Living with depression that hasn't improved with antidepressants?

Learn more about a research study of an investigational drug for adults who have been diagnosed with major depressive disorder(MDD) and have used an antidepressant medication without sufficient improvement in their depression symptoms.

If you're eighteen to sixty-five and haven't found relief with one to three antidepressants, you may be eligible to participate.

What is the purpose of this study?

In this study, doctors want to evaluate the safety and effectiveness of an oral investigational drug when it is combined with an approved antidepressant treatment.Researchers want to compare the investigational drug to placebo, which looks like the investigational drug but contains no active medication. In this study, the term “study drug”refers to either the investigational medication or placebo.


The investigational drug is not approved to treat MDD. Only peoplewho participate in a research study like this one can receive it. Youmay not directly benefit from participating in this study. However, the results of this study will provide more information about the investigational drug and whether it could one day be approved to treat MDD when combined with antidepressant treatment.
