Ability to understand and the willingness to sign a written informed consent document~EXCLUSION CRITERIA:~1. No prior CLL-related treatment within 28 days before starting treatment with dasatinib.~2. No concurrent use of other investigation agent.~3. Concurrent medical condition which may increase the risk of toxicity, including:~   * Uncontrolled or significant cardiovascular disease, including:~     * Myocardial infarction, congestive heart failure or uncontrolled angina within 6 months~    * Diagnosed congenital long QT syndrome~    * Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsade de Pointes)~    * Prolonged QTcF interval on pre-entry ECG (\> 450 msec)~    * 2nd/3rd degree heart block, uncontrolled hypertension or heart rate \< 50~  * History of significant bleeding disorder unrelated to CLL, including:~     * Diagnosed congenital bleeding disorder (e.g., von Willebrand's disease)~    * Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies)~    * Ongoing or recent significant GI bleeding within 3 months~  * Hypokalemia or hypomagnesemia if it cannot be corrected~  * Pleural or pericardial effusion of any grade~  * Past or current malignancy, except for:~     * Cervical carcinoma Stage 1B or less~    * Non-invasive basal cell and squamous cell skin carcinoma~    * Malignant melanoma with a complete response of a duration of \> 10 years~    * Other cancer diagnoses with a complete response of a duration of \> 5 years~  * Major systemic or other illness including active infection or active secondary malignancy that would, in the opinion of the Investigator, interfere with the patient's ability to comply with the protocol, compromise patient safety, or interfere with the interpretation of the study results~4. No history of allergic reaction to dasatinib.~5. Use of Prohibited Concomitant Medications~   Subjects requiring any of the following prohibited therapies should not be enrolled:~  * Bisphosphonates Intravenous bisphosphonates will be withheld for the first 8 weeks of treatment due to the risk of hypocalcemia. After the need for Ca2+ supplementation has been assessed and levels documented to be \>LLN, subjects on prior bisphosphonate may be restarted with caution at the Investigator's discretion.~  * CYP3A4 Inhibitors/Inducers/Substrates Dasatinib is primarily metabolized by the CYP3A4 enzyme. Therefore, potent inhibitors of CYP3A4 are prohibited during study; for such medications, a wash-out period of ≥ 7 days is required prior to starting dasatinib. Subjects should be advised not to consume substantial quantities of grapefruit juice.~  * Drugs that may increase dasatinib plasma concentrations:~   CYP3A4 Inhibitors: Dasatinib is a CYP3A4 substrate. Concomitant use of dasatinib and drugs that inhibit CYP3A4 (e.g., ketoconazole, itraconazole, erythromycin, clarithromycin, ritonavir, atazanavir, indinavir, nefazodone, nelfinavir, saquinavir, telithromycin) may increase exposure to dasatinib and should be avoided.~   In patients receiving treatment with dasatinib, close monitoring for toxicity and a dasatinib dose reduction should be considered if systemic administration of a potent CYP3A4 inhibitor cannot be avoided.~   -Drugs that may decrease dasatinib plasma concentration: CYP3A4 Inducers: Drugs that induce CYP3A4 activity may decrease dasatinib plasma concentrations. In patients in whom CYP3A4 inducers (eg, dexamethasone, phenytoin, carbamazepine, rifampicin, phenobarbital) are indicated, alternative agents with less enzyme induction potential should be used. If dasatinib must be administered with a CYP3A4 inducer, a dose increase in dasatinib should be considered and approved by the principal investigator.~   -Drugs that may have their plasma concentration altered by dasatinib: CYP3A4 Substrates: CYP3A4 substrates known to have a narrow therapeutic index such as alfentanil, astemizole, terfenadine, cisapride, cyclosporine, fentanyl, pimozide, quinidine, sirolimus, tacrolimus, or ergot alkaloids (ergotamine, dihydroergotamine) should be administered with caution in patients receiving dasatinib.~  * Less-potent inhibitors, inducers, and substrates of CYP3A4 are restricted.~  * St. John's Wort (Hypericum perforatum):~   May decrease dasatinib plasma concentrations unpredictably. Patients receiving dasatinib should not take St. John's wort.~  * Antacids Nonclinical data demonstrate that the solubility of dasatinib is pH dependent. Simultaneous administration of dasatinib with antacids should be avoided. If antacid therapy is needed, the antacid dose should be administered at least 2 hours prior to or 2 hours after the dose of dasatinib.~  * H2 Blockers/Proton Pump Inhibitors Long-term suppression of gastric acid secretion by H2 blockers or proton pump inhibitors (eg, famotidine and omeprazole) is likely to reduce dasatinib exposure. 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.~  * Medications that prolong QT Interval~   Subjects enrolled in this study should not take or begin to take concomitant medications known to prolong the QT interval. If such medications are already being taken by the patient before study starts, a wash-out period of ≥ 7days is required prior to starting dasatinib. Medications known to prolong the QT interval and/or are generally accepted to have a risk of causing Torsades de Pointes ventricular arrhythmia are (see http://www.qtdrugs.org/medical-pros/drug-lists/drug-lists.htm):~  * 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 Should the Investigator believe that beginning therapy with a potentially QT prolonging medication (other than the ones explicitly prohibited) is vital to an individual subject's care, the Investigator must check that the subject's prior on-therapy ECG has not shown a QTcF ≥ 450 msec or an increase in QTc ≥ 60 msec over the baseline value.~     * Anticoagulants and Medications that inhibit Platelet Function Caution should be exercised if patients are required to take medications that inhibit platelet function or anticoagulants.~   Subjects enrolled in this study should not take concomitant medications that durably inhibit platelet function. For such medications, a wash-out period of ≥ 7days is required prior to starting dasatinib. (Agents that inhibit platelet function transiently or inhibit coagulation by other mechanisms are restricted.)~   Medications that directly and durably inhibit platelet function include:~  * aspirin or aspirin-containing combinations, clopidogrel, dipyridamole~  * tirofiban, dipyridamole, epoprostenol, eptifibatide, cilostazol, abciximab, ticlopidine, cilostazol~   Medications that directly and durably inhibit anticoagulation include:~  * warfarin, heparin/low molecular weight heparin \[e.g., danaparoid, dalteparin, tinzaparin, enoxaparin\]~  * Exceptions: low-dose warfarin for prophylaxis to prevent catheter thrombosis, and heparin for flushes of IV lines.~6. Women who are pregnant (including having a positive pregnancy test) or breastfeeding, or unable/unwilling to practice an acceptable method to avoid pregnancy for the entire study period and for at least 4 weeks after cessation of study drug, or men who are sexual partners thereof.~   * Sexually active women of childbearing potential (WOCBP) must use an effective method of birth control during the course of the study, in a manner such that risk of failure is minimized. Prior to study enrollment, WOCBP must be advised of the importance of avoiding pregnancy during trial participation and the potential risk factors for an unintentional pregnancy.~  * All WOCBP MUST have a negative pregnancy test prior to first receiving dasatinib. If the pregnancy test is positive, the patient must not receive dasatinib and must not be enrolled in the study.~7. Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious) illness
