儘早結束審判

查找臨床試驗

大多數臨床試驗從始至終都按計劃進行。 但有時審判會提早終止。 例如，如果參與者遇到意想不到的嚴重副作用，或者有明顯證據表明危害大於收益，則IRB和DSMB可能會停止試驗。

在某些情況下，由於以下原因，可能會停止試驗：

• 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
