Purpose:

The main purpose of this study is to learn how patients with myelodysplastic syndrome (MDS) respond to the study drug dasatinib. The study drug, dasatinib, has been approved by the U.S. Food and Drug Administration (FDA) for treatment of leukemia, but has not been approved for the treatment of other kinds of cancer. The use of dasatinib in this study is considered experimental.


Study summary:

Study Core Period: The first 16 weeks after the initial dose of dasatinib is called the Study Core Period. Patients who are eligible and chose to participate in this study should expect to take 100 mg of dasatinib daily for 8 weeks. If the study doctor believes that they have not achieved a partial response after 8 weeks of treatment, the dose may be increased to 150 mg per day. The study doctor may lower the dosage of dasatinib if the 100 mg treatment is too strong. If the lower dose of dasatinib is still too strong, the study doctor may decide to take the patient off of the study. The patient will continue to receive supportive care as needed during the duration of the trial as well as after completion of the trial. During the Study Core Period, participants will have a study visit every 4 weeks. Complete Blood Counts (CBCs) will be obtained every 2 weeks for study purposes and disease monitoring. Bone marrow aspiration and biopsy will be obtained at screening, and at 8 weeks and 16 weeks of treatment for response assessment. Additional bone marrow aspirations and biopsies may be obtained at any other time, to evaluate the disease process, at the doctor's judgment. A bone marrow aspirate and biopsy must be done at the time of study discontinuation. Study Extension Period: The time after the first 16 weeks of treatment is called the study extension period. If the patient is responding to the treatment, does not experience disease progression or any severe adverse events, the patient may continue dasatinib treatment for up to 48 weeks. If patients continue after 48 weeks, they will be asked to enroll in a separate extension study for future follow up. During the Study Extension Period, participants will have a study visit every 4 weeks. Complete Blood Counts (CBCs) will be obtained every 2 or 4 weeks for study purposes and disease monitoring. Bone marrow aspiration and biopsy will be obtained every 16 weeks. A bone marrow aspirate and biopsy must be done at the time of study discontinuation.

Tablets can be dissolved in juice and then put down an NG/G tube or drank as a solution) - Women of childbearing potential (WOCBP) must have Negative serum or urine pregnancy test within 72 hours prior to start of study drug - Persons of reproductive potential must agree to use adequate birth control throughout treatment and at least 4 weeks after study drug is stopped - Signed written informed consent Exclusion Criteria: - White blood count (WBC) >50,000 off hydroxyurea for >72 hours - Malignancy [other than the one treated in this study] requiring radiotherapy or systemic treatment within past 3 years - Chemotherapy or any agent with activity in MDS or AML concurrent with the study. - Chemotherapy for MDS or AML prior to enrollment not allowed other than Azacitidine or Decitabine >2 months prior to first dose - Concurrent medical condition which may increase the risk of toxicity, including: - Pleural or pericardial effusion - Serious medical condition, unstable medical co-morbidity, psychiatric illness that will prevent subject from signing informed consent form or place them at unacceptable risk if they participate - Cardiac Symptoms, including: - Uncontrolled angina, congestive heart failure or myocardial infarction (MI) within 6 months - Diagnosed congenital long QT syndrome - 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) - Hypokalemia or hypomagnesemia if cannot be corrected - History of significant bleeding disorder unrelated to cancer, including: - Congenital bleeding disorders - Acquired bleeding disorder within 1 year - Ongoing or recent (≤ 3 months) significant gastrointestinal bleeding - Concomitant Medications, consider the following prohibitions: - Drugs generally accepted to have risk of causing Torsades de Pointes(Must discontinue drug 7 days prior to starting dasatinib) - Concomitant use of H2 blockers or proton pump inhibitors with dasatinib not recommended. Use of antacids should be considered in place of H2 blockers or proton pump inhibitors in patients receiving dasatinib therapy. - On-going requirement for treatment with platelet function inhibitor or anti-coagulation. - Must discontinue St. Johns Wort while receiving dasatinib therapy - Must agree that intravenous (IV) bisphosphonates be withheld for first 8 weeks of Dasatinib therapy due to risk of hypocalcemia. - May not be receiving any prohibited CYP3A4 inhibitors - Women: - Positive pregnancy test at baseline - Pregnant or breastfeeding - Prisoners or patients who are compulsorily detained for treatment of either psychiatric or physical (e.g., infectious) illness
