Neurocrine's VYKAT XR Shows Durable Benefits in Prader-Willi Syndrome Trials

Event summary

  • Neurocrine's VYKAT XR demonstrated durable improvements in hyperphagia and behavioral symptoms in Prader-Willi syndrome (PWS) patients after a 16-week randomized withdrawal period.
  • Participants who resumed VYKAT XR showed marked improvements in hyperphagia by Week 13, with benefits continuing through 2 years.
  • VYKAT XR-treated participants showed statistically significant and sustained improvements in hyperphagia and behavioral symptoms compared to real-world data from the PATH for PWS Natural History Study over three years.
  • The Phase 3 development program included a 13-week randomized study, a 2-4 year open-label extension, a 16-week randomized withdrawal period, and a long-term extension study enrolling 77 participants.

The big picture

Neurocrine's VYKAT XR represents a significant advancement in the treatment of Prader-Willi syndrome, a rare genetic disorder characterized by hyperphagia and behavioral symptoms. The durable improvements observed in clinical trials position VYKAT XR as a potential long-term solution for a condition with limited therapeutic options. The data reinforces Neurocrine's strategy of developing treatments for under-addressed neurological and psychiatric disorders, leveraging its expertise in neuroscience.
