Summary
Physician-administered drugs like Keytruda significantly increase insurer spending. Provider revenues are substantial, with higher markups in 340B-eligible hospitals compared to non-eligible hospitals and physician practices.
Area of Science:
- Health Economics
- Oncology Drug Markets
- Pharmaceutical Policy
Background:
- Physician-administered drugs and biologics represent a growing segment of pharmaceutical expenditure.
- These high-cost therapies generate significant revenue for healthcare providers through price differentials between acquisition and reimbursement.
Purpose of the Study:
- To analyze insurer expenditures and provider margins for Keytruda, a leading biologic.
- To quantify revenue generation across different healthcare settings (340B-eligible hospitals, non-eligible hospitals, physician practices).
Main Methods:
- Analysis of detailed insurer, provider, and market data for 59,717 patients treated with Keytruda.
- Examination of expenditures and price markups from 2020 to 2024 across 5,008 healthcare facilities.
- Calculation of provider revenue per patient adjusted for various factors.
Main Results:
- Private insurer expenditures for Keytruda surged by 142% from 2020-2024, with patient numbers rising 110%.
- Average price markups for Keytruda were 173% in 340B-eligible hospitals, 78% in non-eligible hospitals, and 16% in physician practices.
- Annual revenue per Keytruda patient was $102,680 (340B hospitals), $67,825 (non-eligible hospitals), and $3,094 (physician practices).
Conclusions:
- Significant provider revenue is generated from Keytruda, particularly in 340B-eligible hospital settings.
- Reimbursement structures create substantial financial incentives for providers administering high-cost biologics.
- Understanding these economic dynamics is crucial for pharmaceutical policy and healthcare cost management.

Drug Products: Biologics, Biosimilars and Interchangeables
Biologics, derived from living sources such as humans, animals, or microorganisms, represent a significant category of pharmaceuticals. These complex molecules, developed through advanced biotechnological methods or purified from natural sources, include essential medical treatments like insulin and growth hormones. The complexity of biologics arises from their large molecular structures and the intricate processes required for their production, making them distinct from conventional...
Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
