Registration Number
NCT06021522
Lead Sponsor
Emalex Biosciences Inc.
Brief Summary

The primary objective of this study is to evaluate the long-term safety and tolerability of ecopipam tablets in children (greater than or equal to \[\>=\] 6 and less than \[\<\] 12 years of age), adolescents (\>=12 and \<18 years of age), and adults (\>=18 years of age) with Tourette's Syndrome (TS).

Detailed Description

This study is to evaluate the long-term safety and tolerability of ecopipam tablets in eligible participants. The eligible participants will be entered into a treatment period and start a 4-week titration phase to achieve a target steady-state dose of 1.8 milligram per kilogram per day (mg/kg/day) ecopipam (2 mg/kg/day dose of ecopipam HCl). During the 4-week titration phase ecopipam will be dispensed following weight bands before reaching their respective maintenance dose until end of the treatment. Safety assessment will be conducted at baseline visit and at all treatment visits (Months 1-12, 15, 18, 21 and 24). Safety follow up visits will be conducted 7 and 14 days and a follow up phone call will be conducted 30 days after the last dose of ecopipam.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)Baseline up to Month 24

An adverse event (AE) is defined as any untoward medical occurrence in a subject administered a study drug and which does not necessarily have a causal relationship with this treatment. A TEAE is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered casually related to the product.
