the management of ovarian cancer remains to be defined.

  8. Adequate bone marrow function as shown by: absolute neutrophil count (ANC) ≥ 1.5 x 109/L, platelet count ≥ 100 x 109/L and haemoglobin (Hb) > 9 g/dl. Blood transfusion to meet the inclusion criteria will not be allowed.
  9. Adequate liver function as assess by: total bilirubin ≤ 1.5 x upper limit of normal (ULN), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 x ULN or ≤ 5.0 x ULN if liver metastases are present.
