Welcome to PATH Builder

PATH (Preclinical Assessment of Translation to Humans) is a structured approach for presenting a comprehensive, accurate and transparent scientific rationale for early phase clinical trials and innovative care. Read the PATH paper (Kimmelman et al, 2024) for a detailed rationale and worked examples.

Save and export options

Save this PATH as a JSON and you will be able to edit it again using PATH Builder

SVG export will only include the image of the PATH figure

Word export will only include the text of the PATH summary

Define your target scenario

The main task for assessing a proposal is to determine the level of confidence that a drug, when given to a target population, will produce a desired response. We call this the "target scenario."
