Nilotinib
"Was on Gleevec when I was first diagnosed with  Gastrointestinal Stromal Tumor Cancer  at 17, and for me the 800 mg was unbearable. Way too many side effects to handle and being brand new to the question "how do you tolerate the medicine?" I grew to dread Gleevec and went off Gleevec about 2 years and 7  long months later, and after a relapse of growths showed up, was put onto Tasigna. Though fairly new to it, I have had little side effects thus far and seem to tolerate 700mg much easier on this medicine than Gleevec. Definitely a medicine that is changing how I'm able to define my qaulity of life living with Stage 4 cancer. Hope all GIST patients are able to receive the benefits of Tasigna,(or Gleevec if that works best for you and your Cancer's Xenon Mutation)"
