To assess the magnitude and duration of reduction in RNS recorded Detections and Long
Episodes following intranasal administration of Valtoco®. All participants will have been
implanted and treated with an RNS system for clinical purposes and regularly upload Detection
and Long Episode data on a regular basis as part of regular clinical treatment. Participants
will come to the clinic and be administered a single dose of Valtoco® via nasal spray. RNS
recorded Detections and Long Episodes before and after Valtoco® administration will be
compared. This is a pilot study, so all outcomes are exploratory.
