The BALANCE Model directly addresses the chronic use inflation problem by requiring lifestyle interventions alongside medication. If lifestyle supports can sustain metabolic benefits after medication discontinuation, the model could demonstrate a pathway to positive net cost impact. The 6-year test window (through 2031) will provide empirical data on whether combined intervention changes the chronic use economics.
### Additional Evidence (challenge)
*Source: [[2026-01-13-aon-glp1-employer-cost-savings-cancer-reduction]] | Added: 2026-03-16*
Aon's 192K patient analysis shows medical cost growth drops to 2% after 12 months for GLP-1 users vs. 6% for non-users, with diabetes patients showing 6-9 percentage point lower cost growth at 30 months. This challenges the 'inflationary through 2035' thesis for long-term risk-bearers—the data suggests net savings emerge within 18-30 months for adherent users in capitated systems, though short-term payers and non-adherent populations still face inflation.

FLOW trial demonstrated 29% reduction in cardiovascular death (HR 0.71, 95% CI 0.56-0.89) and 18% lower risk of major cardiovascular events in a kidney-focused trial. The cardiovascular benefits emerged as secondary endpoints in a study designed for kidney outcomes, supporting the multi-organ protection thesis. Separate analysis in Nature Medicine showed additive benefits when combined with SGLT2 inhibitors.

Aon's 192K patient analysis found adherent GLP-1 users (80%+) had 47% fewer MACE hospitalizations in women and 26% in men, with the sex differential suggesting larger cardiovascular benefits for women. This adds to the multi-organ protection thesis by showing substantial cardiovascular risk reduction in real-world commercial populations, not just clinical trials.

No data yet on whether payment model affects persistence—does being in an MA plan with care coordination improve adherence vs. fee-for-service? This is directly relevant to value-based care design.
### Additional Evidence (extend)
*Source: [[2026-01-13-aon-glp1-employer-cost-savings-cancer-reduction]] | Added: 2026-03-16*
Aon data shows adherence is the binding variable for GLP-1 effectiveness—the 80%+ adherent cohort shows dramatically stronger effects across all outcomes (9 percentage point lower cost growth vs. 6 points for all diabetes users; 7 points vs. 3 for weight loss users). This confirms that low persistence rates directly undermine the cost-effectiveness case because benefits scale non-linearly with adherence.

The source does not provide granular income-stratified discontinuation rates, so the magnitude of the effect is unclear. It's possible income is a proxy for other factors (health literacy, access to care coordination, baseline health status) rather than affordability per se.

*Source: [[2026-01-13-aon-glp1-employer-cost-savings-cancer-reduction]] | Added: 2026-03-16*
Aon's commercial claims data (employer-sponsored insurance) shows strong adherence effects, but the sample is biased toward employed, insured populations. The finding that benefits require 80%+ adherence indirectly supports the affordability thesis—populations with coverage gaps or cost-sharing barriers cannot achieve the adherence levels needed for cost-effectiveness.

## Key Facts
- Aon analyzed commercial health claims data from 192,000+ GLP-1 users in U.S. employer-sponsored plans
- First 12 months on Wegovy/Zepbound: medical costs rise 23% vs. 10% for non-users
- After 12 months: medical costs grow 2% vs. 6% for non-users
- For diabetes indication: medical cost growth 6 percentage points lower at 30 months; 9 points lower with 80%+ adherence
- For weight loss indication: cost growth 3 points lower at 18 months; 7 points lower with consistent use
- Female GLP-1 users: ~50% lower ovarian cancer incidence, 14% lower breast cancer incidence
- Adherent users (80%+): 47% fewer MACE hospitalizations in women, 26% in men
