Brief description of study

When you’re living with Major Depressive Disorder (MDD), you know all too well how challenging everyday life can become. The struggle to find effective relief can lead to feelings of hopelessness and frustration.  But there is hope. 

This new research study is looking at a fast-acting medication designed to help improve symptoms more quickly than traditional treatments. By participating, you can play a vital role in discovering a potential breakthrough for yourself and others who are battling this condition. 

Detailed description of study

What you can expect:

First, there is a Screening Phase, where doctors will make sure it is safe for you to take part. This may include stopping some of your current medicines if needed.

Next, you will enter a 2-week treatment phase. During this time, neither you nor the study team will know which treatment you are receiving. You will either:

  • Get the study medicine two times a week with “dummy” pills (placebos) on the other days, or
  • Get only placebo pills every day.

After the treatment phase, there will be a 2-week period without antidepressants. This helps researchers see how long the effects of the treatment last and check on safety.

Finally, you will have a follow-up phase with regular care that may last up to 6 weeks.

Eligibility of study

You may be eligible for this study if you meet the following criteria:

  • Conditions: Major depressive disorder, MDD
  • Age: 18 years - 64 years
