What is Austedo?

Austedo (deutetrabenazine) is used to treat involuntary movement disorders in tardive dyskinesia (TD) and Huntington's disease (Huntington's chorea) to help reduce the severity of symptoms and improve quality of life.

Austedo works by changing the activity of natural chemical messengers (dopamine, serotonin, norepinephrine, and histamine) between nerve cells, which helps control involuntary muscle movements.  It does this by blocking a protein called VMAT2, which is responsible amount of chemical messengers in the nerve terminals.

Austedo drug class is VMAT2 inhibitors (vesicular monoamine transporter 2 inhibitor).

Austedo tablets are taken twice daily, and Austedo XR (extended-release tablets) are taken once daily.

What is Tardive dyskinesia (TD) and Huntington’s disease chorea

Tardive dyskinesia (TD) is a nervous system disorder that causes repetitive, uncontrolled muscle movements, usually in the face (chewing, lip smacking, frowning, tongue movement, blinking, or eye movement). Tardive dyskinesia can develop due to using certain medicines.

Huntington's disease chorea is sudden involuntary movements usually of the arms, legs, face, and tongue. It is an inherited disease that causes the progressive breakdown of nerve cells in the brain. Deutetrabenazine is not a cure for Huntington's disease and will not treat other symptoms of this condition.

How do Austedo tablets work?

Austedo mechanism of action (MOA) is as a vesicular monoamine transporter 2 (VMAT2) inhibitor, blocking VMAT2, which decreases the activity of neurotransmitters and helps to reduce unwanted body movements.

Body movement or motor function is controlled in the brain by nerve cells (neurons) that speak to each other by passing chemical messengers (neurotransmitters) from one nerve cell to another nerve cell.

In movement disorders such as Huntington’s disease and tardive dyskinesia, there can be a problem with this system, and by lowering the amount of chemical messengers between the nerve cells, you relieve the uncontrolled movements.

A protein called VMAT2 controls how much neurotransmitter is stored in the nerve cell and how much is absorbed.  The VMAT2 inhibitor blocks VMAT2, so there is a lower amount of neurotransmitter available, which reduces unwanted body movements.

Austedo FDA approval

Austedo FDA approval for treatment of chorea associated with Huntington’s disease was granted on April 3, 2017, based on positive results from deutetrabenazine clinical trials, the Phase III randomized, placebo-controlled study called First-HD. Total Maximal Chorea Scores were averaged over the maintenance period (week 9 to week 12).

Total Maximal Chorea Scores were improved by: 

• 4.4 units for deutetrabenazine patients 
• 1.9 units for placebo patients.

Austedo FDA approval for the treatment of tardive dyskinesia in adults was received on August 30, 2017, after positive results from deutetrabenazine clinical trials AIM-TD (NCT02291861) and ARM-TD, two Phase III randomized, double-blind, placebo-controlled, parallel-group studies. In the clinical trial, ARM-TD tardive dyskinesia severity was measured using the change in Abnormal Involuntary Movement Scale (AIMS) from baseline levels to levels at Week 12.

The AIMS total score was improved by: 

• 3.0 units for patients taking deutetrabenazine (statistically significant improvement)
• 1.6 units in the placebo group
• Treatment effect of -1.4 units. 

Warnings

QTc Prolongation 

This medicine may prolong the QT interval, but the degree of QT prolongation is not clinically significant when administered within the recommended dosage range.  Austedo tablets should be avoided in patients with congenital long QT syndrome and in patients with a history of cardiac arrhythmias associated with a prolonged QT interval. 

Certain circumstances may increase the risk of the occurrence of torsade de pointes and/or sudden death in association with the use of drugs that prolong the QTc interval, including: 

• slow heart rate (bradycardia),
• low potassium levels (hypokalemia), 
• low magnesium blood levels (hypomagnesemia), 
• having a congenital prolongation of the QT interval, and
• concomitant use of other drugs that prolong the QTc interval.

Depression and Suicide

Some people have thoughts about suicide while taking Austedo stay alert to changes in your mood, feelings, thoughts, or behaviors. Tell your doctor right away if you have any sudden changes in mood or behavior or thoughts about suicide.

You should not use this medicine if you have Huntington’s disease and you have untreated or uncontrolled depression, or if you have thoughts about suicide.

Other medicines

Do not use this medicine if you have taken reserpine (Serpalan, Renese-R) in the past 20 days, or if you have used an MAO inhibitor (isocarboxazid, linezolid, rasagiline, selegiline, and others) in the past 14 days. See the Interactions section for more interactions with this medicine.

Before taking this medicine

You should not use Austedo if you are allergic to deutetrabenazine, or if you have:

• untreated or uncontrolled depression;

• thoughts about suicide or hurting yourself;

• if you have recently taken tetrabenazine or valbenazine; or

• liver impairment.

Do not use this medicine if you have taken reserpine in the past 20 days, or if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, and tranylcypromine.

To make sure this medicine is safe for you, tell your doctor if you have ever had:

• depression, anxiety, nervousness, or agitation;

• mental illness or psychosis;

• suicidal thoughts or actions;

• breast cancer;

• a heart rhythm disorder;

• long QT syndrome (in you or a family member);

• an electrolyte imbalance (such as low blood levels of potassium or magnesium); or

• liver disease.

People with Huntington's disease may have a higher risk of depression and suicidal thoughts or behaviors. Taking this medicine may further increase this risk. However, the benefits of taking this medicine (improvement in daily living) may outweigh any suicidal risks.

Taking this medicine may cause symptoms similar to Parkinson's disease (resting tremor, stiff muscles, slow movements, difficulty maintaining balance, and walking). Ask your doctor about your risk.

Your doctor will need to check your progress on a regular basis. Your family or caregivers should also watch for sudden changes in your behavior.

Tell your doctor if you are pregnant or breastfeeding.

QT Prolongation This medicine may prolong the QT interval and should not be used with medicines that prolong the QTc interval. Talk to your healthcare provider about other medicines you take, or if you start taking new medicines.

Reserpine. Do not take this medicine if you are taking reserpine.  If your healthcare provider plans to switch you from taking reserpine to this medicine, you must wait at least 20 days after your last dose of reserpine before you start taking all forms of Austedo tablets and XR tablets.

Do not start this medicine if you stopped taking an MAOI (isocarboxazid, linezolid, rasagiline, selegiline, and others) in the last 14 days. Ask your healthcare provider or pharmacist if you are not sure.

Tetrabenazine. Austedo tablets and XR tablets are contraindicated in patients currently taking tetrabenazine. If your healthcare provider plans to switch you from tetrabenazine to Austedo tablets or XR tablets, take your first dose of Austedo tablets or XR tablets on the day after your last dose of tetrabenazine.

Valbenazine. This medicine is contraindicated in patients currently taking valbenazine.

Neuroleptic Drugs The risk of Parkinsonism, neuroleptic malignant syndrome (NMS), and being unable to remain still (akathisia) may be increased by using this medicine with dopamine antagonists or antipsychotics. Talk to your healthcare provider about other medicines you take, or if you start taking new medicines.

Alcohol or Other Sedating Drugs Using alcohol or other sedating drugs may have additive effects and make sedation and sleepiness worse.

Strong CYP2D6 inhibitors. A dose reduction in both forms of Austedo may be necessary when adding a strong CYP2D6 inhibitor in patients maintained on a stable dose of Austedo tablets or XR tablets. Using strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine, quinidine, bupropion) has been shown to increase both forms of Austedo's effectiveness. If you are using strong CYP2D6 inhibitors, the maximum recommended dose of Austedo tablets or XR tablets is 36 mg per day.
