  4. Oncogenic Driver Mutations Impact Anticancer Therapy in Humans Lung Cancer Melanoma IPASS NEJM ‘09 Ph II Trial PLX-4032 PASCO ‘09

  5. Evolution of Knowledge About ‘Driver Mutations’ in Non-Small Cell Lung Cancer Pao and Girard ’11

  6. Spectrum of ‘Driver Mutations’ in 202 East Asian Never Smokers with Lung Adenocarcinoma Li et al ‘11

  7. Molecular Subsets  Progress

  8. Goals of the VICC PCMI - 2009 • To establish ‘reflex’ testing of ‘common’ clinically relevant genetic alterations in lung cancers and melanomas • To develop a clinically-applicable high-throughput molecular genotyping facility for ‘rarer’ genetic variants • To develop bioinformatic algorithms to report genetic results in the electronic medical record in ways that are clinically useful for practicing oncologists • Collaboration among Depts of Medicine, Pathology, BioInformatics, and VICC

  9. What Test? What Should Be in the Test? • Which platform? • SNaPshot (ABI 3730) vs new technology (Sequenom) • Ease of calls • High sensitivity • One panel for all cancers? Or tumor-specific panels? • Feasibility vs. wide-applicability • How often does one really find an ‘actionable’ mutation (e.g. EGFR kinase domain mutation in a melanoma)? • Which mutations? • Occurs in the cancer • Occurs with frequency >1% • Has relevance to existing or emerging targeted therapy

  10. How to Implement? • Molecular diagnostics • Assays developed in Pao Lab as collaboration with CLIA-lab • Assays transferred to/re-validated by CLIA-lab • Bioinformatics • Monthly meetings among Bioinformatics, Pathology • Input from practicing clinicians • Pathology workflow • Re-organization/tissue librarian • Education • Consent • Lung – reflex • Melanoma – consent form

  11. One Size Does Not Fit All:Melanoma/Lung Ca Molecular Profiling Results 7/1/10-12/31/11 Melanoma Panel: 538 Samples Lung Panel: 451 Samples Cindy Vnencak-Jones

  12. First 150 Patients: 20% of BRAF V600 Mutations Would Be Missed by Allele-Specific PCR First 150 Patients: 20% of BRAF V600 Mutations Would Be Missed by Allele-Specific PCR Lovly, Dahlman, Fohn, Su et al‘12 Lovly, Dahlman, Fohn, Su et al‘12

  13. First 150 Patients: 40% of Pts with Mutant Metastatic Disease  Genotype-Driven Treatment *This CTNNB1 mutation (CTNNB1 S45P) occurred concurrently with an NRAS Q61L mutation. Lovly, Dahlman, Fohn, Su et al‘12

  14. Kinase Fusions in Human Cancers 43-350 222 GXGXXG GXGXXG GXGXXG GXGXXG 117 83 18-62 48-79 # amino acids to fusion GXGXXG GXGXXG GXGXXG 44-64 JAK2 70-201 GXGXXG ABL1 ROS1 NTRK1 BRAF PDGFR 56 GXGXXG Exon (-2) Exon (-1) Exon* ALK RET FGFR1 15-33 15 GXGXXG GXGXXG PDGFR NTRK3 intron (-3) intron (-2) intron (-1) *encodes GXGXXG motif Chmielecki et al ’10; Chmielecki et al ‘11

  16. Novel C6orf204-PDGFRbeta Fusion in Pt with Recurrent T-ALL and MPN Chmielecki et al ’10; Chmielecki et al ‘11

  17. Summary – Building a Sustainable Model • Impact in the clinic • Prioritize treatment options for existing targeted therapies • Impact on clinical trials • Accelerate accrual to trials with emerging targeted therapies • Enrich for cohorts of pts likely to benefit • Impact on translational science • Create opportunities from the bedside to bench and back • Initiate new projects

  18. Goals of the VICC PCMI - 2009 • To establish ‘reflex’ testing of ‘common’ clinically relevant genetic alterations in lung cancers and melanomas • To develop a clinically-applicable high-throughput molecular genotyping facility for ‘rarer’ genetic variants • To develop bioinformatic algorithms to report genetic results in the electronic medical record in ways that are clinically useful for practicing oncologists • Collaboration among Depts of Medicine, Pathology, BioInformatics, and VICC

  19. Knowledge Gap 94% of community oncologists responded that they discuss genetic mutation testing with their patient 17% of lung cancer patients were aware of genetic mutation testing 44% of oncology nurses did not discuss genetic mutation testing with patients, because they felt they lacked knowledge to discuss it

  20. Old Method for Reporting Mutation Results in the Electronic Medical Record Old Method: • Report Template • Scanned into Electronic Health Record as image file (not computable) Challenges: • How to report > 40 mutations in 8 genes? • Whose role to curate knowledge regarding clinical significance? • Lack clinical trial information

  21. New Method for Reporting Mutation Results in the EMR Mia Levy

  36. Future Directions • DETECT – DNA Evaluation of Tumors for Enhanced Cancer Treatment • Breast ca, colon ca using SNaPshot • NGS on ‘pan-negative’ cases • Develop in-house next-gen panels • Partner with Foundation Medicine, MolecularMD • MyCancerGenome.org – Web-based decision support • Expand content; monthly updates • DIRECT – DNA-mutation Inventory to Refine and Enhance Cancer Treatment • We need a national effort: COSMIC for clinicians • MCG – Drug Compendium

  37. Sanford Guide to AntiMicrobrial Therapy

  39. 2 Issues • DIRECT • Journals and/or the NCI should mandate that for genotype-directed clinical trials, ALL individual level patient data, including genotypes, MUST be reported in a public fashion! • FDA-mandated companion diagnostics vs multiplexed assays • Tissue • $ • Time • Lung cancer: EGFR, HER2, PIK3CA, ALK, ROS, RET, etc.
