Efficacy evidence
OX/ataxin-3 transgenic NT1 mouse model (loss of orexin neurons): increased wakefulness
“The effect of oveporexton on wakefulness during the sleep phase was also demonstrated in OX/ataxin-3 transgenic mice (a NT1 mouse model in which the transgene selectively eliminates orexin producing neurons in the hypothalamus) and their non-transgenic WT littermates.”
✓ VerifiedFDA multi-discipline review, p. 49Source ↗
Why that model
Monkeys added because mice are nocturnal; diurnal monkeys have a sleep/wake structure closer to humans
“Because mice are nocturnal animals with a polyphasic sleep/wake structure, studies were also conducted in cynomolgus monkeys which are diurnal and have a monophasic sleep/wake structure more analogous to humans.”
✓ VerifiedFDA multi-discipline review, p. 49Source ↗
Reviewer's view of the efficacy data
FDA: OX2R-selective agonist that produced wakefulness and ameliorated narcolepsy-like features in relevant animal models
“Overall, the primary pharmacology studies demonstrated that oveporexton acts as a OX2R agonist, with much greater selectively for OX2R versus OXR1, and is capable of producing wakefulness and ameliorating narcolepsy-like characteristics in relevant animal models.”
