Vision Cancer will either be curable, or manageable as a chronic sub-acute disease, and imaging will be central to its management through the use of validated IB.
Vision 2025 • Socio-economic benefit • Paradigm • Clinical focus/relevance • Performance • Roadmap
Socio-economic benefit (cheaper/better/faster) • Less expensive/time consuming development: • Lower delta t and/or N for same statistical power • Manage cancer as chronic (personalized, sub-acute) disease • Clinical care (opportunity for strategic intervention, reduction in errors, side effects, survival) • Pt is treated correctly for their disease.
Paradigm • On the day you are born, health management begins (prediction) • Prevent, and treat early disease (not late) • Prevention strategies well developed, i.e., avoidable, reversible, manageable • Every patient that comes in the door will give a piece of themselves from which ‘omic data are derived • Deal effectively with heterogeneity • Early stratification of patients at risk • Image is among a wide array of complementary assays that are well integrated • Therapy is non-toxic and completely local • Not just systemic treatments, include targeted minimally invasive surgical, ablative, brachytherapy, etc. • Change patient experience, error prone, expensive… more efficient scans and diagnosis (pay for performance) • Bioinformatics infrastructure robust and clinical data ubiquitous
Clinical focus/relevance • Imaging for least intrusive window into pre-symptomatic phase of disease • Effective imaging signatures for hallmarks of pre-symptomatic disease (both resolution and sensitivity) • “virtual biopsy” • Complementary benefit of other biomarkers need effective data fusion approaches (incl. decision support) • Genotyping->prevention (risk markers) • Correlations between modality • Imaging used both to stratify and to make adaptive therapy personalized to pt • Tx is highly localized, image guided, no side effects Ask better questions: move full community beyond just asking whether we can detect a tumor
Performance (the science of measurement as opposed to picture taking) • Standardization and iterative improvement: • Variance reduced: • Human (e.g., protocols, compliance, structured reporting with quantitative endpoints) • Sigma reduced through technology developments • Calibration (incl. public data to calibrate against) (phantoms) • CAD (as a way to reduce variance) • Statistical framework for qualification established • Multi-disciplinary approach to validation/qualification of imaging methods • Device vendors (both HW and SW) market product certified against qualified Profiles • Qualification data shared across vendors 510ks and biopharma NDAs (cross registration) (conformance checks established) • Results easily accessible (includes unsuccessful agents, not just positive) • Cancer centers should have conformance checking process, too • Practice/workflow accounts for QI • Methods worked out that make it easy to do (CAD) • All imaging results embedded in EMR Clinical imaging = Quantitative imaging
Roadmap: Year 1 • Start incorporating QI in clinical trial approval process , first candidate markers used in trial designs (contributed by UPICT and QIBA) • Build infrastructure in comunications: • Approach to data sharing (needs to be linked to national agency initiatives) (build linkage to caBIG, etc.) (needs to be able for regulatory agencies to access and use) • Establish lines of communication (incl. celebrate models of success) (incl. strategy re: publishing) • Engage ASCO, ASTRO, • Engage top-management of device companies and biopharma • Include QI in RFAs from NIH • Define regulatory approval pathway (target: February 2010 meeting) • Continue IRAT (and similar) through extramural funding
Roadmap: Year 3 • Establish the qualification model (that is, Integrating the Imaging Biomarker Enterprise “IIBE”) (what QIBA is actually working on) • First marker through qualification process (a NDA/PMA type process) (e.g., FLT, vCT) (the “predicate”) • Dynamic imaging with PK/PD analysis in place (e.g., hypoxia, angiogenesis, apoptosis, metabolism) (from anatomic/structural to functional/dynamic) begun • Engage CMMS • Variance reduction efforts active and understood • Incl. standardization of image acquisition, and processing • Process of defining decision trees based on QI established and in use (structured reporting)
Roadmap: Years 5-10 • 5 • First commercial product shipped with certified marker via 510(k) (using the cross-reference) • Make quantitative imaging part of every appropriate clinical trial • Get payers to reimburse QI • QIN up and running • Structured reporting commonly used • Clinicians credentialed and “pulling” • Also it is in device tenders with buyers making decisions on it • 10 • Dynamic imaging with PK/PD analysis in common use (e.g., hypoxia, angiogenesis, apoptosis, metabolism) (from anatomic/structural to functional/dynamic) • National informatics infrastructure in place to support full quantitative biomarker with meta-data
