The agent successfully pieced together a comprehensive explanation of Repatha by combining homepage content with one pricing page fetch; however, the site's navigation structure was broken (multiple 404s on intuitive URLs), forcing the agent to retrieve competitive comparison data from third-party sources rather than site-native content.

• ›The homepage (step [1]) was the primary source of substance, delivering core positioning, patient segments, and support programs. Most intuitive secondary URLs (about-repatha, cost-and-coverage, patient-resources) returned 404s, indicating broken site architecture.
• ›The working pricing page (step [9], /repatha-cost) provided tiered insurance breakdowns and co-pay specifics that the homepage had only hinted at, and this single resource became crucial for the pricing answer.
• ›The agent had to rely on external third-party sources (steps [8], [10]) to answer the competitive differentiation question; repatha.com does not publish direct comparisons to Praluent or other PCSK9 inhibitors, despite this being a core evaluative need.
• ›The mechanism-of-action page (step [4], /how-repatha-works) effectively explained PCSK9 inhibition versus statins, but the URL was reached only because the agent inferred it from homepage language — the site did not surface a navigation path to it.
• ›The agent correctly identified that repatha.com is primarily a patient support and financial assistance resource rather than a comprehensive educational or comparison site, noting specific clinical details (LDL thresholds, dosing frequency) were absent or buried.
