ClinConnect Summary
This clinical trial is studying a medication called Lumateperone to see if it can help people with Major Depressive Disorder (MDD) who aren't getting enough relief from their current antidepressant treatments. The study is looking for adults aged 18 to 65 who have been experiencing depression for at least 12 weeks but not more than 18 months, and who have not responded well to two or more antidepressant medications. Participants will be randomly assigned to receive either Lumateperone or a placebo (a pill that looks like the medication but has no active ingredients) to compare how well they work.
If you or someone you know is interested in participating, it's important to know that this study is currently recruiting patients. Eligible participants will need to have moderate to severe symptoms of depression and must be taking a stable dose of antidepressants for at least six weeks without seeing significant improvement. Throughout the trial, participants will attend regular visits with the study team to monitor their progress and any side effects. This research is essential for finding better treatment options for those struggling with depression, and your involvement could help others in the future.
