Abstract Text Sorafenib is an orally available multi-kinase inhibitor that inhibits tumor proliferation by targeting multiple kinases including the vascular endothelial growth factor receptors VEGFR1, VEGFR2, VEGFR3 and the platelet-derived growth factor receptor PDGFR, and it targets tumor progression by inhibiting FLT3, C-Kit and BRAF. Since BRAF mutations are frequent in melanoma, sorafenib was investigated in various Phase I, II and III clinical trials. The drug is well tolerated with mild to moderate adverse effects, which are mostly limited to cutaneous toxicity, diarrhea and fatigue.Systematic literature review of the randomized trials using PubMed was performed. Original articles were reviewed and citations from those were also considered. Additionally, clinical trial databases were examined to identify and summarize ongoing trials of sorafenib in melanoma patients.Sorafenib as a monotherapy or in combination with chemotherapy is of limited use. Combining it with dacarbazine doubled the response rate and the progression-free survival in metastatic melanoma patients. Unfortunately, these results have never been evaluated in large randomized Phase III clinical trials. According to the trials conducted so far a subpopulation of patients experience substantial benefit, therefore it is essential to identify biomarkers to select the subgroups of patients that are more likely to respond to sorafenib. Furthermore, other less frequent subtypes such as mucosal or ocular melanoma still constitute promising targets; academic institutions are currently launching investigator-initiated trials in these indications.

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
