Early Implementation through Efficient Clinical Trial Design In addition to collaboration with government bodies via the priority review designation, this clinical trial adopts the following optimized design: - Reduction of patient burden: Adopts a protocol that minimizes test items and requires only one clinic visit. - Balance of speed and cost: Realizes significant timeline reduction and cost savings compared to traditional clinical trials through process simplification.

Future Outlook ExaMD aims to maximize the benefits of the priority review designation to obtain manufacturing and marketing approval and commence sales within FY2026.
