This document provides an agenda and overview from a conference on generating evidence and assessing the value of stratified medicines and diagnostic tests. The summary includes:
1. The conference discussed elements of value for diagnostic tests, including reducing adverse drug effects and uncertainty about treatment value.
2. Institutional arrangements for assessing diagnostic value were examined, including joint drug-diagnostic assessments and diagnostic-specific processes.
3. Generating evidence to link diagnostics to patient value and incentivizing uptake were areas of focus, with examples provided.

9. Aligning incentives
• Greater willingness on the part of payers to accept prices that reflect
value
• Will involve a need for price flexibility for drugs as evidence of their
value for different groups of patients emerges over time
• Consideration of some form of intellectual property protection (e.g.
data exclusivity) for diagnostics to cover evidence of clinical utility
• Realistic expectations about standards for evidence. This involves the
use of CED and real-world evidence collection for both drugs and
diagnostics
• Public investment to complement the efforts of payers and
manufacturers, recognising the limitations on the incentives for both
to invest in evidence collection on all the questions that matter.
