Challenges in the value assessment, pricing and funding of targeted combination therapies in oncology

The use of targeted combination therapy (TCT) is becoming the standard of care in oncology as cancers are attacked through multiple inhibition mechanisms. TCTs pose a budget challenge to health systems and an economic return challenge for companies developing them.

We conducted a systematic literature review to identify challenges specific to TCTs and reviewed publicly available reports by health technology assessment and pricing and reimbursement bodies. We synthesized our findings into a problem map.

Challenges and policy solutions linked to TCTs remain almost fully unexplored; we identified few resources that explicitly addressed TCTs. Contributors to the budget challenge are found at different layers; they and include static willingness-to-pay (WTP) for TCTs and inefficiencies in managing prices of backbone therapies. Economic return challenges are related to payer-imposed restrictions, peculiarities of TCT development, and conflicting incentives of pharmaceutical companies that own constituent therapies. Consequences are delayed or restricted patient access to TCTs, disincentives for research and development, and fewer life years gained.

Multiple issues will lead to the unsustainability of funding systems and possible conflict between stakeholders around access to TCTs. To manage these, new value assessment and attribution methodologies, modified trial designs and differentiated WTP thresholds can be considered in ways that are customized to the characteristics of different health systems.
