Phase III Open-Label, Randomized Clinical Trial of Epidermal Growth Factor and Growth Hormone Releasing Hexapeptide in Acute Ischemic Stroke.

Editor's note

This trial studied GHRP-6 in combination with epidermal growth factor, so its effects cannot be isolated to the peptide alone. The study missed its primary endpoint, with benefit seen only in a small severe-stroke subgroup and an open-label design that limits confidence. A genuine but preliminary signal warranting further study.

Plain-language abstract

In this phase III open-label trial, combined epidermal growth factor and GHRP-6 for acute ischemic stroke did not improve overall disability at six months, though a pre-specified severe-stroke subgroup showed reduced disability and mortality.
