(note: Patent foramen ovale or a bicuspid valve are is not considered exclusionary, but may be associated with the following diseases, which are exclusionary: coarctation of the aorta, Turner syndrome, supravalvular aortic stenosis, subvalvular aortic stenosis, patent ductus arteriosus, Sinus of Valsalva aneurysm, ventricular septal defect, Shone's complex, ascending aortic aneurysm, Loeys-Dietz syndrome, ACTA2 mutation familial thoracic aortic aneurysm syndrome, and MAT2A mutation familial thoracic aortic aneurysm syndrome).~* Subject has current or recent history of Anorexia Nervosa, bulimia, or depression within the prior year that required medical treatment or psychological treatment for a duration greater than 1 month.~* Subjects who are currently on CBD/THC or any MMJ or those who have tested positive urine tetrahydrocannabinol (THC) Panel or whole blood cannabidiol (CBD).~* Subject has participated in another clinical trial within the past 30 days (calculated from that study's last scheduled visit).~* Subject is at imminent risk of self-harm or harm to others, in the investigator's opinion, based on clinical interview.~* Subject has a current or past history of glaucoma.~* Subject is receiving concomitant therapy with: centrally-acting anorectic agents; monoamine-oxidase inhibitors; any centrally-acting compound with clinically appreciable amount of serotonin agonist or antagonist properties, including serotonin reuptake inhibition; atomoxetine, or other centrally-acting noradrenergic agonist; or cyproheptadine. (see appendix 1)~* Subject has moderate or severe hepatic impairment.

Study Arms:
- Fenfluramine Hydrochloride (Type: EXPERIMENTAL): Study medication will be administered as equal doses twice a day in the morning and in the evening approximately 12 hours apart.~Patients will first be titrated over 14 days to a dose of ZX008 0.8 mg/kg/day (maximum dose 30 mg/d).~After completion of the Titration Period, patients will continue to receive the ZX008 0.8 mg/kg/day dose and be treated for an additional 12 weeks (Maintenance Period). Study medication will continue to be administered twice a day in the morning and in the evening, approximately 12 hours apart.~After completion of the Maintenance Period, patients will enter the Taper Period, where they will decrease from 0.8 mg/kg twice a day to a dose of 0.4 mg/kg twice a day (maximum 30 mg/day). After 4 days at this dose level, patients will decrease their dose to 0.2 mg/kg/day. On day 9 of the Taper Period, all participants will stop taking study medication.

Based on this trial design, predict the completion outcome and termination type (if applicable).
