The Role of Personalized Medicine in our Future Delivery System
Christine Cournoyer, Chief Executive Officer, N-of-One
Challenges
•NCCN Guidelines address the treatment needs of limited number of patients
•Knowledge of additional markers and therapies isn’t readily available to the physician at the point of care
•Reimbursement for additional testing and therapies is a key challenge
•Access to the drugs and clinical trials can be time consuming and difficult
Broader testing and guided therapy can offer improved alternatives to cancer patients failing the standard of care
Evidence to support exploration of additional therapies
• Both the literature and N-of-One experience reflect the high percentage of actionable biomarkers that are not included in NCCN guidelines.
• Expanded testing and clinical interpretation of results can guide physicians to more biomarker-directed therapies
• Larger patient studies are beginning to support improved clinical outcome of individualized strategies based on molecular test results for cancer treatment
Integration of more molecular testing could transform individualized cancer care.
•NCCN Guidelines impact only about 14% of Caucasians who test positive for EGFR (10-15%) and ALK (4%) leaving a large population of lung cancer patients (~80%) without access to targeted therapy options.
Does this matter?
•A growing number of studies, N-of-One data and patient cases in lung cancer support the premise that access to additional targeted therapies beyond the NCCN guidelines may lead to improved outcomes.
Lung adenocarcinoma as an example of the need for expanded testing and personalized cancer care
Lung Cancer Mutation Consortium Protocol: evidence for biomarker-directed therapy in lung cancer
Oncogenic drivers were identified in 466 of 733 patients tested for 10 biomarkers (64%) from 2009-2012.
(KRAS, EGFR, ALK, ERBB2, BRAF, PIK3CA, MET, NRAS, MEK, AKT1)
Oncogenic drivers were identified in 578 of 938 patients tested for at least 1 biomarker (62%).
260 with actionable biomarker
Biomarker-directed therapy
3.5 yr median survival
318 with actionable biomarker
No biomarker-directed therapy
2.4 yr median survival

N-of-One Data collected over a 1-year period supports biomarker testing in lung adenocarcinoma
Clinical actionability in lung adenocarcinoma (n=211)
New Models Emerging to bring Precision Medicine to the Community:
Example: Intermountain Personalized Medicine Clinic• Intermountain, with the help of N-of-One, can offer physicians consulting on the appropriate use of molecular testing to guide additional diagnostic testing with evidence to support reimbursement
• Intermountain will provide the testing and clinical interpretation and present the results to their Molecular Tumor Board (MTB) for discussion
• Intermountain’s MTB can provide an analysis of the results and knowledge of available targeted therapies indicated for any actionable mutations.
• Intermountain can work with the patient on reimbursement and can provide drug procurement of the targeted therapy for the patient
Benefit: Patient receives precision medicine options in their community

“Precision Medicine” “The Future of Cancer Care”
“Targeted”, “Personalized”, or (most recently) “Precision” therapy
• Not a new concept• Hormonal therapy of breast/prostate cancer:
Earliest systemic anti-neoplastic strategy ER receptor discovered 40 years ago
• HER-2 over-expression in breast cancer• CML/GIST (profoundly different pathology but
similar molecular abnormalities resulting in essentially identical highly effective therapy)
• Resulting over-simplification of complex biology

“The difficult path forward …..”
• Inhibition of EGFR in lung cancer – unique mutation vs. simple over-expression
• Inhibition of EGRF in colon cancer – role of KRAS mutation defining lack of utility
• Small patient subsets – Difficulty proving clinical benefit, including for regulatory approval
• Evidence required for molecular markers• Insurers willingness to pay

But ….
• The future is here• It is possible today to sequence the entire
genome of a tumor and the corresponding normal genome (pharmacogenomics) of an individual cancer patient for < $5,000 (12-15 years ago this would have cost $6,000,000,000)
• So, the issue is not whether the data will be available to patients, but rather how to optimally convert this massive quantity of raw data into information of genuine value in individual patient management

Declining Cost of Sequencing a Human Genome
“The STEPS”
• Discovering the “code” in an individual patient– (“sequencing”) (easy)
• Attempting to break the “code” – (“bio-informatics) (difficult - extremely difficult)
• Exploring the relevance of the proposed solution (“clinical validation with a targeted therapeutic”) in individual patients (unknown difficulty)
• Proving the relevance of the solution (“n of one” research) (soon-to-be the new paradigm in clinical cancer therapeutic research)

Pharmacogenomics in Cancer Management
• Well-recognized variations in the severity of toxicities of anti-neoplastic agents between individuals and ethnic groups impacting:
• (1) quality of life;• (2) survival outcomes (ability to deliver a
sufficient concentration and total dose over time to produce the desired/optimal cytotoxic effect)

Proposed future research strategy
• Web-based national/international registry of outcomes (history, validated treatment results) from therapy based on molecular-based management – (“n-of-one” research) (“CancerLinQ”– ASCO (Schilsky; Nat. Rev. Clin. Oncol.) )
• Results made available to all interested parties (public, patients, regulatory agencies, 3rd party payers, employers, research community)
• When robust data available, publication in peer-reviewed literature
