 MA plans' near-universal prior authorization creates administrative friction that may worsen the already-poor adherence rates for GLP-1s. PA requirements ensure only T2D-diagnosed patients can access, effectively blocking obesity-only coverage despite FDA approval. This access restriction compounds the chronic-use economics challenge by adding administrative barriers on top of existing adherence problems.

+MASH/NASH is projected to become the leading cause of liver transplantation. GLP-1s now demonstrate efficacy across three major organ systems (cardiovascular, renal, hepatic), which strengthens the multi-indication economic case for chronic use. The 62.9% MASH resolution rate suggests GLP-1s could prevent progression to late-stage liver disease and transplantation, though the Value in Health Medicare study showed only $28M MASH savings—surprisingly small given clinical magnitude, likely because MASH progression to transplant takes decades and falls outside typical budget scoring windows.

 SELECT trial exploratory analysis (N=17,604, median 41.8 months) shows semaglutide reduces ALL-CAUSE hospitalizations by 10% (18.3 vs 20.4 per 100 patient-years, P<.001) and total hospital days by 11% (157.2 vs 176.2 days per 100 patient-years, P=.01). Critically, benefits extended beyond cardiovascular causes to total hospitalization burden, suggesting systemic effects across multiple organ systems.

+Phase 3 trial shows semaglutide 2.4mg achieves 62.9% resolution of steatohepatitis without worsening fibrosis vs 34.3% placebo. Meta-analysis confirms GLP-1 RAs significantly increase histologic resolution of MASH, decrease liver fat deposition, improve hepatocellular ballooning, and reduce lobular inflammation. Some hepatoprotective benefits appear at least partly independent of weight loss, suggesting direct liver effects beyond metabolic improvement. This adds hepatic protection as a third major organ system (alongside cardiovascular and renal) where GLP-1s demonstrate protective effects.

 PRIMARY CONNECTION: [[GLP-1 receptor agonists are the largest therapeutic category launch in pharmaceutical history but their chronic use model makes the net cost impact inflationary through 2035]]
 WHY ARCHIVED: Third organ-protection pathway (after CV and kidney) strengthens the case that GLP-1s should be evaluated as multi-organ protective agents, not just weight loss drugs
 EXTRACTION HINT: The multi-organ protection thesis may justify reframing the existing GLP-1 claim from a weight-loss-economics frame to a metabolic-disease-prevention frame
