Abstract 1536O
Background
In the US, single drug prices do not reflect the value of supplemental indications. Indication-specific and weighted-average pricing were suggested for drugs with multiple indications. Under indication-specific pricing, a distinct price is assigned to the differential value a drug offers in each indication. Under weighted-average pricing, a single drug price is calculated reflecting the value and/or volume of each indication. This study estimates price reductions and cost savings for cancer drugs under indication-specific pricing and weighted-average pricing.
Methods
FDA-approved cancer drugs and indication (2003-2022). Data on each indication were collected from FDA labels, the Global Burden of Disease study, clinicaltrials.gov, and Medicare and Medicaid. A multivariate regression analysis, informed by original indications’ innovativeness, disease, and trial characteristics, was used to predict indication-specific prices for supplemental indications. These indication-specific prices were combined with each indication’s prevalence data to estimate weighted-average prices and potential cost savings under each policy.
Results
The FDA approved 162 anti-cancer drugs with 373 indications between 2003-2022. Of these, price data were available for 149 on-patent drugs. On these drugs, Medicare and Medicaid spent a total of $28.3 billion in 2020. Adopting indication-specific pricing reduced drug prices by an average of -2.9% with cost savings of -$4.4 billion (-15.5%). Spending was particularly reduced on orphan drugs treating rare and common diseases, e.g. partial orphans (-10.0%). However, higher prices for ultra-rare diseases increased spending by 16.8% (+$44 million). Adopting weighted-average pricing also reduced spending by -$4.4 billion (-15.5%). Weighted-average pricing reduced prices for and spending on ultra-rare diseases by -21.3%.
Conclusions
Indication-specific and weighted-average pricing could help to align new indications’ value and price; thereby reducing Medicare and Medicaid’s expenditure on cancer drugs with multiple indications.
