Interpretation of Imaging Data

3 Areas for discussion

• Central Read

• Validated tools to analyze data

• Data access, transfer, and dissemination

Existing Standards:

Protocol, Imaging Charter, Imaging Manual, 21CFR Part 11, FDA Guidance for Industry: Clinical Trial Imaging Endpoint Process Standards, FDA Guidance for Industry: Computerized Systems Used in Clinical Investigations, FDA Guidance for Industry: Electronic Source Data in Clinical Investigation, QIBA, QIN

(1) Central Read

Hypothesis: More efficient interpretation of

imaging data can be achieved through a

central read paradigm which supports remote

readers.

Standards for Remote ReadCharacteristic Remote Reader Approach

Access to images to read Controlled access, validated

Reader environment Dictated by sponsor/imaging

manual

Monitoring the readers Deploy staff, monitor via

webcam, shadow operator

Integration of other data for

presentation

Selective presentation to ensure

unbiased read

Capture of reader results Direct data entry to EDC, auto-

capture of data

(2) Validated Tools for Analysis

Hypothesis: Machine learning can lead to

increased efficiency in interpretation of

imaging data by expediting the process,

incorporating quantitative analysis tools, and

reduce human variability involved in the

process

AlgorithmZebra has developed an algorithm that

automatically calculates Coronary Calcium

Scores based on standard, non-contrast

Chest CTs. This tool can provide early

detection of people at high risk of severe

cardiovascular events.

Launch QtvApplication

Standards for more validated tools

• Can we validate algorithms/methods developed by the

community?

• What types of studies/analyses could benefit from

such capabilities?

• Is there a potential impact on reader study designs?

Could sufficient variability be eliminated to adopt

single reader model?

how do we ensure that such algorithms

will be accepted by FDA?

(3) Data Access and Transfer

Hypothesis: Data warehouses can create a

more efficient platform for interpretation of

imaging data for analysis, transfer, and

dissemination

Data access and dissemination

standards• Analysis

• Retrospective central read, or

• Concurrent access and reading?

• Transfer to Sponsor/FDA

• File transfer, or

• Access to reports and integrated source data?

• Future Research

• Proprietary or a community good?

• Project Data Sphere

Project Data Sphere

• Project Data Sphere, LLC (PDS), an independent, not-for-profit initiative of the CEO Roundtable on Cancer's Life Sciences Consortium (LSC), operates the Project Data Sphere platform, a free digital library-laboratory that provides one place where the research community can broadly share, integrate and analyze historical, patient-level data from academic and industry phase III cancer clinical trials.

• The Project Data Sphere platform is available to researchers affiliated with life science companies, hospitals and institutions, as well as independent researchers. Anyone interested in cancer research can apply to become an authorized user.

• A goal of the Project Data Sphere initiative is to spark innovation. The Project Data Sphere initiative can help the cancer community unlock the potential of valuable data by generating new insights and opening up a new world of research possibilities.

• The true power of this platform will come from an engaged, diverse and global community focused on advancing future research to improve the lives of cancer patients and their families around the world.
