Ethical Approaches to Limiting Overall Costs for Glucagon-Like Peptide-1 Receptor Agonists for Weight Management

This article evaluates seven strategies for managing the high costs of GLP-1 receptor agonists (GLP-1RAs) like semaglutide and tirzepatide for weight management: complete exclusion of coverage, annual cost increase caps, lifetime cost caps, tiered access, formulary reevaluation, subscription payment models, and patent reform. The authors assess each strategy against three ethical objectives: benefiting people and preventing harm, showing equal moral concern, and mitigating disadvantage. Complete coverage exclusions, arbitrary reimbursement caps, and lifetime limits are deemed unethical as they fail to meet these objectives. Tiering access based on relative benefit is considered justifiable, though current implementation often unfairly favors diabetes over obesity treatment. The authors recommend formulary reevaluation as the most ethical approach for smaller health plans, allowing them to prioritize more cost-effective treatments. For larger payers with market power and for governments, subscription payment models and patent reforms are potentially ethical solutions if implemented sustainably. The authors conclude that health plans should avoid ad hoc restrictions on GLP-1RAs in favor of comprehensive policy reforms that ensure sustainable access to these and future breakthrough treatments.
