Plain-Language Summary
Plain-language reading of the public trial registries.
In short
- Very little human research on Nafarelin has been registered.
- 11 registered studies in total.
- 3 are still enrolling people, so this is active research, not just history.
What kind of research
- 10 studies actually gave the peptide to volunteers and measured what happened. This is the kind of study that can show whether something works.
- About 1,966 people took part in those.
- A further 1 study only looked at records of people already taking it. These are counted separately because nobody was given the peptide for the study, so they cannot prove cause and effect.
How far along it is
- 4 trials have reached phase 3 or 4 — the large, late-stage trials regulators rely on to approve a drug.
- 3 have published results in the medical literature that anyone can read.
- The research spans 6 countries.
A registered trial is a plan, not a result. Registration means a study was declared in advance; it says nothing about whether the peptide worked, and a trial can be registered and then abandoned.

Sources: ClinicalTrials.gov, the EU Clinical Trials Information System and ISRCTN, deduplicated so a study registered in more than one registry is counted once. A study is listed when Nafarelin is named as an intervention. A registered trial is a plan, not a result — registration says nothing about whether the peptide worked.
