描述 | Fibroblast growth factor receptor 2 (FGFR2) is receptor with tyrosine-kinase activity. FGFR2 amplification and high-level polysomy may be a promising molecular target for serous ovarian cancer. Alofanib is a predominantly FGFR2-selective allosteric small-molecular inhibitor that shows promising antiangiogenic and antitumor activities in preclinical studies. In the human ovarian cancer FGFR-expressing cell line, alofanib (ranging from 0 to 1 μM) significantly inhibited FGF-triggered cell proliferation in a dose-dependent manner. In FGFR2-overexpressing SKOV3 cell xenograft model, the combination of oral alofanib and paclitaxel/carboplatin produced a greater inhibitory effect on xenograft growth compared with vehicle group with inhibition rate over 63 %. Moreover, alofanib significantly decreased number of vessels in tumor (−49 %) and number of Ki-67-positive SKOV3 cells. Daily intravenous regimen of alofanib (total maximum dose per week was 350 mg/kg) dramaticly inhibited tumor growth by 80%[1]. |
