There are different models for determining the price of medicines, but value-based pricing that considers the outcomes a treatment provides relative to its cost is likely the most appropriate approach. However, current pricing and reimbursement systems face challenges in applying value-based pricing due to uncertainties in data, combination therapies, multi-indication drugs, and ensuring treatments are both cost-effective and affordable for healthcare systems. Fair pricing requires balancing incentives for pharmaceutical innovation with improving access and affordability for patients.
