Could a drug tame excess cortisol in a common hormone disorder?

NCT ID NCT07138274

First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time

Summary

This study tests whether the drug metyrapone can safely lower cortisol levels in people with mild autonomous cortisol secretion (MACS), a condition where the adrenal glands produce too much cortisol. Participants will receive either metyrapone or a placebo for a short period, and researchers will measure changes in hormone ratios and daily cortisol patterns. The goal is to see if metyrapone can help control the hormone imbalance and improve health outcomes.

What this could mean

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

Active substance

metyrapone

What this could lead to

If successful, metyrapone could offer a way to manage cortisol levels in people with MACS, potentially reducing related health risks.

What could go wrong

This is an early Phase 2 study with only 90 participants, so results may not apply broadly. Metyrapone can cause side effects like nausea or dizziness.
