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 new data from the 3-year open-label extension study of AUSTEDO® (deutetrabenazine) Tablets that studied patients with tardive dyskinesia (TD) will be presented at the 2021 American Psychiatric Association (APA) Virtual Annual Meeting, being held online from May 1-3.
The new data includes three abstracts that examine the long-term safety, quality of life (QoL) and patient-centered outcome measures of patients living with TD who were treated with AUSTEDO up to 145 weeks following two pivotal 12-week studies (ARM-TD and AIM-TD).
“TD is a serious movement disorder and we continue to evaluate AUSTEDO to determine its therapeutic potential following the pivotal clinical trials,” said Denisa Hurtukova, MD, VP, Head of North America Medical Affairs. “The data being presented at APA give healthcare providers valuable insights into safety and certain aspects of quality of life among TD patients, which could have an important impact on treatment considerations and ultimately the wellbeing of patients.”
In an analysis of the long-term safety of AUSTEDO, 337 patients with 723 patient-years of exposure were evaluated, all of whom had completed ARM-TD or AIM-TD. AUSTEDO was administered using a response-driven dosing regimen, titrating up to a maximum total daily dose of 48 mg/day based on dyskinesia control and tolerability. Safety measures included incidence of any adverse events (AEs), serious adverse events (SAEs) and AEs leading to withdrawal, dose reduction or dose suspension, as well as the most common AEs (≥4 percent). Since differences in incidence rates may be related to different durations of observation, exposure-adjusted incidence rates (EAIRs) were used to calculate AE frequencies. 269 (79.8 percent) patients reported ≥1 AE and AEs considered by the investigator to be treatment related were reported in 154 (45.7 percent) patients. Low EAIRs were reported for most AEs, including 1.22 for any AE, 0.09 for SAEs, 0.34 for treatment-related AEs, 0.06 for AEs leading to withdrawal, 0.05 for AEs leading to dose suspension, and 0.09 for AEs leading to dose reduction. The most common AEs (EAIRs) were anxiety (0.06), depression (0.05), somnolence (0.05), weight decreased (0.05) and urinary tract infection (0.05).

The OLE also investigated AUSTEDO in relation to patients’ QoL using the Modified Craniocervical Dystonia Questionnaire (mCDQ-24) score, a disease-specific QoL questionnaire adjusted to focus on the impact of TD. Patients’ QoL was evaluated based on the mean change +/- SE from baseline in the mCDQ-24 total score and the stigma, pain, activities of daily living (ADL), emotional and social subdomain scores through week 106. Of the 337 analyzed, changes in mean mCDQ-24 total scores from baseline were observed at week 6 (-3.2 +/- 0.68) and sustained through week 106 (-5.2 +/- 1.11). Treatment resulted in clinically meaningful improvements based on changes as measured by the mCDQ-24 total score and the stigma, pain, ADL, emotional and social subdomain scores.

Finally, the OLE also evaluated patient-centric outcomes, including the percentage of patients to achieve treatment success (defined as “much improved” or “very improved”) on the Patient Global Impression of Change (PGIC), change from baseline in the patient-reported modified mCDQ-24 score and changes from baseline in the Abnormal Involuntary Movement Scale (AIMS) items 8, 9, 10, which are clinician-rated global judgments of the overall severity of abnormal movements, the incapacitation due to abnormal movements, and the patient’s awareness of abnormal movements, respectively. The analysis found more than half of the patients achieved PGIC treatment success at week 6, and the proportion increased over time from 54 percent at weeks 6 and 15, to 61 percent at week 54, 64 percent at week 106 and 63 percent at week 145. According to the mCDQ-24 score, patients demonstrated improvement in QoL at week 6 (mean change +/- SE from baseline: -3.2 +/- 0.68) that continued throughout the study (week 15, -5.0 +/- 0.70; week 54, -5.0 +/- 0.89; week 106, -5.2 +/- 1.11). Patients also experienced improvements from baseline in AIMS items 8, 9 and 10, which were sustained through week 145 (mean change +/- SE: -1.3 +/- 0.07 for item 8; -1.3 +/- 0.08 for item 9, and -1.3 +/- 0.09 for item 10).

AUSTEDO® Indications and Usage
AUSTEDO® is indicated for the treatment of chorea associated with Huntington’s disease and for the treatment of tardive dyskinesia in adults.
Important Safety Information About AUSTEDO®
Depression and Suicidality in Patients with Huntington’s Disease: 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® is contraindicated in patients who are suicidal, and in patients with untreated or inadequately treated depression.
Contraindications: AUSTEDO® is contraindicated in patients with Huntington’s disease who are suicidal, or have untreated or inadequately treated depression. AUSTEDO® is 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 (Xenazine®) or valbenazine (Ingrezza®).
Clinical Worsening and Adverse Events in Patients with Huntington’s Disease: AUSTEDO® may cause a worsening in mood, cognition, rigidity, and functional capacity. Prescribers should periodically re-evaluate the need for AUSTEDO® in their patients by assessing the effect on chorea and possible adverse effects.
QTc Prolongation: AUSTEDO may prolong the QT interval, but the degree of QT prolongation is not clinically significant when AUSTEDO is administered within the recommended dosage range. 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®; intensive symptomatic treatment and medical monitoring; and treatment of any concomitant serious medical problems.
Akathisia, Agitation, and Restlessness: 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® dose should be reduced; some patients may require discontinuation of therapy.
Parkinsonism: AUSTEDO® may 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® dose should be reduced; some patients may require discontinuation of therapy.
Sedation and Somnolence: Sedation is a common dose-limiting adverse reaction of 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® 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®.
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.
