3. Advanced Imaging for Clinical Trials Examples of advanced imaging
Target-specific PET
FLT for cell proliferation
Cu-64 ATSM for hypoxic regions
Alzheimer-specific amyloid targeting
DCE-MRI for anti-angiogenic and vascular destructive agents
MRS
Lipids for hepatic fat content
Glutamate for glioblastoma
Noble gas MRI imaging for destructive lung diseases
4. Advanced Imaging Unique information to guide drug development
Across all therapeutic areas
At all phases of clinical research
Properly employed imaging:
Mechanisms of action
Early assessment of effectiveness
Fewer subjects
Faster trial completion
More accurate drug development decisions
Lower drug development costs
5. Imaging Innovation Progressing Rapidly Major shifts in imaging innovation:
Gross anatomy/pathology to cellular and subcellular imaging
Anatomic to functional imaging
General functional imaging to imaging specific targeted receptors
Qualitative to quantitative
The linking of diagnostics to therapeutics
6. P4 Medicine Promoting Imaging Innovation Predictive of individual patient risks to support better disease surveillance
Preemptive diagnosis and treatment to improve outcomes
Personalized diagnosis and treatment based on history and the genome
Participatory care in consideration of patient preferences
7. Imaging and P4 Medicine Predict susceptibility to specific diseases
Predict biological aggressiveness/treatability
Predict susceptibility to treatment
Determine likelihood of toxic effects
Monitor response to treatment early and accurately
Link surveillance, diagnosis, staging, and treatment in an efficient, convenient, patient friendly paradigm to aid accrual
8. The Future of Imaging and Trials The year is 2020
26 year old Nancy Wardby evaluated for a trial of pancreas cancer prevention
Omniscient exam
Safe radiant energy discovered
during the 2002-18 Middle East wars
Safe gaseous contrast agents
9. The Omniscient The Omniscient:
Predicts predilection for serious disease
Determines if the disease is present and biological aggressiveness
Stages the extent of disease
Predicts whether the experimental agent will be effective
No discomfort or convalescence
Convenient, one-stop technology for risk assessment through curative treatment
Expensive
10. The Omniscient Omniscient scans become routine practice in clinical trials because
Selects subjects
At greatest risk of contracting target disease
Most likely to need treatment
Most likely to respond to the specific therapeutic agent
Improves accrual
Fewer subjects, faster trials, lower costs
11. The Benefits of Imaging Applicable across all imaging applications and all therapeutic areas
Earlier, more accurate assessment of response
Non-invasive and repeatable
12. Applicable in All Phases Phases I/II
Mechanisms of drug activity
Evaluate suspected pathways
Identify possible alternative applications
Insight into efficacy
Possible evaluative approaches to later phase trials
Key information for go/no go decisions
13. Applicable in All Phases Phases III/IV
Assessment of effectiveness
Assessment of safety
Surrogate endpoint for FDA submissions
RECIST (effectiveness)
MRS of hepatic fat content (safety)
14. The Pharmaceutical Industry Challenge
15. Imaging and Efficiency
16. Advanced Imaging for Clinical Trials More effective and efficient clinical trials
Requires expertise:
Applications and protocol development
Technical understanding of acquisition. processing, quality assurance, and interpretation/measurement
Normalization
Standardization
Measurement methods and reduction in variability
Sophisticated data extraction tools
