Pharmaceutical companies and payers typically have several goals when considering an outcomes-based contract. For pharmaceutical companies, goals may include improving a drug’s position on the preferred drug list of a health plan, accelerating the availability of new treatments on a formulary, reaching an agreement on a reimbursement framework when some longer-term benefits are still unproven, and getting drugs to the market more quickly. For payers, costs are a primary concern, particularly for high-cost new therapies that are unproven in the real world. Payers are also interested in improving allocation of resources towards their members most likely to receive benefit.
