(NYSE and TASE: TEVA), today announced new data for ecopipam, a first-in-class investigational selective D1 (dopamine) receptor antagonist for the treatment of pediatric patients with Tourette syndrome. Presented at the International Congress of Parkinson’s Disease and Movement Disorders (MDS) in Seoul, South Korea (October 4–8, 2026), the data include a post hoc analysis of safety and efficacy during the initial 8 weeks of treatment with ecopipam, long-term efficacy and safety from an interim analysis of an ongoing open-label extension (OLE) study, post hoc subgroup analyses and preclinical receptor selectivity findings.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

Please try again“Tourette syndrome is a complex neurodevelopmental disorder that presents significant daily challenges for children and their families,” said Eric Hughes, M.D., Ph.D., Executive Vice President, Global R&D and Chief Medical Officer of Teva. “These promising new data for ecopipam reinforce our confidence in its potential in pediatric Tourette syndrome care. If approved, ecopipam would be the first new therapy for Tourette syndrome in more than 10 years and the first with a novel mechanism of action in more than 50 years.”This advertisement has not loaded yet, but your article continues below.Key Findings from Studies Include:Tic Severity Reduction Observed Within Two Months of Treatment: In a pooled post hoc analysis of 292 patients across Phase 2b and Phase 3 trials, a clinically meaningful improvement in the Yale Global Tic Severity Scale Total Tic Score (YGTSS-TTS) (score ≥25%) was observed in 69.8% of participants within the first eight weeks of treatment with ecopipam. The most commonly reported adverse events (AEs) were somnolence and headache, and the most commonly reported cross-trial AEs were most often observed within the first eight weeks of ecopipam exposure.Clinically Meaningful Reduction in Tic Severity Sustained >1 year: An interim analysis of an ongoing 36-month OLE study included patients who completed the phase 3 study and the phase 2b OLE study receiving ecopipam titrated over 3-4 weeks then maintained at a target dose for up to 36 months. The study evaluated 118 children, adolescents and adults with Tourette syndrome who received at least one dose of ecopipam (median treatment exposure of 14.9 months). Ecopipam maintained clinically meaningful tic suppression through 18 months according to the YGTSS-TTS. The most commonly reported AEs were nasopharyngitis, upper respiratory tract infection, anxiety, diarrhea, influenza, pyrexia and insomnia.Co-Occurring Psychiatric Conditions Did Not Impact Efficacy or Safety of Ecopipam: A post hoc analysis evaluated 216 participants (aged ≥6 years) from the Phase 3 trial, comparing outcomes between those with (n=129) and without (n=87) common co-occurring psychiatric conditions, including ADHD, OCD, anxiety and depression. During the 12-week open-label period, the presence of co-occurring conditions did not negatively impact reductions in tic severity, with mean YGTSS-TTS score reductions consistent across participants with ≥1 co-occurring conditions and those without. Overall safety and tolerability profiles were similarly consistent between both groups.This advertisement has not loaded yet.This advertisement has not loaded yet, but your article continues below.“Many children with Tourette syndrome do not receive treatment, and among those who do, treatment is often discontinued within a year because symptoms remain inadequately controlled or side effects become difficult to tolerate,” said Donald L. Gilbert, M.D., M.S., Pediatric Movement Disorders and Tourette Syndrome Specialist, Division of Neurology, Cincinnati Children’s Hospital Medical Center. “Children living with Tourette syndrome urgently need treatment options that work rapidly, remain effective over time and have a demonstrated tolerability profile. These findings are encouraging because they suggest that, if approved, ecopipam may offer patients and families a meaningful new option.”About Tourette SyndromeTourette syndrome is a chronic neuro-developmental disorder characterized by involuntary motor and vocal tics beginning in childhood, often between 5 and 10 years of age.2 For people living with Tourette syndrome, symptoms can be frequent, visible and disruptive, affecting everyday life.2About Ecopipam and Its Clinical ProgramEcopipam is a first-in-class investigational therapy designed to block dopamine signaling at the D1 receptor. D1 receptor hypersensitivity may contribute to repetitive and compulsive behaviors associated with Tourette syndrome.This advertisement has not loaded yet, but your article continues below.Ecopipam was granted Priority Review by the FDA with Orphan Drug designation for the treatment of pediatric patients with Tourette syndrome. Orphan Drug designation is reserved for patient populations of 200,000 or fewer.The D1AMOND Phase 2b Trial was a 12-week randomized, double-blind, placebo-controlled trial that studied 153 pediatric participants across 68 sites in North America and Europe. The primary efficacy endpoint was the change in the YGTSS-TTS, i.e., sum of the motor and vocal tic scores, from baseline to end of therapy.3 The associated Phase 2b open-label extension enrolled 121 pediatric subjects from the Phase 2b trial and followed them for up to 12 months’ duration to evaluate the long-term safety and tolerability of ecopipam.4 The subsequent D1AMOND Phase 3 Trial was a double-blind, placebo-controlled, randomized withdrawal trial enrolling a total of 216 pediatric and adult participants into an open-label stabilization period and randomizing 104 participants (90 pediatric, 14 adult) across 77 sites in North America and Europe. The objective of this study was to evaluate the maintenance of efficacy of ecopipam in pediatric and adult responders utilizing the YGTSS-TTS change from randomization or increased Tourette-specific care to determine relapse.5 While this Phase 3 trial included adult participants, the accepted NDA and resulting indication sought by Teva are exclusively for pediatric patients.This advertisement has not loaded yet, but your article continues below.About TevaTeva Pharmaceutical Industries Ltd.
