Concept of a Signature State A State B Gene expression analysis
Gene Expression Profiles As Surrogates for Biological Phenotypes
Gene Expression Profiles As Surrogates for Biological Phenotypes Gene expression profiles as a common currency for in vitro and in vivo phenotypes
The Challenge of Personalized Cancer Treatment • How to improve prognosis to identify the patients in need of further treatment? • How to identify more effective therapeutic opportunities tailored to the individual patient? Who to treat? How to treat?
Improved Prognosis Using Genomic Signatures Use to refine clinical prognosis But - how to find an opportunity to actually use the refinement
Early Stage NSCLC Treatment Protocol Stage 1a: Observation Stage 1b-3: Adjuvant Therapy Diagnosis Tumor is resected and measured Yet, 25% of Stage 1A patients will recur and die - how to identify these individuals?
A Genomic Predictor of Recurrence Low Risk High Risk Predicted High Risk Probability of Recurrence Predicted Low Risk
Validation of the Genomic Recurrence Predictor CALGB samples Accuracy: 79%
Standard-of-Care • Cisplatin/vinorelbine • Cisplatin/gemcitabine • Cisplatin/docetaxel • Carboplatin/paclitaxel Only a fraction of patients will respond The rest are treated ineffectively How to choose the right therapy for the individual patient?
Herceptin - The Importance of Patient Selection All Breast Cancer Patients Her2+ Breast Cancer Patients Herceptin Herceptin < 10% Response 35-50% Response Can we do the same for commonly used chemotherapies?
A Strategy to Predict Response to Cytotoxic Chemotherapies NCI-60 Cell Panel Drug response data Affymetrix expression data • Identify resistant and sensitive cells • Build expression predictor of response Resistant Sensitive
A Panel of Predictors for Cytotoxic Chemotherapies Docetaxel Topotecan Adriamycin 5-FU Taxol Cytoxan
Predicting Patient Response to Cytotoxic Chemotherapies Paclitaxel Topotecan Adriamycin Probability
Patterns of Predicted Sensitivity to Cytotoxic Chemotherapies Predict drug sensitivity in tumors Etoposide Paclitaxel 5-FU Adriamycin Topotecan Cytoxan Docetaxel Distinct patients sensitive to etoposide and paclitaxel
An Opportunity to Guide Therapy Random Selection A or B Outcome Standard of Care (A or B) Genomics-Guided A or B Outcome Cisplatin/gemcitabine Cisplatin/docetaxel A B Beyond standard of care - how to direct targeted agents?
