Following a planned interim analysis, recruitment was put on hold while additional information was gathered and analysed. Recruitment did not resume. The final results of the trial included all 189 participants and longer follow-up.
Sertraline had little effect on depression, anxiety, fatigue or well-being. Irritability and sleeping were somewhat better with sertraline, but not a wide range of other common symptoms. Sertraline caused few side effects. Sertraline did not improve survival.
The ZEST Trial ruled out any major benefits of sertraline on symptoms, well-being, or survival in people with advanced cancer who did not have major depression.
