Not Aligned
Primary Issue
The content does not evaluate or reflect FDA-approved prescribing information claims; it contains multiple statements that are not supported by the provided label excerpts.
Suggested Improvement
Provide the specific AI-generated prescribing/safety claim(s) to audit against the Vyvgart FDA label (e.g., include the exact statement and the relevant label section/excerpt), rather than patent/market-entry commentary.
