'As part of Teva's commitment to advancing treatment innovation for schizophrenia patients, this research provides clinical insights into how healthcare providers may switch appropriate patients to UZEDY, a subcutaneous risperidone LAI option with flexible dosing,' said
Presented data include population pharmacokinetic (PopPK) modeling to investigate dosing conversion strategies for switching patients to a once-monthly or once every two-months subcutaneous dose of UZEDY from a biweekly intramuscular LAI formulation of risperidone microspheres (R064766). The analysis aims to address the knowledge gap as limited clinical data currently exist on optimal strategies for switching between the various available LAI treatment options, which have differing pharmacokinetic (PK) properties.
In the PopPK analysis, patient model simulations showed that switching to UZEDY at 4-6 weeks after the last dose of R064766 provided comparable PK exposures by the second dose. Specifically, switching patients to UZEDY 5 weeks after the last dose of R064766 achieved PK exposures similar to those achieved with R064766 at a steady state. The optimal switching strategy should be determined by clinicians on an individual basis, considering factors such as patient preference, scheduling convenience, and potential tolerability issues or risk of symptom breakthrough.
Additional key data being presented at the SIRS Annual Meeting include: New data from RISE (Risperidone Subcutaneous Extended-Release Study), the Phase 3 pivotal trial that supported the FDA approval of UZEDY. An analysis estimated the number needed to treat (NNT) and the number needed to harm (NNH), clinically relevant measures that help provide healthcare providers with an understanding of the benefits and risks of UZEDY and inform clinical decision-making.
Qualitative data from two ADVANCE (Attitudes Driving Regional Differences in LAI Antipsychotic Utilization for Schizophrenia Among Healthcare Professionals, Patients, and Caregivers) surveys: In the healthcare provider survey, ten psychiatrists (spending an average of 45% of their time at hospital-based outpatient clinics) and seven psychiatric nurses (averaging 47% of time at community mental health centers) were interviewed. Findings suggest that regional differences in LAI utilization rates are likely influenced by a combination of factors, including systemic, HCP, and patient factors.
In the patient survey, approximately 20 patients and 19 caregivers completed a 60-minute interview regarding the use of LAIs in schizophrenia. Unfavorable early experiences, especially in the inpatient setting, can negatively impact patients' perception of and willingness to accept LAIs. The survey findings offer further key insights into addressing global adherence and inconsistent utilization challenges with LAIs.
About Schizophrenia
Schizophrenia is a chronic, progressive and severely debilitating mental disorder that affects how one thinks, feels and acts.1 Patients experience an array of symptoms, which may include delusions, hallucinations, disorganized speech or behavior and impaired cognitive ability.1,2,3 Approximately 1% of the world's population will develop schizophrenia in their lifetime, and 3.5 million people in the
About UZEDY
UZEDY (risperidone) extended-release injectable suspension, for subcutaneous use, is indicated for the treatment of schizophrenia in adults. In clinical trials, UZEDY significantly reduced the risk of schizophrenia relapse.7,8 UZEDY administers risperidone through copolymer technology under license from

AUSTEDO XR and AUSTEDO are the first vesicular monoamine transporter 2 (VMAT2) inhibitors approved by the
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.
