Centessa Pharmaceuticals Announces Preclinical Data Supporting ORX750’s Potential as a Best-in-Class Oral OX2R Agonist for the Treatment of Narcolepsy and Other Sleep-Wake Disorders
BOSTON and LONDON, Oct. 25, 2023 (GLOBE NEWSWIRE) -- Centessa Pharmaceuticals plc (Nasdaq: CNTA), a clinical-stage pharmaceutical company that aims to discover and develop medicines that are transformational for patients, today announced a robust set of new preclinical data from in vivo and in vitro studies of its investigational, novel orexin receptor 2 (OX2R) agonist, ORX750, that support its potential best-in-class profile for the treatment of narcolepsy and other sleep-wake disorders.
- “The preclinical data showed ORX750 achieved maximal wake times and suppressed cataplexy at 0.1 mg/kg, the lowest oral dose tested in the DTA mouse model.
- Notably, this activity was observed in both the DTA and Atax mouse models that recapitulate NT1 symptoms in humans.
- Fluorescent imaging plate reader (FLIPR) assay with Chinese hamster ovary (CHO) cells stably expressing recombinant human OX1R or OX2R; OXA EC50 at hOX2R = 0.035 nM.
- As measured by electroencephalogram (EEG) and electromyogram (EMG) with concurrent video in DTA and Atax mouse models.
