myeloma, Hodgkin's and non Hodgkin's lymphoma)
- Patients must be between 100 to 180 days after ASCT
- Dasatinib use prior to ASCT is allowed

- Patient should be able to provide signed written informed consent; before any study
procedures are performed, subjects will have the details of the study described to
them, and they will be given a written informed consent document to read; then, if
subjects consent to participate in the study, they will indicate that consent by

written consent will include a Health Insurance Portability and Accountability Act

- Sexually active fertile men not using effective birth control if their partners
are WOCBP
- Medical history and concurrent diseases:
- No malignancy (other than the one treated in this study) which required radiotherapy
or systemic treatment within the past 5 years

(within 6 months)

- Any history of clinically significant ventricular arrhythmias (such as
ventricular tachycardia, ventricular fibrillation, or torsades de pointes)
- Prolonged corrected QT (QTc) interval on pre-entry electrocardiogram (> 450
msec)

- 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 (=< 3 months) significant gastrointestinal bleeding
- Any previous history of >= grade 3 toxicity to dasatinib
- Prohibited treatments and or therapies
- Category I 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

halofantrine, levomethadyl, pentamidine, sparfloxacin, lidoflazine
- Patient agrees to discontinue St. Johns Wort while receiving dasatinib therapy
(discontinue St. Johns Wort at least 5 days before starting dasatinib)
- Patient agrees that intravenous (IV) bisphosphonates will be withheld for the first 8
weeks of dasatinib therapy due to risk of hypocalcemia
- Other exclusion criteria:
- Prisoners or subjects who are involuntarily incarcerated
- Subjects who are compulsorily detained for treatment of either a psychiatric or
physical (eg, infectious disease) illness
