ClinConnect Summary

This clinical trial is studying a new treatment called ALTO-300 for people with moderate to severe major depressive disorder (MDD). The goal is to find out how effective ALTO-300 is compared to a placebo (a non-active treatment) when used alongside a regular antidepressant. If you or someone you know has been diagnosed with MDD and is currently taking a specific type of antidepressant for at least six weeks, you might be eligible to participate in this study.

To join, participants must be aged between 18 and 75 years and should not be pregnant or breastfeeding. They should also be willing to follow the study guidelines. However, people with certain conditions, like unstable medical issues, bipolar disorder, or those using sleep medications every night, cannot take part. Those who join will have regular check-ins to assess their progress and how they respond to the treatment. This study is currently recruiting participants, so if you think you might be interested, it could be a great opportunity to help advance treatment for depression.
