Definitions

  • Lung cancer has been the most common cancer in the world since 1985, with approximately 163,510 deaths expected to occur in 2005 in the United States. Even with current treatments involving surgery, chemotherapy, and/or radiotherapy, overall 5-year survival in the United States is still only approximately 15 percent; in developing countries, 5-year survival rates are about 9 percent (Parkin et al., CA Cancer J. Clin . (2005) 55:74-108).
  • the overwhelming majority of lung cancers in both sexes can be attributed to smoking. However, approximately 10% of lung cancers arise in individuals who smoked less than 100 cigarettes in a lifetime (“never smokers”).
  • gefitinib tyrosine kinase inhibitors
  • TARCEVATM OSI Pharmaceuticals, Genentech.
  • gefitinib and erlotinib are the only two targeted agents clinically available for treatment of human non-small cell lung cancer (adenocarcinoma, squamous cell carcinoma and large cell carcinoma).
  • Tumors arising from mutant EGFR require the continuous expression/activity of the oncogene for survival. This is based on the regression of mutant EGFR lung tumors that were treated with erlotinib and gefitinb, and has also been demonstrated for lung tumors arising in mice with controlled expression of oncogenic egfr (Politi et al., Genes Dev . (2006) 20:1496-1510) and kras (Fisher et al., Genes Dev . (2001) 15:3249-3262).
  • the mutant oncogene may alter a normal cell so that continued expression or function of the oncogene is required to prevent the cell from entering an apoptotic (or differentiation) pathway. Very likely, the protein encoded by the mutant oncogene activates multiple signaling pathways in such a way that sudden loss of a signal dependent on a mutant oncoprotein removes a block to other signals that direct apoptosis or differentiation.

  • All of the adenocarcinoma cell lines with EGFR mutations shown in Table 6 express wild type KRAS. Conversely, the lines with wild type EGFR in Table 6 carry a mutation in exon 2 of KRAS, resulting in a missense amino acid substitution in codons 12 or 13. In H358 and H2030, this exon 2 mutation results in a G12C amino acid change in KRAS. In H1734, there is a G13C substitution, in KRAS. Introduction of a G12C-KRAS allele-specific siRNA into the H2030 cell line results in growth arrest, suggesting that this cell line is dependent on expression of mutant KRAS for growth. All adenocarcinoma cell lines with mutant KRAS in Table 6 are resistant to erlotinib and express wild type EGFR.

  • SKI-267077 caused a dose-dependent decrease in DNA synthesis.
  • SKI-267077 induces cell cycle arrest at the G1 phase.
  • Cell cycle progression in the presence of SKI-267077 was determined by FACS analysis of H2030 cells that were treated for 24 hours.
  • SKI-267077 treatment resulted in a reduction of the percent of cells in the S phase ( FIG. 2A ) of the cell cycle and a concomitant increase in the percent of cells in the induce G1 phase ( FIG. 2B ).
  • SKI-267077 stimulates the enzymatic activity of caspase 3/7.
  • Treatment of H2030 with SKI-267077 for 48 hours lead to an increase in the activity of caspase 3/7 ( FIG. 3 ).
  • the dose response studies were done with the following standard procedure. First, the cells were counted and dispensed at 250 cells/well into 384-well microplates with compound. The cells were incubated for 48 hours at 37 C to complete treatment, and then alamar blue was added for an additional 48 hours. Finally, alamar blue reduction was measured and the data was loaded into ORIS, our data screening acquisition platform. Table 18 provides a summary of these experiments.
