尽早结束审判

查找临床试验

大多数临床试验从始至终都按计划进行。 但有时审判会提早终止。 例如，如果参与者遇到意想不到的严重副作用，或者有明显证据表明危害大于收益，则IRB和DSMB可能会停止试验。

在某些情况下，由于以下原因，可能会停止试验：

• It is going very well. If there is clear evidence early-on that a new treatment or intervention is effective, then the trial may be halted so that the new treatment can be made widely available as soon as possible.

• Enough patients cannot be recruited

• The results of other trials are published that answer the research question or make it irrelevant
