Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Treatment-Emergent Adverse Events (TEAEs)

    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.

    Baseline up to Month 24

Study Arms (1)

Ecopipam 1.8 mg/kg/day

EXPERIMENTAL

Ecopipam tablets will be administered orally (PO) once daily in the evening without regard to meals at concentrations 11.2, 22.4, 33.6, 44.8, 67.2 and 89.6 milligrams (mg) containing 12.5, 25, 37.5, 50, 75 and 100 mg ecopipam HCl, respectively in 4-week titration phase to achieve a target dose of 1.8 milligram per kilogram per day (mg/kg/day) ecopipam (2 mg/kg/day ecopipam HCl). Participants will be evaluated for safety at each baseline visit and at all treatment visits up to 24 months and at follow up visits at 7 and 14 days after last dose of ecopipam.

Drug: Ecopipam

Interventions

Selective dopamine D1 and D5 receptor antagonist

Also known as: Ecopipam Hydrochloride
Ecopipam 1.8 mg/kg/day

  • Participants receiving any other medication to treat motor or vocal tics and anti-depressant or anti-anxiety medications.
  • Risk of suicide as per PI judgement
  • Pregnant or lactating women
