Surrogate outcome decision support tool

Web-based Appdemo✓ Source-grounded

A web-based tool designed to help health technology assessment (HTA) agencies and payers decide how to handle evidence from surrogate endpoints, like lab results or biomarkers, when evaluating medical treatments. It supports more informed decisions when direct evidence on patient outcomes is not available.

At a glance

Use when

Evaluating new treatments with early or limited clinical data, especially when surrogate endpoints are the primary evidence source

Avoid when

Direct evidence on patient-relevant outcomes is available, or when the surrogate-clinical outcome link is weak or unproven

Inputs

Information on the surrogate endpoint, clinical context, strength of evidence, regulatory status, and disease characteristics

Outputs

Guidance on the appropriateness and limitations of using surrogate endpoint evidence in decision-making, including recommendations for evidence development and uncertainty management

How it works

The tool was developed based on findings from four empirical studies within the COMED program and integrates insights from international HTA practices and methodological literature on surrogate endpoints. It provides a structured framework to assess the validity and relevance of surrogate endpoint evidence in the context of HTA, supporting decision-making under uncertainty.

Assumptions
The surrogate endpoint is biologically plausible and has some established correlation with clinical outcomes; long-term outcome data are unavailable or immature; decisions must be made under time pressure
Strengths
Based on empirical research and international HTA practices; supports structured, transparent decision-making; designed for use by diverse HTA stakeholders including clinicians, patients, and manufacturers
Limitations
Does not replace clinical trial data; utility depends on user interpretation; limited validation data so far; not a standalone approval tool
Also known as
