Davunetide is the first neuroprotective peptide in its class, and has preclinical evidence for neuroprotective, neurotrophic and cognitive protective properties. Davunetide has also been shown to prevent apoptosis or programmed-cell death in a range of in vitro and in vivo models by promoting microtubule stabilization. Potential clinical uses of davunetide include neurodegenerative disorders such as Alzheimer's disease (AD), progressive supranuclear palsy (PSP), frontotemporal dementia (FTD) or cognitive impairment in other diseases such as schizophrenia where microtubule structure and function is known to be impaired. The nonclinical and clinical safety of davunetide is reviewed here in detail. Pre-clinical toxicology studies in rats and dogs using the maximum feasible dose of davunetide provide strong evidence that davunetide is well-tolerated. Similarly, data from 10 separate clinical trials of davunetide, investigating safety and efficacy provide evidence that davunetide is generally safe and well-tolerated, and has shown some signs of clinical efficacy.
