About the SOLEO Study 

We understand how important it is for those who suffer from depression to find an effective treatment. Different types of oral antidepressants work in different ways. 

For reasons that medical scientists do not fully understand, the degree of symptom relief from various oral antidepressants can differ from patient to patient. 

Many patients find that while they get some symptom relief from the antidepressants they have tried, the relief is simply not sufficient for them.

The SOLEO study is currently enrolling subjects suffering from major depressive disorder and is designed to assess the safety and efficacy of the study drug for people who have tried other treatments for major depressive disorder without sufficient improvement.

Study Drug Information

In this research study, we are evaluating a drug called CLE-100. It is a tablet taken once daily in addition to your current oral antidepressant. The study drug is an investigational therapy, which means it is still being tested in clinical research studies. It has not been approved by the US Food and Drug Administration (FDA) or other Health Authorities to be prescribed for treatment.

If you decide to join the SOLEO study, you will be randomly assigned (like the flip of a coin) to receive either the study drug or placebo (no active ingredients) for 4 weeks after which all participants will be offered the opportunity to receive the active study drug (CLE-100) for a period of 6 months at no cost.
