Posiphen® is in clinical development as an oral treatment for Alzheimer's disease (AD). It is a small orally active compound with high blood brain barrier permeability, which lowers amyloid precursor protein (APP) levels. Posiphen reduces the rate of synthesis of APP in cell cultures, normal, transgenic and trisomic mice.

APP is cleaved into a number of toxic peptides, including Aβ42, which is cleaved from the middle while the others are cleaved from the N- and C- terminal ends. These peptides attack multiple pathways of neuronal cell life leading to synaptic loss and nerve cell death. This degeneration of the brain induces dysfunction, neuroinflammation and leads to cognitive impairment and neurodegeneration.

QR conducted a trial in patients with mild cognitive impairment (MCI) to confirm Posiphen's mechanism of action in humans and correlate it with the pharmacokinetics of the compound and its metabolites in CSF and plasma. Posiphen lowers levels of APP and tau by about 40%, approaching the levels found in healthy volunteers.
