Could a depression drug fight prostate cancer?

NCT ID NCT02217709

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tested phenelzine sulfate (Nardil), an antidepressant, in 26 men with prostate cancer that returned after initial treatment but hadn't spread. The goal was to see if the drug could lower PSA levels, a marker of cancer activity. Researchers measured how many patients had a 50% or 30% drop in PSA after 12 weeks of treatment.

Active substance

phenelzine sulfate (Nardil), an antidepressant drug

What this could lead to

If it works, this could point toward a new treatment option for men with recurrent prostate cancer that hasn't spread.

What could go wrong

This is a small, early-phase trial with only 26 participants, so results may not apply to everyone. The drug is an antidepressant, and its cancer-fighting effects are uncertain.
