Background

Interest and knowledge about the genetics and biology of inherited risk of and progression of disease is growing. Physicians are increasingly using tests and technology, including germline genetic, genomic, and biomarker testing, to provide insight into a healthy individual's risk and an affected individual's disease characteristics, in order to provide personalized clinical management. However, many barriers to adoption of precision medicine still exist in the clinical setting, including rapid advances in technology and research, complex guidelines for eligibility, variable quality and cost, and adequate understanding of appropriate implementation by medical professionals.

Methods

The iGAP Registry uses an innovative digital platform to collect genetic, genomic, biomarker data and correlates it with clinical, pathologic and outcome data to inform providers of an individual’s risk of developing cancer, guide them to appropriate clinical grade testing and provide clinical decision support to providers for prevention and management strategies over time. The iGAP Registry’s digital platform minimizes technological barriers to longitudinal research participation and is available in mobile and desktop formats, allowing for easy implementation in a wide variety of clinic and hospital settings.

The risk tool uses predictive analytics to identify and curate patients at risk who are eligible for initial and further testing. The tool additionally can generate letters of medical necessity, each individualized by personal and family history, for eligibility for genetic testing (based on national guidelines) and additional imaging (based on validated cancer risk calculators). The insights tool provides physicians with decision support on how to interpret and manage abnormal genetic testing results on an individual level and supports improved understanding across lab terminology through variant classification. The insights tool also supplies letters of medical necessity and supporting evidence across many specialties.

The platform connects the information stored in the risk and insights tools to a unique participant record and automatically feeds the data into a digital case report form for the research registry. Additional clinical data is entered for patients who consent to be a part of the Registry. This allows for seamless longitudinal data collection over time without disrupting typical clinical workflows, and is further enriched by emailed patient-reported outcomes and physician decision impact questionnaires. Follow-up occurs over 5 years after initial data entry for the 10,000 expected subjects in the Registry (Table 1).

Conclusion

The iGAP Registry is a multi-center longitudinal, observational research database with an integrated platform of clinically-useful tools designed to address gaps for providers specifically for identifying individuals at elevated risk based on clinical and pathologic factors, guiding them to appropriate genetic, genomic, and biomarker testing and providing clinical insights on actionable results for personalized management and prevention for the individual and their family members over time. The iGAP Registry is currently enrolling and accepting new sites at www.igapregistry.org or https://clinicaltrials.gov/ct2/show/NCT04419896.
