Can an antipsychotic restore feelings in people with depression?
NCT ID NCT07824206
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers test whether adding lumateperone to ongoing antidepressant treatment reduces emotional blunting in adults with major depressive disorder. Emotional blunting means feeling numb or unable to experience pleasure or sadness. Thirty participants who score high on the Oxford Depression Questionnaire receive lumateperone 42 mg once daily for eight weeks. The trial measures changes in their emotional blunting score to see if the drug helps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lumateperone, an antipsychotic drug added to ongoing antidepressant treatment
- What this could lead to
- If it works, adding lumateperone could give doctors a way to help people with depression who feel emotionally numb on standard antidepressants.
- What could go wrong
- This is a small Phase 4 trial with 30 participants, so results may not hold up in larger groups. Lumateperone can cause side effects like drowsiness, and emotional blunting may have causes this drug cannot address.
