A potential for seamless designs in diagnostic research could be identified

Area of Science:

• Diagnostic research
• Clinical trial design

Background:

• Diagnostic test development traditionally involves sequential studies with significant time gaps.
• This lengthy process delays clinical implementation and reimbursement.

Purpose of the Study:

• To investigate the potential of seamless designs in diagnostic research.
• To identify challenges and opportunities for integrating various study types.

Main Methods:

• Identified major study types in diagnostic research (e.g., variable construction, accuracy studies, change-in-management studies).
• Analyzed characteristics relevant to seamless designs, including recruitment, reference standards, comparators, and outcomes.
• Identified key hurdles and opportunities for seamless designs.

Main Results:

• Two primary hurdles exist: combining accuracy and post-accuracy studies, and the placement of randomized diagnostic studies.
• Significant potential exists for combining multiple study phases (e.g., construction to comparison) within one protocol.
• Seamless designs can accommodate changes in recruitment and study type (e.g., single-arm to comparative accuracy).

Conclusions:

• Seamless designs offer substantial potential to accelerate diagnostic research.
• Holistic planning of the entire study sequence is more effective than individual study planning.
