Bills for Cancer Research 1. The National Cancer Act - Enacted December 23, 1971 2. National Cancer Amendments - Enacted July 23, 1974 3. Biomedical Research and Research Training Amendments - Enacted November 9, 1978 4. Health Research Extension Act - Enacted November 20, 1985 5. Health Omnibus Program Extension - Enacted November 4, 1988 6. National Institutes of Health Reform – Enacted January 15, 2007

Resource spent for cancer research & treatment NCI has spent some $90 billion Some 260 nonprofit organizations in US have dedicated themselves to cancer (more than the number established for heart disease, AIDS, Alzheimer’s disease, and stroke combined). These 260 organizations spent > $2.2 billion annually The United States has spent > a trillion dollars for war on cancer

Signal transduction pathways
8
Cancer – a Disease of Genome Cancer is a disease characterized by the uncontrolled growth of abnormal cells in the body. Cell growth is regulated by genes encoded in the DNA molecules of the chromosomes. Mutations in those genes overstimulate cell growth, keeping the cell active when it should be at rest.
9
The Human Genome Project Began in 1990, and completed in 2003 The full sequence was completed and published in April 2003.
10
The Cancer Genome Atlas (TCGA) Cancer: errors in DNA uncontrolled growth. Identifying the changes in each cancer’s genome Understanding how such changes drive the disease Providing the foundation for improving cancer prevention, early detection and treatment.
11
The Cancer Genome Atlas (TCGA) 2006 - TCGA began as a three-year pilot National Cancer Institute and National Human Genome Research Institute committed $100 million 2008 - TCGA reported first result: GBM 2009 - began to map 20 cancers. 2011 - 5,000 th case ships to TCGA centers
12
Her2 pathway
13
HER2 overexpression: 20% patients with breast cancer Drugs that target the Her2 protein –Herceptin (Trastuzumab): McAb –Kadcyla (TDM-1): an Ab-drug conjugate, Herceptin attached to a chemo drug DM-1. –Perjeta (Pertuzumab ): McAb –Tykerb (Lapatinib): an oral drug that targets the Her2 protein. Her2 pathway
14
PI3K/Akt/mTOR pathway Growth factor receptor
15
PI3K/Akt/mTOR pathway the most frequently dysregulated in cancer. Implicated in oncogenesis, progression, and resistance to conventional anticancer therapies. Inhibition of this pathway has been shown to halt tumor growth, leading to tumor regression. PI3K inhibitors showed synergistic activity with cytotoxic and targeted agents, and have restored sensitivity to these drugs
16
Afinitor: approved for RCC and ER+ BC Torisel: approved for RCC Buparlisib (BKM120): an oral pan-PI3K inhibitor. BYL719 : PI3K a inhibitor XL147: a selective PI3K inhibitor, XL765: a dual mTOR and PI3K inhibitor Idelalisib: PI3K inhibitor, ? approval for CLL Pictilisib (GDC-0941): PI3K inhibitor IPI – 145: PI3K inhibitor PI3K/Akt/mTOR pathway
17
Cyclin-Dependent Kinase 4 and 6 (CDK4/6) Pathway Palbociclib - "breakthrough therapy" designated by FDA in 2013. The phase II PALOMA-2 trial: The phase III PALOMA-3 trial: LEE011: the most selective CDK4/6 inhibitor LY2835219: CDK4/6 inhibitor
18
The Ras/Raf/MEK/ERK pathway
