How Does Sprycel Work?
Protein kinases are proteins found in the body that control cell function, including cell growth. Sprycel works by reducing the activity of BCR-ABL tyrosine kinase, a type of protein kinase that causes the growth of leukemia
cancer cells. By reducing BCR-ABL activity, Sprycel slows down the growth of leukemia cancer cells.
Sprycel has been shown to be effective for the treatment of chronic myeloid leukemia (CML
, a type of leukemia) in clinical studies. In one of these studies, 77 percent of people given Sprycel had a "complete cytogenic response" (when cells with the abnormal chromosome that causes CML are not detectable in the blood and bone marrow), compared with 66 percent of people given Gleevec®
), another leukemia medication.
Another clinical study included people who previously took Gleevec, but stopped responding to it or did not tolerate it. In this study, 62 percent of people given Sprycel achieved a complete cytogenic response. Also, 80 percent of people had not progressed to a worse stage of leukemia after two years of treatment.
