Yale study tests if a pep talk boosts depression drug – but only one person joined
NCT ID NCT05910775
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aimed to see if giving patients extra encouragement before and after esketamine treatment could improve their depression symptoms. Researchers planned to compare a group that received a positive presentation and follow-up session with a group that did not. However, the trial was terminated after enrolling only one participant, so no meaningful conclusions can be drawn.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- esketamine
- What this could lead to
- If successful, this could show that adding simple encouragement sessions makes esketamine work better for depression.
- What could go wrong
- The trial was terminated with only 1 participant, so results are not reliable. It is too early to draw any conclusions.
