PRX-03140 is a partial agonist of the 5-HT4 receptor that is being developed by EPIX Pharmaceuticals for Alzheimer's disease. In vitro shows potent binding to 5-HT4 receptor and increased cAMP production in human embryonic kidney-293 cells expressing recombinant rat 5-HT(4) receptors. In the clinical trial, PRX-03140 was associated with a statistically significant improvement in the Alzheimer’s Disease Assessment Scale.
