Study of Oxaliplatin and Sorafenib Combination to Treat Gastric Cancer Relapsed After a Cisplatin Based Treatment
Study Details
Study Description
Brief Summary
In Spain, the gastric carcinoma is the 5th most frequent malignant tumor in women and the 6th in men, and represents the 3rd cause of cancer-related deaths amongst women and the 4th amongst men. The average of 5-year survival rate in Spain is under 30%. The main reason of it is that, despite carrying out an adjuvant treatment, more than the 50% will present relapsed disease.
Sorafenib has been the first RAF inhibitor, both of RAF-1 and B-rRAF and its b-RAF variant V600E. Moreover, it has shown its ability to inhibit other tyrosin-quinase receptors as VEGFR 2 and 3, c-kit, Flt-3 or PDGFR. Its activity has been clearly proven in clear cell renal carcinoma.
The mechanism by which Sorafenib seems to act is not because of the existence of a mutation of RAS or RAF, but because as there is a VHL shortage the HIP produces a VEGF, bFGF or TGF overexpression that produces in turn a hyper-stimulation on the RAF/ERK/MEK pathway.
The RAF/MEK/ERK pathway and angiogenesis seem to be clearly involved in the gastric carcinoma tumorigenesis and progression. Because of that, it seems interesting to associate Sorafenib to an oxaliplatin-based chemotherapy, which has shown its effectiveness in relapsed patients after receiving cisplatin-based schemes. Moreover, there is a phase 1 trial confirming the tolerance of the oxaliplatin and Sorafenib association, describing partial responses amongst gastric cancer patients previously treated with cisplatin.
