  2. CANCER THERAPY ERAS • Locoregional treatments yrs ’40 -’50 • Chemotherapeutic- based yrs ’60 -’80 • systemic treatments • Targeted treatments current yrs • Genomic-based treatments the era is beginning

  3. EVOLUTION OF SYSTEMIC THERAPY IN ADVANCED NSCLC Gefitinib 2004 Docetaxel 2003 First-line Second-line Third-line Not approved Erlotinib2005 Maintenance Pemetrexed 2004 Docetaxel 2000 Paclitaxel Gemcitabine 1998 Bevacizumab 2007 Pemetrexed 2008 Vinorelbine 1997 Gefitinib 2009 12+ Carboplatin 1989 Pemetrexed 2009 Cisplatin 1978 Median overall survival, months ~8–10 Erlotinib 2010 ~6 ~2–4 1970 1980 1990 2000 2010 Bevacizumab + PC Best supportive care Single-agent platinum Doublets Histology-direct therapy European Medicines Agency. http://www.ema.europa.eu/ema/index.jsp?curl=/pages/home/Home_Page.jsp

  5. NSCLCDifferenthistotypes: Differenttreatments Squamous cell ( NO Bevacizumab) Non Squamous cell (Pemetrexed)

  6. CHARACTERISTICS OF THE NSCLC TUMORS ACCORDING TO THE VASCULAR PATTERNS (a vascular pattern)

  7. ALVEOLAR PATTERN The onlyvesselsevident in this pattern arisefrom the alveolarsepta

  9. THE TUMOR OF EACH SINGLE PATIENT IS UNIQUE BECAUSE THE GENOME OF HIS/HER CANCER IS UNIQUE

  10. THE SWITCH FROM HISTOLOGIC TYPE TO MOLECULAR CLINICAL ONCOLOGY:THERAPEUTIC IMPLICATIONS OLD PARADIGM NEW PARADIGM SUBCLASSIFICATION BY TARGET IDENTIFICATION DISEASE- DRIVEN THERAPY HISTOLOGY DRIVEN THERAPY HISTOLOGY DRIVEN THERAPY UNDERSTANDING THE MOLECULAR TAXONOMY: MOLECULAR DRIVEN THERAPY PRESUMED HOMOGENEOUS GROUP OF PTS PRESUMED HOMOGENEOUS GROUP OF PTS PRESUMED HOMOGENEOUS GROUP OF PTS SAME THERAPEUTIC REGIMEN SAME THERAPEUTIC REGIMEN SAME THERAPEUTIC REGIMEN PERSONALIZED THERAPY

  11. THE PARADIGM OF PERSONALIZED CANCER CARE: WHAT DOES IT MEAN? THE ASPIRATION TO BASE A TREATMENT ON THE UNIQUE BIOLOGICAL FEATURES OF A PATIENT’S DISEASE THROUGH THE IDENTIFICATION OF VALIDATED TOOLS OF RESPONSE/RESISTANCE TO THERAPY AIMS • TO IMPROVE DRUG EFFICACY • TO AVOID INAPPROPRIATE DRUG EXPOSURE (PRIMARY RESISTANT TUMORS) • TO MAXIMIZE QUALITY OF LIFE • TO SPARE UNNECESSARY COSTS

  12. THERAPEUTIC TARGETING OF THE HALLMARKS OF CANCER Hanahan  Weinberg, Cell, 144:646, 2011

  13. MULTISTEP PATHOGENESIS OF INVASIVE LUNG ADENOCARCINOMA Invasive ADC Poor Prognosis ADC Cancer J Clinicians,61:91,2011

  20. THERAPEUTIC RESISTANCE TO KINASE INHIBITORS Gatekeeper mutations near to kinase active site • Additional mutations in the target oncogene • Gene amplification • Upstream mutations activating the target oncoproteins • Bypass mechanisms involving alterations that dysregulate a cellular effector acting in parallel to the drug target Wagle et al, JCO;29:3085, 2011

  21. FREQUENCIES OF INTRINSIC RESISTANCE TO EGFR-TKIS RELATIVE TO SENSITIVITY/RESISTANCE IN NSCLC

  22. DIAGNOSTIC FEATURES OF EML4-ALK-POSITIVE NSCLC FISH H&E ALK HIC • The frequency of EML4-ALK ranges from 1.5% - 6.7% (Asian) to 13% (White) to 33% • (never/light smokers without EGFR mutation) • EML4-ALK pts are more likely to be men (23% vs 9%) • EML4-ALK pts are significantly younger than EGFR or WT/WT pts • EML4-ALK–positive tumors appear histologically distinct from EGFR mutant and WT/WT tumors Shaw, AT, et al. J Clin Oncol; 27:4247-53 2009

  23. PERSONALIZED THERAPY: EMLA4-AKT NSCLC

  26. SQUAMOUS CELL CARCINOMA OF THE LUNG In 63% of lung SCCs we can now identify a possible therapeutic target Targets will need to be validated in pre-clinical models FGFR1/2, PIK3CA and DDR2 inhibitor trials are planned or ongoing Hammerman P. et al. Proc. IASLC 2011

  27. WHICH STRATEGY FOR SEQUENTIAL TREATMENTS TO MAKE A TUMOR A CHRONIC DISEASE

  28. STEPS FOR MATCHING EACH CANCER WITH INDIVIDUALLY TARGETED THERAPY Haber et al, Cell, 145: 19, 2011

  29. SEQUENTIAL THERAPY OF ADVANCED DISEASE EMPIRIC APPROACH PHARMACOGENOMIC APPROACH Use presumednon-cross resistant cytotoxic agents Biopsy-obtained updated genomic characterization (eg, secondary mutations, gene amplification, epigenetic alterations, …) NSCLC 1st line Cisplatinum-based Therapy 1st line Gefinitib/Erlotinib in EGFR m tumors • 2nd line Therapy • Docetaxel • Pemetrexed • Vinorelbine 2nd line Therapy Selective agents to T790 mutation-WZ4002 c-MET inhibitors Irreversible anti-EGFR agents

  30. THE BATTLE TRIAL: PERSONALIZING THERAPY FOR LUNG CANCER – STUDY DESIGN Kim et al, Cancer Discovery, 1:43, 2011

  31. THE BATTLE TRIAL: PERSONALIZING THERAPY FOR LUNG CANCER – RESULTS

  32. PHARMACOGENETICS and clinical utility Genetics Individualized drug Minimize Toxicity PHARMACOGENETICS AIM Maximize Efficacy Pharmacology Individualized dosing

  33. A FLIGHT ON FUTURE YEARS • NEW STRATEGIES FOR KILLING CANCER STEM CELLS 1 • ULTRA-SELECTIVE ANTICANCER DRUG DELIVERY BY NANOTECHNOLOGIES (Nanoporous particle-supported by lipid bilayers) 2 • NEW COMPREHENSIVE CLASSIFICATION OF NSCLC BASED ON GENOMIC ABNORMALITIES ACCOUNTING FOR ALL THE MUTATED CANCER GENES PRESENT IN A SINGLE TUMOR • PIVOTAL TRIALS IN GENOTYPE – DEFINED SUBGROUPS 1 Lang, Cancer Cell, 20: 341,2011 2 Ashley, Nature Materials,10: 389, 2011
