Some of these people had previously been treated, unsuccessfully, with ipilimumab, confirming that the two drugs really do work in different ways.

The treatment of melanoma that started the ball rolling (and which was announced at the society's meeting three years ago) employed a drug called ipilimumab. This belongs to a class known as monoclonal antibodies.

这种黑色素瘤治疗是研究人员在三年前的协会会议上公布的。它使用一种名为易普利姆玛（Ipilimumab）的单克隆抗体药物。

In the original trials of ipilimumab, 11% of patients responded. That might not sound many, but those who did respond often did so strongly—surviving in some cases for years with no evidence of disease.

易普利姆玛在最初进行试验时，有11%的病人对药物产生反应。
