The single biggest commercial lever is ARIA fear management at infusion 7+: patients who hit a brain-swelling episode report feeling "so alone" and are at highest abandonment risk, yet most resolve with steroids and can re-start.
- Kisunla's finite-duration framing (stop when plaque clears, typically 6-18 months) is its sharpest patient-facing differentiator versus Leqembi's indefinite dosing, and patients are actively researching this tradeoff in forum discussions.
- ARIA-E is the dominant adherence-threat: patients who experience brain swelling mid-course feel isolated and fear permanent discontinuation, creating a critical peer-support gap that the brand can close.
- Insurance prior-authorization friction and out-of-pocket cost uncertainty (Medicare copays estimated near $4,000/year; private insurers frequently deny) are the leading pre-treatment abandonment drivers, not safety concerns.
- Monthly infusion convenience and early-intervention urgency are the two strongest pull-through drivers; patients who start early and tolerate initial infusions tend to sustain treatment with optimism about functional preservation.
