  • Platelet count ≥ 50,000/μL
  • Total bilirubin < 2.0 times the institutional upper limit of normal (ULN)
  • Hepatic enzymes (AST, ALT ) ≤ 2.5 times the institutional ULN
  • Serum creatinine < 2.0 times the institutional ULN
  • PTT within institutional normal limits
• Ability to take oral medication (dasatinib must be swallowed whole)
• Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (sensitivity < or = 25IU HCG/L) within 72 hours prior to the start of study drug administration

• Signed written informed consent including HIPAA according to institutional guidelines

Exclusion Criteria:

• Cardiac Symptoms, consider the following:

  • Uncontrolled angina, congestive heart failure or MI within (6 months)
  • Diagnosed congenital long QT syndrome
  • Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes)
  • Prolonged QTc interval on pre-entry electrocardiogram (> 450 msec)
  • Subjects with hypokalemia or hypomagnesemia if it cannot be corrected

• History of significant bleeding disorder unrelated to cancer, including:

  • Diagnosed congenital bleeding disorders (e.g., von Willebrand's disease)
  • Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies)
  • Ongoing or recent (< or = 3 months) significant gastrointestinal bleeding

• Concomitant Medications, consider the following prohibitions:

  • Drugs that are generally accepted to have a risk of causing Torsades de Pointes including: (Patients must discontinue drug 7 days prior to starting dasatinib.) quinidine, procainamide, disopyramide, amiodarone, sotalol, ibutilide, dofetilide,erythromycin, clarithromycin, chlorpromazine, haloperidol, mesoridazine, thioridazine, pimozide, cisapride, bepridil, droperidol, methadone, arsenic, chloroquine, domperidone, halofantrine, levomethadyl, pentamidine, sparfloxacin, lidoflazine.
  • The concomitant use of H2 blockers or proton pump inhibitors with dasatinib is not recommended. The use of antacids should be considered in place of H2 blockers or proton pump inhibitors in patients receiving dasatinib therapy.
  • Patient agrees to discontinue St. Johns Wort while receiving dasatinib therapy
  • Patient agrees that IV bisphosphonates will be withheld for the first 8 weeks of dasatinib therapy due to risk of hypocalcemia.
  • Patient may not be receiving any prohibited CYP3A4 inhibitors
