Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: BASIC_SCIENCE
- Time Perspective: None
- Masking: NONE
- Phase: PHASE1/PHASE2
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~1. Age: patients must be ≥18 years of age and ≤25 years of age at the time of study entry.~2. Diagnosis: Patients must have documented diagnosis of sickle cell disease (Hemoglobin SS Disease or S-Beta 0 Thalassemia) by either high pressure liquid chromatography (HPLC) or Hemoglobin Electrophoresis~3. Disease status: Patients must have at least 2 documented episodes of vaso-occlusive pain in the prior year as defined by an acute episode of pain lasting greater than 24 hours, with no medically determined cause other than a vaso-occlusive event that resulted in treatment with oral or parenteral opiates or with a parenteral nonsteroidal anti-inflammatory drug.~4. Performance Level: Karnofsky ≥80 for patients \>10 years of age and Lansky ≥80 for patients ≤10 years of age. Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.~5. Organ function requirements:~   a. Adequate bone marrow function defined as i. Peripheral absolute neutrophil count (ANC) ≥1000/µL ii. Platelet count ≥100,000/ µL (transfusion independent) b. Adequate renal function defined as i. Creatinine clearance or radioisotope glomerular filtration rate (GFR) ≥70 mL/min/1.73 m2 or ii. A serum creatinine based on age/gender c. Adequate Liver Function Defined As: i. Total bilirubin (sum of conjugated + unconjugated) ≤1.5 times upper limit of normal (ULN) for age, and ii. serum glutamate pyruvate transaminase (SGPT or ALT) \<2.5 upper limit of normal. For the purpose of this study, the ULN for SGPT is 45 U/L iii. Serum albumin ≥2 g/dL d. Adequate cardiac function defined as: i. Shortening fraction or ejection fraction greater than the institutional norm, and ii. Corrected QT interval ≤450 msec~6. Informed Consent: All patients and/or their parents or legal guardians must sign a written informed consent. Assent, when appropriate, will be obtained according to institutional guidelines.~Exclusion Criteria:~1. Chronic transfusion protocol.~   a. Patients currently on a chronic transfusion protocol are not eligible~2. Hydroxyurea Intolerance~   a. Patients who are ineligible for hydroxyurea due to persistent marrow suppression (e.g. thrombocytopenia, neutropenia)~3. Pregnancy or Breast-Feeding~   a. Pregnancy tests must be obtained in girls who are post-menarchal. Males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method.~4. Concomitant Medications~   1. Investigational Drugs: Patients who are currently receiving another investigational drug.~  2. Anti-cancer agents: Patients who are currently receiving other anti-cancer agents.~  3. The following CYP3A4 inducers are prohibited 14 days before the start of imatinib and during the study with imatinib: rifampin, rifabutin, carbamazepine, Phenobarbital, phenytoin, St. John's wort, efavirenz, and tipranavir.~  4. The following CYP3A4 inhibitors are prohibited 7 days before the start of imatinib and during the study with imatinib: azole antifungals (itraconazole, ketoconazole); clarithromycin, erythromycin, diltiazem, verapamil, HIV protease inhibitors (indinavir, saquinavir, ritonavir, atazanavir, nelfainavir); delavirdine.~5. Patients who have an uncontrolled infection.~6. Prior use of Imatinib: Patients who have previously received imatinib are not eligible for study.~7. Patients who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study.~8. Patient is \< 5 years free of a malignancy. Existence of any other malignant disease is not allowed.~9. Patient with Grade III/IV cardiac problems as defined by the New York Heart Association Criteria. (i.e., congestive heart failure, myocardial infarction within 6 months of study).~10. Patients with a history of QT prolongation, need for concomitant use of anti-arrhythmics or other agents known to prolong QT interval, or electrolyte derangement that cannot be corrected to within normal limits prior to initiation of study drug.~11. Patients with a family history of sudden cardiac death.~12. Patient has a severe and/or uncontrolled medical disease other than sickle cell disease (i.e., uncontrolled diabetes, chronic renal disease, or active uncontrolled infection).~13. Patient has known chronic liver disease (i.e., chronic active hepatitis, and cirrhosis).~14. Patient has a known diagnosis of human immunodeficiency virus (HIV) infection.~15. Patient had a major surgery within 2 weeks prior to study entry.
