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 patient- and physician-reported interim results from the Phase 4 IMPACT-TD Registry study, reinforcing that TD has a wide-reaching, multidimensional impact on patients’ quality of life. These interim findings from the IMPACT-TD study were presented at the 2024 Psych Congress Elevate Annual Meeting, taking place from May 30 – June 2 in Las Vegas, Nevada.
“TD can be a devastating setback for those who have achieved mental stability with their psychiatric medication,” said Eric Hughes, MD, PhD, Executive Vice President of Global R&D and Chief Medical Officer at Teva. “These interim findings from IMPACT-TD Registry, the largest study of its kind, reveal the profound effect that TD can have on a patient’s life, beyond the clinic. Understanding the full impact of TD and how approved treatment options for TD, like once-daily AUSTEDO XR and twice-daily AUSTEDO, can help treat the condition is critical to improving outcomes for patients and is a driving force in our unwavering commitment to developing meaningful solutions for them.”
The two-part IMPACT-TD study is a 3-year longitudinal observational study evaluating how TD progresses over time and impacts a patient’s quality of life (Part A), as well as outcomes related to treatment with once-daily AUSTEDO XR and twice-daily AUSTEDO (Part B).
Clinician-reported TD severity and impact is assessed using the IMPACT-TD scale, the AIMS (Abnormal Involuntary Movement Scale) and the CGIS-TD (Clinical Global Impression of Severity of TD) scale. The interim analysis includes 286 patients with varying levels of TD severity and highlights, for the first time, that clinicians reported that TD has a multidimensional impact, even on patients with mild TD severity. Clinician-reported IMPACT-TD findings show:
- 98% of patients experience the impact of TD in some aspect of their quality of life
- 83% of patients experience moderate to severe impact across various quality of life domains, including social (59%), psychological/psychiatric (70%), physical (53%) and vocational/educational/recreational (57%)
- 54% and 61% of patients with “very mild” and “mild” TD severity based on CGIS-TD, respectively, experience moderate to severe impact on their quality of life
Patient-reported TD impact is assessed using the novel IMPACT-TD PRO (IMPACT-TD Patient-Reported Outcome) scale. Patient-reported findings, as assessed with the IMPACT-TD PRO, show:
- 59% and 57% of patients reported that TD caused embarrassment in social situations and impacted their ability to enjoy the things they do for fun, respectively
- 43% of patients reported that TD impacts their sleep
- 38-42% of patients reported experiencing the physical impact of TD, including on their ability to hold things, do chores and exercise
“These data provide a clearer understanding as to how the abnormal movements of TD significantly impact the daily functioning of patients that cannot be gleaned from looking solely at the severity of the movements,” said Richard Jackson, MD, an Assistant Clinical Adjunct Professor in the University of Michigan School of Medicine’s Department of Psychiatry and the study’s lead investigator. “TD can impact all domains of daily functioning including social, psychological, physical, occupational and recreational aspects of daily living even when the abnormal movements appear to be mild. This emphasizes the need for all clinicians to assess not only the severity of a patient’s TD movements but the impact those movements can have on all aspects of life. Continuing to understand the multifaceted impact of TD and finding ways to alleviate these burdens is crucial to supporting patients on their TD journey.”
Also presented at Psych Congress Elevate 2024 were data supporting:
- The development and internal validation of the IMPACT-TD PRO scale, suggesting that the questionnaire can effectively and reliably characterize the multidimensional impact of TD in adult patients.
- Final results from the TD cohort of the Phase 4 START study, which investigated real-world treatment outcomes for patients starting AUSTEDO with the 4-week Titration Kit. These full START results show that the titration kit successfully helped patients with TD find individualized therapeutic AUSTEDO doses with effectiveness similar to that observed in the pivotal clinical trials, with high adherence and patient satisfaction rates.
- Findings from a retrospective study comparing healthcare resource utilization (HCRU) in patients with TD treated with benztropine versus non-treated patients with TD suggest that benztropine can result in potential harm and increased cost for the patient if used off-label for the treatment of TD.
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.1,2,3
About AUSTEDO XR Extended-Release Tablets and AUSTEDO Tablets
AUSTEDO XR and AUSTEDO are the first vesicular monoamine transporter 2 (VMAT2) inhibitors 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. Safety and effectiveness in pediatric patients have not been established. AUSTEDO XR is the once-daily formulation of AUSTEDO.
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 AUSTEDO may cause a worsening in mood, cognition, rigidity, and functional capacity. Prescribers should periodically re-evaluate the need for AUSTEDO XR or AUSTEDO in 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 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 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.
