2、的安全性和有效性。然而,1項已完成的Ⅲ期隨機雙盲安慰劑對照研究表明,Brivanib作為晚期肝癌二線治療手段(即sorafenib治療失敗者)并未顯著改善患者的總體生存期。另1項Ⅲ期隨機雙盲對照試驗結(jié)果也表明,Brivanib作為晚期肝癌一線治療手段并未比Sorafenib顯著改善患者的總體生存期。這2項臨床試驗的失敗使得其他兩項有關(guān)Brivanib治療肝癌的臨床試驗提前終止。通過分析以上研究認(rèn)為亞組分析以及事先篩選Brivanib可能獲益的肝癌患者(即FGF信號途徑激活的肝癌患者)也許對進(jìn)一步探究Brivanib的在肝癌治療中的角色是必要的。關(guān)鍵詞
