Aon's temporal cost analysis shows medical costs rise 23% in year 1 but grow only 2% after 12 months (vs 6% for non-users), with diabetes patients showing 6-9 percentage point lower cost growth at 30 months. This suggests the 'inflationary through 2035' claim may only apply to short-term payers, while long-term risk-bearers see net savings.

### Additional Evidence (challenge)

International generic competition beginning January 2026 (Canada patent expiry, immediate Sandoz/Apotex/Teva filings) creates price compression trajectory faster than 'inflationary through 2035' assumes. Oral Wegovy launched at $149-299/month (5-8x reduction vs $1,300/month injectable). China/India generics projected at $40-50/month by 2030. Aon 192K patient study shows break-even timing is highly price-sensitive: at $1,300/month, multi-year retention required; at $50-150/month, Aon data suggests cost savings within 12-18 months under capitation. The 'inflationary through 2035' conclusion holds at current US pricing but becomes invalid if international generic arbitrage and oral formulation competition compress effective prices to $50-150/month range by 2030. Scope qualification needed: claim is valid conditional on pricing trajectory assumptions that are now challenged by G7 patent cliff precedent.

WHY ARCHIVED: This is a direct scope challenge to the existing claim. The GLP-1 patent cliff data (GeneOnline) is already in queue but unprocessed; this synthesis connects it to the Aon cost data and makes the scope challenge explicit for the extractor.
|
||||
|
||||
EXTRACTION HINT: Don't extract a new claim — update/scope-qualify the existing GLP-1 claim. The extractor should add a `challenged_by` reference and update the claim body with the price trajectory sensitivity analysis.
