Nxera Pharma Advances Innovative OX2R Agonist, ORX750, Forward
Positive Clinical Data for ORX750 in Sleep Disorders
In an exciting development for sleep disorder treatment, Centessa Pharmaceuticals recently shared interim Phase 1 clinical data, highlighting the progress made with its novel orexin receptor 2 (OX2R) agonist, ORX750. This investigational drug demonstrated statistically significant improvements in sleep latency for acutely sleep-deprived healthy individuals.
Impressive Results from Clinical Trials
During the trials, ORX750 produced clinically meaningful results, showcasing improvements in sleep latency, particularly with the two lowest doses tested (1.0 mg and 2.5 mg). Notably, the 2.5 mg dose facilitated a remarkable restoration of normative wakefulness, yielding an impressive mean sleep latency of 32 minutes during the Maintenance of Wakefulness Test (MWT).
Next Steps in Development
Following these successful results, Centessa plans to swiftly advance ORX750 into Phase 2 studies, targeting patients with narcolepsy types 1 and 2, as well as idiopathic hypersomnia. This phase is set to commence in the near future, with expectations to begin in the latter part of 2024.
Safety and Tolerability Analysis
One of the standout features of ORX750 is its favorable safety and tolerability profile. Clinical observations revealed no significant on-target adverse events commonly noted with other OX2R agonists, including hepatotoxicity or visual disturbances, across all tested dose levels.
