Centessa Pharmaceuticals' Therapy Portfolio Targets Sleep-Wake Disorders

Centessa has been developing a portfolio of orexin receptor 2 (OX2R) agonists, a class of therapies targeting the brain mechanisms that regulate wakefulness. Its lead candidate, cleminorexton, has shown encouraging results in mid-stage trials for conditions such as narcolepsy and idiopathic hypersomnia. 

The company is also advancing earlier-stage programs that could address a wider spectrum of neurological and psychiatric disorders.

"Orexin receptor biology represents one of the most compelling mechanistic opportunities in neuroscience as a direct intervention on the master switch of the sleep-wake cycle.”
