New depression drug SP-101 enters first human safety trial

NCT ID NCT07334249

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 1 trial is the first time SP-101 is being tested in humans. It will enroll 80 healthy adults to check the drug's safety, tolerability, and how the body processes it. SP-101 works by blocking NMDA receptors in the brain, a different approach from standard antidepressants. The study does not yet test if the drug works for depression.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

SP-101 (a drug that blocks NMDA receptors in the brain)

What this could lead to

If successful, this could lead to a new treatment option for major depressive disorder, especially for people who don't respond to current antidepressants.

What could go wrong

This is a very early Phase 1 trial in healthy volunteers, not patients. It only tests safety and dosing, not whether SP-101 actually helps depression. Many drugs fail at this stage.
