About this trial

The goal of this clinical trial is to learn if ACP-211 can help treat adults with major depressive disorder (MDD) who have not improved with antidepressant therapy (ADT), including those with treatment resistant depression (TRD).

The main questions the study aims to answer are:

* Does ACP-211 work better than a placebo (a look-alike capsule with no medicine) to reduce symptoms of depression? * What adverse events do participants have when taking ACP-211?
