Piromelatine (Neu-P11)

Piromelatine is a novel compound under development for sleep and cognition in treatment of insomnia and Alzheimer’s Disease.
Piromelatine is an agonist of melatonin receptors and serotonin 5-HT-1A and 5-HT-1D receptors. Through its action at MT receptors, Piromelatine may improve circadian rhythms control, metabolism and sleep and through the serotonergic mechanism improve memory and mood. MT and 5HT1a mechanisms synergistically enhance neurogenesis and neuroprotection.

This multi-targeted drug candidate has already demonstrated efficacy and safety in a Phase II clinical trial in patients with primary insomnia. Based on preclinical studies in cell and animal model of the disease, Neurim intends to study the efficacy and safety of Piromelatine in patients with mild to moderate Alzheimer’s Disease. Piromelatine’s multi-targeted mechanism of action is different from that of Alzheimer’s Disease medications and from investigational failed drugs. Read more


Neu-P12 is a multi-facetted new chemical entity with analgesic potential.
Its mechanism of action involves inhibition of human Nav1.7 sodium channels and TRPV1 non-selective cation channels that are widely expressed in skin tissues, and peripheral sensory nerve fibers. Neu-P12 does not interact with COX 1 or 2 or opioid receptors, suggesting a selective mode of action. It demonstrates a good potential for the treatment of inflammatory and pain in three different and relevant animal pain models.
Neu-P12 is intended as a therapy for neuropathic pain and is currently in Phase I at First in Human stage.

Products in Preclinical Phase


Neu-240 is a potent and selective uncompetitive NMDA receptor modulator aimed at improving motor control. Neu-240 is a derivative of Neu-120, intended for use as adjunct therapy to levodopa in patients with Parkinson’s disease and is currently at the preclinical stage.
