Frequently Asked Questions

  • Monarch is an observational platform trial designed to support multiple independent research arms under shared governance and defined standards. It provides a common infrastructure for generating real-world evidence while preserving arm-level independence.

  • Yes. Monarch is an observational research platform designed to support the execution of a shared platform trial with multiple independent arms.

    Monarch provides the governance framework, standards, and infrastructure needed to capture, structure, and manage real-world evidence while preserving arm-level independence and methodological rigor.

  • Monarch is developed in partnership with the Alliance for Health Implementation Science (AHIS), which provides scientific and governance stewardship. Rabble Health provides the technical and operational infrastructure that supports execution of the platform trial.

  • Each trial arm operates under its own protocol, objectives, and boundaries. Shared governance standards ensure consistency in oversight, data stewardship, and publication integrity across the platform without coupling execution between arms.
