The Value of New: Consideration of Product Novelty in Health Technology Assessments of Pharmaceuticals.

ABSTRACT

BACKGROUND: Efforts to understand how treatments affect patients and society have broadened the criteria that health technology assessment (HTA) organizations apply to value assessments. We examined whether HTA agencies in eight countries consider treatment novelty in methods and deliberations. METHODS: We defined a novel pharmaceutical product to be one that offers a new approach to treatment (e.g., new mechanism of action), addresses an unmet need (e.g., targets a rare condition without effective treatments), or has a broader impact beyond what is typically measured in an HTA. We reviewed peer-reviewed publications and technical guidance materials from HTA organizations in Australia, Canada, England, France, The Netherlands, Norway, Sweden, and the United States (US). In addition, we explored how HTA organizations integrated novelty considerations into deliberations and recommendations related to two newer therapies-voretigene neparvovec for an inherited retinal disorder and ocrelizumab for multiple sclerosis. RESULTS: None of the HTA organizations acknowledge treatment novelty as an explicit value criterion in their assessments of pharmaceutical products. However, drugs that have novel characteristics are given special consideration, particularly when they address an unmet need. Several organizations document a willingness to expend more resources and accept greater evidence uncertainty for such treatments. Qualitative deliberations about the additional unquantified potential benefits of treatment may also influence HTA recommendations. CONCLUSION: Major HTA organizations do not recognize novelty as an explicit value criterion, although drugs with novel characteristics may receive special consideration. There is an opportunity for organizations to codify their approach to evaluating novelty in value assessment.
