Health Technology Assessment Challenges Associated with Tumour-Agnostic Technologies

Article by: Nadine Henderson and Lotte Steuten

A paradigm shift is occurring in cancer care with the introduction of tumour-agnostic therapies, for which the indication is defined by the molecular signature of the tumour rather than by its location. While promising for patients, healthcare systems are facing major challenges with the clinical and economic assessment of such therapies and subsequent reimbursement decisions.

As several agents have already gained regulatory approval, and many other emerging molecules are set to enter the market over the next decade, there is a window of opportunity to learn from the various approaches undertaken to date and prepare for more consistent assessments in the future.

To support that, we set out to better understand how entrectinib and larotrectinib have been assessed by seven HTA agencies internationally (Canada, Denmark, England, France, Germany, Scotland and Sweden) and to derive learnings from these assessments.

We found that across HTA agencies different evidence requirements and criteria were used to assess tumour-agnostic therapies, and that these influence the assessment and reimbursement decisions for tumour-agnostic therapies. Unsurprisingly, uncertainty about the clinical data was among the biggest concerns by payers, especially when non-traditional data sets were used, and this contributed to negative or partial funding recommendations in some countries. The option of conditional reimbursement to manage uncertainty, which exists in some but not all countries, may allow acceptance of currently available evidence with the caveat that additional data should be provided at an agreed later date.

Considering the different approaches to the clinical and health economic assessments, there is a need for more guidance on how HTA assessments and economic models should be structured for future tumour-agnostic molecules. Currently, countries that reject therapies solely because of uncertainty in the clinical data, but neither allow RWD in submissions or do not provide clear directions on how to generate acceptable RWD, nor have post-launch arrangements where RWD could be generated, do not seem to help themselves or patients very much. Some HTA systems however have developed, or are in the process of developing, internal guidelines for the assessment of tumour-agnostic therapies. This is a necessary and useful approach to ensure that future tumour-agnostic therapies are assessed consistently.
