Solid Tumors Dominate the Early Oncology Pipeline. However, Hem/Oncand Hematology Products are More Evenly Distributed in Pipeline
♦ Although there are roughly 8 times the number of agents in development for solid tumors than for blood cancers in early stage, relatively few are bridging the Phase II “Valley of Death.”
♦ Novel agents for blood cancers appear more rationally based and developers use less of a “shots g pp y pon goal” clinical strategy.
♦ One trend to note: The number of programs pursuing “Big 5” tumors has decreased in recent years; more promising programs are using biomarkers to identify likely responder segments.

Cancer Genetics is Accelerating the Time from ‘Driver Mutation Discovery’ to ‘Clinical Proof of Concept’ and the Approval of New Drugs
♦ Gleevec received FDA approval long after the discovery of the Philadelphia chromosome mutation and hyperactive BCR‐ABL protein in CML.
♦ By contrast the more recent discovery of♦ By contrast, the more recent discovery of translocations of ALK in NSCLC has rapidly translated into registration trials for Crizotinib, a ‘cMET turned‐ALK’ inhibitor, based on tantalizing response rates in ALK‐fusion‐positive tumors (Phase I and II trial results).
♦ Likewise, the development paradigm for selective BRAF inhibitors, as exemplified by PLX4032, underlines the much faster pace of translation (8 years, compared with Gleevec or Herceptin) once the driver status (in h ) h d b bl h d f lthis case BRAF mutations) had been established for malignant melanoma.
♦ Such accelerated development times are enabled by the broader body of knowledge of cancer biology and mechanisms of actions that have been generated in the cancer field.

Encode Indicates that Gene Regulation is Far More Complex Than Previously Believed
♦ ENCODE, the Encyclopedia of DNA Elements, is a project funded by the NHGRI to identify all regions of transcription, transcription factor association, chromatin structure and histone modification in the human genome sequence.
20% f di DNA i th h i f ti l i l ti i ~20% of noncoding DNA in the human genome is functional in regulating gene expression 60% is transcribed with no known function. 90% of SNPs in sequences that are associated with various diseases fall outside of protein coding regions.
ENCODE investigators employ a variety of assays and methods to identify functional elements. The discovery and annotation of gene elements is accomplished primarily by sequencing RNA f di fRNA from a diverse range of sources, comparative genomics, integrative bioinformatic methods, and human curation. Regulatory elements are typically investigated through DNA hypersensitivity assays, assays of DNA methylation, and chromatin immunoprecipitation (ChIP) of proteins that interact with DNA, including modified histones and transcription factors, followed by sequencing (ChIP‐Seq).

Hematological Malignancies are Defined as Types of Cancer that Affect Blood, Bone Marrow and Lymph Nodes
♦ Hematological malignancies may derive from either of the two major blood cell lineages: myeloid and lymphoid cell lines.
Th l h id ll li The lymphoid cell lineage produces B, T, NK and plasma cells.
Cancers deriving from this lineage include lymphomas, lymphocytic leukemias and also myelomas.
The myeloid cell line normally produces granulocytes, erythrocytes, thrombocytes, macrophages and mast cellsmacrophages and mast cells.
AML, MDSs and MPDs are myeloid in origin.

AML is Mainly a Disease of Older Adults
♦ Acute myeloid leukemia (AML) is a life‐threatening disease in which hematopoietic progenitor cells committed to the myeloid lineage that normally develop into neutrophils, basophils, eosinophils, and monocytes become cancerous and infiltrates the bone marrow with rapid p , y pgrowth kinetics.
♦ 2012 US AML statistics:
Estimated new cases in US: 13,780
Expected mortality: 10,200
90% of new cases in adults
Average age at diagnosis >65 yrs♦ The disproportionate impact of AML on the
very old is evident in comparing the incidences in the entire US population and in people older than 75: 2.6 vs.16 per 100,000.
♦ The greater incidence in older adults may be due to cumulative exposure to carcinogens, radiation and chemotherapy for other malignancies, and also to improved screening

♦ FAB divides AML into subtypes, M0 through M7, based on the type of cell from which the leukemia developed and maturity based on microscopy after routine staining.
Sub classification % Diagnosed AML Characteristics PrognosisSub‐classification % Diagnosed AML Characteristics Prognosis
M0 5 very early cells, or blasts Poor
M1 15 some maturing cells Average
M2 25 mature cells with granules and "Auer rods" Good
M3 10called promyelocytic (APL); many granules and Auer rods in mature looking cells. treated with ATRA and chemotherapy, sometimes arsenic trioxide
Excellent
M4 25 called myelomonocytic; cells are mature Average to Excellent
M5 5 called monocytic because of cell appearance Very Poor
M6 5 called erythroid or DiGuglielmo’s syndrome; this is why not all AMLs are white blood cell diseases Very Poor

AML Prognosis Has Progressed from Clinical Criteria and Cytology…
Historically the most important prognostic indicators to base treatment decision include:♦ AML subclassification:
Diff t t f th b d d th lik l f th di d i b Different types of therapy may be used and the likely course of the disease and prognosis may be different.
Leukemias that express the progenitor cell antigen CD34 and/or the P‐glycoprotein (MDR1 gene product).
♦ Age and general health of Patient:
Increasing age is an adverse factor because older patients more frequently have a prior AHD and also co‐morbid medical conditions that compromise the ability to give full doses of chemotherapy.
Clinicians consider age 55 65 a general cut off when considering aggressive high dose Clinicians consider age 55‐65 a general cut‐off when considering aggressive, high‐dose chemotherapeutic treatment.
♦ Prior antecedent hematologic disorder (AHD):
An AHD such as myelodysplastic syndrome (MDS) is associated with a poor outcome to therapy.
♦ Prior Treatment:
High‐doses of anthracyclines, in particular, is important when assessing risk of cumulative dosing toxicities.

… To Molecularly Defined Risk Assessment
♦ Patients with a normal marrow karyotype are the largest cytogenetic subset of AML and are classified in the intermediate prognostic category, but not all patients benefited equally from these high dose chemotherapy.
♦ The likely reason for such variable response is the striking molecular heterogeneity of cytogenetically normal AML patients.

♦ Disease tends to be more treatment resistant in older patients, (de novo, antecedent MDS, sAML) with dramatically worse outcomes than in younger adults.
♦ Many studies have compared the option of best supportive care with that of a standard “3 + 7” induction regimen for older patients with AML which show trends toward improved survival when patients received chemotherapychemotherapy.
♦ However, it is important to be reminded of a sobering statistic—older patients with AML, usually defined in clinical trials as above 55 or 60 years of age, have a median time from treatment with 3 + 7 regimens to death of only 5‐10 months.

AML Leads Sequencing Efforts – Although Translation is Needed, Early Data is Redefining Understanding of Cancer Progression
♦ In 2008, a team led by Dr. Timothy Leybecame the first to sequence an entire cancer genome using a patient’s own cancerous cells. The cancer they chose to sequence first was AML.
♦ Today hundreds of AML genomes have been sequenced (between TGI and other WGS initiatives) that are mapping genetic mutations impacting the etiology, prognosis, responsiveness to therapy and progression of AML.

Investigation of the mutational spectrum associated with relapse by comparing de novo AML with relapse genomes using deep sequencing. Results provided clonal evolution patterns precisely at relapse and discovered novel, recurrently mutated genes (for example, WAC, SMC3, DIS3, DDX41 and DAXX) in AML. Two major clonal evolution patterns were observed: (1) the founding clone in the primary tumor gained mutations and evolved into the relapse clone, or (2) a subclone of the founding clone survived initial therapy gained additional mutations and expanded at relapsesubclone of the founding clone survived initial therapy, gained additional mutations and expanded at relapse. Chemotherapy failed to eradicate the founding clone and DNA damage caused by cytotoxic chemotherapy may shape clonal evolution and resistance.

Model for evolution of genetic changes in acute myeloid leukemia
♦ A hypothetical model in which nonpathogenic somatic mutations (1–3) acquired over the lifespan of a stem cell are propagated in the malignant clone after it acquires a critical initiatinglifespan of a stem cell are propagated in the malignant clone after it acquires a critical initiating mutation (4). Mutation 5 is a progression mutation that cooperates with the AML‐initiating mutation 4 to contribute to AML development. Other mutations (represented by 6 and 7) do not cooperate with the AML‐initiating mutation 4, and do not contribute to AML development. These subclones are lost or fail to expand to the limit of detection by sequencing studiesThese subclones are lost, or fail to expand to the limit of detection by sequencing studies.
