TEL AVIV, Israel & PARSIPPANY, N.J.--(BUSINESS WIRE)-- Teva Pharmaceuticals, a U.S. affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA),today announced six poster abstracts across its neurology portfolio will be presented at the American Academy of Neurology (AAN) Annual Meeting on April 22-27, 2023. Abstracts include data for AUSTEDO (deutetrabenazine) tablets, as well as once-daily AUSTEDO XR (deutetrabenazine) extended-release tablets. AUSTEDO XR was recently approved by the FDA, as a once-daily formulation of AUSTEDO for adults living with tardive dyskinesia (TD) and chorea associated with Huntington’s disease (HD), which can be taken with or without food. It is expected to be commercially available later this year.
“Much of the data we’re presenting served as a foundation for the FDA’s recent approval of AUSTEDO XR,” said Eric Hughes, MD, PhD, Executive Vice President of R&D and Chief Medical Officer at Teva. “We’re excited clinicians will have the opportunity to better understand the potential of AUSTEDO XR as a once-daily option that can deliver the same therapeutic benefit as twice-daily AUSTEDO for adults living with TD and HD chorea.”
Notably, these presentations include new data from dose proportionality and bioequivalence studies, which supported the FDA approval of once-daily AUSTEDO XR extended-release tablets – demonstrating AUSTEDO XR is therapeutically equivalent to the currently marketed twice-daily AUSTEDO. Bioequivalence and relative bioavailability were established between the once-daily and twice-daily tablet formulations, with no new safety findings emerging. Additionally, dose proportional exposures were achieved for 6 mg, 12 mg and 24 mg deutetrabenazine dose strengths and AUSTEDO XR may be used across the full clinical dose range (6 mg – 48 mg).
Teva will also present real-world data showing people living with HD chorea who are taking antipsychotic medications with twice-daily AUSTEDO experienced improved motor signs. Additional abstracts from the Enroll-HD Global Registry and AJOVY® (fremanezumab-vfrm) will also be presented.
This year’s annual AAN meeting is being offered both in person and virtually. Abstracts can be accessed here.

About Tardive Dyskinesia (TD)
Tardive dyskinesia (TD) is a highly debilitating, chronic movement disorder that affects one in four people who take certain mental health treatments and is characterized by uncontrollable, abnormal, and repetitive movements of the face, torso, and/or other body parts, which may be disruptive and negatively impact individuals.
About Chorea Associated with Huntington’s Disease (HD)
Huntington’s disease (HD) is a fatal neurodegenerative disease characterized by uncoordinated and uncontrollable movements, cognitive deterioration and behavioral and/or psychological problems. Chorea – involuntary, random and sudden, twisting and/or writhing movements – is one of the most striking physical manifestations of Huntington’s disease and occurs in approximately 90% of patients. Chorea can have a significant impact on daily activities and progressively limit peoples’ lives.
About AUSTEDO XR Extended-Release Tablets and AUSTEDO Tablets
AUSTEDO is the first and only vesicular monoamine transporter 2 (VMAT2) inhibitor approved by the U.S. Food and Drug Administration in adults for the treatment of tardive dyskinesia and for the treatment of chorea associated with Huntington’s disease. AUSTEDO XR is the once-daily formulation of AUSTEDO. Safety and effectiveness in pediatric patients have not been established.
INDICATIONS AND USAGE
AUSTEDO® XR (deutetrabenazine) extended-release tablets and AUSTEDO® (deutetrabenazine) tablets are indicated in adults for the treatment of chorea associated with Huntington’s disease and for the treatment of tardive dyskinesia.
IMPORTANT SAFETY INFORMATION
Depression and Suicidality in Patients with Huntington’s Disease: AUSTEDO XR and AUSTEDO can increase the risk of depression and suicidal thoughts and behavior (suicidality) in patients with Huntington’s disease. Balance the risks of depression and suicidality with the clinical need for treatment of chorea. Closely monitor patients for the emergence or worsening of depression, suicidality, or unusual changes in behavior. Inform patients, their caregivers, and families of the risk of depression and suicidality and instruct them to report behaviors of concern promptly to the treating physician. Exercise caution when treating patients with a history of depression or prior suicide attempts or ideation. AUSTEDO XR and AUSTEDO are contraindicated in patients who are suicidal, and in patients with untreated or inadequately treated depression.
Contraindications: AUSTEDO XR and AUSTEDO are contraindicated in patients with Huntington’s disease who are suicidal, or have untreated or inadequately treated depression.AUSTEDO XR and AUSTEDO are also contraindicated in: patients with hepatic impairment; patients taking reserpine or within 20 days of discontinuing reserpine; patients taking monoamine oxidase inhibitors (MAOIs), or within 14 days of discontinuing MAOI therapy; and patients taking tetrabenazine or valbenazine.
Clinical Worsening and Adverse Events in Patients with Huntington’s Disease: AUSTEDO XR and AUSTEDOmay cause a worsening in mood, cognition, rigidity, and functional capacity. Prescribers should periodically re-evaluate the need for AUSTEDO XR or AUSTEDOin their patients by assessing the effect on chorea and possible adverse effects.
QTc Prolongation: AUSTEDO XR and AUSTEDO may prolong the QT interval, but the degree of QT prolongation is not clinically significant when AUSTEDO XR or AUSTEDO is administered within the recommended dosage range. AUSTEDO XR and AUSTEDO should be avoided in patients with congenital long QT syndrome and in patients with a history of cardiac arrhythmias.
Neuroleptic Malignant Syndrome (NMS), a potentially fatal symptom complex reported in association with drugs that reduce dopaminergic transmission, has been observed in patients receiving tetrabenazine. The risk may be increased by concomitant use of dopamine antagonists or antipsychotics. The management of NMS should include immediate discontinuation of AUSTEDO XR and AUSTEDO; intensive symptomatic treatment and medical monitoring; and treatment of any concomitant serious medical problems.
Akathisia, Agitation, and Restlessness: AUSTEDO XR and AUSTEDO may increase the risk of akathisia, agitation, and restlessness. The risk of akathisia may be increased by concomitant use of dopamine antagonists or antipsychotics. If a patient develops akathisia, the AUSTEDO XR or AUSTEDO dose should be reduced; some patients may require discontinuation of therapy.
Parkinsonism: AUSTEDO XR and AUSTEDOmay cause parkinsonism in patients with Huntington’s disease or tardive dyskinesia. Parkinsonism has also been observed with other VMAT2 inhibitors. The risk of parkinsonism may be increased by concomitant use of dopamine antagonists or antipsychotics. If a patient develops parkinsonism, the AUSTEDO XR or AUSTEDO dose should be reduced; some patients may require discontinuation of therapy.
Sedation and Somnolence: Sedation is a common dose-limiting adverse reaction of AUSTEDO XR and AUSTEDO. Patients should not perform activities requiring mental alertness, such as operating a motor vehicle or hazardous machinery, until they are on a maintenance dose of AUSTEDO XR or AUSTEDO and know how the drug affects them. Concomitant use of alcohol or other sedating drugs may have additive effects and worsen sedation and somnolence.
Hyperprolactinemia: Tetrabenazine elevates serum prolactin concentrations in humans. If there is a clinical suspicion of symptomatic hyperprolactinemia, appropriate laboratory testing should be done and consideration should be given to discontinuation of AUSTEDO XR and AUSTEDO.
Binding to Melanin-Containing Tissues: Deutetrabenazine or its metabolites bind to melanin-containing tissues and could accumulate in these tissues over time. Prescribers should be aware of the possibility of long-term ophthalmologic effects.
Common Adverse Reactions: The most common adverse reactions for AUSTEDO (>8% and greater than placebo) in a controlled clinical study in patients with Huntington’s disease were somnolence, diarrhea, dry mouth, and fatigue. The most common adverse reactions for AUSTEDO (4% and greater than placebo) in controlled clinical studies in patients with tardive dyskinesia were nasopharyngitis and insomnia. Adverse reactions with AUSTEDO XR extended-release tablets are expected to be similar to AUSTEDO tablets.
