Understanding Treatment



GLEEVEC® (imatinib mesylate) tablets is not a cure for KIT+ GIST. GLEEVEC targets several different proteins, including Bcr-Abl, PDGF, SCF—and the KIT protein, which is believed to cause most GISTs. Tests done in a laboratory environment (in vitro) show that GLEEVEC blocks KIT activity in GIST so that most of the cancer cells stop growing and multiplying, and some cancer cells even die.
