Teva Announces Long Term Efficacy and Safety of Deutetrabenazine in European Patients with Debilitating Movement Disorder Tardive Dyskinesia

Rhea-AI Summary

Teva Pharmaceutical Industries (NYSE and TASE: TEVA) announced positive results from a new analysis of the European cohort in the RIM-TD open-label extension study. The study showed that deutetrabenazine treatment for Tardive Dyskinesia (TD) patients led to long-term improvement of symptoms over three years. TD is an involuntary movement disorder affecting 15%-25% of patients taking antipsychotic medications.

Key findings presented at the European College of Neuropsychopharmacology Congress include:

• 65% of patients achieved treatment success on the Clinical Global Impression of Change (CGIC)
• 56% of patients achieved treatment success on the Patient Global Impression of Change (PGIC)
• Deutetrabenazine was generally well-tolerated

The study highlights the potential of deutetrabenazine as an effective treatment option for TD, addressing a high unmet medical need in Europe where treatment options are approved.

TEL AVIV, Israel, Sept. 23, 2024 (GLOBE NEWSWIRE) -- Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) announced today that a new analysis from the European cohort of the RIM-TD open-label extension (OLE) study revealed that deutetrabenazine treatment of patients with Tardive Dyskinesia (TD) was associated with long term improvement of TD symptoms. The improvement in symptoms was sustained throughout the three-year study, and deutetrabenazine was well tolerated.¹ The data were presented at the European College of Neuropsychopharmacology (ECNP) annual congress in Milan.

TD is a stigmatising and debilitating involuntary movement disorder characterised by repetitive movements of the tongue, lower face, jaw, and limbs, which develops in around 15%-25% of patients receiving antipsychotic medications for conditions such as schizophrenia, bipolar disorder, and major depressive disorder.^2,3

TD usually appears after 1-2 years of taking antipsychotic treatment and has a considerable impact on a patients’ functioning and quality of life.⁴ The condition has a high unmet medical need as limited treatment options are approved in Europe.⁵   

RIM-TD (Reducing Involuntary Movements in Participants with Tardive Dyskinesia) is a three-year study which enrolled patients who had completed one of the two pivotal deutetrabenazine phase 3 studies, ARM-TD⁶ and AIM-TD.⁷ Whilst RIM-TD was conducted in both the United States and Europe, the post hoc subgroup analysis focused on patients from the European countries.¹

Treatment success was defined as ‘much improved’ or ‘very much improved’ on the Clinical Global Impression of Change (CGIC) or Patient Global Impression of Change (PGIC). The majority of patients achieved treatment success with 65% of patients for CGIC and 56% for PGIC. Deutetrabenazine was generally well tolerated, regardless of which arm of the two Phase 3 trials (treatment or placebo) the patients had previously been treated in.¹

Co-author and presenter of the data, Dr Krzysztof Duma, Associate Medical Director, Teva Pharmaceuticals Europe, said, “Tardive Dyskinesia is a complex disorder that is difficult to treat and remains broadly underdiagnosed. Treating this condition still often results in dose reductions of antipsychotic medication that can impact the underlying psychiatric condition and lead to higher hospitalisation rates. The positive outcome of the study in the European cohort is similar to what we have observed in the overall and US population and gives us further evidence that deutetrabenazine can provide an effective treatment option.”

“Tardive Dyskinesia can cause great distress to patients and may be correlated with more severe symptoms and worse outcomes in patients with schizophrenia,” said Pinar Kokturk, M.D. Vice President & Head of Medical Affairs Europe at Teva. “Management of Tardive Dyskinesia is sadly not optimal. Across Europe, guidelines for the management of TD are scarce or missing and there is no standard of care. Despite several treatments used in Europe, the majority have poor clinical evidence and are used off-label and there remains a high unmet need in the treatment of TD. This must change.”

Deutetrabenazine has now been evaluated in ARM-TD, AIM-TD as well as RIM-TD, all of which demonstrated that the treatment provides rapid, sustained, and clinically meaningful improvements in motor function in patients with Tardive Dyskinesia.^1,6,7

Deutetrabenazine is already approved in the United States and in a number of other markets worldwide.⁸

NOTES TO EDITORS

About Tardive Dyskinesia (TD)
Tardive dyskinesia (TD) is a highly debilitating, chronic movement disorder that affects around 15% to 25% of those who take certain antipsychotic treatments and is characterised by involuntary, abnormal and repetitive movements of the face, torso, and/or other body parts, which may be highly disruptive and can significantly, negatively impact individuals’ quality of life and functioning. Current treatments in Europe are not well evidenced and dose reduction, discontinuation or switching antipsychotic treatment is unlikely to reverse TD. This can lead to suboptimal management of the underlying condition and an increased risk of relapse.

About Deutetrabenazine
Deutetrabenazine is a selective reversible vesicular monoamine transporter type 2 (VMAT2) inhibitor. VMAT2 inhibitors are agents that cause a depletion of neuroactive peptides such as dopamine in nerve terminals and are used to treat conditions such as dyskinesias due to some antipsychotic medications.
