Second, regulators have speeded up their approval of cancer drugs.

Little surprise, then, that big drugmakers are keen to develop their own cancer drugs, form partnerships with smaller firms that have promising treatments in the pipeline, and buy such companies outright.
有个小惊喜就是大制药公司都热衷于开发自己的抗癌药物，与在治疗过程中能提高治疗效果的小公司形成合作关系，也直接收购这种小公司。
Kyprolis was first developed by a small firm called Proteolix, which was bought by Onyx, now acquired by Amgen.
首先Kyprolis是由一个叫 Proteolix的小公司开发的，被Onyx收购，现在又被Amgen收购。

AstraZeneca is buying Amplimmune largely for two cancer drugs still in early testing.
阿斯利康购买Amplimmune主要是两种抗癌药物目前仍处于早期测试。
