20. KRAS is Difficult To Target Directly
KRAS inhibitor – failed clinical trials
21. Alternatives to Targeting KRAS
1. Block known downstream pathways (between pedal and engine)
Also failing in clinical trials

2. Use genomics to identify currently unknown pathways

39. Summary
• Lung cancer can be treated with a
combination of surgery, radiation, and
chemotherapy depending on the stage
40. Summary
• Lung cancer can be treated with a
combination of surgery, radiation, and
chemotherapy depending on the stage
• We continue to develop new ways to target
lung cancer more directly, with increasing
success
41. Summary
• Lung cancer can be treated with a

chemotherapy depending on the stage
• We continue to develop new ways to target
lung cancer more directly, with increasing
success
• With combinations of these new targeted
therapies the future is very bright
