US regulatory status & drug development

Drugs@FDA lists no NDA, BLA or ANDA with examorelin as an active ingredient (names searched: EXAMORELIN, HEXARELIN; checked October 7, 2026). Research-labelled Hexarelin listings are not FDA-approved drugs.

An FDA approval covers a defined medicine, formulation and labelled use. It does not extend to research-labelled material sold under the same compound name. Identity basis: INN examorelin and the name hexarelin were searched.

Drug development record (ChEMBL)

Harmonized drug-development record from ChEMBL. The highest clinical stage is the furthest stage reached, as recorded by ChEMBL; it can lag regulatory approvals, and it is not an approval of a research-supplier product.

Registered clinical trials

Studies registered on ClinicalTrials.gov that list Hexarelin as an intervention. Studies that only measure the molecule as a biomarker, or use it only as a comparator or background arm for another drug, are excluded. A registration describes a planned or completed protocol; it does not report a result. Active studies are listed first.

No registered study naming this compound was matched. This is a documented gap in registry coverage, not proof that no study exists.
