DEUTETRABENAZINE TAB
Clinical Criteria Summary
Document 276
Exclusion Criteria
- Actively suicidal or has untreated or inadequately treated depression
- Congenital long QT interval, or a QTc >450 ms for men or QTc >470 ms for women
- History of cardiac arrhythmias (ventricular), cardiac conduction system disease (LBBB or RBBB), or cardiac device (can be considered candidates with cardiology evaluation)
- Concurrent use of a monoamine oxidase inhibitor (MAOI) or within 14 days of discontinuing therapy with an MAOI
- Current or use of reserpine within the past 20 days
- Concurrent use of another VMAT2 inhibitor (i.e., tetrabenazine, valbenazine)
- History of neuroleptic malignant syndrome (NMS)
- Current clinically significant hyperprolactinemia
- Pregnant or lactating
- Hepatic impairment
Inclusion Criteria: Treatment of Huntington Disease
- Initial prescriber is a resident, fellow, or other trainee: an attending psychiatrist or neurologist has verified the diagnosis and need for deutetrabenazine
- Diagnosis of Huntington disease documented in the medical record
- Chorea is disabling or painful and interferes with functional status (including self-care and ambulation), quality of life, or creates a social stigma sufficient to cause social isolation or embarrassment
- Prescriber has documented specific movement(s) (e.g., facial, oral, extremity, or trunk) in the medical record along with how the chorea is affecting function, quality of life, or socialization
Inclusion Criteria: Treatment of Dystonia
- Initial prescriber is a resident, fellow, or other trainee: an attending psychiatrist or neurologist has verified the diagnosis and need for deutetrabenazine
- No response or intolerant to alternative agents (local botulinum toxin injections, anticholinergics, or benzodiazepines)
Inclusion Criteria: Treatment of Tardive Dyskinesia
- Diagnosis of tardive dyskinesia (TD) secondary to a dopaminergic blocking agent (e.g., antipsychotic or metoclopramide)
- TD interferes with functional status (including self-care and ambulation), quality of life, or creates a social stigma sufficient to cause social isolation or embarrassment
- Prescriber has documented specific movement(s) (e.g., facial, oral, extremity, or trunk) in the medical record along with how TD is affecting function, quality of life, or socialization
- Recent Abnormal Involuntary Movement Scale (AIMS) score is recorded in the medical record
- ECG performed to confirm a QTc <450 ms for men or QTc <470 ms for women
- Initial prescriber is a resident, fellow, or other trainee: an attending psychiatrist or neurologist has verified the diagnosis and need for deutetrabenazine

Indications
- Management of chorea associated with Huntington disease (HD)
- Management of tardive dyskinesia (TD)
Dosage & Administration
- Dosage form: Oral tablets (6 mg, 9 mg, 12 mg); non-formulary status
- Administer with food; swallow tablets whole (do not crush, chew, or break)
- HD dosing: 6 mg once daily; may increase dose weekly based on response and tolerability in increments of 6 mg/day. If total daily dose is ≥12 mg, administer in two divided doses. Maximum recommended dose: 48 mg/day.
- TD dosing: 6 mg twice daily; may increase dose weekly based on response and tolerability in increments of 6 mg/day. If total daily dose is ≥12 mg, administer in two divided doses. Maximum recommended dose: 48 mg/day.
Contraindications
- Suicidal/untreated depression
- Hepatic impairment
- Taking reserpine
- Taking MAOI (monoamine oxidase inhibitor)
- Taking another VMAT-2 inhibitor
Warnings & Precautions
- Box warning for depression and suicidality
- Neuroleptic malignant syndrome
- Akathisia, restlessness, agitation
- Parkinsonism
- Sedation and somnolence
- QTc prolongation
Adverse Reactions
- HD: Somnolence, diarrhea, dry mouth, fatigue, insomnia
- TD: Insomnia, nasopharyngitis, depression, akathisia
Drug Interactions
- Strong CYP2D6 inhibitors
- Reserpine
- MAOIs
- Alcohol/Sedating drugs
- Drugs causing QTc prolongation
- Neuroleptic drugs
- Concomitant VMAT-2 inhibitors
Efficacy
- HD: Demonstrated reduction in Total Chorea Score compared to placebo (p<0.0001) in a 12-week randomized, double-blind, placebo-controlled study.
- TD: Demonstrated reduction in Abnormal Involuntary Movement Scale (AIMS) scores compared to placebo at week 12 in the AIM-TD and ARM-TD trials.
Place in Therapy & Utilization
- VMAT-2 inhibitor utilized for management of HD chorea and TD.
- Indirect evidence suggests better tolerability compared to tetrabenazine, though VA ADERS data does not fully support this finding.
- Sequencing of VMAT-2 inhibitors is not warranted based on current evidence and utilization data.
