Twice-Yearly shot could halt early puberty in kids

NCT ID NCT05493709

Summary

This phase 3 trial tests a new formulation of leuprolide (FP-001) given as two injections six months apart in 93 children with central precocious puberty—a condition where puberty starts too early. The goal is to see if it can safely pause puberty by keeping hormone levels low. If it works, it could mean fewer injections for children needing treatment.

What this could mean

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

Active substance

Leuprolide (a hormone blocker)

What this could lead to

If successful, this could provide a treatment that pauses early puberty with just two injections per year, reducing the need for more frequent shots.

What could go wrong

This is a single-arm, open-label study with no placebo group, so results may be less definitive. The treatment is not a cure—it only delays puberty while active, and long-term effects are still being studied.
