Can a new pill for enlarged prostate match the original?
NCT ID NCT07722871
First seen Jul 23, 2026 · Last updated Jul 28, 2026 · Updated 3 times
Summary
This trial is testing whether a new formulation of a drug for benign prostatic hyperplasia (enlarged prostate) works the same as the existing version. Healthy adult male volunteers receive a single dose of each formulation after a meal, and researchers compare how much drug gets into the bloodstream. The goal is to see if the new version can be used as an equivalent alternative.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a new formulation of a drug for benign prostatic hyperplasia (AD-116A) compared to the original (AD-1161)
- What this could lead to
- If the new formulation is shown to be equivalent, it could offer an alternative treatment option for enlarged prostate.
- What could go wrong
- This is an early-phase study in healthy volunteers, not patients, so results may not predict real-world effectiveness or safety.
