  慢性髓性白血病

  2012年9月4日,美国食品与药物管理局(FDA)批准了新的“孤儿药”伯舒替尼(bosutinib)用于治疗慢性髓性白血病(CML),后者以老年人发病居多。

  伯舒替尼预期用于那些慢性期、加速期或急变期Ph染色体阳性的CML患者,这些患者对其他治疗包括伊马替尼(imatinib)治疗不耐受或有抵抗。

  大多数CML患者有基因突变,可见费城(Ph)染色体,该染色体可导致骨髓产生酪氨酸激酶,后者启动大量异常粒细胞增殖。伯舒替尼通过阻断酪氨酸激酶信号而发挥作用。

  一项纳入546例成人患者的临床试验证实了伯舒替尼的安全性和有效性。

  接受伯舒替尼治疗的患者最常见不良反应包括腹痛、腹泻,恶心、呕吐,血小板减少,皮疹,贫血,发热和疲劳。

  FDA批准的治疗CML其他药物包括伊马替尼(2001),达沙替尼(dasatinib ,2006)和尼洛替尼(nilotinib ,2007)。
