Teva to Present New Data at The MDS Virtual Congress 2020 and Psych Congress 2020 Virtual Experience Evaluating Long-Term Treatment with AUSTEDO® (deutetrabenazine) Tablets

Teva Neuroscience, Inc., an affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) will present new study data on AUSTEDO at the International Parkinson and Movement Disorder Society annual congress (MDS Virtual Congress 2020) and Psych Congress 2020 Virtual Experience evaluating the long-term efficacy and safety of AUSTEDO in patients with tardive dyskinesia (TD), and the safety and tolerability of AUSTEDO during periods of titration and maintenance in patients with TD.

"Tardive dyskinesia causes involuntarily, uncontrollable movements, that can have a significant impact on functioning and emotional well-being of those living with the condition," said Daniel McBryan, M.D., Senior Vice President, Head of Global Medical Affairs and Pharmacovigilance at Teva. "The data being presented this year deepen our understanding of the risk-benefit profile of AUSTEDO over the long-term, in patients most severely impacted by TD, and provides context around the dosing schedule."

Three Year Efficacy and Safety of AUSTEDO for Treatment of TD

The open-label extension of the pivotal ARM-TD and AIM-TD studies evaluated the long-term efficacy and safety of AUSTEDO for the treatment of TD. Treatment was titrated up to a maximum daily dose of 48 mg based on control of movements and medication tolerability and results were evaluated measuring change from baseline in Abnormal Involuntary Movement Scale (AIMS) scores and Clinical Global Impression of Change (CGIC). The following outcomes were recorded:

• At Week 54 (n=249; total daily dose [mean±SE]: 38.7±0.66 mg), mean change from baseline in AIMS score was -4.8±0.28, and physician assessments reported 66% of patients met the "much improved" or "very much improved" scores on the CGIC.
• At Week 106 (n=194; total daily dose: 39.3±0.75 mg), mean change from baseline in AIMS score was -5.4±0.33, and physician assessments reported 65% of patients met the "much improved" or "very much improved" scores on the CGIC.
• At Week 145 (n=160; total daily dose: 39.4±0.83 mg), mean change from baseline in AIMS score was -6.6±0.37, and physician assessments reported 73% of patients met the "much improved" or "very much improved" scores on the CGIC.

No new safety signals were identified in this population that were inconsistent with the known safety profile of AUSTEDO.

Long-Term Efficacy and Safety of AUSTEDO In Patients Severely Impacted by TD

A post hoc analysis of the open-label extension portion of the pivotal ARM-TD and AIM-TD studies evaluated the efficacy of AUSTEDO in reducing TD in the most severely impacted patients. Using the upper quartile of baseline AIMS scores from the open-label extension, two subgroups were defined as having scores >14 or ?14. At all-time points from Week two to Week 145, change from baseline in AIMS score was greater in those with baseline AIMS score >14 versus ?14 (mean ±SE at Wk 145: -10.9±0.8, -5.1±0.3). Percent change from baseline in patients with AIMS score >14 reached -59.4%±3.6% versus -55.2%±3.1% for patients with AIMS score ?14 at Week 145. The percent of patients with ?50% AIMS reduction at each visit was 71% in patients with baseline AIMS score >14 versus 64% in patients with AIMS score ?14 at Week 145.

No new safety signals were identified in this population that were inconsistent with the known safety profile of AUSTEDO.

Safety and Tolerability of AUSTEDO During Titration and Maintenance

The study evaluated data from the ARM-TD and AIM-TD studies and the open-label extension through week 15 to examine the safety and tolerability of AUSTEDO during titration and maintenance phases of therapy.

For flexible-dose AUSTEDO, the only common AE during titration was somnolence (11.2%); there were no common AEs during maintenance. Rates of specific AEs in titration and maintenance were (ranges for all groups in both periods: parkinsonism, 0?1.4%; suicidal ideation, 0?2.7%; akathisia, 0?1.8%; restlessness, 0?1.4%).

All abstracts presented at MDS Virtual Congress 2020 will be published in the Movement Disorders journal e-supplement and displayed as an e-poster in the 2020 Virtual Poster. Abstracts at the Psych Congress 2020 Virtual Experience will be available online in the virtual exhibit hall.

About AUSTEDO^® (deutetrabenazine)

AUSTEDO^® is a vesicular monoamine transporter 2 (VMAT2) inhibitor approved by the U.S. Food and Drug Administration for the treatment of tardive dyskinesia in adults and for the treatment of chorea associated with Huntington's disease. Safety and effectiveness in pediatric patients have not been established.

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: Tetrabenazine, a closely related VMAT2 inhibitor, causes an increase in the corrected QT (QTc) interval. A clinically relevant QT prolongation may occur in some patients treated with AUSTEDO^® who are CYP2D6 poor metabolizers or are co-administered a strong CYP2D6 inhibitor. Dose reduction may be necessary. The use of AUSTEDO^® in combination with other drugs known to prolong QTc may result in clinically significant QT prolongations. For patients requiring AUSTEDO^® doses greater than 24 mg per day who are using AUSTEDO^® with other drugs known to prolong QTc, assess the QTc interval before and after increasing the dose of AUSTEDO^® or the other drugs. 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.

CYP2D6 Metabolism: In patients who are poor CYP2D6 metabolizers or are taking strong CYP2D6 inhibitors, the total daily dosage of AUSTEDO^® should not exceed 36 mg (maximum single dose of 18 mg).

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.
