Ecopipam Tablets to Study Tourette Syndrome in Children and Adolescents - Open Label Extension (D1AMOND)

This is an international, multicenter, open-label, long term extension study evaluating the safety of ecopipam tablets for the treatment of pediatric subjects (aged ≥6 to ≤18 years at Baseline) with Tourette Syndrome. Subjects who completed the Phase 2b, randomized, double-blind, efficacy and safety study (EBS-101-CL-001) without major reportable protocol deviations, and who meet all the inclusion/exclusion criteria for this study will be eligible to participate in this study. All subjects who provide informed consent and participate in this study will be titrated to a target dose of 2 mg/kg/day. All participants rolling over from the Phase 2b double-blind efficacy and safety study will be tapered off of study medication to maintain the blind from that study. Subjects will complete study visits every month for 1 year. Follow Up visits will be conducted 7 and 14 days after the last dose of study medication and a Follow Up phone call will be conducted 30 days after the last dose of study medication.

Inclusion Criteria:

• Subjects must have completed the EBS-101-CL-001 study through the Day 14 Follow Up Visit within the last 30 days (or longer with permission of the medical monitor) without a major reportable protocol deviation and must be someone the Investigator feels would benefit from continued participation.

Exclusion Criteria:

• Certain mood or psychiatric disorders (i.e., dementia, bipolar disorder, schizophrenia, major depressive disorder).
• Unstable medical illness or clinically significant lab abnormalities.
• Risk of suicide.
• Pregnant or lactating women.
• Moderate to severe renal insufficiency.
• Positive urine drug screen.
• Certain medications that would lead to drug interactions.
