Vanda reported positive topline Phase III results for HETLIOZ in delayed sleep-wake phase disorder; results were announced today.
The trial showed patients on HETLIOZ were more likely to shift sleep earlier than those on placebo.
Vanda plans to discuss the data with the FDA, then file a supplemental NDA to add the new indication.
If cleared, HETLIOZ would become the first FDA-indicated drug for delayed sleep-wake phase disorder.
Safety over the controlled treatment period was consistent with the existing HETLIOZ label, with no new safety issues flagged.
