If the subjects qualify to take part in this research study, they will undergo the following procedures.
Subjects will be asked to abstain from alcoholic beverages (24 hours), grapefruit products, herbal supplements/teas, and over-the-counter medications (48 hours) prior to the study visits. There will be two study periods in this study. During each period all the subjects are outpatients and there will be no overnight stay. During each study period, the subjects will come to the University of Florida Clinical Research Center (UF CRC) three times: on Day -1, Day 1, and Day 2, respectively. Subjects will report to the UF CRC the day before Day 1 (i.e. Day -1) to have clinical lab test and urine pregnancy test (female only). Subjects will come to UF CRC at 6:30 a.m. on Day 1 and Day 2 of each study visit. During the morning of each study period (around 8:30 am) subjects will be randomly assigned to receive a single oral dose of dasatinib 20 mg either with or without a single oral dose of imatinib 400 mg administered one hour prior to dasatinib. After the first study visit, the subjects will return one to two weeks later for the second study visit, receiving the opposite treatment. The treatment order for the study visits will be assigned randomly. The end point measures for this study are plasma concentrations of dasatinib. A total of twelve (12) blood samples will be collected for a total amount of 84 ml (about 3 ounces or about 6 tablespoonsful) for each subject during each study period.
