Summary
The provided evaluation largely aligns with the label for depression/suicidality in Huntington’s disease (5.1, 4, 17), but the overall response includes multiple additional general label/efficacy/PD claims that were not provided in the label excerpts supplied for evaluation, leaving those portions unsupported by the supplied prescribing information.

Accurate Statements
In patients with Huntington’s disease, AUSTEDO/AUSTEDO XR increases the risk of depression and suicidality.
Supported by Sections 5.1 (increased suicidality risk; increased baseline risk for depression/suicidality) and 17 (counseling). Depression and suicidal ideation rates are provided in 5.1.
Contraindicated in patients with Huntington’s disease who are suicidal, or have untreated or inadequately treated depression.
Supported by Section 4 contraindications referencing Warnings and Precautions (5.1).
Suicidal ideation was reported by 2% of patients treated with AUSTEDO versus no patients on placebo; depression reported by 4% of patients treated with AUSTEDO.
Supported by Section 5.1 trial results excerpt provided.
Unsupported Statements
Austedo is used to treat tardive dyskinesia (TD).
The supplied prescribing information excerpts for evaluation do not include the approved indications section; no label text for TD was provided.
Austedo is used to treat chorea associated with Huntington's disease (HD).
The supplied prescribing information excerpts for evaluation do not include the approved indications section; no label text for this indication was provided.
Austedo is indicated for the treatment of chorea, a symptom characterized by involuntary, jerky movements.
No definition/indication statement from the supplied excerpts was provided.
Teva Pharmaceuticals received FDA approval for Austedo for the treatment of chorea associated with Huntington's disease in 2017.
No FDA approval/approval year or sponsor-specific approval timeline is present in the supplied excerpts.
Teva Pharmaceuticals received approval for Austedo for the treatment of tardive dyskinesia in 2017.
No FDA approval/approval year or sponsor-specific approval timeline is present in the supplied excerpts.
Austedo is a reversible inhibitor of monoamine oxidase B (MAO-B).
Mechanism statement not supported by the supplied excerpts (only a different section excerpt set was provided, focusing on depression/suicidality risk).
Austedo is a depletor of vesicular monoamine transporter 2 (VMAT2).
Mechanism statement not supported by the supplied excerpts; the provided drug/active ingredient note says VMAT2 inhibitor, but no label excerpt supporting this mechanistic phrasing was supplied.
Austedo helps manage involuntary movements characteristic of tardive dyskinesia.
The supplied excerpts do not include efficacy/indication language for tardive dyskinesia.
Austedo helps manage Huntington's disease chorea by affecting monoamine neurotransmitters in the brain.
The supplied excerpts do not include efficacy language describing the mechanism as affecting monoamine neurotransmitters.
Contradictions
Important Omissions
For the subset of depression/suicidality risk, the evaluation does not explicitly reflect/quote the label’s instruction to observe patients for new or worsening depression or suicidality and to consider discontinuing if depression/suicidality does not resolve.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
Low
The core evaluated safety claim (depression/suicidality risk in Huntington’s disease) is supported by the provided label excerpts. However, additional unsupported general claims about indications/mechanism were included, and some management instructions from 5.1 were not explicitly represented.

Recommendation
Mostly Aligned
Primary Issue
Multiple claims (indications, approval year, and mechanism) are not supported by the prescribing information excerpts provided for evaluation.
Suggested Improvement
Limit the response to the label text provided for evaluation (primarily Sections 4, 5.1, and 17) and explicitly include key 5.1 management/monitoring instructions (observe patients; consider discontinuation if depression/suicidality does not resolve) when discussing the risk.
